INSTALLATION

A. Unit Check-Out Procedure - IMPORTANT

1.Filter(s) must be clean and in place as to filter all air passing over indoor coil,

2.Set thermostat to "OFF" position.

3.Check that correct size fuses are installed for unit.

4.All panels must be in place.

5.Turn on main power to unit.

B.Heating Check

1.Set fan switch to "AUTO".

2.Set thermostat lever to lowest temperatuf'e.

3.Set thermostat switch to "HEAT" position (if indoor ambient temperature is near or colder than thermostat setting, heat pump will start immediately).

4.Slowly adjust thermostat to warmer temperature until first stage heat is activated (com- pressor will start).

5.If'possible, check outdoor fan to make sure it'srotating (this is especially important If heat pump has been installed for sometime and not running in the winter such that the outdoor fan plenum could be clogged with snow or ice build-up).

6.Check indoor air outlet to verify indoor fan is blowing air and getting warmer.

7.Adjust thermostat lever to at least 5"F warmer temperature So that second stage heat will activate.

8.Check indoor air outlet for increased heating (higher temperature).

C.Cooling Check

1.Set thermostat switch, to "OFF" position for minimum of 5 minutes to allow heat pump pressures to equalize.

2.Set thermostat lever to lowest temperature for cooling

3.Set thermostat switch to "COOl." position (compressor should start unless indoor ambient is near or colder than thermostat setting).

D.Blower Operation

1.Set thermostat switch to "OFF" position.

2.Set fan switch to "ON". Indoor fan only will operate.

3.Return fan switch to "AUTO". Indoor fan will stop.
