General Start-up
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
• Put the plexiglass supplied by
Trane in front of the power
terminal
• Ensure all water and refrigerant
valves are in service positions
• Ensure that the unit is not
damaged
• Ensure 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 ensure 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 the
minimum oil level on the indicator
located on oil equalization line
(see Compressor oil level at oil
equalization line figures at the
end of “General startup” chapter)
when the compressors have been
OFF for 3 minutes for a packaged
unit (CGWN) and after 10 minutes
OFF time for a split unit (CCUN
with remote condenser). See
the “Compressor oil level at oil
equalization line for correct level.
• Check fixing of capillary tubes
(protection from vibration and
from wear) and ensure that they
are not damaged
• Reset all manually set control
devices
• Check refrigerating circuits
tightness
• Check electrical terminals
tightening of the motors and in
the control panel
• Check the isolation of the motors,
using a 500V DC megohmeter
which meets manufacturer’s
specifications (minimum value 2
megohms)
• Check the direction of the rotation
using phasemeter
CAUTION! Improper power phasing
may result in equipment damage due
to reverse rotation.
