This Installation, Operation, and Maintenance manual
applies to CenTraVac™ chillers with two different
refrigerant and compressor oil systems:
• R-123 refrigerant and OIL00022 compressor oil
• R-514A refrigerant and Trane OIL00379/OIL00380
compressor oil
I I m m p p o o r r t t a a n n t t : : Verify proper refrigerant and
compressor oil for your chiller before
proceeding!
CTV-SVX06J-EN
N N o o t t e e : : This manual applies to model CDHF, CDHG,
CVHE, CVHF, CVHG, CVHL, CVHM, and CVHS
CenTraVac chillers.
The Trane RuptureGuard™ refrigerant containment
system replaces the carbon rupture disk on chillers.
The RuptureGuard™ consists of a solid-metal, (non-
fragmenting) reverse-buckling rupture disk and
automatically re-seating relief valve with selectable
inlet and outlet adapter flanges. The relief valve and the
rupture disk are rated at the chiller's maximum working
pressure level. If the chiller's refrigerant pressure
exceeds the rupture disk burst rating, the disk bursts,
releasing pressure to the relief valve. The relief valve
vents the pressure down to a safe level and then re-
seats, thus minimizing the amount of refrigerant
vented to the atmosphere. The following figure
illustrates the operation of a reverse buckling rupture
disk. For more information on unit operation, refer to
"Operation," p. 22.

Receiving

Upon receipt of the unit, inspect the shipping crate for
signs of visible damage. Report any damage or
shortage to the carrier and note it on the delivery
receipt.
Unit must be stored in its original shipping crate in a
dry, secure place prior to its installation and use.
The disk snaps
open through
the score line of
the outlet ring
and the pressure
is vented. The
outlet ring is
designed with a
hinge area to
retain the disk
petal.
