Corrective Action
This is normal operation of the unit.
During start up, unit is preparing
warm air.
• In heating mode, ice/frost is built up on the
coils when the outside temperature falls.
• Defrost mode removes a layer of frost from the
coil.
• Wait until this operation is completed. It takes
about 15 minutes.
Heating capacity of the unit may not be suffi-
cient to effectively warm air.
• Check to see if timer function has been set to
turn off at designated time.
• Check timer settings and make adjustments as
needed.
• Auto restart is the default setting and is re-
booting the system.
• If you experience frequent power failures, it
is helpful to verify that system is set to auto
restart so that the unit can re-power quickly.
• Wait until the auto clean mode has finished its
function.
• You may turn this feature off.
If the room temperature is lowered the mist will
stop forming.
• Install drain hose under the base pan.
• Contact the installer of the unit.
