INFORMATION
In case of error code AH and no interruption of the
disinfection function occurred due to domestic hot water
tapping, following actions are recommended:
▪ When the Domestic hot water > Type > Reheat or
Reheat + sched. is selected, it is recommended to
program the start-up of the disinfection function at least
4 hours later than the last expected large hot water
tapping. This start-up can be set by installer settings
(disinfection function).
▪ When the Domestic hot water > Type > Scheduled only
is selected, it is recommended to program a Storage
eco 3 hours before the scheduled start-up of the
disinfection function to preheat the tank.
NOTICE
When the minimum water flow is lower than described in
the table below, the unit will temporarily stop operation and
the user interface will display error 7H‑01. After some time,
this error will reset automatically and the unit will resume
operation.
INFORMATION
Error AJ-03 is reset automatically from the moment there is
a normal tank heat-up.
INFORMATION
In case of an E7‑62 error, brine pump operation stops due
to not enough flow in the brine circuit. If 10‑day brine pump
operation is running, it will stop running and will only
resume once the error is reset. It is only possible to reset
the error with the domestic hot water home screen or the
leaving water temperature home screen turned ON. To
reset the error, press
and confirm by pressing .
INFORMATION
If an U8‑04 error occurs, the error can be reset after a
successful update of the software. If the software is not
successfully updated then you must make sure that your
USB device has the FAT32 format.
INFORMATION
How an error code can be reset will be displayed on the
user interface connected on the indoor unit.
13 Disposal
NOTICE
Do NOT try to dismantle the system yourself: dismantling
of the system, treatment of the refrigerant, oil and other
parts MUST comply with applicable legislation. Units
MUST be treated at a specialised treatment facility for
reuse, recycling and recovery.
13.1 Overview: Disposal
Typical workflow
Disposing of the system typically consists of the following stages:
1 Pumping down the system.
2 Performing vacuum drying.
3 Bringing the system to a specialized treatment facility.
INFORMATION
For more details, see the service manual.
13.2 To pump down
DANGER: RISK OF EXPLOSION
Pump down – Refrigerant leakage. If you want to pump
down the system, and there is a leak in the refrigerant
circuit:
▪ Do NOT use the unit's automatic pump down function,
with which you can collect all refrigerant from the
system into the outdoor unit.
Possible consequence:
Self-combustion and explosion of the compressor
because of air going into the operating compressor.
▪ Use a separate recovery system so that the unit's
compressor does NOT have to operate.
NOTICE
During pump down operation, stop the compressor before
removing the refrigerant piping. If the compressor is still
running and the stop valve is open during pump down, air
will be sucked into the system. Compressor breakdown or
damage to the system can result due to abnormal pressure
in the refrigerant cycle.
Pump down operation will extract all refrigerant from the system into
the outdoor unit.
1 Remove the valve lid from the liquid stop valve and the gas stop
valve.
2 Install a manifold on the gas stop valve.
3 After 5 to 10 minutes (after only 1 or 2 minutes in case of very
low ambient temperatures (<−10°C)), close the liquid stop valve
with a hexagonal wrench.
4 Check on the manifold if the vacuum is reached.
5 After 2-3 minutes, close the gas stop valve and stop forced
cooling operation.

13.3 To activate/deactivate the vacuum
mode field setting
To perform vacuum drying of the outdoor unit’s internal refrigerant
piping it is necessary to activate the vacuum mode. This will open
required valves in the refrigerant circuit so the vacuuming process
can be done properly.
To activate vacuum mode:
