however it may be advisable to install some additional source of heat, such as electric
baseboard if the Sun Room is to be used in temperatures below 24 DegF.
Below 24 DegF the air temperature delivered from the unit will be close to body
temperature making it feel uncomfortable, as when the Outdoor temperature falls the

cycles.
This will assist in truly making the Sun Room a room to be enjoyed in comfort all year

recommends that Wind Baffles be installed on both the Coil Inlet and Fan Outlet of the
Outdoor unit. Please contact
DuctlessAire
directly for details of the design requirements
for the Wind Baffles.
We also recommend using these Wind Baffles in applications where the units may be
exposed to prevailing winds blowing though the condenser coils. These winds may cause
the unit to over condense and freeze the indoor unit, or allow liquid refrigerant to be
inadvertently slugged back into the compressor.
Installing the ICM326H Fan Speed Controller
The controller should be located per the instructions provided, it is not weatherproof,
therefore should be mounted inside the compressor compartment of the Outdoor unit.
DuctlessAire

cut out speed setting dials to 1/3 off the MINIMUM position.
