3.2.6 Adjusting Wap automatic calcification alarm
The automatic calcification alarm is preadjusted at the factory. However, should an adjustment be necessary, proceed
as follows:
H
Measure water hardness or obtain water-hardness range from local water utility company.
H
Disconnect machine from power supply.
H
Open shroud.
H
Remove switch-box cover.
H
Adjust potentiometer on PCB to desired water-hardness range.
H
Screw cover onto switch box.
H
Close shroud and secure.
3.2.7 Decalcifying
Decalcification is normally not required when Wap AntiKalk is used on a regular basis.
Due to improper handling of the machine or the use of unsuitable cleaning agents, deposits can form in the pump
system. The degree of calcification depends on the respective water hardness and is indicated on the pressure gauge
by a gradual increase in the water pressure.
If the working pressure is exceeded by 10 bar (with Variopress device open), the machine must be decalcified.
Procedure:
H
Screw high-pressure nozzle off spray lance and lay separately in Wap decalcifier.
H
SC 720/SC 730 only: Insert free end of cleaning-agent intake hose in container with decalcifier and set metering
valve to maximum concentration.
H
Hold spray lance in separate container to catch escaping liquid.
H
Switch on high-pressure pump.
H
SC 702 only: Operate spray gun and gradually fill water box with decalcifier.
H
Operate spray gun: Decalcifier is sucked in and bubbles heavily as it exits spray lance after approx. 1 minute.
H
Switch off high-pressure pump and allow to work for approx. 15 minutes.
H
Flush out pump system thoroughly with clean water.
H
After approx. 2 minutes an even stream must exit at spray lance. If this is not the case, repeat decalcifying
procedure.
H
Screw high-pressure nozzle onto spray lance.
CAUTION!
Decalcifier causes acid burns. Avoid contact with skin, eyes and clothing, and wear
appropriate protective clothing (e.g. gloves, face protection, apron). Only approved
decalcifiers may be used for decalcifying. Use Wap Decalcifier, No. 8326.
