9.2.1. 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.
9.2.2. If ambient temperature is below 17°C (63°F)
You can't use the remote controller to turn on the COOL function when
