WARNING
THE MANUFACTURER’S WARRANTY DOES NOT COVER
ANY DAMAGE OR DEFECT TO THE AIR CONDITIONER
CAUSED BY THE ATTACHMENT OR USE OF ANY COMPONENTS, ACCESSORIES OR DEVICES (OTHER THAN
THOSE AUTHORIZED BY THE MANUFACTURER) INTO,
ONTO OR IN CONJUNCTION WITH THE AIR CONDITIONER. YOU SHOULD BE AWARE THAT THE USE OF UNAUTHORIZED COMPONENTS, ACCESSORIES OR DEVICES
MAY ADVERSELY AFFECT THE OPERATION OF THE AIR
CONDITIONER AND MAY ALSO ENDANGER LIFE AND
PR O PERTY . THE MANUF A CTUR E R DIS C LAIM S ANY
RESPONSIBILITY FOR SUCH LOSS OR INJURY RESULTING FROM THE USE OF SUCH UNAUTHORIZED COMPONENTS, ACCESSORIES OR DEVICES.
This booklet contains the installation and operating instructions
for your air conditioner. There are a few precautions that
should be taken to d erive maximum satisfaction from it.
Improper installation can result in unsatisfactory operation or
dangerous conditions.
Read this booklet and any instructions packaged with separate
equipment required to make up the system prior to installation.
Give this booklet to the owner and explain its provisions. The
owner should retain this booklet for future reference.
III. CHECKING PRODUCT RECEIVED
Upon receiving the unit, inspect it for any damage from shipment. Claims for damage, either shipping or concealed, should
be filed immediately with the shipping company. Check the unit
model number, heating size, electrical characteristics, and
ccessories to determine if they are correct.
a
IV. EQUIPMENT PROTECTION FROM THE
ENVIRONMENT
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 direction 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.
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 a good
automobile polish will provide some protection.
3. 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.
The best protection is frequent cleaning, maintenance and
minimal exposure to contaminants.
V. SPECIFICATIONS
A. GENERAL
The Packaged Air Conditioner is available without heat or with
10, 15, 20, 30, 40 or 50 kW electric heat. Cooling capacities of
1
⁄2 , 81⁄2 , 10 and 121⁄2 nominal tons of cooling are available.
6, 7
Units are convertible from horizontal supply and return to bottom supply and return by relocation of supply and return air
access panels. See cover installation detail.
2
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 single phase units. The following information is for three phase units which are not covered under
he DOE certification program.
t
1. The efficiency rating of this unit is a product thermal efficiency rating determined under continuous operating conditions independent of any installed system.
B. MAJOR COMPONENTS
The unit includes a hermetically-sealed refrigerating system
(consisting of a compressor, condenser coil, evaporator coil
with thermal expansion valve), 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 indi-
ated on rating plate.
c
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 equip-
ment, 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.
• 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, 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.
• 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 exist-
ing 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
Recovery Cylinders:
-400 PSIG Pressure Rating
-Dept. of Transportation 4BA400 or BW400
!
CAUTION
R-410A systems operate at higher pressures than R-22 systems. Do not use R-22 service equipment or components on R410A equipment.
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.

VI. INSTALLATION
. GENERAL
A
1. PRE-INSTALLATION CHECK-POINTS
Before attempting any installation, the following points
should be carefully considered:
a. Structural strength of supporting members.
(rooftop installation)
b. Clearances and provision for servicing.
. Power supply and wiring.
c
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 Figures 6 and 7.)
1. Select a location where external water drainage cannot
collect around the unit.
2. Provide a level concrete slab extending 3" [76.2 mm]
beyond all four sides of the unit. The slab should be sufficient above grade to prevent ground water from entering the unit. IMPOR TANT: 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 48" [1219.2 mm] minimum clearance at the front
of the unit. Provide 18" [457.2 mm] minimum clearance
at all other sides of the unit.
2. Provide 60" [1524 mm] minimum clearance between top
of unit and maximum 3 foot [.91 m] overhang.
3. Unit is design certified for application on combustible
flooring with 0" [0 mm] minimum clearance.
4. See Figure 6 for illustration of minimum installation-service clearances.
