General start-up
Preparation
Carry out all operations on check
list and 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 unit
• Check unit is level
• Check type and position of
rubber pads
• Check clearance required for
maintenance access (See
submittals)
• Chilled water circuit ready
to operate, filled with water,
pressure test carried out and air
purged.
• 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
• Insure 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 % in the
chilled water circuit if Ethylene
glycol presence is required.
• Check chilled water pressure
drop through evaporator is in
accordance with the Trane order
write-up (See Tables 14-15).
• On start-up of each motor in the
system, check the direction of
rotation and operation of all the
components they drive
• Water flow control checking:
decrease the water flow and
check the electrical contact in the
control panel.
• Check that there is sufficient
demand for cooling on the
day of start-up (around 50% of
nominal load)start-up (around
50% of nominal load)
Start-up
Follow the instructions below to
correctly start-up the unit.
Installation and chiller inspection:
• Ensure that all the operations
above (start-up preparation), are
followed.
Follow the instruction stuck inside
the electrical cabinet:
• Unscrew the screws securing the
isolators located under the rails
supporting the compressor.
• Put the plexiglass supplied by
Trane in front of the power
terminal.
• Insure all water and refrigerant
valves are in service positions,
• Insure that the unit is not
damaged,
• Insure that sensors are properly
installed in their bulb-wells and
submerged in heat conducting
product,
• Check fixing of capillary tubes
(protection from vibration and
from wear) and insure that they
are not damaged,
• Reset all manually set control
devices,
• Check refrigerating circuits
tightness
Checking and setting:
Compressors:
• Check oil level at rest. The level
should reach at least halfway up
indicator located on housing.
See fig. 6 for correct level.
