Installation

Preparation for start-up

Carry out all operations on check list
so that the unit is correctly installed
and ready to operate. The installer
must check all the following points
before calling in the Trane Servicing
Department to put the equipment into
service:
• Check position of the unit
• Check unit is level
• Check type and position of the
rubber pads
• Check clearance required for
maintenance (Refer to certified
drawings)
• Check clearance around condenser
access if split installation (CCUN
+ remote condenser - Refer to
certified drawings)
• Chilled water circuit ready to
operate, filled with water, pressure
test carried out and air purged
CAUTION! It is prohibited to start
the water pumps when the water
loop is not filled with water. Doing
this can severely damage the
mechanical seal of the pump.
• Chilled water circuit must be
rinsed
• Check the presence of water
strainer ahead of evaporator
• The strainers must be cleaned
after 2 hours of pumps operation
• Check the thermometers and
manometers position
• Check chilled water pumps
interconnection to control panel
• Ensure that the isolation resistance
of all power supply terminals to
ground complies with standards
and regulations in force
• Check that unit voltage and
frequency supplied match rated
input voltage and frequency
• Check that all electrical
connections are clean and sound
• Check that main power supply
switch is sound
• Check Ethylene glycol or
Propylene glycol concentration in
the chilled water circuit
• Water flow control checking:
decrease the water flow and
check the electrical contact in the
control panel
• Check chilled water pressure drop
through evaporator (unit without
hydraulic module) or unit available
pressure (unit with hydraulic
module) are in accordance with
the Trane order write-up.
• On start-up of each motor in the
system, check the direction of
rotation and operation of all the
components they drive
• Check that there is sufficient
demand for cooling on the day of
start-up (around 50% of nominal
load)
