Initial Unit Start-up

Start-up with the system controls is included below: Note: Air Handlers should not be operated in the construction phase of dry walling. The air-to-refrigerant coil will foul, and the warranty will be void.

1.Set the system control to the desired mode of operation.

2.Set the control switch to fans and circulation pumps. The compressor should NOT run.

3.Reduce the temperature control setting until the compressor, reversing valve, solenoid valve, and loop pump are energized. Adjust water flow utilizing pressure/temperature plugs and comparing to tables contained in specification sheet data. Water leaving the heat exchanger should be warmer than the entering water temperature (approximately 9°F-12°F); compressor amps should be within data plate ratings; the suction line should be cool with no frost observed in the refrigerant circuit.

4.Check the cooling refrigerant pressures against values in Table OP1. (Page 22).

5.Turn the system control switch to the OFF position. Unit should stop running and the reversing valve should de-ener- gize.

6.Leave unit off for approximately FIVE minutes to allow for pressure equalization.

7.Turn the thermostat to the lowest setting.

8.Set the thermostat system switch to the opposite mode of operation.

9.Adjust the temperature setting upward until the unit is energized. A water temperature decrease of approximately 5°F- 9°F leaving the heat exchanger should be noted. The compressor operation should be smooth with no frost observed in the refrigeration circuit.

10.Check the heating refrigerant pressures against values in Table OP1. (Page 22)

11.Set the system control to maintain the desired space temperature.

12.Instruct the owner on system operation.
