Release of the reflux protection device:
In case the burst protection device interrupted the water supply, find first the reason and remove it as far
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 device with reflux protection device:
Calcification can impair the function of both valves. We recommend an annual inspection by a skilled
plumper. The plumper should demount the safety kit with reflux protection device to check both valves by
hand for function and 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.
 Afterwards test the function and the tightness of the mounted unit.
Check: Quickly open the water tap while there is no chamber connected – the valve has to cut off the
water flux without any delay.
4.4 Electrical connection
The constant climate chamber comes with a fixed power connection cable that has a length of 1800 mm /
5.9 ft. The socket must also provide a protective conductor.

Prior to connection and start-up, check the power supply voltage. Compare the values to the specified
data located on the unit’s type plate (left unit side, bottom right-hand, see chap. 1.4).
When connecting, please observe the regulations specified by the local electricity supply company and
as well the VDE directives (for Germany). We recommend the use of a residual current circuit breaker.
