TEST RUN
TEST RUN INSTRUCTIONS
You should perform the test run for at least 30 minutes.
1. Connect power to the unit.
2. Press the ON/OFF button on the remote controller or wired thermostat to turn the unit on.
3. Press the MODE button to scroll through the following functions, one at a time:
• COOL - Select lowest possible temperature.
• HEAT - Select highest possible temperature.
4. Let each function run for 5 minutes and perform the following checks:
LIST OF CHECKS TO PERFORM [ X ]
Unit is Properly Grounded [ ]
All Electrical Terminals are Properly Covered [ ]
Indoor and Outdoor Units are Solidly Installed [ ]
All Pipe Connection Points Do Not Leak [ ]
Water Drains Properly from Drain Hose without leaks [ ]
All Piping is Properly Insulated [ ]
Unit Performs COOL Function Properly [ ]
Unit Performs HEAT Function Properly [ ]

5. Double check all pipe connections. During operation, the pressure of the refrigerant system will
increase. This may reveal leaks that were not present during the initial leak check. Take time
during the test run to recheck all pipe connection points. Refer to Gas Leak Check section for
instructions.
6. Ensure the condensate flows smoothly through the drain. It may take up to one (1) minute
before the unit begins to drain, depending on the drainpipe. In new buildings, this should be
performed before finishing the ceiling.
