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.
• Using remote control, return unit to the normal
operating temperature.
• Using insulation tape, wrap the indoor refrigerant pipe
connections that you left uncovered during the indoor
unit installation process.
Ambient Temperature is Below 63°F (17°C)
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
