UNSCREW 4 CIRCUIT BOARD MOUNTING SCREWS AND
CAREFULLY LIFT CIRCUIT BOARD WITHOUT DAMAGING
MICROSWITCHES IN THE CENTER.
DISCONNECT RIBBON WIRE CONNECTORS FROM PLUG IN
SOCKETS OF CIRCUIT BOARD AND MARK UNUSED PIN FOR
REINSTALLATION PURPOSES.
UNSCREW MOTOR MOUNTING SCEWS (4 PER MOTOR) AND
REMOVE MOTORS.
VERIFY THAT SMALL GEAR ATTACHED TO MOTOR IS NOT
DAMAGED AND SPRING PIN IS NOT BROKEN.
UNSCREW 3 MOUNTING SCREWS OF LIFTING CAM CYLINDER
WITH ROLLER BEARINGS AND PULL IT OFF THE ASSEMBLY.
VERIFY THAT ALL 3 ROLLER BEARINGS ARE FASTENED SECURELY
AND NO VISUAL DAMAGES ARE SHOWN ON THE MOULDED LIFTING

MOULDED ARROWS IN BLACK VALVE HOUSING AND IVORY
MAIN GEAR HAVE TO LINE UP (TIIMING) WHEN ACTUATOR IS
POSITIONED IN FILTER POSITION.
CAREFULLY TAKE MAIN GEAR OFF ACTUATOR BOTTOM
(PREFERABLY IN VIRTICAL POSITION) – VERIFY THAT STEEL
BEARINGS DID NOT LEAVE SIGNIFICANT ROLLER MARKS IN PLASTIC
GEAR AND THAT NO GEARS ARE BROKEN OFF.
CHECK ACTUATOR SHAFT COUPLER – BRASS INSERTS MUST BE IN
PLACE. CHECK PUMP LIMIT SWITCH FOR PROPER FUNCTIONING
(NORMALLY CLOSED WITH GEAR REMOVED OR IN POSITION)

CHECK FOR DEBRIS IN LIFTING CAM POSITIONING SLOTS.
ONE SHOULD BE ABLE TO ROTATE THE MAIN GEAR (MOTORS
REMOVED AND NO PRESSURE IN VAVLE) CLOCKWISE WITH
MODERATE FORCE AND THE VAVLE ROTOR SHOULD BE LIFTING UP
AND ROTATING. ONCE THE POSITIONING RIBS ARE LINED UP WITH
THE POSITIONING SLOTS – ROTATE COUNTER CLOCKWISE AND THE
LIFTING CAM BODY SHOULD SEAT ITSELF. ONCE SEATED THE BALL
BEARINGS SHOULD BE SPINING FREELY. CAUTION: MAKE SURE TO
POSITION THE GEAR WITH THE TIMING ARROWS ALIGNED AS SHOWN
IN PREVIOUS SLIDE.
