Magnetic filter/dirt separator
NOTICE
The optional magnetic filter/dirt separator requires yearly maintenance. Follow the
instruction of the manual of the optional equipment.
Water pressure relief valve
Open the valve and check if it operates correctly. The water may be very hot!
Checkpoints are:
▪ The water flow coming from the relief valve is high enough, no blockage of the
valve or in between piping is suspected.
▪ Dirty water coming out of the relief valve:
- open the valve until the discharged water does NOT contain dirt anymore
- flush the system
It is recommended to do this maintenance more frequently.
Switch box
▪ Carry out a thorough visual inspection of the switch box and look for obvious
defects such as loose connections or defective wiring.
▪ Using an ohmmeter, check if contactors K1M, K2M, K3M and K5M (depending on
your installation) operate correctly. All contacts of these contactors must be in
open position when the power is turned OFF.
WARNING
If the internal wiring is damaged, it has to be replaced by the manufacturer, its
service agent or similarly qualified persons.
