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 dam-
age, either shipping or concealed, should be filed immediately with the shipping com -
pany. 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 and 17.5 tons.
300,000 and 400,000 BTUH heating inputs are available in nominal cooling capacity
of 20 and 25 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 and 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 perfor-
mance 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.
