CONTROL

PIN'( DOOR

2, Remove the front panel (contained in a protective

plastic bag) from chassis. Remove the bag and

dispose of it properly. Install the control door as

per instructions.

To install,follow these steps:

• Insert the control door into the front panel from the

back side of panel.

From the frontofthe panel, slide the right control

door pin into the hole on right side of the front panel.

Slide the left door pin into the slot on the left of the

front panel opening and snap it into place.

CAUTION

To avoid breaking the door or hinge pins, do not

apply excessive force when installing.

Com#reseor

3. Remove the two chassis shipping brackets from the

corner of the shipping pallet.

Wall Sleeve

.Locate the four #10 x 1" chassis mount-

ing screws and tighten them into the clips

in the wall sleeve flange, (two per side).

Chassis Flange

If a Remote Thermostat is to be installed, proceed to Appendix A, Step 6.

If Central Desk Control is to be installed, proceed to Appendix B, Step 6.

rl'T

Install the front panel by placing the top of the

panel onto the brackets at the top of the chas-

sis. Rotate the bottom into place while locating

the service cord (or conduit) in a notch at the

bottom or sides of the front panel.

Secure the panel to the chassis with two #10 x

3/4" screws (provided). Attach the bottom

return air louver to the front panel, the louver

snaps into place. The louver can be secured in

place with two #10 x 3/4" screws, provided

(optional).

A notch MUST be made in the front panel side

where the cord exits the unit. It is the responsibility

ofthe installer to create an exit notch. See diagram

(right) for suggested opening size and placement.

Plug the cord (if applicable) into the appropriate

receptacle. Extra cord may be coiled inside the

front panel behind the return air louver. Restore

power to the unit.

Temperature Limiting Thermostat

1. Set thermostat knob to center of dial.

2. Remove four screws holding control panel. Pult up on

thermostat knob and remove.

3. Locate the two temperature limiting screws.These screws

are factory installed for a maximum temperature range of

60-90 ° E Each hole in dial plate represents approximately

a 4° change from the adjacent hole.

4. To adjust temperature range, move temperature limiting

screws to desired location.

5. Replace knob when desired range has been set.

6. Replace control panel.

EXAMPLE: To set a maximum temperature range of approxi-

mately 64 to 86° F,move screws to locations shown in diagram

at right.

Heating Control

NOTE: Heat pump models only. Heat pump equipped models use

backup electric resistance heating coils. At extremely low outdoor

ambient temperatures, the heat pump is automatically disabled and the

unit operates solely on electric resistance heat.

The heating control islocated behind the front panel at the control box

bottom and is accessible through the return air louver opening. Its

function is to allow you to set the temperature range in which the heat

pump operates. This control switches the unit heat operation between

heat pump and electric resistance heat based on the outdoor ambient

temperature. These change over temperatures are based on the

settings of this control. In most cases, the factory setting (at approxi-

mately the one o'clock position) is adequate. If you wish to change the

In the event of a compressor malfunction, turn the screw to the extreme counterclockwise emergency heat position. The

heater will then cycle using electric resistance heat only. Note that in the emergency heat position, the compressor is locked

out, disabling both heat pump and cooling operations. CALL A SERVICE PERSON.

The fan cycle switch islocated behind the front panel at the bottom of the

designed to operate the fan either continuously or intermittently with the

compressor or heating elements. When the switch is in the CONTINU-

OUS position, the fan will run continuously when the power switch is on.

With the fan cycle switch in the CYCLE position, the fan will run only when

the compressor or heating elements cycle on.

recommended that this switch be set in the continuous position. I

Air Outlet Louver

\\\

The air outlet louver can be redirected to blow air either straight

up or at an angle into the room. To change the airflow direction,

remove the front panel, and the two screws on either side of the

louver. Reverse ends of louver and refasten.

Startup Checklist INOTE: Units are to be installed and

checked for proper function by qualified

service personnel ONLY.

Check the following:

_/ Unit is installed in compliance with all codes

and ordinances.

_/ Circuit breakers and wire sizes are correct.

_/ Filter is clean and in place.

_/ All panels are in place.

_/ Condenser air inlet and outlet free of obstruc-

tions.

_/ Operate unit 20 minutes.

_/ Controls operation OK.

_/ Owner or operator instructed on control opera-

tion and routine maintenance.

_/ Name and phone number of service company

attached to unit or noted in telephone directory.

_/ Condensate drain adequate.

Work area clean and free of debris. _/ Electrical cord is stored properly.

11 Routine Maintenance

NOTE: Fan motor and all bearings are i

permanently sealed and do not require oiling. I

,IJ Keep air intake filter clean. A dirty filter reduces the efficiency of the system and can cause erratic performance of

controls. It can also result in damage to the heating element and compressor. The unit is provided with a washable

filter that can be cleaned with soap and water. Inspect and clean the filter at least once a month or more often as

conditions dictate. Replace as necessary with a factory approved filter. To replace, slide it up and out through the

front cover immediately in front of the discharge grille opening.

,IJ Do NOT block off outside air flow. Efficient operation of the unit depends on free circulation of air over the indoor and

outdoor coils. Paper, leaves and other debris can reduce efficiency and cause serious damage to the compressor.

,IJ Coils should be inspected periodically for buildup of lint, dirt, leaves, other debris and bent fins. Clean coils with a soft

brush and compressed air or vacuum. Do NOT use sharp objects to clean coils.

,IJ Do NOT operate unit with front panel removed or without filter.

,IJ Ensure that objects such as drapes, furniture, or plants are not blocking free air flow of unit.

,IJ Keep doors and windows closed. Leaving them open will increase the work load on the unit and will result in higher

operating cost and excessive condensate.

,IJ Do NOT operate the unit during construction. Construction dust can clog filter and cause permanent damage to

other components.

,IJ Apply silicon based lubricant to the belt drive system as needed. DO NOT USE ANY SOLVENT BASED LUBRICANTS

SUCH AS WD-40 TM.

Apply silicon-based

lubricant to belt located

inside access door.
