Oil Level Safety
The Bitzer CSH compressor used on the HFO10 uses an optical oil-level control. This consists of a prism and an
opto-electronic unit (OLC-D1) (refer to wiring diagram). The prism, a glass cone, is mounted directly into the
compressor body and the opto-electronic unit is screwed into the prism. If the oil level drops below the optical
sensor, the red LED light comes on, indicating a low oil level. If the sensor does not detect an oil level for 5
seconds, the oil level control switch opens, and the machine shuts off. See Figure 26 and Figure 27 for location
on the machine.

Note:
If the LED blinks, there is a problem with the oil sensor (low voltage supply or sensor is installed
incorrectly).
Compressor Crankcase Heater (200 Watt)
When electrical power is supplied to terminals L1, L2, and L3 of the control panel, the crankcase heater is
energized when the machine is not operating. It is de-energized when the compressor contactor is energized.
In case of a power interruption, or crankcase heater failure, the crankcase heater should be powered on for a
minimum of 2 hours before restarting machine manually. See Figure 26 and Figure 27 for location on the
machine.
Oil Separator
To handle all oil management needs, an integrated oil separator is installed inside the Bitzer CSH compressor.
The integrated oil separator and built-in suction gas-cooled motor simplify the system integration and enable a
compact and cost-effective system design.
Control Circuit Protection
The electrical control circuit of the machine is protected by a 2-pole, 3A circuit breaker. If the breaker opens, the
machine stops immediately. Before opening the panel to reset the breaker, open the disconnect switch to the
machine and set the
Clean/Off/Ice
selector switch to the
Off
position.
When ready to restart the machine, set the
Clean/Off/Ice
selector switch to
Ice
and press
Start
. A harvest cycle
starts, and once completed, a new freeze cycle begins.
