requirement for the chiller is a level surface capable of
bearing the combined operating weight of the modules
(See Physical Data on page 4).
Service Access
The recommended service clearances are 36” for front
access, 18” height clearance for 30, 50 and 70 ton modules,
and 24” height clearance for 85 ton module, 30” for rear
access and at least 12” for side clearance or as required for

require additional clearance – consult applicable codes.

ClimaCool recommends locking down the chiller to a
concrete base or to three (3) 4” base mounting rails using
the six (6) bolt holes provided in each base pan. Although
the compressors are installed on anti-vibration mountings,
further isolation of the chiller from the structure is
recommended by installing vibration-eliminating springs
or pads under the base rails on which the chiller will rest
(See Mounting Rail and Vibration Isolation on page 8). One
(1) module should be chosen as the reference module and
carefully located.
Field installed mounting accessories are provided for
adjoining each module:
• Header grooved coupling kits containing six (6) grooved
couplings with gaskets
• Mounting hardware kit containing necessary bolts,
spacers, nuts and washers
• Header bank end cap kit containing six (6) grooved
couplings with gaskets and six (6) end caps
Field installing the mounting hardware kit will assist with

inconsistencies. The 1/2” mounting holes are provided on
sides of the unit base pan. First module should be set, set
adjacent unit on mounting surface roughly aligned 1 ½ inches

and insert bolt through front mounting hole and spacer.
Repeat the process for the rear mounting hole. Line up
mounting hole of adjacent module with bolt from previous
module and working through adjacent modules front base
cutout place a washer, split lock washer and nut. Using the
appropriate tools tighten hardware assembly until seated.
Inspect the pipe ends to ensure they are free from any
indentations, projections, roll marks or other harmful surface
defects such as loose paint, scale, dirt, chips, grease and rust.
Inspect the grooved coupling gasket for any defects. Apply
a thin layer of silicone or other non-petroleum lubricant to
the sealing lips of the gasket as well as to the exterior of the
gasket. Install gaskets on the pipe ends of one of the two
modules to be mated. ‡•—”‡–Š‡‰ƒ•‡–‹• ‘’Ž‡–‡Ž›‘
–Š‡’‹’‡•‘†ƒƒ‰‡™‹ŽŽ‘–‘ —”‹–Š‡‡š–•–‡’Ǥ Move the
second module into position and line up the piping. Ensure
you are maintaining alignment for any additional modules to
be added. When pipe ends are aligned, slide the gasket over
the ends and center it between the grooves. No part of the
gasket should protrude into the groove of either pipe end.
Place the coupling halves over the gasket and make sure that
the coupling keys (the part that goes into the groove), are
engaged into the grooves. Insert the bolts and install nuts
to hand tight. Ensure that the oval neck of the bolt engages
into the bolt hole of the housing. Tighten nuts alternately

Header Insulation
Chilled water piping is pre-insulated on each module at
the factory with ¾” closed cell insulation. After bolting
all modules together and leak testing, the entire coupling
connection needs to be insulated by the installing contractor.
Sound Attenuation Panels and Gasket
Attenuation panels are enclosures made of 18 gauge

insulation. Field installed panel package includes two (2)
upper panels and one (1) lower panel for each side of bank
for both SHC heat pump and heat recovery models. Factory
installed panels include:
• Heat Pump 30, 50, 70Ton – four (4) front and back
panels and one (1) top cap made up of four (4) panels
• Heat Pump 85Ton - four (4) front and back panels and

• Heat Recovery 85Ton - four (4) front and back panels
and two (2) top cap made up of eight (8) panels
Install panels by setting in place and locking down with the
half turn latches or with self-tapping screw. Note: Panel
