7.After reassembly of all parts is complete and all wires are reconnected, open the main manual gas shutoff valve; check for and correct any gas leaks. Turn electrical power on, initiate a call for heat, and check for proper burner operation.

8.Install burner access panel.

Heat Anticipator

The heat anticipator setting is 0.75 amp. It is important that the anticipator setpoint be correct. Too high of a setting will result in longer heat cycles and a greater temperature swing in the conditioned space. Reducing the value below the correct setpoint will give shorter “ON” cycles and may result in the lowering of the temperature within the

conditioned space.

OPERATION

Cooling System

The cooling system is a complete factory package utilizing an air-cooled condenser and is factory-charged with HFC-R-410A. The compressor is hermetically sealed and base mounted with rubber-insulated hold-down bolts.

Unit compressors have internal protection. In the event there is an abnormal rise in the temperature of the compressor, the protector will open and cause the compressor to stop.

Preliminary Operation Cooling

After the initial installation, the compressor should be given three false starts (energized just long enough to make a few revolutions), with 5 – 7 minutes between each start, before being put into full-time service.

Cooling Sequence of Operation

When the thermostat calls for cooling, R is closed to G and Y (see the wiring diagram found on page 13). This action completes the low voltage control circuit, energizing the compressor, condenser fan motor, and blower motor.

Blower Delay – Cooling

The circulating air blower is controlled by a timing circuit in the integrated blower/ignition control. Timings are not adjustable. Blower “ON” delay is 5 seconds after the compressor starts and blower “OFF” timing is 90 seconds after the cooling system shuts down.

System Performance

For maximum performance of the cooling system, operating temperatures and pressure should be checked. Superheat should be determined at Standard ARI test conditions of 82°F outdoor and 80°F indoor dry bulb/67°F wet bulb. If superheat measured deviates from values found in Table 3, refrigerant charge should be adjusted accordingly for maximum performance.

Heating System

With the proper thermostat and sub-base, continuous blower operation is possible by closing the R to G circuit. Cooling blower delay is also functional in this mode.

Heating Sequence of Operation

The following sequence describes the operation of the gas heat section.

1.When the thermostat calls for heat, the draft motor is energized by the 24-volt relay in the blower ignition control which closes the 240V contact to the draft motor.

2.When the speed of the draft motor reaches proper RPM, the pressure switch closes to power the ignition control.

3.When PSW on ignition control is energized, a pre-purge time is initiated (30 seconds nominal).

4.When pre-purge has expired, the gas valve is energized for direct ignition. The ignition control energizes the main gas valve and spark electrode for a period of 10 seconds.

5.Thirty seconds nominal after the initial trial for ignition, the circulation air blower will start. If the flame sensor
