Customer wiring interface connections are shown in
the electrical schematics and connection diagrams that
are shipped with the unit. The installer must provide the
following components if not ordered with the unit:
Sound power levels
• Power supply wiring (in conduit) for all field-wired
connections
Discharge
• All control (interconnecting) wiring (in conduit) for field
supplied devices
Measurement conditions:
• Fused-disconnect switches

Heater Power Supply
The evaporator shell is insulated from ambient air and
protected from freezing for temperature down to -20°C
by two thermostatically-controlled immersion heaters
combined with evaporator pumps activation through
Tracer UC800. Whenever the ambient temperature
drops below 0°C the thermostat energizes the heaters
and the Tracer UC800 activates the pumps. If ambient
temperatures below -20°C are expected, contact your
Trane local office.
CAUTION! The control panel main processor does
not check for loss of power to the heat tape nor does
1000 2000
it verify thermostat operation. A qualified technician
37 37
must frequently verify power to the heat tape and
40 30
confirm operation of the heat tape thermostat, to avoid
42 32
42 34
catastrophic damage to the evaporator.

CAUTION! With factory-fitted disconnect switch, trace

heating is taken from the live side of the isolator so

power remains on. Supply voltage to the heating tapes

is 400V.

In case of winter water drainage for freeze protection, it
56 50
49 40
is compulsory to disconnect the evaporator heaters to
53 47
protect them from burning due to overheat.

Water Pump Power Supply
Provide power-supply wiring with fused disconnect
switch(es) for the chilled water pump(s).
Interconnecting Wiring

input through a flow proving switch (6S51) and an
62 56
auxiliary contact (6K51). Connect the proving switch and
65 59
auxiliary contact to terminal 2 connector J2 cards (1A14).

Chilled-Water Pump Control
71 64
75 69
64 56
An evaporator water-pump output relay closes when
71 65
the chiller is given a signal to go into the AUTO mode
74 69
of operation from any source. The contact is opened to
turn off the pump in the event of most machine-level
diagnostics, to prevent the buildup of pump heat.
CAUTION! The evaporator water pump output relay
must be used to control the chilled water pump and to
benefit from the water pump timer function at startup
and shutdown of the chiller. This is required when
the chiller is in operation under freezing conditions,
especially if the chilled water loop does not contain
glycol.
CAUTION! Refer to Freeze Protection section for
information about the evaporator circulating pump.
