Check the heater 

Check the heater annually for external 
and internal corrosion damage. 

If corrosion damage can be seen, check 
the heater at once for continued usability.

 

 

Cleaning the heater 

NOTICE 

Deposits in the heater 

The heater will be destroyed 

►

  Remove sludge sediments in the heater on a regular basis. 

If sediments are not removed, a heat build.up will form which could cause the 
heating elements to burn out. 

 

Rinse out the sediments in the lower part of the container. Remove sediments which 
cannot be removed either by rinsing them out manually or by dissolving them. 

Take care to ensure the heating elements do not suffer any mechanical or cleaning 
agent damage while they are being cleaned. No warranty protection is provided for 
mechanical damage or damage caused by corrosion.
