Installing the Unit
Installation of the new purge unit requires several wiring and hardware modifications. To
insure proper installation, it is important that the installer thoroughly read an d understand the
following instructions.
NOTE:
The installer should record all changes and modifications made to the chiller during
installation and provide a copy for inclusion with the maintenance records of the
chiller.
Location
The purge unit is not location sensitive. The only limitation is that it must be higher than the
liquid refrigerant level in the chiller evaporator . The unit may be located at any convenient
location on or near the chiller. If you are replacing an old unit, it can be locat ed in the same
place as the existing system.
Mounting
In a few cases, some fabrication may be necessary to mount the new purge. Since the purge
comes mounted on its own integral base, field fabrication should be minimal.
WARNING:
The purge weighs approximately 110 lbs. To avoid possible injury or
damage to equipment, be sure to have appropriate equipment available to raise the unit
into place.
