Trane RTHD

RTHD-SVX01D-EN 21
Installation Mechanical
NOTE: Maximum clearances are given. Depending on the unit configu-
ration, some units may require less clearance than others in the same
category.
Ventilation
The unit produces heat even though the compressor is cooled by the refriger-
ant. Make provisions to remove heat generated by unit operation from the
equipment room. Ventilation must be adequate to maintain an ambient tem-
perature lower than 122
o
F (50
o
C).
Vent the evaporator, condenser and compressor pressure relief valves in
accordance with all local and national codes. Refer to Table 11.
Make provisions in the equipment room to keep the chiller from being
exposed to freezing temperatures (32
o
F/0
o
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 con-
nections. Refer to “Water Piping.” All local and national codes apply.
Access Restrictions
Door clearances for the RTHD units are given in Figure 5. Refer to the unit
submittals for specific “per unit” dimensional information.
Moving and Rigging
The Model RTHD chiller should be moved by lifting at designated lift points
only. Refer to Figure 6 and Table 7 for typical unit lifting and operating
weights. Refer to the rigging diagram that ships with each unit for specific
“per unit” weight data.
 WARNING
Heavy Equipment!
Always use lifting equipment with a capacity exceeding unit
lifting weight by an adequate safety factor. (+10%). Follow the
procedures and diagrams in this manual and in the submittal.
Failure to do so can result in death or serious injury.
