Installation
PRGF-SVN001B-EN 11
Mounting Procedure
CAUTION
Heavy Objects!
Proper lifting equipment must be present to remove the
existing purge and mount the EarthWise™ purge. Use
of a step ladder may be necessary. Failure to follow
these safety procedures may result in minor injury or
equipment damage.
Purge
The EarthWise purge unit is mounted on an integral base
as shipped. Mount the purge unit on the mounting
brackets, using four (4) 1/4-20 thread-forming screws
(brackets and screws provided in conversion kit).
Position the purge assembly at the proper mounting
location and weld the brackets to the upper surface of the
chiller’s highest condenser.
Note: If the mounting brackets provided in the
conversion kit cannot be used, it will be necessary
to fabricate custom brackets to mount the purge on
the condenser.
Important: Always check chiller model number and
condenser nameplate to determine if
condenser is an ASME-coded vessel. If it is,
all applicable ASME and local codes
concerning repairs to coded vessels must
be observed.
Human Interface
The human interface ships separate from the purge unit. It
can be removed and relocated elsewhere on the chiller or
to another convenient location near the chiller. See
Figure 7 .
The Aftermarket purge requires the refrigerant type to be
set manually through the human interface (DynaView).
To change the refrigerant type in the human interface
(DynaView), follow the steps below:
1. Select the “Settings” tab.
2. Select “Purge” from the menu.
3. Select “Refrigerant Type” from the menu.
4. Choose the correct refrigerant for your chiller.
5. Return to the previous menu and verify that the correct
refrigerant is shown for refrigerant type.
CAUTION
Equipment Damage!
The EarthWise purge unit must be configured to
accommodate R-11 refrigerant through the DynaView
when used with an R-11 chiller. Refer to the Human
Interface section of this manual. Failure to follow this
safety precaution could result in equipment-only
damage.
