General Information
Operating Environment
Besides assuring that the site
selected for chiller installation
provides the necessary clearances,
consider the equipment’s operating
environment.
To assure that electrical components
operate properly, do not locate the
chiller in an area exposed to dust,
dirt, corrosive fumes, or excessive
hear and humidity. Note that the
maximum ambient temperature
range for chiller operation to 100°F
[38°C].
CAUTION
Electrical Component
Damage!
Chiller operation at ambient
temperatures exceeding 100°F
(38°C) may result in starter or
electrical component damage. The
higher ambient temperatures may
affect the ability of panels to
dissipate heat.
Take whatever action is necessary to
improve the equipment room
environment if any of these adverse
operating condition are present.
Storage Requirements if
Chiller is not installed
1. Store the chiller in a dry, vibration
free and secure area on a solid
foundation. If the chiller has
factory installed insulation, protect
the chiller from direct sunlight. Do
not remove any of the factory
installed protective coverings.
6. The water side of the chiller
requires no special attention but
there may be slight scale build-up
inside the tubes. Tubes should be
inspected and cleaned before the
unit is placed into service.
7. If the motor sits for a long time,
the bearings could take a set and
cause bearing problems/
replacement later. Once every six
months the chiller oil pump must
be started and the compressor
shaft rotated 450 degrees. Contact
a qualified service organization to
perform this task.
8. If the chiller is stored for more
than five years, and the storage is
expected to be indefinite, the
chiller should be examined for
leaks every five years from the
initial storage date. Contact a
qualified service organization to
perform this task.
9. When the unit is to be installed,
follow instruction manuals that
were shipped with the chiller. The
services of a qualified service
organization should be obtained to
conduct all activities associated
with the start-up of a new chiller.
2. Do not charge the chiller with
refrigerant. If the refrigerant is at
the site, follow the refrigerant
manufacture’s instructions for
refrigerant charge.
3. A dry nitrogen holding charge of 3
to 5 psig [21 to 34.5kPa] was
installed at the factory. This
positive pressure must be checked
monthly to insure that moisture
and non- condensibles do not get
into the chiller. Check the pressure
gauge on the evaporator shell to
verify that the dry nitrogen holding
charge is still in the chiller. If this
charge had escaped, contact a
qualified service organization to
leak test and repair as necessary
and also notify the Trane sales
engineer that handled the order.
4. Do not operate the purge unit on
the chiller.
5. The oil can be left in the chiller if
an oil analysis is initially obtained
after six months, and once each
succeeding year. If no oil
breakdown is evident you do not
have to change oil. If breakdown is
evident, the oil will need to be
replaced. If an oil analysis
program is not followed,
discarded, and new oil installed
just prior to start-up by a qualified
service organization.
