Application and Location
General
These instructions explain the recommended method to install the
air cooled remote type condensing unit, the interconnecting
refrigerant tubing and the electrical wiring connections to the unit.
The condensing units are to be used in conjunction with the
matching evaporator coils or evaporator blower units for comfort
cooling applications as shown in the specification sheet.
These instructions and any instructions packaged with any separate
equipment required to make up the entire air conditioning system
should be carefully read before beginning the installation. Note
particularly "Starting Procedure" and any tags and/or labels
attached to the equipment.
While these instructions are intended as a general recommended
guide, they do not supersede any national and/or local codes in any
way. Authorities having jurisdiction should be consulted before the
installation is made.
Shipping Damage
Upon receipt of equipment, the carton should be checked for
external signs of shipping damage. If damage is found, the
receiving party must contact the last carrier immediately,
preferably in writing, requesting inspection by the carrier's agent.
Application
Size of unit for a proposed installation should be based on heat
loss calculation and air duct sizing made according to methods of
Air Conditioning Contractors of America. The air duct should be
installed in accordance with the Standards of the National Fire
Protection Association for the Installation of Air Conditioning and
Ventilating Systems of Other Than Residence Type, NFPA 90A,
and Residence Type Warm Air Heating and Air Conditioning
Systems, NFPA 90B. Where local regulations are at a variance
with instructions, installer should adhere to local codes.

Location
Figure 2 — Installation Clearance
The condensing unit is designed to be located outside with free and
unobstructed condenser air inlet and discharge. It must also permit
access for service and installation. Condenser air enters the coil
and discharges. Refrigerant and electrical connections are made
from the rear of the unit as shown in Figure 2 with electrical
service access.
Mounting Unit Outside on Slab
A solid level base or platform, capable to support the unit's
weight, must be set at the outdoor unit predetermined location. The
base should be at least two inches larger than the base dimensions
of the unit and at least two inches higher than surrounding grade
level. The required unit minimum installed clearances must be
maintained as called out in Figure 2 when locating and setting the
base.
Remove the unit from its shipping carton and position the unit on
the prepared base or platform.
Do not attach the unit or its base to the building structure to avoid
the transmission of noise into the occupied area.
NOTE: These units employ internally sprung compressors;
therefore, it is not necessary to remove or loosen the base
mounting bolts on the compressor prior to operation.
Consideration should be given to the electrical and tubing
connections when placing the unit to avoid unnecessary bends or
length of material.
Important Installer Note
For improved start-up performance, wash the indoor coil with a
dishwater detergent.
Installation Refrigerant Tubing
The information that follows on installing refrigerant tubing and
for changing the system orifice (if required) covers applications
listed in the front of this installation instruction only. Although
other indoor units may be of similar construction, the installation
instructions for these units should be consulted for proper
installation of those units prior to installation.
