1. Remove the screws and then remove the
complete switch including diaphragm.
2. Remove the cables from the motor cable
and power source.
3. Take the new switch and attach the cables
24 V
to motor and power source.
4. Locate the new diaphragm and then the
new complete switch.
Change of Diaphragm kit
1. Remove the screws with a Torx #20 tool
(a standard Phillips driver type screw
#20 tool). (Screws should be fitted to the
through holes which can be seen on the
8 A
backside of the motor end bell).
2. Separate the pump assembly from motor.

tool).
4. Hold the black pumpbody towards the
ground. Carefully remove the diaphragm
kit from pump body. Ensuring that posi-
tions still remains together with pump
body.
5. Locate the diaphragm kit into pump body
and mount the five short screws into the
threaded holes in the motor flange.
6. Mount the complete pumphead kit onto
the motor coupling flange taking notice to
fit the slot in cam in right position against
motor shaft and the three slots on motor
end bell.
7. Assemble the remaining long screws
which will hold the motor/pump unit to-
gether. Screws should be fitted to the
through holes that can be seen on the
backside of the motor end bell).
Change of complete Pump kit
24V 1. Remove the screws and then remove
23 complete switch including diaphragm.
