Pre-Installation
ASHRAE Standard 15
Compliance
Trane recommends that indoor CenTraVac™ chiller
installations fully meet or exceed the guidelines of the
current version of ASHRAE® Standard 15, in addition to
any applicable national, state, or local requirements. This
typically includes:
• A refrigerant monitor or detector that is capable of
monitoring and alarming within the acceptable
exposure level of the refrigerant, and that can actuate
mechanical ventilation.
• Audible and visual alarms, activated by the refrigerant
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 the rupture disk must be
properly 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 0.010-in.
(0.254 mm) recyclable film protective covering. Do NOT
remove shrink-wrap for inspection! Inspect for damage to
the shrink-wrap and determine if physical damage has
occurred.
Each chiller ships from the factory as a hermetically
assembled package; it is factory-assembled, -wired, and
-tested. All openings except for the waterbox vent and
drain holes are covered or plugged to prevent
contamination during shipment and handling.“Unit
Components,” p. 14 shows 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 hermetic integrity of the unit by checking the
chiller 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 (20.7 to 34.5 kPaG) of dry nitrogen before
shipment.
Note: The holding charge should register approximately
5 psig (34.5 kPaG) at 72°F (22.2°C). Place a gauge
on the access valve provided (indicated by arrow
and circle in the following figure) on the refrigerant
pump discharge line to verify the holding charge. 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 sump
was factory-charged with 9 gallons (34.1 L) of oil. If no
oil level is visible, contact your local Trane sales office.
Important: If isolation springs are installed, do NOT block
oil tank serviceability.

Installation Requirements and
Contractor Responsibilities
A list of the contractor responsibilities typically associated
with the unit installation process is provided in the following
table.
WARNING
Combustible Material!
Failure to follow instructions below could result in
death , serious injury, or equipment damage.
Shrink-wrap is a combustible material. Avoid open
flames and hot sparks.
Note: The chiller should remain within its protective shrink-
wrap covering during storage.
