Trane CVGF500 Installation, Operation & Maintenance Manual page 50

Installation: Mechanical
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 con-
denser water pass information. All measurement are in either US or metric equiva-
lents.
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 largecapacity drain for water vessel drain-down during shut-
down 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.
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 propertyonly 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%).
