ADJUSTMENT, REMOVAL AND REPLACEMENT PROCEDURES

NOTE. Read the instructions thoroughly
before performing any of the following
adjustment or removal and replacement pro-
cedure.
A. ADJUSTEMENT OF THE EVAPORATOR
WATER LEVEL
The correct water level in the freezing cylinder is
about 25 mm. (1") below the ice discharge
opening. Low water level causes excessive strain
inside the freezer assembly due to a faster freezing
rate.
When the water level is above or below the
correct one, adjustment can be performed to
Raise or Lower the water level by raising or
lowering at the measure required, the water
reservoir and its mounting bracket.
1. To Raise the water level:
a. Loosen and remove the screw securing the
mounting bracket of the water reservoir to the
unit cabinet and raise the water reservoir to the
correct level.
b. Thread the mounting screw in the
corresponding hole and tighten it.
2. To Lower the water level follow the above
indications to lower to the correct level the water
reservoir assembly.
WARNING. Be sure the electrical power
supply circuit breaker and the inlet water
supply are OFF, before starting any of the
following Removal and Replacement
procedures as a precaution to prevent
possible personal injury or damage to the
equipments.
B. REPLACEMENT OF EVAPORATOR
TEMPERATURE SENSOR
1. Remove the front, rear and top panels.
2. Remove the insulation from the refrigerant
tubing, connecting the freezer to the accumulator,
to gain access to the sensor probe well and be
able to pull out from this well the sensor probe.
3. Trace the condenser sensor terminal plug
(blue) on the left side of the control box and
remove it from its socket by carefully pulling out
the terminal plug securing clip.
4. To install the replacement evaporator sensor
follow the above steps in reverse.
C. REPLACEMENT OF CONDENSER
TEMPERATURE SENSOR
1. Remove the front panel.
2. Trace the condenser sensor probe located
within the condenser fins on air cooled version
and withtrow it.
On water cooled version remove it by opening
the plastic strap (reusable) securing the probe to
the refrigerant liquid line.
3. Trace the condenser sensor terminal plug
(black) on the left side of the control box and
remove it from its socket by carefully pulling out
the terminal plug securing clip.
4. To install the replacement condenser sensor
follow the above steps in reverse.
D. REPLACEMENT OF THE ICE LEVEL
LIGHT CONTROL
1. Remove the front , rear and top panels.
2. Trace the ice level light control terminal plug
(black and with four terminal pins) on the left side
of the control box and draw it out from its socket
by carefully slackening the fastening tie.
3. Unloose the two screws holding the optical
ice level control to the upper side of the spout and
remove it.
4. To install the replacement ice level light
control follow the above steps in reverse.
E. REPLACEMENT OF THE GEAR MOTOR
ROTATION AND SPEED SENSOR
1. Remove the front, rear and top panels.
