Pre-Startup
All startups must be performed by ClimaCool factory
trained personnel. Prior to chiller startup, there are certain
essential checks which must be completed. Failure to carry
out these checks could result in damage to the chiller
voiding the modules warranty.
Electrical
It is imperative to turn o the main electrical power supply
and follow proper lock-out/tag-out procedures prior to
servicing any of the chiller’s electrical components. The
following procedures can be performed only after the
electrical power is conrmed to be o:
1. The installation must be inspected and approved by the
respective agent and be in compliance with all local and
national electrical codes.
2. Check and tighten all electrical terminal connections on
each module as required. Utilize any lock-out/tag-out
procedures required for your project location when
performing this operation. If no procedure exists, take
all precautions necessary to prevent the power from
being turned on. A systematic tightening of all terminals
inside the electrical control panel on each module
should be carried out. This will include the compressor
motor terminals, which would require removal of the
compressor terminal cover. Check connections at each
safety and every termination in the panel.
3. Verify that a separate 115 volt power supply is used to
power the CoolLogic Control System. Field connections
are simplied requiring only a two conductor shielded
cable daisy chain from the Master Control Panel to the
modules. These control wires should be two-conductor
shielded having #18 AWG minimum up to 50 feet, #16
AWG minimum up to 100 feet, rated at 60°C minimum.
All eld wiring must be identied (tagged). Refer to
Power Distribution Drawing on page 45.
4. All eld connections should be checked for tightness.
5. Check all fuses for proper sizing as indicated on the
chiller data plate and/or the electrical diagram on the
inside door of the electrical panel.
6. Verify proper operation of the mandatory eld installed
pressure dierential ow sensor or switch.
7. On 208/230v units, conrm tranformers are properly
tapped for the measured incoming power supply.
8. Verify proper installation of the mandatory factory
provided, eld installed voltage/phase monitor.
Refrigeration
1. Refrigerant piping and components should be inspected
for damage.
2. Place refrigerant gauges on the discharge and suction
access ports of each refrigerant circuit to ensure a
refrigerant charge is present. Leave the gauges on for
compressor rotation check.
3. Conrm the settings on all pressure sensors.
Water System
1. Conrm that leak testing has been carried out.
2. Conrm that the system is clean.
3. Conrm that necessary water treatment systems are
in place with both the evaporator and condenser
water systems.
4. Conrm that both the chilled water and condenser
water circulating pumps are operational and water is
owing through both exchangers.
5. Shut the entering water valve and blow out some
water to check for particles or coloration from
suspended particles. Record the pressure dierential
across the chiller and condenser heat exchangers,
measured at the pete’s ports at each module.
6. Conrm correct water ow rates through the
condenser and evaporator. Acquire the design
parameters for the chiller bank from the ClimaCool
Selection Program data (available from the local
representative). Compare the measured dierential
pressures from step 5 above with the predicted ow
rates to ensure proper correlation to the ow results.
7. Verify proper installation of the mandatory factory
provided, eld installed temperature sensors and
wells (sensor should be fully inserted in the well) and
verify calibration of sensors read through the CoolLogic
Control System.
8. Conrm installation of mandatory eld installed
condenser and chilled water strainers with a
minimum of 60 mesh screens.

WARNING
This unit contains HFC-(R410A), an azeotropic mixture of R-32 (Difluoromethane) and R-125 (Pentafluoroethane).
DO NOT VENT HFC-(R410A) to the atmosphere. The U.S. Clean Air Act requires the recovery of any residual
refrigerant. Do not use R-22 service equipment or components on R410A systems.
WARNING!
WARNING! To avoid possible injury or death due to electrical
shock, open the power supply disconnect switch and secure it
in an open position during installation.
CAUTION!
CAUTION! Use only copper conductors for field installed
electrical wiring. Unit terminals are not designed to accept
other types of conductors.
