PRIMING THE PUMP
1. It is essential to prime the pump on initial start-up and each time
the water supply is disconnected from the unit after initial use.
2. Lay the high pressure hose out to remove any loops. Water flow will
constrict the hose, creating tight loops if the hose is not straight.
3. Securely connect the gun assembly to the high pressure hose.
NOTE: The nozzle assembly should NOT be connected to the gun
assembly at this time. See "Nozzle Connection" .
4. With the trigger gun locked in the "OFF" position, turn the water
supply completely on. Pointing the gun in a safe direction, unlock
the trigger gun and squeeze the trigger.
5. Low pressure water will begin flowing from the hose/gun assembly.
This allows the unit to prime and purge any air from the system.
The unit is primed when water flow is uninterrupted by air.
6. Once the unit is primed, release the trigger and lock the gun in the
"OFF" position. Securely connect the nozzle assy. (See "Nozzle
Connection")
