Dosing Pump Hoses
The hoses of the dosing pumps must be replaced annually or earlier if worn. Use original replacement hoses only. They can be
obtained from your swimming pool dealer.
Hose change
The dosing pump's hose is replaced without removing the rotor.
Remove the empty suction and pressure hoses from the hose fastener. To do so, loosen the blue clamp screws.
Remove transparent cover 1 from the pump.
Remove transparent cover 2 from the rotor.
Turn rotor 3 such that the flat side faces left and is vertical.
Pull hose fastener 4 from its bracket and lift on the left side.
Turn rotor 3 clockwise and remove the cable while lifting on it until it is completely free.
To install, perform in the opposite order.
Either the hose can be replaced alone, or the hose and hose fastener can be replaced jointly. It is recommended to replace hose and
hose fastener jointly.
