INSTALLATION
Before You Start
Caution:
Federal Refrigerant Recycling Regulations require that the chiller, during
servicing, be either completely evacuated or pressurized to atmospheric pressure (0
psig) prior to opening the refrigerant circuit to the atmosphere. Failure to comply, or
using means other than heat to elevate refrigerant pressure, violates Section 608 of the
Clean Air act.
The purge system is designed to automatically remove non-condensables from low pressure
centrifugal chillers using CFC or HCFC refrigerants. The Purge, together with the emission
collection canister, is designed to assure the highest efficiency in preventing refrigerant fr om
escaping to the atmosphere.
This section discusses the proper procedures for replacing the purge unit on an R -113 low
pressure centrifugal chiller. This purge unit is designed for application on water cooled
centrifugal chillers, either pneumatically or electrically controlled.
NOTE
: The Purge Unit is not designed for application on air cooled chillers.
Warning:
Installing or servicing refrigerant support equipment can be hazardous due
to system pressures and dangerous voltages. Only qualified serv ice personnel should
work on such equipment.
