GENERAL

Every unit includes a well-insulated cabinet, copper
tube/aluminum fin coil with interlaced circuiting
arrangement, 1" throwaway filters, centrifugal blower
with a fixed pitch sheave, and a blower motor with vari­able pitch sheave. (FEH240 doesn’t ship with Motor &
Drive - field installation required).

They also include 2 filter driers, 2 expansion valves
and distributors that are only used during the cooling
cycle plus a check valve to provide the proper flow of
refrigerant through the unit during both the cooling and

heating cycles...

Improper installation may create a condition
where the operation of the product could
cause personal injury or property damage.

The controls include 208/230/460 volt transformer,
blower motor contactor and relay, and a low voltage
terminal block.

The units are shipped in the vertical position ready for
field installation. For horizontal installation, the blower
module can be repositioned in the field as shown on
Page 8 for maximum flexibility.

All forms referenced in this instruction may be ordered
from:

Standard Register
2101 West Tecumseh Road
Norman, Oklahoma 73069
Toll Free Fax [phone]

This instruction covers the installation of the indoor
unit. For information on the installation and operation
of the matching outdoor unit, refer to PN 035-16192-

001.
Installer should pay particular attention to the words:

NOTE, CAUTION and WARNING. Notes are intended
to clarify or make the installation easier. Cautions are
given to prevent equipment damage. Warnings are
given to alert the installer that personal injury and/or
equipment damage may result if the installation proce-

dure is not handled properly.

This product must be installed in strict compli­ance with the enclosed installation instruc­tions and any applicable local, state, and
national codes including but not limited to,
building, electrical and mechanical codes.

As soon as a unit is received, it should be inspected for
possible damage during transit. If damage is evident,
the extent of the damage should be noted on the car­rier’s freight bill. A separate request for inspection by
the carrier’s agent should be made in writing.

INSTALLATION

LIMITATIONS

Theses units must be installed in accordance with all
national and local safety codes. If no local codes
apply, installation must conform with the appropriate
national code. Units are designed to meet National
Safety Code Standards. If components are to be
added to a unit to meet local codes, they are to be
installed at the dealer’s and/or the customer’s expense.
See Table 2 for application data.

RIGGING

Be careful when moving the unit. Do not remove any
packaging until the unit is near its final location.

The packaging consists of a bottom wooden skid that
can be lifted with a fork truck from any direction, a plas­tic bag that covers the entire unit, and strapping that
secures the plastic bag to the bottom skid.

These units can be rigged with slings under the bottom
skid.

LOCATION

These indoor units are not designed for outdoor instal­lation. They must be located within the building struc­ture, either inside or outside the conditioned space.

The units should be located as close to the outdoor
units as practical and positioned to minimize bends in
the refrigerant piping.

Units being installed vertically or horizontally can be set
directly on a floor or platform, or they can be supported

by metal or wooden beams.

Be careful when attaching the hanger rods.
Use a washer with a back-up nut on each rod
and tighten down against the cabinet so they
will not be allowed to turn or slip.

Units being installed horizontally can be suspended
from above. Units being installed horizontally can be
suspended from above by using a field installed Hori­zontal Suspension Kit PN# 1HH0451. Refer to Figures
2 and 3 for their location and the individual load on
each hanger rod.

Spreader bars should be used to prevent
slings from crushing the unit panels and
frame.

Before rigging any unit, determine its weight from Table

1.

CLEARANCES

The clearances listed on unit dimensions drawing
(Pages 18 and 19) are required for the proper service
and operation of the unit.
