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
halfway up indicator located on housing. See Figure 16
for correct level.
Figure 13 - Compressor oil level
1 = Max. oil level
2 = Min. oil level
• 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
Electrical power wiring
• Check all the electrical terminals tightening
• Set-up compressors overload relays
• Set-up fan-motors overload relays
Electrical control wiring
• Check all the electrical terminals tightening
• Check all the pressostats
• Check and set-up the chiller unit control module
• Test and start-up without the electrical power
Condenser
• Check direction of the rotation of fans
• Check the isolation of the motors using a 500V
DC megohmeter which meets manufacturer’s
specifications (minimum value 500 megohms)
Operating parameters statement
• Switch on main power supply switch
• Start the water pump(s) and check there is no
cavitation
• Start-up the unit following procedure described in the
CH535 controller user guide. The unit and the chilled
water pumps contactor must be connected together
• After unit start up, leave in operation for at least
15 minutes, to ensure pressures are stabilized
Then check:
• voltage
• compressors and fan-motors currents
• leaving and return chilled water temperature
• suction temperature and pressure
• ambient air temperature
• blowing air temperature
• discharge pressure and temperature
• liquid refrigerant temperature and pressure
• operating parameters
• chilled water pressure drop through
evaporator (if no hydraulic module is installed)
or unit available pressure. It must be in
accordance with Trane order write-up
• superheat: difference between suction
temperature and dew point temperature.
Normal superheat should be within 5 and 7 °C
with R410A in cooling mode
• sub-cooling: difference between liquid
temperature and bubble point temperature.
Normal sub-cooling should be within 2 and
15°C with R410A in cooling mode
• difference between dew point temperature
in high pressure and condenser air inlet
temperature. Normal value on standard unit
with R410A should be 15 to 23°C
• difference between outlet water temperature
and dew point temperature in low pressure.
Normal value on standard unit, without
Ethylene glycol in chilled water, should be
about 3.5°C
