GENERAL
The information contained in this manual has been prepared to assist in the proper
installation, operation and maintenance of the air conditioning system. Improper
installation, or installation not made in accordance with these instructions, can
result in unsatisfactory operation and/or dangerous conditions, and can cause the
related warranty not to apply.
Read this manual and any instructions packaged with separate equipment required
to make up the system prior to installation. Retain this manual for future reference.
To achieve optimum efficiency and capacity, the indoor cooling coils listed in the condensing unit specification sheet should be used.
APPLICATION
Before installing any air conditioning equipment, a duct analysis of the structure and
a heat gain calculation must be made. A heat gain calculation begins by measuring
all external surfaces and openings that gain heat from the surrounding air and
quantifying that heat gain. A heat gain calculation also calculates the extra heat
load caused by sunlight and by humidity removal.
There are several factors that the installers must consider:
• Outdoor unit location• Proper equipment evacuation
• System refrigerant charge• Indoor unit airflow
• Indoor unit blower speed• Supply and return air duct design and sizing
• System air balancing• Diffuser and return air grille location and sizing
CORROSIVE ENVIRONMENT
The metal parts of this unit may be subject to rust or deterioration if exposed to a
corrosive environment. This oxidation could shorten the equipment’s useful life.
Corrosive elements include, but are not limited to, salt spray, fog or mist in seacoast
areas, sulphur or chlorine from lawn watering systems, and various chemical contaminants from industries such as paper mills and petroleum refineries.
If the unit is to be installed in an area where contaminants are likely to be a problem, special attention should be given to the equipment location and exposure.
•Avoid having lawn sprinkler heads spray directly on the unit cabinet.
•In coastal areas, locate the unit on the side of the building away from the waterfront.
•Shielding provided by a fence or shrubs may give some protection, but cannot
violate minimum airflow and service access clearances.
•Elevating the unit off its slab or base enough to allow air circulation will help
avoid holding water against the basepan.
Regular maintenance will reduce the build-up of contaminants and help to protect
the unit’s finish.

RESULTING IN SEVERE PERSONAL INJURY OR DEATH.
•Frequent washing of the cabinet, fan blade and coil with fresh water will remove
most of the salt or other contaminants that build up on the unit.
•Regular cleaning and waxing of the cabinet with an automobile polish will provide some protection.
•A liquid cleaner may be used several times a year to remove matter that will not
wash off with water.
Several different types of protective coatings are offered in some areas. These
coatings may provide some benefit, but the effectiveness of such coating materials
cannot be verified by the equipment manufacturer.
LOCATING UNIT
CONDENSER LOCATION
Consult local and national building codes and ordinances for special installation
requirements. Following location information will provide longer life and simplified
servicing of the outdoor condenser.
NOTE: These units must be installed outdoors. No ductwork can be attached, or
other modifications made, to the discharge grille. Modifications will affect performance or operation.
OPERATIONAL ISSUES
•IMPORTANT: Locate the condenser in a manner that will not prevent, impair or
compromise the performance of other equipment horizontally installed in proximity to the unit. Maintain all required minimum distances to gas and electric
meters, dryer vents, exhaust and inlet openings. In the absence of National
Codes, or manaufacturers’ recommendations, local code recommendations and
requirements will take presidence.
•Refrigerant piping and wiring should be properly sized and kept as short as possible to avoid capacity losses and increased operating costs.
•Locate the condenser where water run off will not create a problem with the
equipment. Position the unit away from the drip edge of the roof whenever possible. Units are weatherized, but can be affected by the following:
o Water pouring into the unit from the junction of rooflines, without protective
guttering. Large volumes of water entering the condenser while in operation
can impact fan blade or motor life, and coil damage may occur to a heat
pump if moisture cannot drain from the unit under freezing conditions.
•Closely follow clearance recommendations on Page 3.
o 24” to the service panel access
o 60” above condenser fan discharge (unit top) to prevent recirculation
o 6” to condenser coil grille air inlets (per condenser).
FOR CONDENSERS WITH SPACE LIMITATIONS
In the event that a space limitation exists, we will permit the following clearances:
Single Unit Applications: Clearances below 6 inches will reduce unit capacity and
efficiency. Do not reduce the 60-inch discharge, or the 24-inch service clearances.
Multiple Unit Applications: When multiple condenser grille sides are aligned, a 6inch per unit clearance is recommended, for a total of 12" between two units. Two
combined clearances below 12 inches will reduce capacity and efficiency. Do not
reduce the 60-inch discharge, or 24-inch service, clearances.
•Do not obstruct the bottom drain opening in the condenser base pan. It is
essential to provide defrost condensate drainage to prevent possible refreezing
of the condensation. Provide a base pad for mounting the unit, which is slightly
pitched away from the structure. Route condensate off the base pad to an area
which will not become slippery and result in personal injury.
6
STEP 4: Drill four pilot holes in pad, ensuring that the hole is at least 1/4” deeper
than the concrete screw being used.
STEP 5: Center basepan over pre-drilled holes and insert concrete screws.
STEP 6: Tighten concrete screws.
NOTE: Do not over-tighten the concrete screws. Doing so can weaken the
integrity of the concrete screw and cause it to break.
STEP 7: Finish unit assembly per unit’s installation instructions.
UNIT MOUNTING
If elevating the condensing unit, either on a flat roof or on a slab, observe the
following guidelines.
•The base pan provided elevates the condenser coil 3/4” above the base pad.
•If elevating a unit on a flat roof, use 4” x 4” (or equivalent) stringers positioned
to distribute unit weight evenly and prevent noise and vibration.
NOTE: Do not block drain openings shown in Figure 1.
FACTORY-PREFERRED TIE-DOWN METHOD
FOR CONDENSING UNITS
IMPORTANT: These instructions are intended as a guide to securing equipment for
wind-load ratings of “120 MPH sustained wind load” and “3-second, 150 MPH gust.”
While this procedure is not mandatory, the Manufacturer does recommend that
equipment be properly secured in areas where high wind damage may occur.
STEP 1: Before installing, clear pad of any dirt or debris.
IMPORTANT: The pad must be constructed of industry-approved materials,
and must be thick enough to accommodate the concrete fastener.
STEP 2: Center base pan on pad, ensuring it is level.
STEP 3: Using basepad as a guide, mark spots on concrete where 4 holes will be
drilled (see Figure 2).
CUSTOMER SATISFACTION ISSUES
•The condenser should be located away from the living, sleeping and recational spaces of the owner and those spaces on adjoining property.
•To prevent noise transmissionm, the mounting pad for the outdoor unit should
not be connected to the structure, and should be located sufficient distance
above grade to prevent ground water from enteriing the unit.

Physical Properties: R-410A has an atmospheric boiling point of -62.9°F and its
saturation pressure at 77°F is 224.5 psig.
Composition: R-410A is an azeotropic mixture of 50% by weight difluoromethane
(HFC-32) and 50% by weight pentafluoroethane (HFC-125).
Pressure: The pressure of R-410A is approximately 60% (1.6 times) greater
than R-22. Recovery and recycle equipment, pumps, hoses and the like need to
h
ave design pressure ratings appropriate for R-410A. Manifold sets need to range
up to 800 psig high-side and 250 psig low-side with a 550 psig low-side retard.
Hoses need to have a service pressure rating of 800 psig. Recovery cylinders need
to have a 400 psig service pressure rating. DOT 4BA400 or DOT BW400.
Combustibility: At pressures above 1 atmosphere, mixture of R-410A and air can
b
ecome combustible. R-410A and air should never be mixed in tanks or supply
lines, or be allowed to accumulate in storage tanks. Leak checking should
never be done with a mixture of R-410A and air. Leak checking can be per-
formed safely with nitrogen or a mixture of R-410A and nitrogen.
QUICK REFERENCE GUIDE FOR R-410A
• R-410A refrigerant operates at approximately 60% higher pressure (1.6 times)
than R-22. Ensure that servicing equipment is designed to operate with R-410A.
• R-410A refrigerant cylinders are pink in color.
• R-410A, as with other HFC’s is only compatible with POE oils.
• Vacuum pumps will not remove moisture from oil.
• R-410A systems are to be charged with liquid refrigerants. Prior to March 1999,
R-410A refrigerant cylinders had a dip tube. These cylinders should be kept
upright for equipment charging. Post March 1999 cylinders do not have a dip
tube and should be inverted to ensure liquid charging of the equipment.
• Do not install a suction line filter drier in the liquid line.
• A liquid line filter drier is standard on every unit. Only manufacturer approved liq-
uid line filter driers can be used. These are Sporlan (CW083S) and Alco
(80K083S) driers. These filter driers are rated for minimum working pressure of
600 psig.
• Desiccant (drying agent) must be compatible for POE oils and R-410A.
REPLACEMENT UNITS
To prevent failure of a new condensing unit, the existing evaporator tubing system
must be correctly sized and cleaned or replaced. Care must be exercised that the
expansion device is not plugged. For new and replacement units, a liquid line filter
drier should be installed and refrigerant tubing should be properly sized. Test the oil
for acid. If positive, a suction line filter drier is mandatory.
IMPORTANT: WHEN REPLACING AN R-22 UNIT WITH AN R-410A UNIT,
EITHER REPLACE THE LINE SET OR ENSURE THAT THE EXISTING LINE SET
IS THOROUGHLY CLEANED OF ANY OLD OIL OR DEBRIS.
EVAPORATOR COIL
REFER TO EVAPORATOR COIL MANUFACTURER’S INSTALLATION
INSTRUCTIONS.
IMPORTANT: The manufacturer is not responsible for the performance and opera-
tion of a mismatched system, or for a match listed with another manufacturer’s coil.
!
CAUTION
Only use evaporators approved for use on R-410A systems. Use of existing R-22
evaporators can introduce mineral oil to the R-410A refrigerant forming two different liquids and decreasing oil return to the compressor. This can result in compressor failure.
