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.
