2. Observe the pressure on the pressure gauge. The normal
operating pressure is between 2.5 and 3.5 bars. Please
note the operating pressure must not exceed 3.5 bars in
order to avoid damages!
3. First check whether the connections of your drainage
system are tight and place the drain plunger on the
blocked drain.
4. Press the compressed air release button (2) on the handle to clear the
obstruction. Attention: The air inside the drain plunger is released with a loud
bang! To achieve optimum action, press with one hand against the pressure
lever and release air with the release button (2). For best results, there must
be as little air as possible between the attachment of the drain plunger and
the obstruction. If required, fill the free space between the obstruction and the
pipe end on which the drain plunger is placed, with water.
5. Flush with plenty of water. If necessary, repeat the process several times to
remove stubborn obstructions.
Safety Valve
The safety valve is factory set. If pressure becomes too high,
air is released through the safety valve.
Do not modify the safety valve in any way.
Cleaning and Storing
Clean the drain plunger ant the attachments with soapy
water. Do not immerse the drain plunger in water.
Wipe the surface with a dry or moistened cloth. Do not use abrasives or
chemicals for cleaning.
Store the drain plunger out of reach of children. Protect the drain plunger from
dust and dirt.
