Ratings in accordance with AHRI Standard 550/590.
The minimum/maximum flow rates are based on an approximate temperature differential of 5°F to 20°F through the evaporator and 5°F to 30°F
through the condenser. Flow rates vary based on application; verify with selection software.
Notes:

Required to provide stable operation. Storage/buffer tanks may be utilized in return piping to meet the minimum volume requirements.
Main header water/fluid connections are 6" grooved coupling for the 30, 50 and 70 ton modules. The 85 ton module uses 8" grooved couplings.
85 ton module cannot be directly coupled with 30, 50 or 70 ton modules due to a difference in header and frame size.
Module operational weight includes water, compressor oil, and refrigerant charge. Multiply times the number of modules for a total system
operational weight.
Tonnage ratings conditions: 44°F leaving chilled water temperature, 85°F entering condenser water temperature, flow rates are 3 gpm per ton
through the condenser with a fouling factor of .00025 hr-ft2-°F/Btu and 2.4 gpm per ton through the evaporator with a .0001 hr-ft2-°F/Btu fouling

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 7). One
(1) module should be chosen as the reference module and
carefully located.

Grooved Couplings Installation
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. Grooved couplings are used to adjoin a bank
of modules. This requires the temporary removal of all
top, back and side sheet metal panels to obtain additional

couplings can be installed using the following recommended
instructions:
• Review Figure 6, SHC Heat Recovery and Figure 7, SHC
Heat Pump below.
• Headers are numbered indicating the easiest order of
coupling installation.
• SHC Heat Recovery chillers should have couplings
installed on headers 1, 2 and 6 from the top and 3, 4 and
5 from the back of the unit.
• SHC Heat Pump chillers should have couplings installed
from the top.

• Remove the rubber gasket from the coupling.
• Apply a thin layer of silicone or other non-petroleum
lubricant to both the inner and outer surface of the
gasket to reduce friction.
• Slide the gaskets on the headers as shown in Figure 8.
• Be sure the gasket is completely on the pipe to
eliminate any damage to the gasket.
• With gasket in place on each header of the positioned
unit (see Figures 9 and 10), move the second module
into position and line up the piping. Ensure alignment is
maintained for any additional modules to be added.
• Open the coupling by completely removing one bolt
and nut (see Figure 11).

ing the coupling intact.
• Install with the nuts facing up for fastening.
• When the pipes 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 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 previously removed bolt from the bottom to
re-attach the two sides of the coupling (see Figure 12).
• Tighten nuts alternately and equally until the bolt pads

Electrical Phase Sequencing
Proper clockwise rotation for scroll compressor motors
is important to prevent damage to the compressors.
ClimaCool recommends the use of a phase sequence

If the discharge pressure does not increase, proper

by opening the main electrical disconnect and switching
any two of the main power supply leads feeding that
compressor’s contactor.
Proper Voltage Balance
Occasionally, in three phase circuits, a voltage imbalance
occurs between phases. It is not recommended to operate
equipment when an imbalance greater that 2% occurs. This

their longevity. The following example describes how to
calculate the average voltage of the three phases to see if
the imbalance is greater than 2%.
Example: Line 1 = 226v Line 2 = 230v Line 3 = 228v
The average is: (226+230+228) / 3 = 228v
Next, [100(228-226)] / 228 = 0.9%
The voltage imbalance of the three phase circuit is 0.9%.
This is well under the 2% range.

Examples of an acceptable load side system bypass are:
• Utilize a quantity of 3-way control valves on the largest
loads farthest from the chiller/heater system.
• Field piping with a control valve to provide a bypass
across the larger system loads when their 2-way valves
go closed.
Please refer to Figure 15 for a typical load bypass
valve arrangement. The load side system bypass should
be sized for an absolute minimum of one module’s worth
