Test Run | 33
DOUBLE-CHECK PIPE CONNECTIONS
During operation, the pressure of the refrigerant circuit will
increase. This may reveal leaks that were not present during your
initial leak check. Take time during the Test Run to double-check
that all refrigerant pipe connection points do not have leaks.
Refer to Gas Leak Check section for instructions.
5. After the Test Run is successfully complete, and you confirm
that all checks points in List of Checks to Perform have PASSED,
do the following:
a. Using remote control, return unit to normal operating
temperature.
b. Using insulation tape, wrap the indoor refrigerant pipe
connections that you left uncovered during the indoor unit
installation process.
IF AMBIENT TEMPERATURE IS BELOW 17°C (63°F)
You can’t use the remote controller to turn on the COOL function
when the ambient temperature is below 17°C. In this instance,
you can use the MANUAL CONTROL button to test the COOL
function.
1. Lift the front panel of the indoor unit, and raise it until it
clicks in place.
2. The MANUAL CONTROL button is located on the right-hand
side of the unit. Press it 2 times to select the COOL function.
See Fig 9.1.
3. Perform Test Run as normal.
