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.

VII. DUCTWORK
Ductwork should be fabricated by the installing contractor in
accordance with local codes and NFPA90A. Industry manuals
may be used as a guide when sizing and designing the duct
system - contact Air Conditioning Contractors of America, 1513
16th St. N.W., Washington, D.C. 20036.
WARNING
!
DO NOT, UNDE R AN Y CIR CUMS T ANCE S, C ONNE C T
RETURN DUCTWORK TO ANY OTHER HEAT PRODUCING
DEVICE SUCH AS A FIREPLACE INSERT, STOVE, ETC.
UNAUTHORIZED USE OF SUCH DEVICES MAY RESULT IN
FIRE, CAR BON MONOXIDE POISONI NG, EXPLOSION,
PROPERTY DAMAGE, SEVERE PERSONAL INJURY OR
DEATH.
The unit should be placed as close to the space to be air conditioned as possible allowing clearance dimensions as indicated.
Ducts should be run 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. A slab installation could be considered 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" [50.8 mm] of insulation and
a vapor barrier. Distribution system in attic, furred space or
crawl space should be insulated with at least 2" [50.8 mm] of
insulation with vapor barrier. One-half to 1" [25.4 mm] thickness of insulation is usually sufficient for ductwork inside the air
conditioned space.
Balancing dampers should be provided for each branch duct in
the supply system. Ductwork should be properly supported
from the structure.
When installing ductwork, consider the following items:
1. Nonc ombu s tibl e fle xible conn ector s sho uld be us ed
between ductwork and unit to reduce noise and vibration
transmission into the ductwork.
2. When auxiliary heaters are installed, use noncombustible
lexible connectors and clearance to combustible material
f
of 0" [0 mm] for the first 3 feet [.91 m] of discharge duct.
Clearance to unit top and side is 0" [0 mm].
VIII. FILTERS
This unit is provided with 6 - 2" x 18" x 18" [51mm x 457 mm x
457 mm] disposable filters. When replacing filters, ensure they
are inserted fully to the back to prevent bypass.
VIX. CONVERSION PROCEDURE

XVI. OPERATION
COOLING MODE
With thermostat in the cool mode, fan auto and the room temperature higher than the thermostat setting:
A. Indoor blower contactor is energized through thermostat
contact (G).
B. Compressor contactors are energized through thermostat
contacts (Y1) & (Y2) and high pressure controls.
C. Economizer enthalpy control (if installed) controls operation
of first-stage cooling and positions fresh air damper to maintain mixed air temperature. Second-stage cooling operates
normally as required by second stage of thermostats.
. The system will continue in cooling operation as long as all
D
safety controls are closed, until the thermostat is satisfied.
HEATING MODE
With the thermostat in heat mode, fan on auto, and the room
temperature lower than the thermostat setting, the Indoor
blower contactor is energized through thermostat contact (G).
