Live Electrical
Components!
During installation, testing, servicing
and troubleshooting of this product,
it may be necessary to work with
live electrical components. Have a
qualified licensed electrician or other
individual who has been properly
trained in handling live electrical
components perform these tasks.
Failure to follow all electrical safety
precautions when exposed to live
electrical components could result in
death or serious injury.
6. Remove the factory installed
jumper or the field installed wiring
on terminals in the unit control
panel. This will prevent unwanted
chiller operation.
7. Set the purge operating mode to
OFF on UCP chillers.
8. The oil can be left in the unit.
9. The water side should not cause a
problem if shut down and drained.
There may be slight scaling inside
the tubes, but not enough to cause
a problem. The customer should
inspect and clean tubes before the
unit is returned to service.
IMPORTANT: DO NOT USE
UNTREATED OR IMPROPERLY
TREATED WATER, OR EQUIPMENT
DAMAGE MAY OCCUR.
IMPORTANT: SCALE DEPOSITS ARE
BEST REMOVED BY CHEMICAL
MEANS. BE SURE TO CONSULT
ANY QUALIFIED CHEMICAL HOUSE
IN THE AREA (ONE FAMILIAR WITH
THE LOCAL WATER SUPPLY’S
CHEMICAL MINERAL CONTENT)
FOR A RECOMMENDED CLEANING
SOLUTION SUITABLE FOR THE
JOB.
10. Motor bearings: If the motor sits
for a long time the bearings
could take a set and cause
bearing problems or replacement
later. Once every six months the
chiller oil pump must be started
and the compressor motor bump
started to rotate the shaft. Contact
a qualified service organization to
perform this task. If the
compressor motor cannot be
bump started, then the shaft must
be rotated manually by a
qualified service organization.
11. Obtain an oil analysis initially
after six months of storage, and
once each succeeding year. If no
oil breakdown is evident do not
change the oil. If breakdown is
evident, the oil must be replaced.
12. If the unit is stored for more than
five years, and the storage is
expected to be indefinite, the unit
should be examined for leaks
every five years from the initial
storage date.
13. When the unit is to be returned to
service, the services of a qualified
service organization should be
obtained to conduct all activities
associated with the startup of a
new chiller.
