Injection Pump Vacuum Switch
To replace the vacuum switch (P/N 063-0171-035):
1. Disable and shutdown any automatic product control features of the Sidekick Pro injection system and turn
off the vehicle when replacing the vacuum switch assembly.
2. Disconnect the vacuum switch connector from the motor control cabling. Be careful to keep dust, debris, or
liquid chemicals which may seep from the injection pump head from contaminating the cable connections.
3. Loosen the vacuum switch while securing the connected fitting to prevent damage to the pump head.
4. Apply RectorSeal
®
or equivalent thread sealant to the new vacuum switch and thread into the pump head.
5. If necessary, slide the protective covering on the vacuum switch back slightly to expose the hex surface for
tightening the vacuum switch body.
6. Tighten the vacuum switch body two or three quarter turns to secure the vacuum switch.
Note: Do not over tighten the pressure transducer. Overtightening the pressure transducer may
damage the pump head.
7. Be sure to replace the protective cover over the flow switch before operating the pump.
WARNING
Always use caution when performing
maintenance or servicing an injection pump or
system which has been previously pressurized.
Wear appropriate protective equipment to
prevent contact with hazardous chemicals and
rinse the chemical system as instructed by the
chemical manufacturer prior to performing
maintenance.
WARNING
Hazardous chemicals may be under pressure
even if the pump has not been in service
recently. Before replacing any components on
the injection pump, thoroughly rinse the
injection pump with clean water to remove
excess chemical residue.
