INTRODUCTION

The MF modular blower cabinet uses a 208/230V PSC blower

motor, with an electronic fan control board. The MF may be used for

cooling or heat pump applications either with or without electric

heat. Installations without electric heat require a NO HEAT KIT

(EHIA00KN10). The cabinet can be installed in an upflow,

downflow or horizontal position. Refer to Figure 3 and 4.

LOCATION

Select the best position which suits the installation site conditions.

The location should provide adequate structural support, space in

the front of the unit for service access, clearance for return air and

supply duct connections, space for refrigerant piping connections

and condensate drain line connections. If heaters are being

installed, make sure adequate clearance is maintained from supply

ductwork, See Clearances and Warning in Figure 1.

If the unit is located in an area of high humidity, nuisance sweating

of casing may occur. On these installations a wrap of 2" (51mm)

fiberglass insulation with a vapor barrier should be used.

HEATER PACKAGES

Factory approved, field installed, UL listed heater packages are

available from the equipment supplier. See unit rating plate for a list

of factory approved heaters (electric heat accessory models EHIA

only). Heaters that are not factory approved could cause damage

which would not be covered under the equipment warranty.

CUTHAZARD

Failure to follow this caution may result in personal in-

jury.

Sheet metal parts may have sharp edges or burrs. Use

care and wear appropriate protective clothing and

gloves when handling parts.

INSTALLATIONS

The unit is ready to install in any position without modifications.

Refer to the coil instructions for information on drain pan

configurations etc. Make sure coil is set up properly for desired

position of blower cabinet.

Coil must be secured to blower cabinet with the three tabs that are

part of the blower cabinet base. Bend the tabs out from the bottom

so they fit over the coil cabinet.

Position coil cabinet in relation to the blower so they will be correct

for desired application.

2Specifications are subject to change without notice. 442 01 2206 01

For upflow and horizontal applications apply foam seal strip around

top of coil cabinet. For downflow application apply foam seal strip

around bottom of coil cabinet. Set blower on top of coil cabinet so

they are flush. Secure cabinets together using the three tabs on the

bottom of the cabinet. Bend the tab out from the bottom so it fits over

the coil cabinet. If no pilot holes are present, drill a hole as required

for a screw.

Attach Coil to Blower Cabinet

DOWNFLOW INSTALLATIONS

Refer to instructions with Subbase Kit.

NON-DUCTED RETURN AIR CLOSET

INSTALLATION

The cabinet can be installed in a closet with a false bottom to form a

return air plenum, or mounted on an open platform inside the closet.

Platform should be high enough to provide a free (open) area for

adequate return airflow into the bottom of the cabinet. The open

area can be on the front side or a combination of front and sides,

providing there is clearance on the sides between cabinet and

closet. Refer to ACCA Manual D for sizing and free area

recommendations.

NOTE: Local codes may limit application of systems without a

ducted return to single story dwellings.

HORIZONTAL LEFT AND RIGHT

INSTALLATIONS

The modular blower cabinets can be installed in either downflow,

horizontal left, or horizontal right applications. When a coil cabinet

is applied, refer to the coil installation manual for proper drain pan

and airflow requirements. They must have the drain pan

repositioned for right hand airflow. Refer to coil installation manual.

PROPERTY DAMAGE HAZARD

Failure to follow this caution may result in property

damage.

Afield fabricated auxiliary drain pan, with a separate

drain is REQUIRED for all installations over a finished

living space or in any area that may be damaged by

overflow from a restricted main drain pan. In some lo-

calities, local codes require an auxiliary drain pan for

ANY horizontal installation.

lect a location where drill and fasteners will not con-

tact electrical refrigeration components.

Figure 6 JFan Control Board

Iw_I

All electrical work MUST conform with the requirements of local

codes and ordinances and the National Electrical Code NFPA 70

current edition.

The low voltage transformer and the fan control are standard on all

models and are prewired at the factory. Line voltage connections

are made to the heater accessory or the lugs on the No Heat Kit.

OVERCURRENT PROTECTION

The power supply wiring to the unit MUST be provided with

overcurrent protection. Governing codes may require this to be

fuses ONLY or circuit breakers.

For blower cabinets without heaters, a 15 amp circuit may be used.

Before proceeding with electrical connections, make certain that

supply voltage, frequency, phase, and circuit ampacity are as

specified on the unit rating plate. See unit wiring label for proper

field high and low voltage wiring. Make all electrical connections in

accordance with the NEC and any local codes or ordinances that

may apply. Use copper wire only. The unit must have a separate

branch electric circuit with a field-supplied disconnect switch

located within sight from and readily accessible from the unit.

NOTE: When a pull-out type disconnect is removed from the unit,

only the Load side of the circuit is de-energized. The Line side

remains live until the main (remote) disconnect is turned off.

ELECTRICAL SHOCK or UNIT DAMAGE HAZARD

Failure to follow this warning could result in person-

al injury, death, and/or property damage.

Turn OFF electric power at fuse box or service panel

before making any electrical connections and en-

sure a proper ground connection is made before

connecting line voltage.

ELECTRICALSHOCK HAZARD

Failure to follow this warning could result in person-

al injury or death.

Turn off the main (remote) disconnect device before

working on incoming (field) wiring. Incoming (field)

wiring on the line side of the disconnect found in

the modular blower unit remains live, even when the

pull-out is removed. Service and maintenance to

incoming (field) wiring cannot be performed until

the main disconnect switch (remote to the unit) is

turned off.

MF units installed without electric heat require the use of a

factory-authorized No Heat Kit (accessory part number

EHIA00KN10). This kit provides the electrical connections

necessary to supply the unit with 208/230V power when electric

heat is not present.

For units without electric heat:

1. Locate adapter and filler plates with screws inside

package. If necessary, adjust plates to allow for installation

of No Heat Kit required inside cabinet. Refer to Figure 7.

2. Secure No Heat Kit accessory with four (4) screws.

3. Connect the 9-pin plug from No Heat Kit wiring into the

receptacle that attaches to fan control board.

4. Connect ground wire to unit ground lug.

5. Connect 208/230V power leads from field disconnect to

terminal block assembly on No Heat Kit.

For units with electric heat, see Electric Heater Installation

Instructions and blower airflow requirements.

NOTE: Transformer is factory-wired for 230V operation. For 208V

applications the transformer must be rewired to the 208V tap. Refer

to unit wiring label.

GROUNDING CONNECTION

Use a copper conductor(s) from the ground lug on the No Heat Kit

or ground lugs on the electric heater to a grounded connection in the

electric service panel or a properly installed grounding rod.

LOW VOLTAGE CONTROL CONNECTIONS

Wire low-voltage in accordance with wiring label on the blower

(also refer to Figures 8- 12. Use 18 AWG color-coded, insulated

(35°C minimum) wire to make the low-voltage connections

between: thermostat, indoor equipment, and outdoor equipment. If

thermostat is located more than 100 feet (31m) from the unit (as

measured along the tow voltage wire), use 16 AWG color-coded,

insulated (35°C minimum) wire. All wiring must be NEC Class 1 and

must be separated from incoming power leads. Refer to outdoor

unit wiring instructions for additional wiring recommendations.

Field supplied low-voltage wiring should be field connected inside

control splice box area (secure with wire nuts), and strain relief

bushing or rubber grommet to seal cabinet opening.

AIR FLOW CHECK

For proper system operation, the air flow through the indoor coil

should be between 350 and 450 cfm per ton of cooling capacity. The

air flow through the unit can be determined by measuring the

external static pressure to the unit and selecting the motor speed

tap that will most closely provide the required air flow.

1. Set up to measure external static pressure at the supply and

return duct connections. Refer to Figure 13.

2. Drill holes in the ducts for pressure taps, pilot tubes, or other

accurate pressure sensing devices.

3. Connect these taps to a level inclined manometer or draft

gauge.

4. Ensure the coil and filter are clean, and all the registers are

open.

5. Determine the external static pressure with the blower

operating.

6. Refer to the Air Flow Data, Table 4, to find the speed setting

that will most closely provide the required air flow for the

system.

7. Refer to Motor Speeds and Airflow in these instructions if the

speed is to be changed.

8. Recheck the external static pressure with the new setting,

and confirm speed switch selection.

TEMPERATURE RISE CHECK

Temperature rise is the difference between the supply and return air

temperatures.

NOTE: The temperature rise can be adjusted by changing the heat-

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

Installation Instructions for airflow information.

A temperature rise greater than 60°F (33.3°C) is not recom-

mended.

1. To check the temperature rise through the unit, place ther-

mometers in the supply and return air ducts as close to the

unit as possible,avoiding direct radiant heat from the heater

elements.

2. Open ALL registers and duct dampers.

3. Set thermostat Heat-Cool selector to HEAT.

4. Set the thermostat temperature setting as high as it will go.

5. Turn electric power ON.

6. Operate unit AT LEAST 5 minutes, then check temperature

rise.

NOTE: The maximum outlet air temperature for all models is 200°F

(93.3°C).

7. Set thermostat to normal temperature setting.

8. Be sure to seal all holes in ducts if any were created during

this process.

SEQUENCE OF OPERATION

A. CONTINUOUSFAN

Thermostat closes R to G. G energizes fan relay on FAN

CONTROL BOARD which completes the high voltage circuit to in-

door blower motor. When G is de-energized, there is a built in 90

second blower-off time delay relay (TDR). To disable the TDR fea-

ture, snip the jumper wire JWl.

B. COOLING MODE

Air Conditioner Only:

Thermostat energizes R to G and Y. G energizes fan relay on fan

control board which completes high-voltage circuit to indoor blower

motor. Y energizes the 24 tow-voltage contactor in condensing

unit. When call is satisfied, Y drops out and there is a 90 second

blower TDR before fan relay opens.

Heat Pump:

Same as above - except thermostat will also energize O for revers-

ing valve operation in cooling mode. O will typically remain ener-

gized by the thermostat (after cooling call is satisfied), or until the

mode is changed to heating.

C. HEAT PUMP

Cooling Mode:

Thermostat energizes R to G, Y and O. G energizes indoor an relay

on fan control board which completes high-voltage circuit to indoor

blower motor. Y energizes the outdoor 24V low-voltage circuit in

heat pump to energize compressor. O energizes reversing valve in

cooling mode and typically remains energized until the mode is

changed to heating. When thermostat cooling call is satisfied. Y

drops out. O remains energized, and there is a 90 second TDR be-

fore indoor fan relay opens.

D. HEAT PUMP HEATING WITH AUXILIARY

ELECTRIC HEAT

Cooling Mode:

Same operation as above in Heat Pump Cooling Mode.

Heating Mode:

Same operation as above in Heat Pump Heating Mode with the ad-

dition of W. Thermostat energizes R to G, Y, and W. W energizes

electric heat relay(s) which completes circuit to heater element(s).

When W is de-energized, electric heat relay(s) open, turning off

heater elements. The White wire in pigtail connects W2, W3, and

E together. This maybe separated for heater staging when avail-

able, see electric heat kit for more information.

through N.C. (normally closed) contacts on fan relay. When W is

de-energized, electric heat relay(s) opens.

CARE AND MAINTENANCE

The system should be regularly inspected by a qualified service

technician. Consult the servicing dealer for recommended fre-

quency. Between visits, the only consumer service recommended

or required is air filter maintenance and condensate drain opera-

tion.

AIR FILTER

Inspect air filters at least monthly and replace or clean as required.

Disposable type filters should be replaced. Reusable type filters

may be cleaned by soaking in mild detergent and rinsing with cold

water. The frequency of cleaning depends upon the hours of opera-

tion and the local atmospheric conditions. Install filters with the ar-

rows on the side pointing in the direction of air flow. Clean filters

keep unit efficiency high.

LUBRICATION

The bearings of the blower motor are permanently lubricated.

CONDENSATE DRAINS

E. ELECTRIC HEAT OR EMERGENCY HEAT

MODE

Thermostat closes R to W. W energizes electric heat relay(s) which

completes circuit to heater elements(s). Blower motor is energized

During the cooling season check the condensate drain lines to be

sure that condensate is flowing from the primary drain but not from

the secondary drain. If condensate ever flows from the secondary

drain, the unit should be promptly shut off and the condensate pan

and drains cleaned to insure a free flowing primary drain.
