Preparing for Installation.
Prepare the modules for installation by carefully removing 
the module's packaging, unbolt the module from the skid, and 
lift the module with a crane or hoist into its final position.
Hardware kits are shipped in separate packaging along with 
the modules. Make sure the hardware kits are on site when 
connecting the modules.
SITE PREPARATION
Base Requirements
The minimum base requirement for the ClimaCool chiller 
is a level surface which has been checked to ensure that it 
is capable of bearing the combined operating weight of the 
modules (see page 4).
Anti-Vibration Mountings
Although the compressors are installed on anti-vibration 
mountings, further isolation of the chiller from the structure 
can be achieved by installing vibration-eliminating springs or 
pads under the base rails on which the chiller will rest. (see 
page 7 - Vibration Isolation).
Service Access
The minimum space required for electrical panel service is 
36" in the front of each module. Allow 24" service clearance 
in the back of the module for refrigeration access. Allow a 
minimum of 18” of clearance above the module for service. 
Allow 12” side clearance of any ClimaCool modular chiller 
system (see Service Clearances page 6). Local building or 
electrical codes may require additional clearance.
Draining
When performing standard maintenance procedures such 
as flushing heat exchanger, it will be necessary to close off 
a section of a module. ClimaCool modular chillers come 
equipped with isolation valves for this purpose. Access to a 
floor drain is helpful when performing standard maintenance 
procedures.
INSTALLATION
Assembling Modules
Use of (2) 4” rails (minimum size) is required for ease of 
installation. One of the end modules should be chosen as the 
reference module and carefully located. 
Site Preparation/Installation
A factory supplied fastener kit is provided for the adjoining 
of each module. Each kit contains (4) gaskets, (32) ¾” fully 
threaded studs, (64) heavy duty hex nuts, (64) lock washers, 
and (64) flat washers. 
A ¾"-10 tap should be run through each weld nut located at 
the bottom rear chiller header flange of each module. Screw 
the fully threaded studs into these four weld nut locations. 
At all other flange hole locations, insert fully threaded studs, 
attach washers, lock washers, and nuts from the fastener kit.
The gasket should be placed between the first reference 
module and the next module. Slide the next module into 
position while guiding the fully threaded studs into the flange 
holes of the next module. Finally, the washers, lock washers, 
and nuts are applied to the other end of the fully threaded 
studs to securely fasten the module flanges. 
Tighten the flange bolts in a diametrically opposite pattern, 
in such a way as to pull the modules together evenly. It will 
be necessary to use a ¾" (12 point) box-end wrench when 
tightening. As each module is added, the alignment of the 
whole package should be confirmed.
Header and Flange Insulation
Chilled water piping is pre-insulated on each module at the 
factory with ¾” closed cell foam rubber. After the bolting the 
modules together, the installer must apply insulation on site 
over the chilled water header connection flanges.
