Unit Startup Procedures

WARNING

Hazardous voltage! Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

1.Check all electrical connections for tightness.

2.Be sure all unit accessories are properly set and installed.

3.Inspect all ductwork and duct connections.

4.Check for proper belt tension.

5.Check fan drive sheaves, pulleys, and bearings.

Unit Startup Checklist

1.Set thermostat to Off position

2.Engage power supply by closing power disconnect

3.Switch thermostat to fan position and adjust temperature setting below room temperature. Evaporator fan should start.

4.Check evaporator section for proper operation

5.Switch thermostat to cool position and adjust temperature setting to below room temperature. The evaporator fan, condenser fan(s), and compressor(s) should start.

Note: These units are equipped with high efficiency scroll compressors. Check for proper scroll rotation prior to operating this unit.

WARNING

Rotating Components!

During installation, testing, servicing and troubleshooting of this product it may be necessary to measure the speed of rotating components. Have a qualified or licensed service individual who has been properly trained in handling exposed rotating components, perform these tasks. Failure to follow all safety precautions when exposed to rotating components could result in death or serious injury.

6.Check condenser fan for proper rotation. If fan rotation is incorrect, switch thermostat to Off position and disconnect power. Reverse two phase leads at disconnect and return back to Step 1 of startup.

7.Allow unit to run until all system temperatures and pressures stabilize.

8.Check systems for proper operation and performance. Observe unit in operation and check for unusual noise, vibration, belt and fan clearances.
