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

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.

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.

_/ 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
I
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.
