Mounting and Placement
Mounting Options
When installing any floor mounted unit, some form of
vibration isolation is required
The EZ-Fit cabinet has one (single) or two (dual) modules
Each module has three or more cabinet sections The EZ-
Fit requires support on the corners, the middle of each
section, and wherever sections come together If the entire
cabinet base of each section is not supported, refrigeration
pipe breakage and/or coil leaks will occur, and the warranty
coverage will be void
Cabinet Vibration Isolation Method
Options:
One of the following recommended cabinet vibration
isolation methods are required and must be provided by
the field Keep in mind that sufficient height of the cabinet
vibration isolation must account for the required height of
the condensate drain trap
1 Steel Frame with Spring Isolation – Fabricate a steel
frame to provide support around the entire perimeter
of the unit Allow sufficient clearance for any door or
panel access that is required to provide field service or
maintenance on the unit The frame will also need to be
designed with suitable cross bracing See Figure 3B and
notice that the middle beam supports the mid-section of
the unit Field supplied spring vibration isolators are to
be installed on each corner of each frame per module
2 Channel Steel with Waffle Pads - Obtain channel steel
rail of an approved gauge to support the unit weight
and place underneath the unit in 4 locations per single
module or 7 locations per dual module, see Figure 3C
Place waffle pad type furnace pads underneath the
channel steel rail inside the “C” facing down for sound
dampening It is important that the channel steel rail
does not touch the ground or sound dampening will not
occur All the rails must be level before placing the unit
atop them Please note the locations of the pads
3 Waffle Pads Only - If cabinet height prevents adequate
space for framing, waffle pads alone may be used,
reference Figure 3E It is highly recommended that each
IMPORTANT
The assembled EZ-Fit cabinet has not
been designed for corner point only
loading with vibration isolators
pad be of identical height and that the pads are kept no
smaller than 4”x 4” You will need at minimum 30 pads to
support the EZ-Fit properly Additional pads, more than
the specified count, will improve the support of the unit
The goal is to keep the middle of the unit from sagging
Support under the compressors and water coils is key
