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.

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.
