III. INTRODUCTION
This booklet contains the installation and operating instructions for your package heat
pump. There are a few precautions that should be taken to derive maximum satisfaction
from it. Improper installation can result in unsatisfactory operation or dangerous condi-
tions.
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.
NOTE: A load calculation must be performed to properly determine the required heating
and cooling for the structure. Also, the duct must be properly designed and installed for
proper airflow. Existing dutwork must be inspected for proper size and sealed system.
Proper airflow is necessary for both user comfort and equipment performance.
IMPORTANT: Proper application, installation and maintenance of this equipment is a
must if consumers are to receiver the full benefit for which they have paid.
A. 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.
22. Recovery and recycle equipment, pumps, hoses and the like need to have design
Pressure: The pressure of R-410A is approximately 60% (1.6 times) greater than R-
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
pressure rating. DOT 4BA400 or DOT BW400.
service pressure rating of 800 psig. Recovery cylinders need to have a 400 psig service
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
be done with a mixture of R-410A and air. Leak checking can be performed safely
lines, or be allowed to accumulate in storage tanks. Leak checking should never
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.
• 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 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
