Check if the water coming out of the relief valve is clean. If it contains debris or
dirt:

-

Open  the  valve  until  the  discharged  water  does  not  contain  debris  or  dirt
anymore.

-

Flush  and  clean  the  complete  tank,  including  the  piping  between  the  relief
valve and cold water inlet.

To make sure this water originates from the tank, check after a tank heat up cycle.

INFORMATION

It is recommended to perform this maintenance more than once a year.

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.

Descaling

Depending  on  water  quality  and  set  temperature,  scale  can  deposit  on  the  heat
exchanger  inside  the  domestic  hot  water  tank  and  can  restrict  heat  transfer.  For
this reason, descaling of the heat exchanger may be required at certain intervals.

Chemical disinfection

If  the  applicable  legislation  requires  a  chemical  disinfection  in  specific  situations,
involving  the  domestic  hot  water  tank,  please  be  aware  that  the  domestic  hot
water tank is a stainless steel cylinder. We recommend to use a non-chloride based
disinfectant approved for use with water intended for human consumption.

NOTICE

When  using  means  for  descaling  or  chemical  disinfection,  make  sure  water  quality
still complies with EU directive 2020/2184.

13.3.1 To drain the domestic hot water tank

DANGER: RISK OF BURNING/SCALDING

The water in the tank can be very hot.

Prerequisite: 

Stop the unit operation via the user interface.

Prerequisite: 

Turn OFF the respective circuit breaker.

Prerequisite: 

Close the cold water supply.

Prerequisite: 

Open  all  the  hot  water  tapping  points  to  allow  air  to  enter  the

system.

1

Remove the top panel, the upper front panel and the lower front panel.

2

Lower the switch box.
