Installation Mechanical
RTHD-SVX02H-EN 27
Note: Maximum clearances are given. Depending on
the unit configuration, 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 refrigerant. Make provisions to remove
heat generated by unit operation from the equipment
room. Ventilation must be adequate to maintain an ambi-
ent temperature lower than 122°F (50°C).
Vent the evaporator, condenser and compressor pres-
sure relief valves in accordance with all local and nation-
al codes. Refer to Table 12.
Make provisions in the equipment room to keep the
chiller from being exposed to freezing temperatures
(32°F/0°C).
Water Drainage
Locate the unit near a large capacity drain for water ves-
sel drain-down during shutdown or repair. Condensers
and evaporators are provided with drain connections.
Refer to “Water Piping.” All local and national codes ap-
ply.
Access Restrictions
Door clearances for the RTHD units are given in Figure
9 . 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 10 and Table
10 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.
