TIONS

RECEIVING AND INSPECTION

Immediately upon receiving shipment, equipment should be inspected for evidence of any damage received in
transit. If shipping damage has occurred, a claim should be made with the transportation company, and your
equipment representative should be advised of the nature of the damage.
Equipment should be inspected for compliance with original order acknowledgment (equipment model numbers,
voltage, refrigerant, etc.).

SETTING EQUIPMENT

When choosing a location for chiller, the following items should be considered:
a.) Front and sides of chiller have available service area.
b.) Electrical enclosure is visible for viewing alarm/indicator lights.
c.) Chiller should be located as close to process cooling application as possible.
d.) Availability of electrical power.
e.) Availability of city (well) water for water cooled condensing. (As applicable)
f.) Adequate air ow for air cooled condensing.
obstruction
g.) Level surface to mount unit.

PIPING

1. All piping must be in accordance with applicable local and state codes.
2. Refrigerant piping should be designed and installed in accordance with recommended practices outlined in ARI
or ASHRAE piping guide.
3. Water piping (for water cooled condensers) should be installed to meet application requirements. Keep in mind
that condenser barrels may need to be cleaned, all piping should have unions to enable end cap to be removed
from condenser. Any piping exposed to freezing ambient conditions should be insulated.
4. Water piping (chilled water) should be installed to meet application requirements. Properly size chilled water
process piping to insure that ow is not restricted due to extreme line pressure. It is recommended that chilled
water piping be ran in either of the following materials: industrial ABS, copper, or stainless steel. It is not advised
to run chilled water piping in galvanized or black-ironpipe (unless you are using a glycol with rust inhibitors), the
propylene glycol will erode the pipe and could also cause bacteria problems. Glycol piping should be insulated to
prevent condensation.
5. Check all chilled cooling application process piping for leaks prior to adding glycol solution.
6. Circulate water (without glycol) through process piping system and check for leaks.
e condenser must be at least 48" away from any
