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.
Assembly
ClimaCool recommends locking down the chiller to a
concrete base, or to three 4” base mounting rails, using the
six bolt holes provided in each base pan. Confi rm that bolts
have been properly tightened during installation.
Electrical
It is imperative to turn off 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 confi rmed to be off :
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 as required all electrical terminal
connections on each module. 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 Master Control Panel. Field
connections are simplifi ed requiring only a two
conductor shielded cable daisy chain from the Master
Controller 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 fi eld wiring must be identifi ed
(tagged).
4. All fi eld connections should be check 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 fi eld installed
pressure diff erential fl ow switch.
7. Verify proper installation of the fi 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. Confi rm the settings on all pressure switches.
Water System
1. Confi rm that leak testing has been carried out.
2. Confi rm that the system is clean.
3. Confi rm that necessary water treatment systems are in
place with the evaporator water systems.
4. Confi rm that appropriate water analysis has been
conducted by the end-user or facility manager.
5. Confi rm that the results of this water analysis does not
confl ict with the acceptable constituent ppm levels as
indicated in Table 1, page 18.
6. Confi rm the chilled water circulating pumps are
operational and water is fl owing through the
exchanger.
7. Shut entering water valve and blow out some water
to check for particles or coloration from suspended
particles. Record the pressure diff erential across the
chiller heat exchanger, measured at the Pete’s ports at
each module.
8. Confi rm correct water fl ow rates through the
evaporator. Acquire the design parameters for the
chiller bank form the ClimaCool Selection Program data
(available from our local Representative). Compare the
measured diff erential pressures from step 7 above with
the predicted fl ow rates to ensure proper correlation to
the fl ow results.
9. Verify proper installation of the fi eld installed
temperature sensors and wells and verify calibration of
sensors read through CoolLogic Master Control Panel.
10. Confi rm installation of mandatory fi eld installed chilled
water strainer with minimum of 60 mesh screen.
