Daily Unit Start-up
1. Verify the chilled water pump and condenser water
pump starter are in ON or AUTO.
2. Verify the cooling tower is in ON or AUTO.
3. Check the oil tank oil level; the level must be visible
in or above the lower sight glass. Also, check the oil
tank temperature; normal oil tank temperature
before start-up is 140°F to 145°F (60.0°C to 62.8°C).
NNootteess::
The oil heater is energized during the
compressor off cycle. During unit
operation, the oil tank heater may be de-
energized.
If the chiller is equipped with the free
cooling option, ensure that the free
cooling option is disabled in the Chiller
Settings menu.
4. Check the chilled water setpoint and readjust it, if
necessary, in the Chiller Settings menu.
5. If necessary, readjust the demand limit setpoint in
the Chiller Setpoints menu.
6. Press AUTO.
The control panel also checks compressor motor
winding temperature and a start is initiated after a
minimum restart inhibit time if the winding
temperature is less than 265°F (129.4°C). The chilled
water pump relay is energized and evaporator water
flow is proven. Next, the control panel checks the
leaving evaporator water temperature and compares it
to the chilled water setpoint. If the difference between
