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 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 confirmed 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 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 simplified 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 field wiring must be identified (tagged). Refer to
Power Distribution Drawing on page 53 .
4. All field 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 field installed
pressure differential flow sensor or switch.
7. On 208/230v units, confirm tranformers are properly
tapped for the measured incoming power supply .
8. Verify proper installation of the mandatory factory
provided, field 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. Confirm the settings on all pressure sensors.
Water System
1. Confirm that leak testing has been carried out.
2. Confirm that the system is clean.
3. Confirm that necessary water treatment systems
are in place with both the evaporator and condenser
water systems .
4. Confirm that both the chilled water and condenser
water circulating pumps are operational and water is
flowing 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 differential across the
chiller and condenser heat exchangers, measured at the
pete’s ports at each module .
6. Confirm correct water flow 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 differential pressures from step 5 above with
the predicted flow rates to ensure proper correlation to
the flow results.
7. Verify proper installation of the mandatory factory
provided, field 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. Confirm installation of mandatory field installed
condenser and chilled water strainers with a minimum
of 60 mesh screens.
Pre-Startup
Disconnect power supply
(ies) before servicing. Refer
servicing to qualified service
personnel. Electric shock
hazard. May result in injury
or death!
Unit to be serviced by
qualified personnel only.
Refrigerant system under
pressure. Relieve pressure
before using torch. Recover
refrigerant and store or
dispose of properly.
