GeneralInformation

The blower cabinet may be used for cooling or heat pump
operation with or without electric heat. Installations without

Installation or repairs made by unqualified persons can
result in hazards to you and others. Installation MUST

conform with local building codes and with the
National Electrical Code NFPA70 current edition.

The information contained in this manual is intended
for use by a qualified service technician familiar with

safety procedures and equipped with the proper tools
and test instruments.

Failure to carefully read and follow all instructions in
this manual can result in equipment malfunction,

property damage, personal injury and/or death.

electric heat, require a Cooling Control Kit. The cabinet
can be installed in an Upflow position ONLY.

Check Equipment

Unpack unit and move to final location. Remove carton,

taking care not to damage unit. Inspect equipment for
damage prior to installation. File claim with shipping

company if shipment is damaged or incomplete. Locate
rating plate on unit. It contains information needed to

properly install unit. Check rating plate to be sure unit
matches job specifications.

I Blower Cabinet

Location

Select the best position which suits the installation site
conditions. The location should provide adequate
structural support, space inthe front of the unit for service

access, clearance for return air and supply duct
connections, space for refrigerant piping connections and

condensate drain line connections.

See Clearances in Figure 1.
A front access panel is provided, which permits access to

blower assembly and electrical controls for removal and
servicing.

NOTE: Local codes may limit application of systems
without a ducted return to single story dwellings.

Installation Instructions

NOTE: Short duct runs tend to increase noise level.

When fan coil is equipped with an electric heater, install air
ducts in accordance with standards 90A and 90B of

National Fire Protection Association (NFPA). Use of

flexible connectors between ductwork and unit will prevent
transmission of vibration.

When electric heater is installed, use heat-resistant
material for a flexible connector between ductwork and unit

air discharge connection.

Ductwork passing through unconditioned space must be

insulated and covered with a vapor barrier.

NOTE: Unit is intended for nonducted return-air

applications. Local codes may limit this unit to single-level
applications.

Installation

The unit is designed for free-air return as enclosed in a
closet with Iouvered door or for flush mounting in a wall. A

factory-authorized Iouvered grille kit is available for flush

mount application (AMWK001WG).
When unit is installed in a closet with a Iouvered door in

return-air path, the free area of Iouvered opening in the
door must be a minimum of 2.25 sq ft. Either align door

opening with unit inlet or provide a l O-in. clearance

between door and unit.

If unit is to be flush mounted in a wall, provide adequate
support underneath base of unit. To assure proper

condensate drainage, be sure unit is level.

HangingCabinet

Cabinet may by hung from the wall using accessory

brackets (AMWK001MK). Use 1X 4 or2 X 4 support and a
spacer for the bottom across studs to support the unit.

Bottom spacer should be located above the bottom of the

unit so it holds the unit out from the wall in a vertical

position, See Figure 2,

CAUTION

Both wall support and spacer must be the same

thickness or the unit will not hang correctly and

Condensate Water will not drain correctly. Unit must
be vertical ortilted slightly forward which the support

bracket will do.

SupplyDuct

Connect supply-air duct over 3/4-in. flange provided on
supply-air opening. Secure duct to flange using applicable

fasteners for type of duct used, and seal duct-to-unit joint.
