Error code Detailed error
code Description
UA 17 Tank type problem
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.
Minimum required flow during heat pump operation
04 models Heating 6 l/min
Cooling 6 l/min
08 models Heating 6 l/min
Cooling 10 l/min
11 models Heating 10 l/min
Cooling 15 l/min
16 models Heating 10 l/min

Minimum required flow during defrost operation
04+08 models 12 l/min
11+16 models 15 l/min
Minimum required flow during backup heater operation
All models 12 l/min
If the 7H‑01 error persists, the unit will stop operation and the user
interface will display an error code that needs to be reset manually.
Depending on the problem, this error code is different:

Additionally, this error code might
be an indication of frost damage
to the plate heat exchanger. In
that case, contact your local
dealer.

a normal tank heat-up.
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 Bringing the system to a specialized treatment facility.
INFORMATION
For more details, see the service manual.
13.2 To pump down
Example: To protect the environment, pump down when relocating
the unit or when disposing of the unit.
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 cap from the liquid stop valve and the gas
stop valve.
