B. REPLACEMENT OF EVAPORATOR
TEMPERATURE SENSOR
1. Remove front rear and top panels on models
ACM 85 and AC125-175 and top and left side
panel on model AC 225.
2. Remove the evaporator cover and snap off
the metal clip securing the sensor probe to the
serpentine.
3. Trace the evaporator sensor terminal plug
on the rear side of the control box (blue color)
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 front panel and on AC 225, the left
side panel while on water cooled version of
ACM 85 and AC 125-175 it is required to remove
even the rear 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 securing the probe to the
refrigerant liquid line.
3. Trace the condenser sensor terminal plug
on the rear side of the control box (black color)
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 AMBIENT
TEMPERATURE SENSOR
1. Remove front panel and on AC 225, the left
side panel while on water cooled version of
ACM 85 and AC 125-175 it is required to remove
even the rear panel.
2. Trace the ambient sensor probe holded on
its metal bracket in front of the condenser fins-on
air cooled version-and remove it by unloosing its
securing plastic clamp.
On water cooled version, remove it by opening
the plastic strap securing the probe on the water
supply line to the condenser.
3. Trace the ambient sensor terminal plug on
the rear side of the control box (red color) and
remove it from its socket by carefully pulling out
the terminal plug securing clip.
4. To install the replacement ambient sensor
follow the above steps in reverse.
E. REPLACEMENT OF OPTICAL ICE LEVEL
CONTROL
1. Remove the front panel and on AC 225, the
left side panel while on water cooled version of
ACM 85 and AC 125-175 it is required to remove
even the rear panel.
2. Trace the optical ice level control terminal
plug (the only one with four terminal pins) on the
rear side of the control box and remove it from its
socket by carefully pulling out the terminal plug
securing clip.
3. Remove the optical ice level control assy
from the interior of the storage bin by unloosing
its two securing screws.
4. Withtraw the entire optical ice level control
wire and terminal plug through the hole located in
the storage bin.
5. To install the replacement optical ice level
control follow the above steps in reverse.
F.

REPLACEMENT OF P.C. BOARD

1. Remove front panel.
2. Remove all sensor terminal plugs, located
on the rear side of P.C. Board, by carefully
releasing them out from their sockets clips.
3. Disconnect the terminal board connection
plug from the rear side of P.C. BOARD then
unloose the four screws holding the same to the
plastic control box and remove it.
4. To install the replacement P.C. BOARD
follow the above steps on reverse.
G. REPLACEMENT OF THE WATER PUMP
(ACM 85)
1. Remove top panel and evaporator cover.
2. Disconnect the wires from the water pump
motor.
3. Unloose the screws holding the metal
bracket of the water pump to the sump.
4. Through the curtined opening reach the
discharge port of the water pump and disconnect
the plastic hose.
5. Unloose screw, washer and lockwasher
and take the water pump off the bracket.
6. To install the replacement pump follow the
