Removal and Maintenance of Cartridge

This thermostatic cartridge has screens to prevent dirt and unwanted particles from damaging the valve.

2.
Shut off the water inlets by tightening the two screws at the two check stop valves.

Clean the screens and rinse with water. If necessary, soak in a 50/50 mix of white vinegar/ water or
a de-scaling agent until all dirt is dissolved. Grease the o-rings with a silicone based grease and wipe
the housing with a wet cloth before reassembling.
6.
Reassemble the valve by reversing these instructions. Make sure the red dot on the temperature
limit stop ring and push button on the handle are both
aligned in the 12 o’clock position.

the handle must be turned on an occasional basis.
