3. Safe Installation Requirements 4. Locating The Unit

Installation or repairs made by unqualified persons can result

in hazards to you and others. Installation MUST conform with

local building codes or, in the absence of local codes, with the

National Electrical Code NFPA70-1990 or current edition.

The information contained in this manual is intended for use

by a qualified service technician familiar with safety proce-

dures and equipped with the proper tools and test instru-

ments.

Failure to carefully read and follow all instructions in this

manual can result in unit malfunction, property damage, per-

sonal injury and/or death.

• Seal supply and return air ducts.

• Check to see that filters are installed correctly and are the proper

type and size.

NOTE: It is the personal responsibility and obligation of the customer to

contact a qualified installer to ensure that the installation is adequate and

conforms to governing codes and ordinances.

CAUTION

Do NOT operate unit in a corrosive atmosphere containing chlorine,

fluorine, or any other corrosive chemicals.

The unit is designed for outdoor installation only. Place the unit on a plat-

form at ground level. The unit may be installed on a concrete slab of 48"

(1219mm) x 48" (1219mm) dimensions. Cement blocks on a 3" sand

footing will also work. The slab or blocks SHOULD NOT be in contact with

any part ofthe structure. Check local codes covering zoning, noise, plat-

forms, etc..

If practical avoid locating next to fresh air intakes, vent or bedroom win-

dows. Noise may carry into the openings and disturb people inside.

Avoid installations under roof overhangs without guttering. Water draining

from the roof onto the unit could produce excessive noise, and may cause

ice to build up on coil or fan.

Placement of the unit should be in a well drained area or the unit MUST be

supported high enough so runoff will not enter the unit.

Do not locate unit where heat, lint or exhaust fumes will be discharged on

unit (as from dryer vents.)

Clearances

Minimum clearances, as specified in FIGURE 1, MUST be maintained

from adjacent structures to provide adequate air circulation and room for

service personnel.

While minimum clearances are acceptable for safety reasons, they may

not allow adequate air circulation around the unit for proper operation.

Whenever possible, it is desirable to allowadditional clearance, especially

around the condenser inlet and discharge openings.

Do NOT install the unit in a recessed or confined area that will permit dis-

charged air from the condenser to recirculate to the condenser inlet.

Installation

CAUTION

The unit must be installed with a slope no greater than 1/8" per foot

(10mm per meter), For side to side leveling, the condensate drain

side side MUST always be lower.

The unit MUST be situated in such a way as to provide safe access

for servicing.

The platform may be made of either concrete or pressure treated

wood and MUST be level and strong enough to support the unit's

weight.

Position platform separate from the building's foundation.

Install in a well-drained area, with the top surface of the platform

above grade level and above the average winter snow levels to

prevent coil blockage.

Platform MUST be high enough to allow for proper condensate

drainage.

Installing Duct Collars

Duct collars are supplied with the unit and are attached to the supply and

return openings with the flanges to the inside and must be reversed before

unit's installation.

1.Remove the screws from the collars and reverse them so the flange

is to the outside.

2.Make sure when pushing the collars into place that the "V" flange of

the collars seats into the supply and return holes securely.

3.Re-install screw in each collar so it goes through both of the holes in

the collar end. It does not matter how the ends of the collar overlap

in order to accomplish this.

FIGURE ;3 I Duct Collar Installation

Condensate Drain

The condensate drain outlet is a 3/4" (19.1 mm) threaded female PVC con-

nection located at the bottom of the unit to the left of the evaporator access

panel.

The circulating blower and the condenser fan create a negative pressure

on the condensate drain line that will prevent the condensate from drain-

ing properly without a trap. To combat this negative pressure, a field sup-

plied condensate trap that will allow a standing column of water of at least

2" (50.8mm) MUST be installed. The outlet of the trap must be at least 1"

below the unit drain connection. Install the trap as near to the unit as

possible for proper drainage.

A3/4" (19.1 mm) drain line MUST be installed if required by local codes or if

location of unit requires it. Run the drain line to an open drain or other suit-

able disposal point.

7. Electric Heat Installation General

Information 8. Installing Electric Heat Accessory

General Information

Installation or repairs made by unqualified persons can result

in hazards to you and others. Installation must conform with

local building codes or, in the absence of local codes, with

National Electrical Code ANSI/NFPA 70-1990 or current

edition.

The information contained in this manual is intended for use

by a qualified service technician familiar with safety

procedures, equipped with the proper tools and test

instruments.

Failure to carefully read and follow all instructions in this

manual can result in malfunction, property damage, personal

injury, and/or death.

When an electric heat accessory is installed, two separate field power

supplies MUST be provided - one or more for the electric heat accessory

and one for the unit.

FIGURE 7 The Electric Heat Accessory

Breaker-

Electrical shock hazard.

Shut OFF electric power at unit disconnect and/or service

panel before beginning the following procedures.

Failure to follow this warning can result in property damage,

personal injury, and/or death.

1. Shut OFF electric power at unit disconnect switch or service panel.

2. Remove the blower access panel from unit.

NOTE: Installation of field wiring and conduit for heaters to the

unit prior to installing the heater will simplify wiring of heaters.

3. From inside the blower compartment, remove the six screws on the

heater cover plate and save the screws. Discard the heater cover

plate.

The screws will be used later to mount the electric heat accessory

and its cover.

4. Remove the cardboard wrapper from the heater's elements.

5.Insert the heater into the heater/blower box. Exercise caution to

prevent damage to heater elements.

&Secure heater to heater/blower box with four of the six screws re-

moved in Step 3.

FIGURE 8 Installing The Electric Heat Accessory

10 427 01 1004 01

9. Heater Electrical Wirinq

Electrical shock hazard.

Shut OFF electric power at unit disconnect or service panel

before making any electrical connections.

Unit MUST be grounded before making line voltage connec-

tions. Do NOT fuse ground or neutral conductors.

Failure to follow this warning can result in property damage,

personal injury, and/or death.

NOTE: All electrical work MUST conform with the requirements of local

codes and ordinances and in the United States with National Electrical

Code ANSI/NFPA70-1990 or current edition. Provide line voltage power

supply from a separate protected circuit with a disconnect switch (when

required) located within sight ofthe unit. Supply voltage, amperage, fuse

and disconnect switch sizes MUST conform with all technical specifica-

tions in this manual and on the unit rating plate and local codes.

Wiring MUST be protected from possible mechanical damage and MUST

NOT interfere with removal of access panels, filters, etc.

All exposed wiring or connections MUST be made with weatherproof

cable or wire unless installed in conduit.

All line voltage connections and the ground connection MUST be made

with copper wire.

The power supply wiring MUST have overcurrent protection. This can be

either fuses or circuit breakers. The maximum size for the overcurrent

protection is shown in the column labeled "Max. Fuse or NEC HACR

Breaker (Amps)" in the Electrical Data Table in FIGURE 10 or on the unit

rating plate.

Grounding

Permanently ground the electric heat accessory in accordance with local

codes and ordinances and in the United States with National Electrical

Code ANSI/N FPA70-1990 or current edition. Use a copper conductor of

the appropriate size from the electric heat accessory to the ground lug on

the circuit breaker panel as shown in FIGURE 9.

Adjusting Thermostat Anticipator

Set theheat anticipator of the thermostat to the propervalue. See instruc-

tions provided with the thermostat before making this adjustment.

AM MK07AH B/A .36

AMMK10AH B/A .36

AMMK15AH B/A .36

AM MK20AH B/A .54

Limit Controls

The limit controls are mounted on the face of the heater and are wired into

the supply wires to each element. If there is not enough air flow through

the heater, the limit will open and break the power circuit. The limit will re-

set when the electric accessory cools down.

Time Delay Operation

The heater elements are switched ON and OFF through one or more con-

trois which operate through the low voltage thermostat circuit.

These controls consist of a number of time delays depending on the spe-

cific heater model. An electric heat accessory has 1,2 or 3 of these con-

trois. The first time delay is activated when the thermostat contacts close.

Approximately 1 to 20 seconds later the indoor blower and the first heater

bank are energized. Approximately 70 seconds after the first heater bank

is energized the remaining time delays and heater banks are energized.

Staging

Some electric utilities require staging on electric heaters larger than 6 kilo-

watts. Therefore, the heater elements are turned on in 5 or 10 kW incre-

ments under control of the sequencers.

If staging based on heat loss or demand is required, the use of accessory

outdoor thermostats is recommended. The heat sequencer wiring is de-

signed to be staged by breaking the 24V "Common" Leg (normally brown

or gray). Outdoor thermostats available through your wholesale supplier

allow the control of two or four stages of electrical heat.

Some indoor electronic thermostats may provide for multiple stage of

electric heat. When this type thermostat is used, it may be necessary to

break the 24V"Hot" leg of the sequencer (as fed from the "W' circuit at the

thermostat). This will require field modification of the control wiring and

should only be done by an experienced controls technician/or electrician.

Installing Wiring

1.Shut OFF electric power at unit disconnect or service panel.

2.Install the appropriate field supplied conduit fitting into the heater

knockout located in the rear panel of the unit. The wiring entrance

hole is sized for 1" conduit.

11 427 01 1004 01

TypicalWiringInstallation(BreakerStyleHeaterShown-Pigtailstylealsoavailable)

UnitLineVoltageWires

3.Connect field installed copper ground wire(s) to the ground lug(s) on

the heater mounting plate. On models with more than one circuit, a

separate copper ground wire MUST be connected to a separate

ground lug for each circuit.

4. Route the field supplied line voltage wires for the heater to the line

side of the electric heat accessory's circuit breaker(s) or high voltage

wiring harness. Leave approximately 8" of excess wire so the break-

er or wiring harness may be moved to service. Make line voltage

connections to L3-L6 as appropriate. NOTE: If heaters without

breakers are used, route field wires to inside of unit and attach to

heater wires tagged L3-L6 as appropriate using supplied wire nuts.

6 Connect the red wire with terminal in the heater wire harness to the

loose red wire from the unit sequencer.

7. Connect the white wire from the heater wire harness to the white wire

from the thermostat at the field supplied low volt wire harness in the

control box.

8. Connect the grey and brown wires from the heater wire harness to

the blue wire from the unit 24V common. NOTE: If outdoor thermo-

stats are used for staging electric heat, connect the grey and brown

wires according to the thermostat instructions. See "Staging" in

Electrical Wiring Section of this Manual.

5. Connect the black wire with terminal from the heater wire harness to

the loose black wire at the unit blower.

NOTE: Check FIGURE 11 for heater/speed combinations that are

unacceptable.

After completing installation of the heater, install the breaker rain shield on

the blower access panel according to the following instructions on page

13. If using a pigtail style heater, proceed to Start-Up Procedures for Aux-

iliary Electric Strip Heat on page 14.

connected to an existing system, the ductwork MUST be checked to make

sure it is adequate. Extra runs or larger duct sizes may have to be

installed.

Maximum recommended velocity in trunk ducts is 1000 feet per minute

(5.08m/s). Velocity in branches should not exceed 800 feet per minute

(4.06m/s). Refer to the TechnicalData Label on the unit for unit air volume

requirements and system sizing recommendations.

NOTE: Ductwork sizing affects temperature rise and cooling temperature

differential. Be sure to properly size ductwork to the capacity and airflow

characteristics of your unit. Failure to do so can affect limit controls, com-

pressors, motors, and other components and will lead to premature failure

of components. This will also adversely affect day to day unit perfor-

mance.

Flexible Duct Kits are available from your supplier to effect proper sizing

and installation to Mobile Homes and other standard construction..

Refer to unit rating plate for proper Electric Heat Accessory sizing and see

the Temperature Rise Check section inthe Electric Heat Accessory Instal-

lation Section of this manual.

1. Removeall screwsfrom the cover plateon Blower/ElectricalAccess Panel.

2. Install adhesive backed gasket on Blower/Electrical Access Panel.

3.Install lower frame of rain shield with 4 screws.

Ductwork Insulation

It is recommended that ductwork installed outdoors have a minimum of 2"

(51mm) of fiberglass insulation and be covered by a weatherproof vapor

barrier that is protected against damage. Caulking and flashings, or other

means adequate to provide a permanent weather seal, must be used.

4.Install rain shield hinged cover with 4 screws.

5. Install circuit breaker filler plates (2 each per unused breaker slot.)

It is recommended that ductwork installed in attics or other areas exposed

to outdoor temperatures have a minimum of 2" (51mm) fiberglass insula-

tion and have an indoor type vapor barrier.

6. Re-install Blower/Electrical Access Panel.

NOTE: VERIFY ALL APPROPRIATE SEALS ARE IN PLACE. SEE

FIGURE 12,

Ductwork Connections

The use of flexible, non-combustible connectors between main trunk

ducts and supply and return air plenums is recommended to minimize

vibration transmission.

11. Air Distribution System

For airflow data (blower performance data, blower speed tap settings,

etc.) see the Technical Data Sheet attached to the unit..

Ductwork

NOTE: Connect supply and return air plenums to unit in a manner that will

allow the top of the unit to be removed without removing plenums. Ple-

nums MUST be individually sealed to unit casing. Ducts MUST be termi-

nated inside structure.

Filters

NOTE: The total heat gain of the structu reto be conditioned as expressed

in total Btu/hr should be calculated by manufacturer's method or in accor-

dance with "A.S.H.R.A.E. Guide" or "Manual J - Load Calculations" pub-

lished by the Air Conditioning Contractors of America. The total heat gain

calculated should be equal to or less than the cooling capacity output

based on D.O.E. test procedures, steady state efficiency times input.

Ductwork, supply registers, and return air grilles MUST be designed and

sized to handle the unit's cooling air volume requirements. If the unit is

All return air MUST pass through a field supplied filter before entering the

unit. If used, an electronic air cleaner MUST be installed in the return air

ductwork. Minimum recommended filter areas are listed in FIGURE 13

and are based on a velocity of 300 ft/min (1.2m/s) for disposable filters

and 500 ft/min (2.54m/s) for washable high velocity filters.

CAUTION

Do NOT operate the unit without all filters in place.

12. Start-up Procedures

Electrical shock hazard.

Use extreme care during all of the following checks and pro-

cedures.

Make sure electric power is turned OFF as instructed in ap-

propriate steps.

Failure to follow this warning can result in property damage,

personal injury, and/or death.

Circulating Air Blower

Determining Blower Speed

1.Turn electric power OFF.

2. From the system design, determine the total external static pressure

(ESP) for the supply ducts, return ducts and registers, diffusers,

grilles, dampers, heaters and filters.

3.To your system ESP determined in Step 2, add 0.05 In. W.C. for a

wet coil.

4.From the system design, determine the desired cooling airflow in

cubic feet per minute (CFM).

5. Locate the unit's Blower Performance Data table on the tech data

label for the unit's voltage. (The tech data sheet is attached to the

evaporator access panel on the unit.) From the table, determine the

speed tap required to achieve the desired airflow.

6. See next section, Speed Taps, to set the blower motor speed termi-

nal block (speed taps) to the cooling speed determined in the pre-

vious steps.

Speed Taps

After determining therequired CFM andspeed tapdata fromthe tech data

sheet, follow the steps below to change speeds if necessary.

BE SURE TO CHECK BLOWER MOTOR SPEED DATA ON THE

UNITS TECHNICAL DATA LABEL LOCATED ON THE UNIT.

NOTE: On Heat Pumps Electric heater blower wire must be attached to

the same speed tap required for cooling/heat pump operation. See FIG-

URE 11 notes. The yellow lead MUST always be connected to the speed

tap block at the common quick connect terminal. The terminal is identified

as COM.

Refer to FIGURE 15 and the appropriate unit wiring diagram included in

this manual. Wire the black wire to the required speed tap terminal to

achieve required airflow determined in Step 5.

Cooling, Heating (Heat Pump) and Auxiliary

Electric Strip Heat

NOTE: The cooling, heat pump and strip heat airflows are all on the same

speed tap. The refrigerant system requires the same specific CFM for

proper operation in the cooling and the heat pump mode. For this reason,

cooling and heating airflow must be the same. DO NOT SPLIT OUT INTO

A COOLING SPEED AND HEATING SPEED. If auxiliary electric heat is

installed, the auxiliary electric heat blower speed wire must be connected

to the black wire insulated quick connect terminal.

Check Before Starting

1. Check that the blower motor speed terminal block is set to the prop-

er cooling speed. Refer to the unit wiring diagram and the various

airflow tables in this manual.

2. Check to see that clean, properly sized field supplied air filters are

installed in the return air duct.

3. Inspect the inside of the unit to be sure that all wires are in place and

all tools, etc. are removed.

4. Replace all service access panels.

Check the unit's operation as outlined in the following instructions. If any

unusual sparking, odors or noises are encountered, shut OFF electric

power immediately. Recheck for wiring errors, or obstructions in or near

blower motors.

a. Contactor contacts opening.

b. Compressor - OFF

c. Condenser fan motor - OFF

d. Circulating blower - OFF (after delay)

6.Turn electric power OFF

Auxiliary Heating

NOTE: Repeat circulating air blower procedure above if Auxiliary Electric

Heat is being installed after unit has been installed and checked out.

Temperature Rise Check

Temperature rise is the difference between the supply and return air tem-

peratures. The temperature rise should be -+2°F (1.1°C) of the tempera-

ture rise shown in FIGURE 11 .

NOTE: The temperature rise can be adjusted by changing the heating

speed tap at the unit's blower terminal block. Refer to the unit's Installation

Instructions for airflow information.

Atemperature rise greater than 60°F (33.3°C) is not recommended. (This

applies to electric heat only).

1.To check the temperature rise through the unit, place thermometers

in the supply and return air ducts as close to the unit as possible.

2. Open ALL registers and duct dampers.

3.Set thermostat Heat-Cool selector to HEAT.

Electrical shock hazard.

Turn OFF electric power supply at disconnect switch or ser-

vice panel before removing any access or service panel from

unit.

Failure to follow this warning can result in property damage,

personal injury, and/or death.

To adjust defrost interval:

1.Turn off all power to Heat Pump.

2. Remove control box cover.

3. Locate electronic defrost control board.

4.The Defrost Control Board has ajumper plug that can be set at 30, 60,

90 or TEST. Remove the plug and insert on the appropriate 2 pins

indicated by ) on the board.

13. Sequence of Operation

NOTE: If power to the unit has been interrupted, there will be a 3 minute

delay before the compressor starts.

Cooling Mode: Energized (R,G,Y, O) De-energized (N/A)

(a) When high and low voltage have been applied to unit

for more than 3 minutes:

(1)On a call for cooling ......... :

The compressor and condenser fan will energize. The evaporator

blower motor will have a delay on and will energize after 30 seconds.

17 427 01 1004 01

(2)When the cooling setpoint has been satisfied ......... :

The compressor and condenser fan will de-energize immediately.

The evaporator blower motor will have a delay off and will de-ener-

gize after 30 seconds.

Heat Mode (Heat Pump Only): Energized (R,G,Y)

De-energized (O)

(a) When high and low voltage have been applied to unit

for more than 3 minutes:

(1) On a call for heating ......... :

The compressor and condenser fan will energize (there will be a 3

minute delay on 4Ton model with anti-cycle timer). The evapora-

tor blower motor will have a delay on and will energize after 30 se-

conds. The delay on for the compressor and the condenser fan can

be by-passed by jumpering the test pins on the defrost control

board.

(2) When the heating setpoint has been satisfied ......... :

The compressor and condenser fan will de-energize immediately.

The evaporator blower motor will have a delay off and will de-ener-

gize after 30 seconds.

Defrost Mode:Energized (R,G,Y) De-energized (O) Defrost

Sensor Closed

(1) On a call for defrost .........

When the defrost sensor c!oses in the heating mode,there is a 30,

60 or 90 minute delay before the defrost mode begins. This delay

is selected by the position of a jumper on the defrost board

In normal defrost mode, the following sequence will occur after the

set delay:

1. Condenserfan off.

2. Reversing valve energized to cooling and auxiliary electric

heat ("W" circuit) is energized.

3. After defrost sensor opens or a maximum of 10 minutes; the

condenser fan is energized immediately. After a 10-12 second

delay the reversing valve is then de-energized to the heat mode.

Electric strip heat is also de-energized except as required by ther-

mostat.

To check out the defrost mode, place jumper across the two tabs

marked "DF". This simulates the defrost sensor closing. The delay

can be by- passed by jum pering the test pins on the defrost control

board (this reduces the delay from 30 minutes to 7 seconds, from

60 minutes to 14 seconds and from 90 minutes to 21 seconds). In

the defrost mode the reversing valve will energize and the con-

denser fan will de-energize.

NOTE: If the jumper on the defrost delay selection is left in the "TEST"

mode, the board will default to 90 min. delay until power is off.

(2) When defrost has been completed .........

This condition will be maintained until the defrost sensor opens or

until the defrost mode operates for 10 minutes (or 2 seconds if test

pins are jumpered), whichever comes first.

Adding Accessories

Low/High Pressure Controls

This unit is equipped with extra !ow and high pressure ports located inside

the unit panel where the external high and low pressure ports are installed.

This allows for installation of high and low pressure controls or low ambi-

ent controls.

14. Operation

Scroll Anti-Cycle Timer (Where Applicable)

Single phase units with scroll compressors may be equipped with an anti-

cycle device which delays the start of the compressor in the event of a

power interruption. This equalizes pressure throughout the system and

prevents possible reverse rotation ofthe scroll compressor. Later produc-

tion scroll compressors are equipped with an anti-reverse device to pre-

vent the compressor from running backwards, so an anti-cycle timer is not

needed on these models.

CAUTION

Do NOT operate unit on cooling when the outdoor temperature is be-

low 60°F. This is necessary to prevent possible damage to the com-

pressor.

Loss of Charge Pressure Switch

Scroll compressor bearing units are equipped with a low pressure switch

on the liquid line (high side) which has been installed to prevent system

damage due to a loss of charge. The switch will open and de- energize the

contactor if the high side pressure drops below the set point of the switch.
