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 #22 AWG minimum up to 50 feet, rated 

at 60°C minimum.  See ARC156 Wiring Specifications on 

page 17. All field wiring must be identified (tagged). Refer 

to Power Distribution Drawing on page 29 .

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

 

CAUTION/ATTENTION

Use only copper conductors for field 

installed wiring. Unit terminals are 

not designed to accept other types of 

conductors.

Utilisez uniquement des conducteurs en 

cuivre pour le câblage. Bornes de l’unité 

ne sont pas conçus pour accepter 

d’autres types de conducteurs.

 

WARNING/ADVERTISSEMENT

Disconnect power supply(ies) 

before servicing. Refer servicing 

to qualified service personnel. 

Electric shock hazard. May 

result in injury or death!

Debrancher avant d’entreprendre 

le dépannage de l’appareil. 

Consulter un réparateur qualifie 

pour le dépannage. Risque de 

choc électrique. Résiltat de mai 

dans dommages ou la mort!

 

CAUTION/ATTENTION

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.

Conifer la maintenance à un 

technicien qualifie. Le systéme

Décomprimer avant d’exposer 

à la flamme. Récuperer le 

frigorigene et le stocker ou le 

détrulre correctement.
