Air Conditioning units are designed for use with a wide variety of fossil fuel furnaces, electric furnaces, air handlers, and
evaporator coil combinations.
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.
USER’S INFORMATION
IMPORTANT
Read this owner information to become familiar with the
capabilities and use of your appliance. Keep this with
literature on other appliances where you have easy access
to it in the future. If a problem occurs, check the instructions
and follow recommendations given. If these suggestions
don’t eliminate your problem, call your servicing contractor
.
OPERATING INSTRUCTIONS
To Operate Your Air Conditioner for Cooling —
1. Set the thermostat system switch to COOL or AUTO
and the thermostat fan switch to AUTO. (See Figure 1)
2. Set the thermostat temperature to the desired
temperature level by pressing the WARMER or COOLER
button. Please refer to the separate detailed thermostat
user's manual for complete instructions regarding
thermostat programming. The outdoor unit and indoor
blower will both cycle on and off to maintain the indoor
temperature at the desired cooling level.
To Operate Your Furnace for Heating —
1. Set the thermostat system switch to HEAT or AUTO and
the thermostat fan switch to AUTO. (See Figure 1)
2. Set the thermostat temperature to the desired
temperature level by pressing the WARMER or COOLER
button. Please refer to the separate detailed user's
manual for complete thermostat programming
instructions. The furnace and indoor blower will cycle on
and off to maintain the indoor temperature at the desired
heating level.
To Shut Off Your Air Conditioner —
Set the thermostat system switch to OFF and the thermostat
fan switch to AUTO. (See Figure 1)
The system will not operate, regardless of the thermostat
temperature setting.
To Operate the Indoor Blower Continuously —
Set the thermostat fan switch to ON (See Figure 1)
The indoor blower will start immediately, and will run
continually until the fan switch is reset to AUTO.
Figure 1. Typical Thermostat
The continuous indoor blower operation can be obtained
with the thermostat system switch set in any position,
including OFF.
The continuous indoor blower operation is typically used to
circulate the indoor air to equalize a temperature unbalance
due to a sun load, cooking, or fireplace operation.
To Maintain Your Air Conditioner —
CAUTION:
!
Be certain the electrical power to the outdoor
unit and the furnace/air handler is disconnected
before doing the following recommended
maintenance.
1. Regularly:
a. Clean or replace the indoor air filter at the start of each
heating and cooling season, and when an accumulation
of dust and dirt is visible on the air filter.
b. Remove any leaves and grass clippings from the coil in
the outdoor unit, being careful not to damage the
aluminum fins.
c. Check for any obstruction, such as twigs, sticks, etc.
!
CAUTION:
Do not over-oil, or oil motors not factoryequipped with oil tubes. The compressor is
hermetically “sealed” and does not require
lubrication.
2. Before Each Cooling Season:
If the furnace/air handler blower motor and the outdoor unit
fan motor(s) have oil tubes at the motor bearings, apply 10
drops of SAE No. 20 motor oil to each oil tube.

3. Before Calling a Service Technician, Be Certain:
a. The unit thermostat is properly set — see “To Operate
Your Air Conditioner for Cooling” and “To Operate Your
Furnace for Heating.”
b. The unit disconnect fuses are in good condition, and
the electrical power to the unit is turned on.
Read Your Warranty
Please read the separate warranty document completely. It
contains valuable information about your system.
prior to performing the installation and operational checkout
of the equipment.
3. SITE PREPARATION
Unpacking Equipment — Remove the cardboard carton
and Homeowner’s Package from the equipment.
1. GENERAL INFORMATION
Read the following instructions completely before performing
the installation.
Condensing Unit Section — Each condensing unit is
shipped with a refrigerant charge adequate to operate the
outdoor section with an indoor matching coil or air handler
and 15 feet of refrigeration line.
NOTE: DO NOT USE ANY PORTION OF THE CHARGE
FOR PURGING OR LEAK TESTING.
Matching coils and air handlers are shipped with a small
holding charge to pressurize them to keep out contaminants.
To release the pressure, read the indoor section of the
installation instructions carefully.
Liquid and Suction Lines — Refrigerant grade copper
tubing should be used when installing the system. Refrigerant
suction line tubing should be fully insulated.
Field Connections for Electrical Power Supply — All
wiring must comply with the current provisions of the “National
Electrical Code” (ANSI C1.) and with applicable local codes
having jurisdiction. Size of electrical conductors and circuit
protection must be in compliance with the information listed
on the outdoor unit data label.
Inspect for Damage — Inspect the equipment for damage
prior to installing the equipment at the job site. Ensure coil
fins are straight and, if necessary, comb fins to remove
flattened and bent fins.
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 should be installed no closer than 18 inches from the
outside walls of the facility and in an area free from
overhead obstructions to ensure unrestricted airflow
through the outdoor unit.
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.
2. SAFETY CONSIDERATIONS
Pressures Within the System — Split System Air
Conditioning equipment contains liquid and gaseous
refrigerant under pressure. Installation and servicing of this
equipment should be accomplished by qualified, trained
personnel thoroughly familiar with this type of equipment.
Under no circumstances should the homeowner attempt to
install and/or service the equipment without proper
supervision from trained and qualified service personnel.
WARNING:
!
Ensure all electrical power to the unit is off prior
to installing or servicing the equipment. Failure
to do so may cause personal injury or death.
Labels, Tags, Precautions — When working with this
equipment, follow all precautions in literature, on tags, and
on labels provided with the equipment. Read and thoroughly
understand the instructions provided with the equipment
4. INSTALLING THE OUTDOOR UNIT
Slab Mount — The site selected 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.
Cantilever Mount — The cantilever mount should be
designed with adequate safety factor to support the weight
of the equipment, and for loads the mount is subjected to
during operation. Installed equipment should be adequately
secured to the cantilever mount and levelled prior to operation
of the equipment.
Roof Mount — The method of mounting should be designed
so as not to overload roof structures nor transmit noise to
the interior of the structure. Refrigerant and electrical lines
should be routed through suitably waterproofed openings to
prevent water leaking into the structure.
