1. INSULATE WATER TANK RESERVOIR

2. LOCATION-LOCATION - Required Criteria

4. MOUNTING TEMPLATE

5. DRILL HOLES AND CUT OPENINGS

With insulation foil side down, remove adhesive backing.

Align humidifier so that front side of unit meets long edge of

insulation. Fold insulation up onto sides of humidifier and

press firmly. Apply 5 continuous strips from the tape

provided to seal the foil as shown. The tape will prevent the

sharp duct edges from damaging the foil. Use additional foil

tape to repair damage to the foil. The Insulation MUST be

applied to the tank regardless of the mounting location.

DO NOT INSTALL this unit in an attic period. Do Not

Install this unit in any area that may fall below 35

degrees F. Doing so will void your warranty! The steam

humidifier can be installed in either the warm air supply or the

cold air return ducts; however the preferred location would be

in the warm air supply duct of the system. This humidifier does

not require warm air to evaporate the water in order to provide

humidity, but it will operate more efficiently in the warm air duct

and condensation is less likely to occur on the surrounding cold

surfaces. Efficiency is lost in a return air duct location.

When selecting a location on the duct, be certain that there is

enough room in the duct for the water reservoir. There should be

at least five (5) inches above the reservoir and the reservoir

should not occupy more than about 25 percent of the duct space.

If this criteria can not be met, you should install the unit under

the duct by means of the tank flange. See page 6.

If a suitable means of gravity draining the unit is not available

or cannot be provided, the unit will work with the drain valve

electrically disconnected. Call the Technical Support Hotline

for Instructions.

It is highly recommended but not required that the

use of Fiberglass duct-board with this product

includes an anti-microbial treatment.

Providing Adequate Structural Support for this unit is the

responsibility of the Installer. It is recommended to

reinforce the cut openings with folded lengths of sheet-

metal to provide rigidity to the duct opening. Now the

screws must pass through 3 layers of metal when inserted.

DO NOT install this unit into fiberglass duct without

adequate structural support! Both models weigh

approximately 9 lbs. empty and 15lbs. full of water.

Two mounting templates are provided. Choose the correct

template for your mounting method. Tape the mounting

template to the duct. The template must be leveled using the

top of the cutout on the template. The template should be

located so that the bottom of the reservoir cut-out is flush with

the inside of the bottom of the duct for horizontal duct. Since

most ducts are insulated this additional space, about one (1)

inch, must be accounted for when determining the location

for the bottom of the reservoir cut-out. If you are mounting it

under the duct, make sure the duct is level.

Use an electric drill, with grounded power cord, to drill eight

(8) mounting holes, 1/8" diameter, in the duct. These can be

drilled through the template at the locations indicated on the

template.

A saber saw or tin snips can be used to cut out the water

reservoir opening.

Insert and/or mount the Humidifier and secure it to the duct

with the provided screws.

A. INSTALLING AND WIRING THE HUMIDISTAT

B. OVERFLOW & DRAIN LINES - Required Criteria

Installation instructions for the saddle valve are printed on the

plastic bag containing the saddle valve and its components.

Tap into a 1/2” or 3/4” domestic cold water line. Avoid

connecting to water lines from a Reverse Osmosis system or

De-ionized water systems. The supply water must read a

minimum of 25 ppm in order for the Steam unit to reliably

sense the water.

NOTE: Never install the saddle valve on the bottom of the

water pipe. Sediment in the water pipe may clog the saddle

valve. Flush the line before connecting to the unit.

tightening the hex compression nut, tighten only enough to

assure there are no leaks.

NOTE: Saddle valves do not meet plumbing codes in some

areas. A “T” fitting with a valve may be required to meet code

or, if low water pressure causes frequent water alerts on the

steam humidifier. NOTE: Flush the new water line before

connecting it.

NOTE: The use of City water or Municipal water is preferred.

Softened water is preferred over untreated well water. Specify

the Optional WFA-195 disposable water filter for treating

any water supply that is very high in mineral content.

NOTE: Use a water hammer arrester (WH-100) if water

spikes occur (pipes bang)during fill ups.

When

A temperature sensor is mounted in the water reservoir of the

humidifier. As the water temperature increases to about 170

degrees F, the computer closes a set of blower relay contacts to

start the system fan. When the water cools to about 140 degrees

F, the computer will open the relay contacts to shut off the fan.

This operational sequence drastically decreases the chances of

condensation occurring inside the duct-work.

A humidistat, such as the Model #072000 is required to control

the Steam Humidifier. The humidistat may be installed on the

wall in the living space or on the return air duct. NOTE:

Continuos fan operation should be initiated if the humidistat is

installed on the return air duct! Instructions for installation are

packaged with each humidistat. Follow wiring instructions

carefully!

DO NOT connect any foreign voltage to the “H” terminals of the

humidifier! The Humidifier supplies it’s own control voltage.

Simply connect the two “H” terminals straight to any dry contact

humidistat terminals. If you are using a 3rd party Humidistat

that has powered terminals, you must use an isolating relay

to operate the Steam Humidifier. Failure to do so will result

in circuit board failure and will void all warranties.

Schematics on the following pages describe the suggested

interlock wiring arrangement for different HVAC systems.

Interlocking may be performed on systems that provide a 24vac

NEC Class 2 terminal block for system control.

AIR PROVING FEATURE: The Steam Humidifier has an

integrated air proving feature that allows the user to install a sail

switch and/or high humidity switch in the duct and easily

achieve fail safe shutdown in the event of fan/blower failure.

This feature prevents the Steam Humidifier from operating

unless adequate airflow is proven thereby avoiding a saturated

duct condition. WARNING: It is highly recommended to use

an airflow proving device. In particular Duct-Board

applications should always use an airflow proving device.

A factory jumper wire is provided and must be removed when

connecting the sail switch or other field supplied air flow

proving device. Leave the jumper in place if you decide not to

use the airflow proving feature.

IMPORTANT NOTE: If the Steam Humidifier is removed

and disconnected from the system, the blower interlock

circuit must be restored to it's original configuration. Failure

to do so may result in loss of blower operation during cooling

modes!

Use gasket material to seal where the front plate or tank flange

contacts the duct-work. Place the humidifier reservoir into the

opening in the duct and secure with eight (8) sheet metal

screws.

NOTE: If the duct-work will not support the unit in a level

position with the water pan full of water, the duct-work

must be reinforced. Both steam models weigh

approximately 9 Lbs. empty and approximately 15 Lbs.

when full of water.

Because of the high output of this Humidifier, it must not be

operated without the blower operating. The steam

humidifier is designed to be "Dominant" over the HVAC

System Blower. The "System" Blower will be operated by the

humidifier when the water tank temperature reaches 170

degrees F. A minimum of 800 cfm @ 800-900 fpm is required for

proper operation of the steam humidifier. Lower velocities may

result in excessive condensation inside the duct. See Air Proving

Feature on the next column! See Variable Speed on Page 7.

The use of an overflow line and drain line is always required.

Use the supplied 1/2” ID high temperature hose. Slip the hose

over the 1/2” OD “T” drain fitting and use a hose clamp to

secure. Route the hose to a suitable drain, avoiding kinks,

traps and sharp objects. DO NOT route the hose above the

humidifier. Failure to install all necessary drain lines may

result in water leaks during normal operating conditions,

and voids all warranties.

B. FIELD WIRING

IMPORTANT: Dedicated fused circuits and outlets of the

proper voltage and current ratings must be provided. Use a

NEMA 5-20R receptacle for the S2000 and a NEMA 6-15R

receptacle for the S2020. All wiring must conform to local and

national codes. Failure to do so will void all warranties.

DO NOT cut off the grounded plug and/or hard wire this unit to

line voltage! DO NOT use extension cords to operate this unit!

Doing so will void all warranties.

When routing the S2000 drain hose into a condensate pump,

be sure to cut the end of the hose at a sharp angle to prevent

the hose from bottoming out in the pan. It could result in

poor draining or no draining at all. Failure to do so may

result in water backing up into the S2000 reservoir and

eventual overflow. See Figure 5.

Heat Pump System and Steam Humidiﬁer

The latest improvement to the Field Controls humidifiers is the new

“Airflow Interlock Feature” provided on the low voltage terminal

block. Due to popular demand we have made it easier for you to

achieve fail safe lockout in the event the fan or blower on the

HVAC system does not operate when called upon. A high humidity

or airflow proving device is necessary.

You must still determine the type of proving device you want to

use. We recommend our new Model APD switch. But then all you

have to do is connect two low voltage wires from your air proving

device straight to the Steam Humidifier’s “A” terminals. No

additional field relays or components are needed.

The Steam Humidifier monitors the airflow circuit anytime it is

operating the blower on the HVAC system. If the Steam

Humidifier detects a loss of airflow longer than 1 minute, it will

shutdown the heating element and stop producing eam to avoid

saturating the duct.

You must test the air proving device when you install it to make

sure it will function properly. WARNING: DO NOT perform this test

with the wires connected to the Steam Humidifier. Temporarily

disconnect them. Refer to Figure 11.

1. After installing the air proving device, test for continuity across

the normally open contacts with the fan/blower off. You should

read infinity (no continuity) when the fan/blower is off.

2. Turn on the fan/blower at the thermostat and test for continuity

across the normally open contacts with the fan/blower running.

You should now read continuity (a complete circuit) when the

fan/blower is running.

the room needed to install the unit in a certain location. The data can also be used to determine the minimum duct size the

Steam Humidifier can be inserted into. The Steam Humidifier should not obstruct more than 25% of the cross sectional area of

the selected duct. For Example: The humidifier tank measures 8 inches wide (including the flange) times the length of 11.6

inches=92.8 square inches. We are only concerned with the obstruction on a flat plane. Which is why the flange is taken into

account but not the depth of the tank. This assumes an up-flow configuration. If the configuration is horizontal, then the Steam

Humidifier will obstruct approximately 70 square inches of duct area. The tank flange is no longer a factor.

At 92.8 square inches, the smallest duct plenum that can accommodate the Steam Humidifier mounted internally would be

approximately 20” by 19”. 20x19=380 square inches multiplied by .25 = 95 square inches.

Steam Humidifier square inches of obstruction= 92.8 square inches. Up-flow configuration.

25 percent of 20x19 duct= 95 square inches.

Steam Humidifier square inches of obstruction= 69.6 square inches. Horizontal-flow configuration.

25 percent of 12x24 duct=72 square inches.

In either case, avoid installing the Steam Humidifier on any duct size where the unit will consume more than 25% of the cross

sectional area of the duct at the point of insertion. Doing so may result in turbulent airflow, lower velocities and condensation

inside the duct. Avoid all of these conditions by selecting an “under the duct” location and specify the SC100 decorative tank

cover to give it a finished look.

HVAC System. Notice that some of the locations are X’d out. These are poor locations for

the Steam Humidifer and may result in lower capacity output and/or excessive

condensation. Try to avoid mounting the unit within 2 feet of any 90 degree turns. Allow at

least 5 inches of clearance above the tank. The unit should not be installed within 5 feet of

an Electronic Air Cleaner, 4-5 inch thick Media filters, or a UV Lamp. Caution: UV lamps

may destroy certain plastics/rubber unless shielding is applied to those surfaces. DO NOT

install the Steam Humidifier on a Down-flow HVAC system. Avoid Fiberglass Duct-Board as

it cannot support the weight of the Steam unit when full of water. DO NOT install the Steam

Humidifier in an attic or crawl space exposed to freezing temperatures.

Figure 13.

Remember to insulate the water tank with the supplied insulation

wrap. Under extreme velocities it may be necessary to double

wrap the tank and/or the tank flange to prevent excessive heat

loss. Also remember to use gasket material on the duct opening

to prevent metal to metal heat loss and to prevent against

condensation and air leakage. On under-duct applications, it may

be necessary to insert an Air-Ramp in the duct to induce the

steam out of the tank. Contact Technical Support for assistance.

HUMIDIFIER W/ SCOOP

Suitable locations to install your Steam Humidifer on an Up-flow or Horizontal

It is recommended that humidistat settings of 30-45% not be

exceeded. If condensation is noticed on windows during very

cold outside temperatures, the humidistat setting should be

lowered.

RELATIVE HUMIDITY CHART

The maximum recommended relative humidity for your

home depends upon many factors such as outdoor air

temperature, type and placement of insulation, vapor

barriers, effectiveness of weather stripping, type of windows

and doors (including frames and jambs) and whether or not

storm windows and doors are used. With all these variables it

is nearly impossible to recommend a proper humidity

setting. The best humidistat setting is one that you are most

comfortable with. Also, as the outdoor temperature

fluctuates, it may be necessary to adjust the humidity level of

your system a few times during the heating season.

Refer to the "Relative Humidity Chart" as a starting point for

your proper humidistat setting. Generally, in a tighter and

better insulated house, the humidistat may be set higher than

in a drafty, un-insulated house.

IMPORTANT: If the humidifier is installed in the return air

plenum the humidistat must be located at least five (5) feet

upstream from the humidifier. Fan should be operated in

continuos mode when the humidistat is mounted in the return

air plenum. Mounting the humidistat on an interior wall is

always preferable to mounting on the return duct. But

mounting the humidistat on an interior wall takes more time,

material and labor than a return duct location. Sometimes it

may be impossible to mount a humidistat on an interior wall

and the return duct location is the only solution.

The diagram above should be followed if it is required to operate the fan system at high speed during the humidify operation. Such a

requirement may be necessary if condensation occurs inside the duct-work due to the lower velocities of a variable speed system

when only the fan is running. The “Y” circuit must be wired exactly as shown to achieve the correct operation. This wiring configuration may

result in the loss of the “enhanced” latent effect operations of your variable speed HVAC system. If you do not want this to happen, you

should consider installing a different type of whole house humidifier that does not require dominance over the HVAC fan and full CFM

capacities while operating. Variations on this diagram are available. Contact EWC Controls Technical Support Hotline.

INITIAL START-UP * SEQUENCE OF OPERATION * SERVICE “LED” INDICATORS

11. START -UP & OPERATING SEQUENCE

Once the Steam Humidifier has been installed and the

water, drain, humidistat and blower interlock

connections completed, the humidifier may be started.

A. Disconnect the water line. Turn on the water supply

and flush the line into a bucket. Reconnect the water line.

B. Set the humidistat to a setting higher than the room

RH level.

C. Plug the S2000 Humidifier line cord into a 120

VAC, 20 amp source. (240VAC,15amp for S2020).

D. The Green "POWER" LED should blink rapidly and

the drain valve will open momentarily upon initial start

up. The "FILL" LED will illuminate and water should

begin to fill the Water Pan. The Power LED will now

blink slowly.

E. When the water has reached the probe level the

"FILL" lamp and fill valve will be turned off, and the

"HEATER" LED and heater element will be turned

on. The “POWER” LED will blink slow and steady.

F. Once the water reaches 170 deg. F. the "BLOWER"

LED will illuminate and the system blower should start

up.

G. If the above steps have been successfully completed,

the humidifier is operating properly.

A. POWER: In normal standby mode, when the

humidistat is not calling for humidity and the power

cord is plugged in, the "POWER" LED should be

blinking slowly. If the green "POWER" LED is not

flashing when there is power to the unit, the CPU and/or

circuit board may have failed.

B. FILL: When the humidistat closes, on a call for

humidity, the "FILL" LED is illuminated, the Solenoid

Valve is open and the water reservoir is filling.

C. HEATER: When the water reaches it's proper level

the valve closes, the "FILL" LED goes out, the

"HEATER" LED is illuminated, and the Heater begins

to heat the water.

NOTE: If the humidifier is unplugged while in

steaming operation and then plugged back in, A

rapid flashing of the “POWER” LED will occur

and all other functions will stop! The unit wants to

perform a water probe test, but cannot perform

this test until the water cools down. Simply wait

until the unit cools down and it will resume

normal operations. To accelerate a cool down,

simply turn the HVAC system fan on via the

thermostat.

D. BLOWER: When the water in the reservoir reaches

approximately 170 deg. F. the "BLOWER" LED will

be illuminated and the interlock wiring should turn the

system blower on. Depending upon the water and

ambient temperatures, it may take anywhere from four

to twelve minutes for the water to heat to 170 deg. F. If

the humidistat remains closed the "HEATER" and

"BLOWER" LED's will both be illuminated at the same

time and the "POWER" LED will be blinking slowly.

E. The "FILL" LED will illuminate and the water

reservoir will refill at irregular intervals, depending on

the boil off rate. The "HEATER" LED should remain

illuminated unless the humidistat opens or the

humidifier enters a drain cycle or failure mode.

F. DRAIN: This LED will be illuminated when the

microprocessor cycles the humidifier into a

Maintenance Mode. After a fan forced cool down

period, the water is allowed to drain at 140 degrees F.

The drain valve will then close and the fill valve will

open to refill the reservoir and resume normal operation.

This mode will last about one hour and the

microprocessor will automatically restart the unit

afterwards, if there is a call for humidity. This drain

cycle will occur once every 8-12hours, to reduce the

mineral concentration in the tank and let the heater cool-

down. That will shed most deposits that have built up

on the heater. NOTE: The "POWER" LED will

blink rapidly during Maintenance mode.

NOTE: A unique feature of the “S” series humidifiers

is called “Fill on Request”. The unit will not refill with

water after a maintenance cycle, unless there is a

demand for humidity from the humidistat. This

ensures that the unit will not sit idle with standing

water, which can stagnate over time.

G. FAILURE LED'S: When service is required,

these LED's will illuminate. If the humidifier enters a

failure mode, it must be manually reset by

disconnecting the power and then reconnecting it. If

the “Air” failure LED occurs, simply turn the

Humidistat off or down then back up again to reset.

WATER: This will occur when the reservoir is not

filling up with water, not filling fast enough or the

microprocessor cannot recognize that the water is

touching the probe. Reverse Osmosis water or purified

(distilled/deionized) water sources should be avoided,

unless the final feed water measures at least 25 ppm

conductivity.

HEATER: This will occur if the humidifier is not

boiling off water during the "HEATER" cycle. Water

in the reservoir is not reaching 170 deg. F. temperature,

or the unit has not detected a request for water in a 50

minute steaming time period. Both red LED’s will

illuminate in this condition.

AIR: This will occur if the humidifier detects a loss of

air flow for more than 4 minutes. A field supplied air

proving device must be installed, wired and tested.

THERMISTOR: This will occur if a short or open is

detected in the temperature probe.

12. SERVICE “LED” INDICATORS

14. SERVICE INDICATORS

Seven LED lamps provided on the front panel indicate the

functional status of the humidifier as shown in Figure 7 below.

Unplug the power cord from the 120 volt source for

S2000 (240 volt for S2020) and allow the water to cool for

at least 30 minutes prior to removal.

Turn off the water supply at the saddle tapping valve.

Remove the cable assembly wire plug from the top of the

plastic control housing.

Drain the water with the manual drain valve. NOTE: The

drain valve will be hot if the humidifier has not been

allowed to cool.

Disconnect the water and drain lines. NOTE: Some water

may drain out of the water line. Have a small container

ready to catch the water.

NOTE: Although the water has been drained, some water

may still remain in the humidifier reservoir along with

sediment. Be careful not to tip the unit over when

removing it from the duct.

Remove the eight (8) screws from the front mounting

plate.

Slide the humidifier out of the duct.

Remove the two (2) screws holding the tank baffle to the

pan flange and remove the baffle from the unit. Scrape all

mineral deposits from the baffle and wash baffle off as

described in step J. Remove the Anode from the baffle

plate and purchase a new one. Operating the unit without

the Anode will degrade the performance and increase

maintenance.

Use a putty knife to scrape the minerals from the sides and

bottom of the water reservoir. DO NOT scrape on the

small temperature probe, or the heater element. Use a soft

emory cloth or stiff nylon brush. If necessary, fill the tank

with vinegar and let it sit for several hours or even over-

night allowing the scale to soften and making it easier to

remove.

Carefully scrape the Water Level Probe to remove

mineral deposits. Use soft emory cloth if necessary.

Clean the Water Probe Insulator, inside the pan, with a

cloth and 50-50 mixture of water and vinegar, rinse with

fresh water. Inspect for any mineral deposits on the plastic

insulator. Repeat cleaning if necessary and thoroughly

dry. Use a small nylon brush to clean deposits off the

heater element and thermistor probe. Be careful not to

damage any of the components.

Rinse out the reservoir. Be careful to keep water off of the

wiring compartment and the front cover of the humidifier.

Allow the unit to dry thoroughly before using!

Reinstall the tank baffle and tighten the two (2) screws.

Re-install the unit in the duct and connect the water line and

the drain lines. Store the unit in this condition for the

summer, or continue to the next step.

START -UP

Turn on the water supply. Inspect the water connections and

drain fittings for leaks.

Plug-in the S2000 power cord to the 120 VAC (240 VAC for

S2020) grounded outlet. DO NOT use an extension cord.

1. The green POWER light should blink rapidly until it

detects a demand to humidify, then it will blink slowly.

2. If the humidistat is calling for humidity the water

valve will energize and the water pan will fill with water.

3. The Heater element will energize to heat the water, and

the Fan will start up to distribute the moisture

Maintenance and inspection of the unit requires removal

of the humidifier from the duct. This can be done

following these steps.

13. MAINTENANCE/SPRING SHUTDOWN

Proper maintenance and removal of mineral deposits is still

required on your steam humidifier in order to optimize

performance. Annual cleaning is a must and more frequent

cleaning may be necessary depending on the mineral content

of the water in your area.

A post winter cleaning and shutdown, will prevent hard

deposits from accumulating inside the bin, while the

humidifier is idle over the summer. Do not allow the unit to sit

idle for long periods without a proper cleaning and shutdown.

Failure to do so will affect the performance of your steam

humidifier.

1. The water pan temperature has not reached a high enough

temperature to activate the "Blower" relay, about 170

degrees Fahrenheit. This takes several minutes after the

"HEATER" LED is illuminated. Depending on the water

temperature and the surrounding condition, this may take

up to 12 minutes. If the problem continues, the heater

element may be defective or the thermistor temperature

probe may be defective. Contact the Technical Support

Hotline.

Red Service Light (error #1) is on constantly.

THERMISTOR FAILURE ...This is an indication that the

temperature probe is open or shorted to ground. May also

indicate the probe has detected a pan temperature below 32

degrees F. Or in excess of 230 degrees F., resulting in a total

shutdown. Try to reset the unit by unplugging the cord and

reconnecting, or call Technical Support.

Red Service Light (error #2) is on constantly.

WATER FAILURE ...This is an indication that the water fill

time has been exceeded. The water level did not reach the

probe tip in the given amount of time. It may also indicate

an unsuccessful drain cycle.

1. The water line is shut off at the saddle valve.

2. The water line is crimped or pinched.

3.The water valve inlet screen is plugged. Remove the

water line from the unit and check the screen found inside

the inlet side of the valve.

4.Unit is connected to a water source which is distilled,

over-filtered, de-mineralized, or from a reverse osmosis

system. Minimum 25 ppm water conductivity is

required. *The unit supply water must contain dissolved

solids in the water, or the processor will not be able to

detect the water level.

5.The water valve may be defective and must be replaced

See replacement parts.

6. The drain valve is unplugged or defective.

7. Debris is clogging the drain valve or drain line.

8. Reset the unit by unplugging the power cord and re-

connecting.

Both Red Service Lights (error #3) are on constantly.

HEATER FAILURE...This is an indication that the water

temperature is not increasing or reaching the boiling

point.

1. Faulty heater element or faulty wire connection.

2. This can happen if the unit is operated without water

in the pan as a result of a water level probe malfunction,

due to lack of maintenance. The pan boils dry and over-

heats the water pan. If this condition occurs, call the

Technical Support Hotline.

3. The unit has operated for 45-50 minutes without a

request for water, due to a leaking water fill valve, which

is filling the tank continuously.

Both Red Service Lights (error #4) are flashing.

AIRFLOW FAILURE … This is an indication that the

system blower is not running or the blower/fan proving

device has failed, is malfunctioning, or is not wired

correctly. Check the blower motor and the interlock

wiring. Refer to page 4, Figure 11.

If the humidifier seems to operate in a random manner

that doesn't seem to fit any of the pre-described

conditions, check the following:

1. Check to make sure that the wires used to connect the

humidifier to the humidistat are separate wires and not

part of a multi-wire bundle used to hook up the furnace

thermostat or any other device. The associated close

wires may create an induced voltage in the humidistat

wiring.

2. Make sure that the water level probe and plastic

insulator are clean and free of mineral build-up. It may

become electrically conductive to ground, sensing a false

indication that the water level is correct.

3. If the electric solenoid valve makes a loud noise when it

closes, install an optional water hammer arrester to absorb

the spike. Frequent or erratic water fill cycles can be due

to air turbulence, when mounted in the supply air plenum.

4. The water probe uses the natural conductivity of the

water, to determine the proper water level in the reservoir.

Water that has been de-mineralized or over filtered may

not allow the unit to function properly. Minimum 25 ppm

of total dissolved solids must be present in the water.

Add approximately 1 tablespoon of salt to the tank, to

temporarily fix this problem.

5. These steam humidifiers must be connected to

dedicated outlets of the proper current and voltage ratings.

The use of extension cords is not recommended.

DO NOT cut off the grounded plug and/or

hard wire this humidifier to line voltage.

This will void the warranty.

Smart Digital Humidistat

Installation and Owner's Manual

The 072000 is a digital humidifier control

that can automatically adjust the indoor

humidity set point as the outside air

temperature changes. This intelligent

control will maintain accurate humidity

levels and a more comfortable indoor

environment.

The actual indoor relative humidity is

always displayed on the LCD screen. When

the or down keys are pressed, the

humidity set point is displayed and can be

adjusted using the up and down arrow

keys.

An outdoor temperature sensor is included,

and must be connected in order to fully

utilize the features of the 072000. The

outdoor temperature sensor allows the

humidistat to automatically adjust the

humidity set point, to avoid condensation on

windows. It is also a convenient way to read

the outdoor air temperature at any time.

The outdoor sensor is not required to

use the Humidistat in the basic or

manual mode.

The 072000 operates on 24vac, and has

a set of isolated dry contacts for

activating the humidifier. Terminals are

also provided for the Outdoor air

Temperature Sensor. (Part# OAS)

The 072000 can be installed on the

return air duct or, it can be installed on an

interior wall within the conditioned

interior wall installation. NOTE: If the

return air duct is chosen as the location,

the HVAC fan should be set to run

continuously, in order to obtain an

accurate sampling of the actual living

space relative humidity condition.

ELECTRONIC STEAM POWER HUMIDIFIERS

MODEL # S2000 AND S2020

APPLICATION NOTE

AN 131

SUPPLEMENT TO THE

The Field Controls Steam Humidiﬁer now comes equipped with a factory installed Z100, which acts

as a sacriﬁcial metal. Put simply, minerals in the water will attack and cling to the Z100. The

minerals will not attack the other components inside the humidiﬁer as long as the Z100 is present

and active.

This results in a dramatic decrease in mineral and scale build up on the critical components inside

the tank. In particular, it means less scale build up on the heating element which is subject to

damage from excessive scaling and over heating. This also means that efﬁciency stays high and

preventive maintenance is faster and easier.

The Z100 is positioned on the bafﬂe plate inside the tank and is easily removed and replaced.

Remember that the Z100ʼs job is to become the target of mineral attack, so it will be heavily

covered with scale and should be replaced annually for best results.

To remove the Z100 you must have already unplugged and shutdown your steam humidiﬁer and

allowed it to cool. The water tank has been drained, the water supply, drain lines and electrical

wiring have been disconnected and the unit has been removed from the duct.

Refer to the blow up view on Page 11. Using a phillips screwdriver, remove the two screws that

hold the bafﬂe plate to the tank. Lift the bafﬂe slightly back to clear the water probe and then straight

up and out of the tank. You can then see the round Z100, or rather what is left of it after a single

season. Notice the heavy scale build up on the Z100 that would have been on your element, if the

Z100 was not there. Use a rag or pliers to grasp the edges of the Z100 and simply unscrew it from

the bafﬂe plate. Rinse off or wipe away any residual scale from the bafﬂe plate and install a new

Z100. Leave a slight gap between the bottom of the Z100 and the bafﬂe plate. Now re-insert the

bafﬂe plate into the tank and secure with the two screws that were removed previously. Itʼs that

simple.

The Z100 can also beneﬁt the older model steam humidiﬁers. Simply lay the Z100 down into the

bafﬂe plate in the same location as the factory installed model. DO NOT lay the Z100 down into the

main tank. It may come in contact with the heating element and damage it. The dimensions of the

bafﬂe plate prevent the Z100 from falling down into the tank.
