The metal parts of this unit may be subject to rust or deterioration in adverse environmental conditions. This oxidation could shorten the equipment’s useful life. 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
are especially corrosive.
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.
1. Avoid having lawn sprinkler heads spray directly on the unit cabinet.
2. In coastal areas, locate the unit on the side of the building away from the waterfront.
3. Shielding provided by a fence or shrubs may give some protection.
4. 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 buildup of contaminants and help to protect
the unit’s finish.
WARNING
!
DISCONNECT ALL POWER TO THE UNIT BEFORE STARTING MAINTENANCE.
FAILURE TO DO SO CAN RESULT IN SEVERE ELECTRICAL SHOCK OR
DEATH.
1. 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.
2. Regular cleaning and waxing of the cabinet with an automobile polish will provide
some protection.
3. 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.
The best protection is frequent cleaning, maintenance and minimal exposure to
contaminants.

A. GENERAL
The Packaged Air Conditioner is available without heat or with 5, 7, 10, 15, or 20 kW
electric heat. Cooling capacities of 2, 2
available.
The units are weatherized for mounting outside of the building.
The information on the rating plate is in compliance with the FTC and DOE rating for sin-
gle phase units.
1
⁄2, 3, 31⁄2 , 4 and 5 nominal tons of cooling are
B. MAJOR COMPONENTS
The unit includes a hermetically-sealed refrigerating system (consisting of a compressor,
condenser coil, evaporator coil with refrigerant metering device), a circulation air blower,
a condenser fan, and all necessary internal electrical wiring. The cooling system of these
units is factory-evacuated, charged and performance tested. Refrigerant amount and
type are indicated on rating plate.
C. R-410A REFRIGERANT
All units are factory charged with R-410A refrigerant.
1. Specification 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 units.
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 performed safely with nitrogen or a
mixture of R-410A and nitrogen.
2. 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.
• R-410A, as with other HFC’s is only compatible with POE oils.
• Vacuum pumps will not remove moisture from POE oil.
• R-410A systems are to be charged with liquid refrigerants. Prior to March 1999, R410A 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.
• Desiccant (drying agent) must be compatible for POE oils and R-410A.
3. Evaporator Coil / TXV
The thermostatic expansion valve is specifically designed to operate with R-410A. DO
NOT use an R-22 TXV. The existing evaporator must be replaced with the factory
specified TXV evaporator specifically designed for R-410A.
4. Tools Required For Installing & Servicing R-410A Models
Manifold Sets:
-Up to 800 PSIG High side
-Up to 250 PSIG Low Side
-550 PSIG Low Side Retard
Manifold Hoses:
-Service Pressure Rating of 800 PSIG

VI.INSTALLATION
A. GENERAL
1. PRE-INSTALLATION CHECK-POINTS
Before attempting any installation, the following points should be carefully consid-
ered:
a. Structural strength of supporting members.
(rooftop installation)
b. Clearances and provision for servicing.
c. Power supply and wiring.
d. Air duct connections.
e. Drain facilities and connections.
f. Location for minimum noise.
2. LOCATION
These units are designed for outdoor installations. They can be mounted on a
slab or rooftop. They are not to be installed within any part of a structure such as
an attic, crawl space, closet, or any other place where condenser air flow is
restricted or other than outdoor ambient conditions prevail. Since the application
of the units is of the outdoor type, it is important to consult your local code authorities at the time the first installation is made.
B. OUTSIDE SLAB INSTALLATION
(Typical outdoor slab installations are shown in Figure 2.)
1. Select a location where external water drainage cannot collect around the unit.
2. Provide a level concrete slab extending 3" beyond all four sides of the unit. The
slab should be sufficient above grade to prevent ground water from entering the
unit.
IMPORTANT: To prevent transmission of noise or vibration, slab should not be
connected to building structure.
3. The location of the unit should be such as to provide proper access for inspection
and servicing.
4. Locate unit where operating sounds will not disturb owner or neighbors.
5. Locate unit so roof runoff water does not pour directly on the unit. Provide gutter
or other shielding at roof level. Do not locate unit in an area where excessive
snow drifting may occur or accumulate.
C. CLEARANCES
The following minimum clearances must be observed for proper unit performance
and serviceability.
1. Provide 30" minimum clearance at the front and 18" on the right side of the unit
for service access. Provide 12" minimum clearance on the left side of the unit for
air inlet.
2. Provide 60" minimum clearance from top of unit.
3. Unit is design certified for application on combustible flooring with 0" minimum
clearance.
4. See Figure 2 for illustration of minimum installation-service clearances.
D. ROOFTOP INSTALLATION
1. Before locating the unit on the roof, make sure that the strength of the roof and
beams is adequate at that point to support the weight involved. (See specification
sheet for weight of unit.) This is very important and user’s responsibility.
2. The unit should be placed on a solid and level platform of adequate strength.

DO NOT, UNDER ANY CIRCUMSTANCES, CONNECT RETURN DUCTWORK TO
ANY OTHER HEAT PRODUCING DEVICE SUCH AS A FIREPLACE INSERT,
STOVE, ETC. UNAUTHORIZED USE OF SUCH DEVICES MAY RESULT IN FIRE,
CARBON MONOXIDE POISONING, EXPLOSION, PROPERTY DAMAGE,
SEVERE PERSONAL INJURY OR DEATH.
Place the unit as close to the space to be air conditioned as possible allowing clearance
dimensions as indicated. Run ducts as directly as possible to supply and return outlets.
Use of non-flammable waterproof flexible connectors on both supply and return connections at the unit to reduce noise transmission is recommended.
It is preferable to install the unit on the roof of the structure if the registers or diffusers
are located on the wall or in the ceiling. Consider a slab installation when the registers
are low on a wall or in the floor.
On ductwork exposed to outside air conditions of temperature and humidity, use a minimum of 2" of insulation and a vapor barrier. Distribution system in attic, furred space or
crawl space should be insulated with at least 2" of insulation with vapor barrier. One-half
to 1" thickness of insulation is usually sufficient for ductwork inside the air conditioned
space.
Provide balancing dampers for each branch duct in the supply system. Properly support
the ductwork from the structure.
