NOTE:
The circuit breaker located on the rear of the unit must be kept clear and easily
accessible.
To move the chiller, cap all ports to prevent any coolant leakage. Unlock the casters and move to new
location. Once in the new location lock the casters. To prevent freezing during storage drain water if
the chiller is located in an area below (10

C 50

F).
Plumbing the Coolant Lines
The coolant ports are located on the rear of the system and are labeled with the Supply
and Return symbols.

To minimize the pressure loss in the coolant lines, use the largest practical diameter tubing. If
substantial lengths of cooling lines are required, they should be pre-filled with coolant before
connecting them to the chiller.

To minimize heat gain, all lines should be as short as possible. Keep them away from heat
sources such as radiators and hot water pipes. Lines that cannot be routed away from heat
sources should be protected with thermal insulation, preferably at least 1/2" (12.7mm).

Flexible tubing, should be of heavy wall or reinforced construction. All tubing should be rated
to withstand 125 psig at 186
o
F (30
o
C). Make sure all tubing connections are secured and leak-
tight. Also, whenever possible use opaque lines to prevent algae growth during prolonged non-
operating periods.
**** CAUTION****
Do not connect the SUPPLY or RETURN fitting to your building water supply or any
pressurized source.
Installation Procedure
To connect the fluid lines to the chiller and user equipment follow these steps:
1. Remove the plastic caps covering the supply and return ports on the rear panel of the unit.
2. Attach coolant lines to the supply and return ports on the rear panel.

Supply port: chilled coolant goes out to user equipment

Return port: hot coolant returns from user equipment
