This Installation, Operation, and Maintenance manual
applies to CenTraVac™ chillers with two different
refrigerant and oil systems:
• R-123 and OIL00022
• R-514A and OIL00334/OIL00335
I I m m p p o o r r t t a a n n t t : : Verify proper refrigerant and oil for your
chiller before proceeding!
The information and procedures in this document are
to facilitate unit disassembly for clearance and access
reasons during the installation process.
The understanding is that the chiller has what is
referred to as the "compressor doweling option" or
"separable shell option" (which includes compressor
doweling). Compressor doweling sets up the
compressor for removal. The separable shell option
includes a bolt together design between the evaporator
and condenser and allows the shells to be separated in
the field.
I I m m p p o o r r t t a a n n t t : : These procedures do NOT apply to units
that have been installed and electrical
supply wiring has been completed.
