These instructions are primarily intended to assist qualified individuals experienced in the proper
installation of heating and/or air conditioning appliances. Some local codes require licensed
installation/service
personnel for this type of equipment. Read all instructions carefully before
starting the installation.
These units have been designed and tested for
capacity and efficiency in accordance with ARI
Standards. Split System Air Conditioning units
are designed for use with a wide variety of fossil
fuel furnaces, electric furnaces, air handlers,
and evaporator coil combinations.

Preferred

Location

of the Outdoor

Unit at

the Job Site -- Conduct a survey of the job
site to determine
the optimum location for
mounting
the outdoor
unit.
Overhead
obstructions,
poorly ventilated
areas, and
areas subject to accumulation of debris should
be avoided. The outdoor unit must be installed
in such a manner that airflow through the coil is
not obstructed and that the unit can be serviced.
Facility
Prerequisites
-- Electrical power
supplied must be adequate for proper operation
of the equipment. The system must be wired and
provided with circuit protection in accordance
with local building codes and the National
Electrical Code.
Minimum Circuit Ampacity-Electrical wiring
to the equipment must be compatible and in
compliance with the minimum circuit ampacity
listed on the outdoor unit data label.
Maximum Fuse/Circuit Breaker Size-- Circuit
protection for the outdoor unit must be compatible
with the maximum fuse/circuit breaker size listed
on the outdoor unit data label.

4. _NSTALLING
Slab Mount

--

THE OUTDOOR

The site selected

UNiT

for a slab

mount installation requires a stable foundation
and one not subject to erosion. The slab should
be level and anchored (if necessary)
prior to
placing the equipment on the slab.

Refrigerant and electrical lines should be routed
through suitably waterproofed
openings to
prevent water leaking into the structure.

5. NSTALMNG

THE NDOOR

UNIT

The indoor section of the unit should be installed
before proceeding with the routing of refrigerant
piping. Consult the Installation instructions of
the indoor unit (i.e., air handier, fan coil unit,
etc.) for details regarding installation.

6. CONNECTING
REFRIGERANT
TUBING BETWEEN
THE _NDOOR
AND

OUTDOOR

UNiT

Generam information
-- Once the outdoor and
indoor unit placement has been determined,
route the refrigerant
tubing between
the
equipment in accordance with sound installation
practices. Refrigerant tubing should be routed
in a manner that minimizes the length of tubing
and the number of bends in the tubing.
Refrigerant tubing should be supported in a
manner that the tubing will not vibrate or abrade
during system operation. Tubing should be kept
clean of foreign debris during installation and
installation
of a liquid line filter drier is
recommended if cleanliness or adequacy of
system evacuation is unknown or compromised.
Every effort should be made by the installer to
ensure that the field installed
refrigerant
containing components of the system have been
installed in accordance with these instructions
and sound installation practices so as to insure
reliable system operation and longevity.
The
maximum
recommended
interconnecting
refrigerant line length is 75 feet, and the vertical
elevation difference between the indoor and
outdoor sections should not exceed 20 feet.
Optiona! Equipment
-- Optional equipment
(i.e.: filter/driers, liquid line solenoid valves, etc.)
should be installed in strict accordance with the
manufacturer's Installation Instructions.

WARNING:
Ensure

electrical

power

to the unit is off

prior to performing
the following
steps.
Failure
to do so may cause
personal
injury

or death.

Air FHters -- Ensure air filters are clean and in
place prior to operating the equipment.
Thermostat-Set the room thermostat function
switch to OFF, fan switch to AUTO, and move
the temperature set-point to it's highest setting.
Prior to applying electrical power to the outdoor
unit, ensure that the unit has been properly and
securely grounded.
Prior to applying electricity to the outdoor unit,
ensure power supply connections have been
made at the facility power interface and at the
outdoor unit.
Outdoor Unit -- Ensure the outdoor coil and
top of the unit are free from obstructions and
debris, and all equipment access/control panels
are in place.

Short CycJe Protection
(select models) -With the system operating in "Cooling" mode,
note the temperature setting of the thermostat,
and gradually raise the set-point temperature
until the outdoor unit and indoor blower deenergize.
Immediately
lower the set-point
temperature of the thermostat to it's original
setting and verify that the indoor blower is
energized and that the outdoor unit remains deenergized.
Verify that, after approximately 5
minutes, the outdoor unit energizes and that the
temperature of the air supplied to the facility is
cooler than ambient temperature.
Heating -- If provided with heating equipment,
lower the thermostat temperature to the lowest
obtainable setting and set the thermostat function
switch to "Heating."
The indoor blower and
outdoor unit should stop running. Increase the
set-point temperature of the thermostat to the
maximum
setting. Verify that the heating
equipment has been energized (i.e., fossil fuel
burner operating, etc.) and that the indoor blower
energizes after a short period of time. Feel the
air being circulated by the indoor blower and
verify that it is warmer than ambient temperature.
Listen for any unusual noises. If present, locate
and determine the source of the noise and
