Installing the hose
Do not allow unauthorised persons near the pump during
maintenance work.
Preparations
It is important to ensure that following parts are thoroughly
cleaned prior to installation:
• Pump housing
• Hose leak detector
• Components such as bolts and flanges
Trim away any rubber flashings immediately behind the
collar ends of the hose. This is necessary to ensure proper
seating of the “O” ring.
Lubricate the hose thoroughly with glycerine before
installing.
Be sure that the maintenance switch is in off position. The
rotating of the rotor is meant to be done without electricity
and with the crank cam.
1. Turn the rotor to its topmost position using the crank
cam.
2. Ensure the hose compression adjustment is in the 0%
position.
