▲WARNING

!

UNITS ARE NOT DESIGN CERTIFIED
TO BE INSTALLED INSIDE THE
STRUCTURE. DOING SO CAN CAUSE
INADEQUATE UNIT PERFORMANCE
AS WELL AS PROPERTY DAMAGE
AND CARBON MONOXIDE POISON­ING RESULTING IN PERSONAL
INJURY OR DEATH.

CHECKING PRODUCT RECEIVED

This booklet contains the installation and operating instructions for your combination
gas heating/electric cooling unit. There are some 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.

EQUIPMENT PROTECTION FROM THE
ENVIRONMENT

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. IMPORTANT: Check the unit model number, heating size, electrical character-
istics, and accessories to determine if they are correct.

I. SPECIFICATIONS

A. GENERAL

The Combination Gas Heating/Electric Cooling Rooftop is available in 250,000 AND
350,000 BTUH heating input with nominal cooling capacity of 15 tons. 300,000 and
400,000 BTUH heating inputs are available in nominal cooling capacity of 20 tons.
Units are convertible from bottom supply and return to side supply and return by relo­cation of supply and return air cover panels. See cover installation detail and Figures
10 &11.

The units are weatherized for mounting outside of the building.

B. MAJOR COMPONENTS

The unit includes a hermetically-sealed refrigerating system consisting of a scroll
compressor, condenser coil, evaporator coil with capillary tube assembly or TXV, a
circulation air blower, condenser fans, a heat exchanger assembly, gas burner and
control assembly, combustion air motors and 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. R410A 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.

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/ Expansion Device

The capillary tubes are specifically designed to operate with R-410A. DO NOT use an R­22 expansion 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.

NOTES:

1. Cooling Performance is rated at 95° F ambient, 80° F entering dry bulb, 67° F entering wet bulb. Gross capacity does not include the effect of fan motor heat. AHRI capacity is net and includes
the effect of fan motor heat. Units are suitable for operation to 20% of nominal cfm. Units are certified in accordance with the Unitary Air Conditioner Equipment certification program, which is
based on AHRI Standard 210/240 or 360.

2. EER and/or SEER are rated at AHRI conditions and in accordance with DOE test procedures.

3. IEER is rated in accordance with AHRI standard 340/360.

4. Heating Performance limit settings and rating data were established and approved under laboratory test conditions using American National Standard Institute standards. Ratings shown are for
elevations up to 2000 feet. For elevations above 2000 feet, ratings should be reduced at the rate of 4% for each 1000 feet above sea level.

5. Outdoor Sound Rating shown is tested in accordance with AHRI Standard 270.

NOTES:

1. Cooling Performance is rated at 95° F ambient, 80° F entering dry bulb, 67° F entering wet bulb. Gross capacity does not include the effect of fan motor heat. AHRI capacity is net and includes
the effect of fan motor heat. Units are suitable for operation to 20% of nominal cfm. Units are certified in accordance with the Unitary Air Conditioner Equipment certification program, which is
based on AHRI Standard 210/240 or 360.

2. EER and/or SEER are rated at AHRI conditions and in accordance with DOE test procedures.

3. IEER is rated in accordance with AHRI standard 340/360.

4. Heating Performance limit settings and rating data were established and approved under laboratory test conditions using American National Standard Institute standards. Ratings shown are for
elevations up to 2000 feet. For elevations above 2000 feet, ratings should be reduced at the rate of 4% for each 1000 feet above sea level.

5. Outdoor Sound Rating shown is tested in accordance with AHRI Standard 270.

NOTES:

1. Cooling Performance is rated at 95° F ambient, 80° F entering dry bulb, 67° F entering wet bulb. Gross capacity does not include the effect of fan motor heat. AHRI capacity is net and includes
the effect of fan motor heat. Units are suitable for operation to 20% of nominal cfm. Units are certified in accordance with the Unitary Air Conditioner Equipment certification program, which is
based on AHRI Standard 210/240 or 360.

2. EER and/or SEER are rated at AHRI conditions and in accordance with DOE test procedures.

3. IEER is rated in accordance with AHRI standard 340/360.

4. Heating Performance limit settings and rating data were established and approved under laboratory test conditions using American National Standard Institute standards. Ratings shown are for
elevations up to 2000 feet. For elevations above 2000 feet, ratings should be reduced at the rate of 4% for each 1000 feet above sea level.

5. Outdoor Sound Rating shown is tested in accordance with AHRI Standard 270.
