GENERAL INFORMATION
REGARDING DESIGN TEMPERATURE
Our custom chiller systems are designed to
maintain the temperature of cooling fluids within a
selected temperature range. Each of our units is
tested through monitored operation within design
parameters. This enables our experienced
technicians to calibrate all instrumentation
precisely to the customers needs and verify that
each individual unit will function as specified.
Supporting test data is enclosed either in digital
format or in print.
The units are designed to operate efficiently within
given parameters. Due to varying heat exchange
rates outside of design temperature, it is highly
recommended that the machine operate only at
temperatures within 10°F of the specified
temperature. Consult the factory if a process
requires changes in excess of 10°F in either
direction of design temperature.
INSTALLATION:
1. Read and follow all information included with
the chiller manual.
2. Read and understand all warning labels and
tags on the chiller before installation.
3. Ensure the unit is placed on a flat, level, hard
surface. Unless the chiller has been built for
outdoor operation, it must be placed indoors.
Space above and around the unit must be
capable of dissipating the heat rejected by the
chiller and allow room for servicing. Keep the
unit at least 3ft away from walls or other
objects and allow full access to all openings
and electrical enclosures. At a minimum, 8ft of
clearance is required above the unit for proper
air circulation around the chiller as shown in
Fig 1.
4. Chillers with solid feet should be secured using
the provided mounting holes if possible. Units
that have caster wheels should be locked to
ensure the chiller does not move around.

5. Connect fluid lines to the proper fittings from
the process to the chiller marked “FLUID INLET
TO CHILLER” and “FLUID OUTLET FROM
CHILLER”. Make sure that the flow of fluid to
and from the unit can not be shut off or
blocked while the chiller is in operation. Piping
size should be large enough to match the fluid
flow conditions, generally the size of the
fittings on the chiller.
6. Fill the process plumbing and, if applicable, the
chiller reservoir with the proper type and
amount of fluid. Check with the
manufacturer of the process equipment
for specific fluid requirements. Refer to
the “Process Fluid Recommendations”
section of the manual for information on
using water in the chiller.
7. Purge any air out of the fluid system to ensure
that the pump suction is flooded. If possible,
bleed any air trapped in the pump by opening
the vent plug at the top of the pump until no
more air comes out and fluid is present in the
pump cavity.
DO NOT ALLOW THE FLUID PUMP TO RUN DRY.
THIS WILL DAMAGE THE PUMP SEALS AND
WILL NOT BE COVERED UNDER WARRANTY.
8. Connect any communication wiring between
the chiller and process equipment including
remote controls and interlocks. All
communication and remote wiring is to be
provided by the customer. Refer to the chiller’s
electrical prints for information on wiring
locations.
