Unit Isolation and Leveling
Mounting
Construct an isolated concrete pad for the unit or provide
concrete footings at each of the four unit mounting points.
Mount the unit directly to the concrete pads or footings.
Level the unit using the base rail as a reference.The unit
must be level within 1/4” over the entire length and width.
Use shims as necessary to level the unit.
Isolation Pads
Note: The elastomeric pads shipped (as standard) are
adequate for most installations. For additional
details on isolation practices, refer toTrane
Engineering Bulletin -Series R
®
Chiller Sound
Ratings and Installation Guide, or consult an
acoustical engineer for sound-sensitive
installations.
During final positioning of the unit, place the isolation
pads under the evaporator and condenser tube sheet
supports as shown in Figure 13, p. 33. Level the unit as
described in the next main paragraph.
Neoprene Isolator Installation (optional)
Install the optional neoprene isolators at each mounting
location. Isolators are identified by part number and color.
Refer to submittal drawing for correct isolators.
1. Secure the isolators to the mounting surface, using the
mounting slots in the isolator base plate, as shown in
Figure
. Do not fully tighten the isolator mounting bolts
at this time.
2. Align the mounting holes in the base of the unit, with
the threaded
positioning pins on the top of the isolators.
3. Lower the unit on to the isolators and secure the
isolator to the unit with a nut.
4. Level the unit carefully. Refer to “Leveling”. Fully
tighten the isolator mounting bolts.
