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

II. INTRODUCTION

This booklet contains the installation and operating instructions for your air conditioner.
There are a few precautions that should be taken to derive 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 accessories to
determine if they are correct.

IV. EQUIPMENT PROTECTION FROM THE

IV. 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 Conditioners are available without heat or with 10, 15, 20, 30, 40 or
50 kW electric heat. Cooling capacities of 7.5, 10 or 12.5 nominal tons of cooling are
available. 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.

The units are weatherized for mounting outside of the building.

4

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 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 typical 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 are 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

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.

; equipment designs must

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 / Expansion Device
The expansion device is specifically designed to operate with R-410A. DO NOT use an

R-22 device. The existing evaporator must be replaced with the factory specified
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.
