Operation

Starting the unit in cooling mode

Before start-up, ensure that all power cables are tightened.

Verify that the unit airflow rate is adjusted according to the information provided in the "Supply fan adjustment" section of this manual.

To start the unit in cooling mode:

Place the zone sensor system switch in the "COOL" position.

Position the cooling setpoint approximately 10° below room temperature and place the fan switch in the "AUTO" or "ON" position.

Turn on unit main power supply.

The condenser fan motor, compressor and supply fan motor should operate automatically.

There will be a delay of up to

5 minutes before the unit starts in cooling mode.

Operating pressures

After the unit has operated in cooling mode for a short period of time, install pressure gauges on the gauge ports of the discharge and suction line valves.

Note: To bypass time delays and verify the operation of this unit from the roof, use the "Test procedure" section in this manual. Check the suction and discharge pressures.

Note: Always route refrigerant hoses through the port hole provided and ensure that the compressor access panel is in place.

Cooling shutdown

To exit the test mode, disconnect unit power for 3-5 seconds and reapply. When running the unit using the zone sensor as the control, position the selector switch to "OFF".

There may be a delay of up to

3 minutes before compressors shut down and an additional one minute before the fan shuts down in this setting.

Do not de-energize main power disconnect except when unit is to be serviced. Power is required to keep the compressor crankcase warm and boil off refrigerant in the oil (except on units with Scroll compressors).

Final installation checklist

Are all power cables tightened?

Check torque of power cables contact !

Is the condenser fan and indoor blower operating correctly, i.e. correct rotation and without undue noise?

Are the compressors operating correctly and has the system been checked for leaks?

Have the voltage and running currents been checked to determine if they are within limits?

Have the air discharge grilles been adjusted to balance the system?

Has the ductwork been checked for air leaks and any condensation?

Has the air temperature rise been checked?

Has the indoor airflow been checked and adjusted if necessary?

Has the unit been checked for tubing and sheet metal rattles or any unusual noises?

Are all covers and panels in place and properly fastened?
