Installation Checklist Electric shock hazard. Turn off electric power before service or installaSor Read these instructions carefully and completely before attempting installation. Unit should be installed by qualified service personnel ONLY. All electrical connections and circuits are installed in compliance with and conform to the National Electrical Code and local codes which have jurisdiction. Failure to do so can result in property damage, personal injury and/or death.
Electrical Rating Tables All 230/208 volt units are equipped with power cords. See Appendix C on page 17 for wiring instructions on 265V units. Table 2 I NOTE: Wire sizes are per NEC. Check local codes Useoverseas Copper Conductors for applications. ONLY.
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. 2, Suffocation hazard. Keep bag away from babies and children. Do NOT use in cribs, beds or playpens, Destroy immediately after opening. This bag is NOT a toy! To install, follow these steps: Failure to do so can result in personal injury and/or death. • PIN'( Insert the control door into the front panel from the back side of panel.
. Install the front panel by placing the top of the panel onto the brackets at the top of the chassis. Rotate the bottom into place while locating the service cord (or conduit) in a notch at the bottom or sides of the front panel. ® Place on brackets here 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). 7. .
Unit Operation Pushbutton Rotate the temperature dial in small increments in the warmer or cooler direction. Moving the dial more than 1/4" at a time may overcompensate and result in an extreme hot or cold situation. Control Operation Operates unit on cooling - cooling will not begin if room temperature is below 60 E Operates unit on heating. Some models do not provide this selection. Circulates air within the room. No heating or cooling functions. Shuts system down.
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. OMP6" 04'Z_ O The heating control is located 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.
Air Outlet Louver I I I I I 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. I \ \ \ I NOTE: Startup Checklist Check _/ Units are to be installed and checked for proper function by qualified service personnel ONLY.
11 Routine Maintenance I NOTE: Fan motor and all bearings are permanently sealed and do not require oiling. i 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.
Appendix Installation 1. Remote Thermostat Conditioners A: Selection, Wiring & of Remote Thermostat Selection & Wiring Guidelines for Packaged Terminal Air Follow the instructions and recommendations of the thermostat manufacturer for installation and wiring. We do not recommend a conventional heat pump thermostat with emergency electric heat selection for our heat pump units. Our units make an automatic decision about turning on emergency heat if the heating demand cannot be met by the heat pump.
B. Auto Changeover Thermostat A single stage thermostat with dual stages of heating and auto changeover is needed. The recommended Thermostat/ Subbase combination is the Honeywell T-874C/Q 674E.

Appendix . A (Continued) Install the front panel by placing the top of the panel onto the brackets at the top of the chassis. Rotate the bottom into place while locating the service cord (or conduit) in the notch at the bottom or sides of the front panel. ® ® g. 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).
Appendix Remote A (Continued) Thermostat 208V Operation CAUTION CONNECTION DIAGRAM If the supply voltage is 208V, the low voltage transformer IVlUST be wired for 208V operation. Failure to do so will result in lower control voltages to the unit and can damage low voltage components. The simplified connection diagram at left shows the factory configured wiring set for 240V operation.
Appendix B: Installation Central Desk Control of Follow steps 1 through 5 (pages 4 and 5), then: 6. Attach two wires from the central desk control to the terminal board on the right side of the control box.The central desk control must provide 24 volts AC to this terminal board in order to switch the unit to the unoc- ® 7. cupied mode. When the 24 volts AC is turned off, the unit returns to the occupied mode. If filter is not in place, locate and place as shown. m (_ 8. g.
Appendix B (Continued) NOTE: If the unit is mounted flush to the floor, the service cord MUST be rerouted through the side of the front panel closest to the receptacle. A notch MUST be made in the front panel side where the cord exits the unit. It is the responsibility of the installer to create an exit notch. See diagram for suggested opening size and placement. 10.
