Damper Door; Make-Up Air Module (Muam) - Haier GE APPLIANCES AZ45E07D 5 Series Technical Service Manual

Damper Door

This feature allows outside air into the room. The
door is secured with two screws from the factory
that must be removed upon installation if the
customer would like to use this feature. The
damper assembly consists of a door, filter, rod
and wing nut. The wing nut can be loosened and
the rod may be slid back which opens the door. It
then can be locked into place by tightening the
wing nut.

Make-Up Air Module (MUAM)

The hospitality industry has many building and
occupancy codes they must follow. One of
those codes is for introducing fresh air into guest
spaces. Past codes allowed fresh air to pass
under the entry door or a separate vent into the
room. Some GE Appliances Zonelines have a
fresh air feature built into the product, this feature
is called a Make Up Air Module. The feature
includes a self-contained sealed system and
control module with a motorized duct door system.
This feature allows outdoor air to be conditioned
and enter the room through a ducted bulkhead
assembly.
The MUAM is designed to turn the compressor off
when outdoor temperature is below 50°F or
if relative humidity is lower than 55%. It will turn
on when relative humidity is above 55%. The
module is automatically turned on and off by the
microcontroller contained within the module's
electrical box.
The system is comprised of two components
which are the MUAM and the damper door. The
MUAM is attached to the base pan and includes
all sealed system components, fans and
controls for the MUAM. The damper door is an
assembly that is separate from the module and
is installed in the bulkhead opening.
