2.2 APPLICATION
Before specifying any air conditioning equipment, a survey 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.
Air conditioning systems are sized on the cooling load calculation. There are two
capacities that enable the equipment to provide comfort. The first is sensible capacity.
Sensible heat is the heat energy measured on the dry bulb thermometer as it is
added or removed.
The second form of heat is called latent or hidden heat. This is heat held in the
humidity in the air.
A properly-sized unit removes both forms of heat, producing a comfortable living
space. An oversized system cycles on and off too quickly and does not properly
remove humidity, producing an uncomfortable living space. Select the indoor and
outdoor equipment combination based on the manufacturer’s engineering data.
After the equipment combination has been selected, satisfying both sensible and
latent conditioning requirements, the system must be properly installed. Only then
can the unit provide the comfort the manufacturer intends.
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

3.0 LOCATING UNIT
3.1 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.

MAINTENANCE. FAILURE TO DO SO CAN CAUSE ELECTRICAL SHOCK
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 a good automobile polish will
provide some protection.
• A good 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.
3.2 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.

3.3 Operational Issues
• IMPORTANT: Locate the unit in a manner that will not prevent, impair or com-
promise 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
anufacturers’ recommendations, local code recommendations and require-
m
ments will take precedence.
• Refrigerant piping and wiring should be properly sized and kept as short as
possible to avoid capacity losses and increased operating costs.
• Locate the unit 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 heat pump 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.
o Freezing moisture, or sleeting conditions, can cause the cabinet to ice-over
prematurely and prevent heat pump operation, requiring backup heat, which
generally results in less economical operation.
• Closely follow clearance recommendations on Page 6.
o 24” to the service panel access
o 60” above heat pump fan discharge (unit top) to prevent recirculation
o 6” to heat pump coil grille air inlets
3.4 For Units With Space Limitations
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.
3.5 Customer Satisfaction Issues
• The condensing unit should be located away from the living, sleeping and
recreational spaces of the owner and those spaces on adjoining property.
• To prevent noise transmission, 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 entering the unit.
3.6 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 heat pump 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 (see Figure 2).
NOTE: Do not block drain openings shown in Figure 1.
3.7 Factory-Preferred Tie-Down Method for Outdoor Units
IMPORTANT: The Manufacturer approved/recommended method is a guide to securing equipment for wind and seismic loads. Other methods might provide the same
result, but the Manufacturer method is the only one endorsed by Manufacturer for
securing equipment where wind or earthquake damage can occur. Additional information is available in the PTS (Product Technical Support) section of the Manufacturer
website Rheemote.net and can be found as a listing under each outdoor model. If you
do not have access to this site, your Distributor can offer assistance.

4.2 Specifications of R-410A:
Application: R-410A is not a drop-in replacement for R-22; equipment designs
must accommodate its higher pressures. It cannot be retrofitted into R-22 heat
pumps.
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
have 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
become 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.
4.3 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 liquid 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.
