General Information
Recommended Unit
Clearances
Adequate clearance around and
above the chiller is required to allow
sufficient access for service and
maintenance operations.
Figure 3 illustrates the
recommended clearances for units
with and without options. Figure 4
shows tube bundle locations. Notice
that, in each instance, the minimum
vertical clearance above the chiller is
3-feet.
In addition, be sure to provide at
least 3-feet of working space in front
of the unit control panel to satisfy the
National Electrical Code, and/or local
codes.
Important! Do not install piping or
conduit above the compressor
motor assembly or behind the
suction elbow!
Note: Specific unit clearance
requirements are also indicated in
the submittal package provided for
your unit.
Operating Environment
Besides assuring that the site
selected for chiller installation
provides the necessary clearances,
consider the equipment’s operating
environment.
To assure that electrical components
operate properly, do not locate the
chiller in an area exposed to dust,
dirt, corrosive fumes, or excessive
heat and humidity. Note that the
maximum ambient temperature for
chiller operation is 95 to 100°F (35° -
38° C).
CAUTION
Equipment Failure!
CDHF operation at ambient
temperatures exceeding 100°F
(38°C) can fatigue the unit’s rupture
disc, causing it to break at a reduced
refrigerant pressure (i.e., <15 psig).
Starter component damage can also
occur because of the panel’s inability
to dissipate heat adequately.
If any of these adverse operating
conditions are present, take
whatever action is necessary to
improve the equipment room
environment.
Foundation Requirements
Provide rigid, non-warping
mounting pads or a concrete
foundation as a mounting surface for
the chiller. Ensure that the base is of
sufficient strength and mass to
properly support the chiller at its full
operating weight (i.e., including
completed piping, and full operating
charges of refrigerant, oil and water).
For your convenience, a summary of
standard unit shipping and operating
weights is provided in Table 2.
Notice that the floor loading for all
sizes of chillers is 60 pounds per
square inch.
To assure proper unit operation, the
chiller must be level within 1/16”
over its length and width when set
into place on the mounting surface.
Trane will not assume responsibility
for equipment problems resulting
from an improperly designed or
constructed foundation.
