General Start up
Start Up Preparation
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
Trane Service 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
(Refer to certied drawings).
• Check clearance around condenser (Refer to certied
drawings).
• Chilled water circuit ready to operate, lled 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.
• Open the vent on the pump body to ll the pump with
water.
• 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.
• Check that main power supply switch is sound.
• Check the unit power phasing to be sure that it has
been installed in an “ABC” sequence.
• Check Ethylene glycol or Propylene glycol % in the
chilled water circuit.
• Water ow control checking: decrease the water ow
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 (See
graphics…..).
• 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 enough demand for cooling on the
day of the start-up (around 50% of the nominal load as
minimum).
• When ball valve is present on the refrigerant suction
line, to check if the valve is open before starting the
unit.
• Check and set, as required, all Tracer™Symbio800
TD7 menu items
Water System Flow Rates
Establish a balanced chilled water ow through the
evaporator. The ow rates must fall between the
minimum and maximum values. Chilled water ow
rates below the minimum values will result in laminar
ow, which reduces heat transfer and causes either loss
of EXV control or repeated nuisance, low temperature
cutouts.
Water System Pressure Drop Measure water pressure
drop through the evaporator at the eld-installed
pressure taps on the system water piping. Use the same
gauge for each measurement. Measure ow at the eld-
installed supply and return. This will include valves,
strainers, and ttings in the pressure drop readings.
Pressure drop readings should be approximately those
shown in the Pressure Drop Charts in the Installation-
Mechanical section.
WARNING Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
Time before working on the electrical panel of the unit
with Low Ambient option
Once the unit is off (confirmed by the extinction of the
display), it is mandatory to wait five minutes before
working on the electrical panel. Refer unit manual
(Addendum_PROD-SVX01) for electrical components
safety instructions.
WARNING Live Electrical Components!
During installation, testing, servicing and
troubleshooting of this product, it may be necessary to
work with live electrical components. Have a qualied
licensed electrician or other individual who has been
properly trained in handling live electrical components
perform these tasks. Failure to follow all electrical safety
precautions when exposed to live electrical components
could result in death or serious injury
CAUTION! When using freeze inhibitor, never ll the
system with pure glycol. Always ll the system with
diluted solution. Maximum concentration of Glycol is
40%. Higher glycol concentration will damage pump
seal.
CAUTION! The pump must not run dry. Dry-running will
damage the mechanical seal.
CAUTION! Proper Water Treatment! The use of
untreated or improperly treated water in the chiller may
result in scaling, erosion, corrosion, algae or slime. It
is recommended that the services of a qualied water
treatment specialist be engaged to determine what
water treatment, if any, is required. Trane assumes no
responsibility for equipment failures which result from
untreated or improperly treated water, or saline or
brackish water.
CAUTION! Strainer should be cleaned after water ow
has been established for the rst time, as it is likely that
it collects all the particles left after eld installation.
