Pre-Installation
ASHRAE Standard 15 Compliance
Trane recommends that indoor CenTraVac unit installa-
tions fully meet or exceed the guidelines of the current
version of ASHRAE Standard 15, in addition to any appli-
cable local, state, or national requirements. This typically
includes:
•
A refrigerant monitor or detector that is capable of
monitoring and alarming within the acceptable ex-
posure level of the refrigerant, and that can actuate
mechanical ventilation.
•
Audible and visual alarms, activated by the refriger-
ant monitor, inside the equipment room and outside
of every entrance.
•
The equipment room should be properly vented to
the outdoors, using mechanical ventilation that can
be activated by the refrigerant monitor.
•
The purge discharge and relief valves must be prop-
erly piped to the outdoors.
•
If required by local or other codes, a self-contained
breathing apparatus should be available in close
proximity to the equipment room.
Refer to the latest copy of ASHRAE Standard 15 for
specific guidelines. Trane assumes no responsibility for
any economic, health, or environmental issues that may
result from an equipment room’s design or function.
Unit Shipment
Inspect unit while it is still on the truck for any shipping
damage.
The chiller ships shrink-wrapped in a 0.254 mm (0.010-
in.) recyclable film protective covering. Do not remove
shrink-wrap for inspection! Inspect for damage to the
shrink-wrap and determine if physical damage has oc-
curred.
Each chiller ships from the factory as a hermetically
assembled package; it is factory piped, wired and test-
ed. All openings except for the waterbox vent and drain
holes are covered or plugged to prevent contamination
during shipment and handling.

an illustration of a typical unit and its components. As
soon as the unit arrives at the job site, inspect it thor-
oughly for damage and material shortages. In addition:
1. Verify the hermetic integrity of the unit by checking
the evaporator pressure for an indication of holding
charge pressure.
2. To prevent damaging moisture from entering the
unit and causing corrosion, each chiller is pressurized
with 3 to 5 psig of dry nitrogen before shipment.
Note:
The holding charge should register approximately
5 psig (34.5 kPa) at 72°F (22.2°C). Place a gauge
on access valve to verify. This access valve is
located on the front of the oil tank, which is at the
right rear corner of the chiller. If the charge has
escaped, contact your local Trane sales office for
instructions.
3. The loose parts box and isolator pads ship on top of
the control panel box.
4. Check the oil sump sight glasses to verify that the
oil level should be visible in the lower sight glass. If
no oil level is visible, contact your local Trane sales
office.
General Information
Regulations regarding waste handling are constantly
changing. To ensure that personnel are in compliance
with the latest federal, state and local regulations, con-
tact your local waste management office for the proper
procedures on handling, disposal, transporting and stor-
age of oil, oil filters, refrigerant filters, and filter dryer
cores.
