General Start up
Final check
When the unit is operating correctly:
• Check that the unit is clean and clear of any debris,
tools, etc…
• All valves are in operating position
• Close control and starter panel doors and check panels
fixation
CAUTION!
• For the warranty to apply, any start-up carried out
directly by the customer must be recorded in a detailed
report, which must be sent as soon as possible to the
nearest Trane office.
• Do not start-up a motor whose insulation resistance is
less than 2 meghoms
• Phase imbalance should not be greater than 2%
• The voltage supplied to motors should be within 5% of
the rated voltage on the compressor nameplate.
• Excessive emulsion of the oil in the compressor shows
that refrigerant is present in the oil and the result will
be that compressor is not lubricated enough.. Shut
down compressor and wait for 60 minutes for the
sump heaters to heat oil and start again. Should this
not work, consult Trane technician.
• Excess oil in compressor can damage the compressor.
Before adding oil, consult Trane technician. Use only
Trane products recommended.
• The compressors must operate in a single direction of
rotation. If refrigerant high pressure remains stable in
the 30 seconds after compressor start-up, immediately
shut down unit and check the direction of rotation
using phasemeter.
WARNING!
• The chilled water circuit may be under pressure. Bring
down this pressure before opening up the system to
rise out or fill up the water circuit. Failure to comply
with this instruction may cause accidental injury to
maintenance personnel.
• If a cleaning solution is used in the chilled water circuit,
the chiller must be isolated from the water circuit to
avoid all the damage risks of the chiller and evaporator
water pipes.
