Operation
Control System
Unit operation is intergrally managed by the
microprocessor-based unit Tracer™ Symbio 800
controller.
Unit Operation
• Check that the chilled water pump(s) operates correctly
• Start up the unit following procedure described in
the unit controller user guide. The unit will operate
correctly when there is sufcient water ow. The
compressors will start up if the evaporator water
leaving temperature is above the control module
setpoint.
Weekly start up
• Check that the chilled water pump(s) operates correctly
• Start up the unit following procedure described in the
unit controller user guide
Weekend shutdown
• If the unit needs to be shut down for a short period of
time, stop the unit following procedure described in
the unit controller user guide. (See «Clock» menu)
• If the unit is shut down for a longer period, see under
«Seasonal shutdown», below
• Ensure that all safeties are taken to prevent frost
damages during negative ambient temperature
• Do not put the general disconnect switches to
off, except if the unit is drained. Trane does not
recommend draining the unit, due to the fact that it
increases corrosion
Seasonal shutdown
• Check water ows and interlocks
• Check glycol % in the chilled water circuit if glycol
presence is required
• Carry out leak test
• Carry out oil analysis
• Record operating pressures, temperatures, amperages
and voltage
• Check operation of machines/ compare conditions of
operation against original commissioning data
• Stop the unit following procedure described on the
unit controller user guide
• Ensure that all safeties are taken to prevent frost
damages during negative ambient temperature
• Fill out the visit log sheet and review with the
operator - Do not put the general disconnect switch to
off, except if the unit is drained
• Trane does not recommend draining the unit, due to
the fact that it increases corrosion
Seasonal start-up
• Check water ows and interlocks
• Check Ethylene glycol % in the chilled water circuit if
glycol presence is required
• Check operational setpoints and performance
• Calibrate controls
• Check operation of all safety devices
• Inspect contacts and tighten terminals.
• Megger the motor compressor windings
• Record operating pressures, temperatures, amperages
and voltage
• Carry out leak test
• Check conguration of unit control module
• Change the oil as required based upon results of the
oil analysis made during seasonal shutdown Get the
8 condition measurements at the same time, on each
circuit
• H P
• L P
• Suction temperature
• Discharge temperature
• Liquid temperature
• Water entering temperature
• Water leaving temperature
• Outdoor ambient temperature Then calculate the sub-
cooling and superheat. No diagnosis can be accurate
with one of these recordsmissing
• Check operation of machines/compare conditions of
operation against original commissioning data
• Fill out the visit log sheet and review with the operator
