Water Pipe Connections
Table 9 applies to all CVGF
chiller tonnage sizes 500, 700
and 1000.
Refer to Table 9 for water pipe
connection sizing information
and evaporator and condenser
water pass information. All
measurement are in either US
or metric equivalents.
Ventilation
The unit produces heat even
though the compressor is
cooled by the refrigerant. Make
provisions to remove heat
generated by unit operation
from the equipment room.
Ventilation must be adequate to
maintain an ambient
temperature lower than 122°F
(50°C).
Vent the unit pressure relief
valves in accordance with all
local and national codes.
Make provisions in the
equipment room to keep the
chiller from being exposed to
freezing temperatures of 32°F
(0°C).
Water Drainage
Locate the unit near a large-
capacity drain for water vessel
drain-down during shutdown or
repair. Condensers and
evaporators are provided with
drain connections. All local and
national codes apply.
Moving and Rigging
The Model CVGF chiller should
be moved by lifting at
designated lift points only. Refer
to the rigging diagram that ships
with each unit for specific per
unit weight data.

WARNING
Heavy Objects!
Do not use cables (chains or
slings) except as shown. Each of
the cables (chains or slings)
used to lift the unit must be
capable of supporting the entire
weight of the unit. Lifting cables
(chains or slings) may not be of
the same length. Adjust as
necessary for even unit lift.
Other lifting arrangements may
cause equipment or property-
only damage. Failure to properly
lift unit may result in death or
serious injury. See details
below:
• Follow the procedures and
diagrams in this manual and in
the submittal.
• Always use lifting equipment
with a capacity exceeding the
unit lifting weight by an
adequate safety factor. (+10%).
