1. 

Remove adjacent ceiling tile to access condensate 

pump cover panel.

2. 

Insert squeeze water bottle nozzle through opening in 

condensate pump access panel and fi ll drain pan. See 

 Figure 36 . 

3. 

Adding water activates fl oat switch and pump. 

Water must fl ow regularly when condensate pump is 

energized. If water does not, check pipe slope or see if 

there are any pipe restrictions. 

4. 

Verify all covers, panels and fi lters are in place and 

discharge louvers are correctly positioned.

NOTICE

Unit is equipped with safety switch. Pump is 

activated when condensate reaches critical level. 

Safety switch de-energizes compressor if water level 

becomes too high.

Check Cooling Operation

Cooling-only systems — Turn system power on and turn 

down system setpoint to activate compressor.

Check Heat Pump Operation

1. 

Heat pump systems — Turn system setpoint up to 

activate heat pump (compressor) operation.

2. 

Place system controls into heating mode, with setpoint 

1°F above room temperature; or meeting requirements 

for 1st stage heating operation. Verify compressor 

start, noise, vibration, and overall system operation.

3. 

Change setpoint until 2nd stage of heat is called (>2°F 

(1°C) above ambient temperature).

Two stage heating requires optional electric heat.

Operation

INITIAL START-UP — CAHV UNITS

 WARNING

Electrical shock hazard. Turn off power to indoor and 

outdoor units before proceeding. Failure to follow 

these instructions could result in death or serious 

injury.
