Release of the reflux protection device:
In case the hose burst protection device interrupts the water supply, first find the reason and remove it as
necessary. Close the water tap. Release the valve by a half left-turn of the upper knurled part. You can
hear the release of the valve as a clicking noise. Tighten the burst protection device against the water tap
by a right turn. Open the water tap slowly afterwards.
Maintenance of the assembly of hose burst protection and reflux protection devices:
Calcification can impair the function of both valves. We recommend an annual inspection by a skilled
plumber. The plumber should remove the safety kit with the reflux protection device to check both valves
by hand for proper function, calcification or blockage.
CAUTION
Danger of calcification.
Impairment of valve function.
Have a plumber inspect the two valves annually.
Remove calcifications by citric acid or acetic acid solutions.
Continue by testing the function and tightness of the mounted unit.
Check: Quickly open the water tap while there is no chamber connected – the valve should cut off the
water flux without any delay.
