Unit Installation
Foundation for Unit Placement
The minimum foundation requirement for the ClimaCool
chiller is a level surface capable of bearing the combined
operating weight of the modules
(See Physical Data -
page 6).
Service Access
The recommended service clearances for front service
access is 42”, unobstructed height clearance for airfl ow
and 36” for rear service access as identifi ed in the
Recommended Service Clearances and Bank Dimensions on
page 10 and 11. Local building or electrical codes may require
additional clearance – please consult applicable codes.
Draining
When performing standard maintenance procedures such
as fl ushing a heat exchanger, it will be necessary to close
off a section of a module. ClimaCool modular chillers off er
optional water isolation valves for this purpose.
Assembling Modules
ClimaCool recommends locking down the chiller to a
concrete base, or to two 4” base mounting rails using
the bolt holes provided in the unit base. Although the
compressors are installed on anti-vibration mountings,
further isolation of the chiller from the structure is available
by installing vibration eliminating springs or pads under
the base rails on which the chiller will rest (See page 9 –
Mounting Rail and Vibration Isolation). One end of the
modules should be chosen as the reference module and
carefully located.
Mounting hardware kits, header grooved coupling kits and
groove by groove nipples are factory provided for adjoining
each module. Each hardware kit contains necessary bolts,
spacers, nuts and washers. The header grooved coupling
kit consists of two (2) grooved couplings and the groove by
groove nipple kit has two (2) 6” groove by groove nipples
with gaskets. In addition, there will be one header end cap
kit consisting of (2) grooved couplings with gasket and (2)
end caps.
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
and to the exterior of the gasket. Install gaskets on the
pipe ends of one of the two modules to be mated. Be sure
the gasket is completely on the pipe so damage will not
occur in the next step. One groove by groove 6” nipple per
header is required to complete the connection between
each module. 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. Make
sure that the oval neck of the bolt engages into the bolt
hole of the housing. Tighten nuts alternately and equally
until the bolt pads meet and make metal to metal contact.
Tighten nuts by another 1/4 to 1/2 turn to make sure the nuts
and bolts are snug and secure; the use of a torque wrench
is usually not required. Be aware that uneven tightening
of bolts may cause the gasket to be pinched resulting in
immediate or delayed leaks.
Header Insulation
Chilled water piping is pre-insulated on each module at
the factory with 3/4” closed cell insulation. After bolting
all modules together and leak testing, the entire coupling
connection will need to be insulated by the installing
contractor.
