664 01 3001

Blower Cabinet

Installation Instructions
NOTE: Short duct runs tend to increase noise level.

Location
Select the best position which suits the installation site
conditions.
The location should provide adequate
structural support, space in the 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.

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
Figure 2

Attach Coil Cabinet to Wall

connections to meet FHA requirements. (See Fig. 3.)
These connections have 3/4-in. female pipe threads.
Tubing for all condensate drains should be a minimum of
7/8-in. OD. Drain lines from condensate pan to exterior of
unit must be plastic pipe. Drain should be pitched
downward at a slope of 1 in. per 10 ft.
If coil is located in or above a living space where damage
may result from condensate overflow, a separate 3/4-in.
drain must be provided from secondary drain connection.
Run this drain to a place in compliance with local
installation codes where it will be noticed when unit is
operational.
Condensate flowing from secondary drain indicates a
plugged primary drain.
Install a 3-in. trap in condensate drain line as close to coil
as possible. Make sure that the top of trap is below
connection to drain pan to prevent condensate from
overflowing drain pan. Prime trap with water. Insulate drain
if located above a living area and test condensate line for
leaks.
Consult local codes for additional
restrictions
or
)recautions.
Figure 3

NOTE: Do not remove seals from coil until tubing
connections are ready to be made. See instructions
packaged with outdoor unit for connecting refrigerant
tubes.
Before
connecting
refrigerant
tubing,
be
sure
factory-supplied indoor refrigerant flow-control device is
correct for outdoor unit size used. Refer to outdoor unit
installation instructions.
When changing piston, use a backup wrench and do not
over tighten. Maximum torque should not exceed 30 ft-lb.
(See Fig. 3.)
Move unit into place and install refrigerant tubing as
follows:
1. Route tubing to connection points.
2. Remove plugs from liquid and suction tubes.
3. Clean and braze tubing into place.
