Unit Start-Up Procedures

Prior to calling for start-up services or commissioning,
CICD Compact Chiller Installation Completion Check List
and Request for Trane Service, CG-ADF003*-EN, must be
completed and submitted. Once that has been completed
and submitted, CICD Compact Chiller Start-up Check List,
CG-ADF004*-EN, must be followed and submitted. A hard
copy of each document is sent with the chiller in the IOM
notebook.
Start-up and commissioning must be performed by a
factory authorized Trane service technician.

Pre-Start

Complete each step in the "Pre-Start Up Procedures"
included in the CICD Individual Chiller Start-up Check List
and check off each step as completed.

result in death or serious injury. Disconnect all electric
power, including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure the
power can not be inadvertently energized.

NOTICE
Equipment Damage!
• To prevent overheating at connections and under-
voltage conditions at the compressor motor, check
tightness of all connections in the compressor power
circuit.
• To prevent compressor damage, do not operate the
unit with discharge or liquid line service valves
closed.
• The use of untreated or improperly treated water in a
Chiller may result in scaling, erosion, corrosion, algae
or slime. It is recommended that the services of a
qualified water treatment specialist be engaged to
determine what water treatment, if any, is required.
Trane assumes no responsibility for equipment
failures which result from untreated or improperly
treated water, or saline or brackish water.
• To prevent evaporator or condenser damage, pipe
strainers must be installed in the water supplies to
protect components from water born debris. Trane is
not responsible for equipment damage caused by
water born debris.
