Check the unit model number, electrical characteristics, and accessories to determine if
they are correct.

IV. SPECIFICATIONS

A. GENERAL

The Packaged Air Conditioner is available without heat or with 6, 10, 12, 15, 20 or 24
kW electric heat. Cooling capacities of 3, 3
able. Units are convertible from end supply and return to bottom supply and return by
relocation of supply and return air access panels. See cover installation detail.

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. The following information is for three phase units which are not covered
under the DOE certification program.

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 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.

1

⁄2 , 4 and 5 nominal tons of cooling are avail-

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.
3

• 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

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 R-410A equipment.

V. 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 contaminents 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.

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.

ILL I309

B. OUTSIDE SLAB INSTALLATION

(Typical outdoor slab installations are shown in Figures 5 and 6.)

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.

6. Remove compressor shipping supports (if so equipped) after installation.

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, 2800 Shirlington Road,
Suite 300, Arlington, VA 22206, http://www.acca.org.

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" 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.

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. Noncombustible flexible connectors should be used between ductwork and unit to
reduce noise and vibration transmission into the ductwork.

2. When auxiliary heaters are installed, use noncombustible flexible connectors and
clearance to combustible material of 0" for the first 3 feet of discharge duct.
Clearance to unit top and side is 0".

THE UNIT MUST BE PERMANENTLY GROUNDED. A GROUNDING LUG IS
PROVIDED IN THE ELECTRIC HEAT KIT ACCESS AREA FOR A GROUND
WIRE. FAILURE TO GROUND THIS UNIT CAN RESULT IN FIRE OR ELECTRI­CAL SHOCK CAUSING PROPERTY DAMAGE, SEVERE PERSONAL INJURY OR
DEATH.

F. THERMOSTAT

The thermostat should be mounted on an inside wall about five feet above the floor
in a location where it will not be affected by unconditioned air, sun, or drafts from
open doors or other sources. READ installation instructions in thermostat package
CAREFULLY because each has some different wiring requirements.

XII. INDOOR AIR FLOW DATA

Direct-drive blower models are shipped factory wired for the proper speed at a typical
external static. See Blower Performance Data. Belt-drive blower models have motor
sheaves set for proper CFM at a typical external static.

XIII.CRANKCASE HEAT (OPTIONAL)

Crankcase heat is not required on scroll type compressors, but may be necessary for
difficult starting situations.

XIV.PRE-START CHECK

1. Is unit properly located and slightly slanted toward indoor condensate drain?

2. Is ductwork insulated, weatherproofed, with proper spacing to combustible materi­als?

3. Is air free to travel to and from outdoor coil? (See Figure 5.)

4. Is the wiring correct, tight, and according to unit wiring diagram?

5. Is unit grounded?

6. Are field supplied air filters in place and clean?

7. Do the outdoor fan and indoor blower turn freely without rubbing, and are they tight
on the motor shafts?

8. Are the compressor shipping supports removed (if so equipped)?

XV. STARTUP

1. Turn thermostat to “OFF,” turn “on” power supply at disconnect switch.

2. Turn temperature setting as high as it will go.

3. Turn fan switch to “ON.”

4. Indoor blower should run. Be sure it is running in the right direction.

5. Turn fan switch to “AUTO.” Turn system switch to “COOL” and turn temperature set­ting below room temperature. Unit should run in cooling mode.

6. Is outdoor fan operating correctly in the right direction?

7. Is compressor running correctly.

8. Check the refrigerant charge using the instructions located on compressor access
panel. Replace service port caps. Service port cores are for system access only and
will leak if not tightly capped.

9. Turn thermostat system switch to proper mode “HEAT” or “COOl” and set thermostat
to proper temperature setting. Record the following after the unit has run some time.
A. Operating Mode _______________________________

10. Adjust discharge air grilles and balance system.

11. Check ducts for condensation and air leaks.

12. Check unit for tubing and sheet metal rattles.

13. Instruct the owner on operation and maintenance.

14. Leave “INSTALLATION” and ”USE AND CARE“ instructions with owner.

14

XVI.OPERATION

Most single phase units are operated PSC (no start relay or start capacitor). It is impor­tant that such systems be off for a minimum of 5 minutes before restarting to allow
equalization of pressures. The thermostat should not be moved to cycle unit without
waiting five minutes. To do so may cause the compressor to stop on an automatic open
overload device or blow a fuse. Poor electrical service can cause nuisance tripping in
overloads or blow fuses.

IMPORTANT: The compressor has an internal overload protector. Under some condi­tions, it can take up to 2 hours for this overload to reset. Make sure overload has had
time to reset before condemning the compressor.

Some units are equipped with a time delay control (TDC1). The control allows the blower
to operate for up to 60 seconds after the thermostat is satisfied.
