Installation
Initial Installation
The mounting location of the Purifier Plus™ canister is determined by:
1. The style of chiller
2. Chiller options such as free-cooling, hot gas bypass, etc.
3. Service access to the chiller and canister
It is recommended that it be securely mounted to the chiller, off the floor in a
dry, clean location. See Figure 2 for possible mounting locations on a CVHE-
style chiller.
1. Mount the canister in the holding bracket. The bracket has holes in both
the bottom and back plates for mounting directly to chiller leg (Figure 2,
Option 3). V-Brackets are included in the kit for mounting to the curved
surface of the condenser (Figure 2, Option 1 or 2). See Figure 6 for
dimensions.
2. Install 3/8” OD copper tube from the purge exhaust to the canister inlet.
(The inlet is in the center of the tank.) Install 3/8” OD copper tube from
the canister outlet to the chiller vent line. (See Figure 3).
3. Insure there are no restrictions in the exhaust line. If any valves are
included in the line, they must be fully open during use.
4. Install or modify the Change Purifier Plus Canister label (Figure 4) on the
Purifier Purge near the minute timer. Add the applicable value from Table
1 to the current value on the purge minute timer. Record this number on
line A. Add three years to the installation date and record on line B.
5. Record the requested information on the canister nameplate. (See Figure
5), including refrigerant type in appropriate check box.
Do not pressurize from an external
source. Pressurizing tank from an
external source could cause tank
to rupture, resulting in death or
serious injury.
WARNING
!
Before installation, verify the
refrigerant type marked on the
Purifier Plus canister is the same
as the refrigerant in the chiller. DO
NOT CONTAMINATE THE
CANISTER WITH THE WRONG
REFRIGERANT.
Caution:
!
The refrigerant must be evacuated
from the chiller before welding of
any kind is done to the condenser
shell.
