Slim Duct Unit Technical Overview
The Slim Duct Indoor Unit will act as evaporator coils during
cooling mode and condenser coils during heating mode.
This unit can operate with a motorized supply air louver or
it can have a LIMITED amount of ducting added to the unit’s
return and supply air duct connection anges. The return air
ducting can be connected to the end of the cabinet or the
bottom blank o plate can be removed for bottom return
conguration.
DIP Switches on the unit’s circuit board congure the fan
power to match the ducting conguration.
The Slim Duct cabinet is insulated so that it can be installed
in unconditioned air. The unit is well suited for mounting in
sots, attics, and garages.
These units have a built in condensate pump with an
associated condensate level switch. The condensate pump
is capable of lifting water out of the indoor unit. If high water
lift is needed, the water from the cassette pump should be
pumped into a eld supplied condensate pump with high lift
power.
Slim Duct units are controlled by a wired
controller only.
