JOHNSON CONTROLS
FORM 145.05-NOM1 (708)
The unit base frame will accept dollies or Johnson bars
for transporting the unit. Furniture dollies can be placed
at both ends of the chassis or at one end, and a Johnson
bar used at the other end for maneuvering.
Do not attempt to install dollies in the
center of the unit. Units can become
unstable and tip over causing injury.
Do not use hooks to lift unit or hook
into open channels to lift unit. This
could cause unit damage.
FACTORY-SUPPLIED PLENUM
If the unit is provided with a factory plenum for field
mounting, a forklift, slings or other suitable lifting
means is required to position the plenum above the unit.
Prior to placing the plenum on the top of the unit verify
the foam rubber gasket is in place around the perimeter
of the unit top. Align the plenum front with the control
panel side of the unit. Carefully set the plenum and
attach using the mounting hardware provided with the
plenum. Treat field-cut holes to prevent fiberglass from
entering the air stream.
Do not remove more than two non-
adjacent panels at one time, failure
to do so will cause the plenum frame
to collapse and may cause personal
injury.
The plenum insulation strip must be
applied properly to prevent air bypass
around the plenum
VIBRATION ISOLATORS
Each Versecon unit includes 1-inch high vibration
isolation pads composed of 1/2 inch thick cork
sandwiched between ¼ inch thick neoprene pads.
The vibration isolators should be placed with the
2–inch width of the isolator supporting the 2-inch deep
frame.
For units with 6 pads (12, 16, 21, and 25 ton units) the
pad locations should be one near each of the corners and
one on the front and back of the unit near the center.
For units having more than six pads the pads should
be placed at each corner and then distributed evenly
between the front and back and sides. The 32 and 39
ton units have 8 pads, the 48 ton unit has 12 pads, the
55, 63, 73, 50, and 60 ton has 16 pads, the 72, 79, and
90 ton units have 20 pads.
SEGMENTED UNIT ASSEMBLY
For ease of handling and transport in a freight elevator
the Versecon product can be split and shipped in three
segments. The unit was assembled and tested at the
factory prior to shipment. The sections were then
separated for shipment. The three segments are as
follows:
•
Compressor / Condenser / Coil section
•
Control and supply air fan section
•
Filter or filter and hydronic heat section (op-
tional)
Refer to publication Form 145.05-FA1 for detailed
instruction on how to reassemble the unit.
