Several different types of protective coatings are offered in some areas. These coat-
ings 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 Heat Pump is available without auxiliary heat or with 20, 40, 60 or 75
kW electric heat. Cooling and heating capacity of 15 nominal tons is available. Units
are convertible from bottom supply and return to horizontal supply and return by relo-
cation of supply and return air access panels. See cover installation detail.

The units are weatherized for mounting outside of the building.

B. MAJOR COMPONENTS

The unit includes a hermetically-sealed refrigerating system (consisting of compres-
sors, condenser coil, evaporator coil, biflow thermal expansion valves and reversing
valves), a circulation air blower, condenser fans, and all necessary internal electrical
wiring. The cooling system of these units is factory-evacuated, charged and perform-
ance 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 safe-
ly 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.
