Unit Shipment
Each chiller ships from the factory as
a hermetically assembled package; it
is factory piped, wired and tested. All
openings are covered or plugged to
prevent contamination during
shipment and handling.
See Figure 2 for an illustration of a
typical unit and its components. As
soon as the unit arrives at the job
site, inspect it thoroughly for
damage and material shortages. In
addition:
1. Verify the chiller's hermetic
integrity by checking the
evaporator pressure for an
indication of holding charge
pressure.
Note: Since there are two refrigerant
circuits both must be checked.

General Information
To prevent damaging moisture from
entering the unit and causing
corrosion, each chiller is pressurized
with dry nitrogen before shipment.
Note: The holding charge should
register approximately 5 psig (at sea
level) on the gauge. If the charge has
escaped, contact your local Trane
sales office for instructions.
2. Check the oil sump sight glasses
to verify that the sump was
factory-charged with 9 gallons of
oil. If no oil level is visible, contact
your local Trane sales office.
3. Compare the unit nameplate data
(including electrical characteristics)
with the corresponding ordering
and shipping information to verify
that the correct unit was shipped
to the job site.
If a thorough inspection of the
chiller reveals damage or material
shortages, be sure to file these
claims with the carrier
immediately. Specify the extent
and type of damage found, and
notify the appropriate Trane sales
representative. Do not install a
damaged unit without the sales
representative's approval!
Storage
If the chiller will be stored at the job
site for an extended period of time
before it is installed, exercise these
precautionary measures to protect
the unit from damage:
1. Do not remove the protective
coverings factory-installed on the
control panel and compressor
inlet vane actuator for shipment.
2. Store the chiller in a dry vibration
free and secure area. If factory
insulated, protect chiller from
prolonged exposure to sunlight.
CAUTION
Insulation Damage!
To prevent damage to the factory-
installed insulation, do not allow
excessive exposure to sunlight.
3. Periodically check the condenser
and evaporator pressure to verify
that the 5 psig dry nitrogen at 72°F
ambient holding charge is still in
the chiller. If this charge escapes,
contact a qualified service
organization and the Trane sales
engineer that handled the order.
Note: The storage range for the
microcomputer-based devices in the
unit control panel is -40°F to 158°F
(-40°C to 70°C).
