Checking indicator lights
Check the operation of the indicator lights.
• Briefly switch on the ultrasound.
» The green indicator light will remain lit as long as the ultrasound is switched on.
• Switch on the heater briefly with the rotary knob set to above 30 °C.
» The white and yellow indicator lights will remain lit as long as the heater is
switched on.
Checking the output of the ultrasound and the heater
The output can be checked with a wattmeter between the device mains plug and the socket.
Procedure
1. Fill the tank with water.
2. Switch the ultrasound and, if present, the heater on and off, one after the other.
Read the output.
3. Compare the readings with the technical data. See chapter
.
The measured values may deviate from the values in the technical data by a maximum of
± 20%.
Checking the float switch
The float switch is situated in the tank and is therefore a wear part. The function
and tightness of the float switch must be inspected at regular intervals.
When the tank is full, the float must float up to the top stop (top ring).
A check can be carried out in the empty tank as follows:
Procedure
1. Fill a sufficiently large cup with water.
2. Slide the cup over the float from below.
Results
» The float float floats up – part OK.
» The float sticks to the lower stop ring – part must be replaced.
Contact the manufacturer.
