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. Use shims as necessary to level the unit.
Isolators
The RTWA, RTUA and RTAC units should use neoprene isolators. Install
isolators at each unit mounting point.
Neoprene Isolator Installation.
Install the optional neoprene isolators at each mounting location. Isolators are
identified by part number and color.
1. Secure the isolators to the mounting surface, using the mounting slots in
the isolator base plate, as shown in Figure 12, 13 and 14. 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.
NOTE: RTWA/RTUA mount front isolators on cross rails not long rails for
best performance.
3. Lower the unit on to the isolators and secure the isolator to the unit with
a nut. Maximum isolator deflection should be approximately 1/4”.
4. Level the unit carefully. Refer to “Leveling”. Fully tighten the isolator
mounting bolts.
