Unit Operation - Temp-Cool TC-18B Owner's Manual

TC-60B3 and B4 – 3 Phase Wiring Instructions:
Only qualified personnel should install TC-60B units.
Extra care is required on the three phase units, the TC-
60B3 and TC-60B4, to insure they are connected in phase
with the incoming power. If the unit is not in phase the
condenser fan and compressor operate in reverse and
damage the compressor. If the unit is not in phase with
the power supply, the compressor will make more noise
than normal and the condenser fan will deliver very
little air. The evaporator fan can not be used to check the
phase. It has a single phase motor that operates in the cor-
rect direction regardless of the phase sequence.
If the wiring phase sequence is incorrect, reversing any
two of the three incoming power leads will solve the
problem.

UNIT OPERATION:

Placing the Unit:
1. Locate the unit on a flat, level service.
2. Keep entering and leaving air openings free of
obstructions. Maintain at least 18" of clearance
between air inlet or outlet and any wall or other
obstruction.
3. For a unit with a condensate tank, check the tank
to make sure it is in place and empty.
4. For a unit with condensate pump, make sure the
condensate discharge tubing is connected to the outlet
connection of the unit and runs to a suitable drain

or outside location. Do not crimp or bend the tubing,
or place it where something might be set on the
tubing restricting its flow. No portion of the
discharge tube should be more than 10 feet above the
level of the pump.
5. Attach any required accessories and ductwork.
6. Plug in or wire the unit to an acceptable power source.
7. When power is applied 06 should appear briefly on
the control display and disappear. The unit is now
ready for use.
Cooling Operation:
1. Press the POWER BUTTON to start the unit. The
evaporator (cooling) fan will start and the current
space temperature will be shown on the digital
display. The unit will start in the last mode used.
2. Select the Cooling mode by using the MODE button
to step through the three available modes (Cool, Heat
and Fan) until the cooling mode indicator light comes
on. The unit is now in the cooling mode.
3. Press the Up or Down temperature button to see the
current cooling setpoint temperature. Adjust the
setpoint temperature to the desired value by pressing
the Up or Down temperature button repeatedly, until
the desired temperature is reached. The display will
flash six times at the new setpoint then the actual
room temperature will be displayed. In the cooling
mode up to five minutes may lapse between turning
the unit on or resetting the temperature and the
compressor starting. This delay is a result of the anti
short cycling program in the thermostat. A green dot
will appear in the lower right hand corner of the
temperature display when the compressor is being
energized.
4. The compressor and condenser fan will continue
to operate until the space temperature drops to the
setpoint temperature. At that point the compressor
and condenser fan will shut off, but the evaporator
fan will continue to run until the unit is turned off.
Fan Operation:
1. Press the POWER BUTTON to start the unit. The
evaporator (cooling) fan will start and the current
space temperature will be shown on the digital
display. The unit will start in last mode used.
2. Select the Fan mode using the MODE button to step
