Damage to the appliance and the environment
In dual mode operation, the return water of the second
heat source can flow through the heat pump. Please note
that the return temperature must be no higher than 60 °C.
4. Settings
The system is operated exclusively with the heat pump manager
(WPM 3).
Observe the heat pump manager operating and installation
instructions.
5. Maintenance and care
!
Damage to the appliance and the environment
Maintenance work, such as checking the electrical safety,
must only be carried out by a qualified contractor.
A damp cloth is sufficient for cleaning all plastic and sheet steel
parts. Never use abrasive or corrosive cleaning agents.
Check the condensate drain monthly (visual inspection). Remove
contaminants and blockages immediately (see chapter “Position-
ing”).
!
Damage to the appliance and the environment
Keep the air discharge and intake apertures free from
snow and leaves.
We recommend an annual inspection (establishing the actual
state) and, if required, maintenance (returning the set state) by a
specialist contractor.
6. Troubleshooting
Störung Ursache Behebung
The external unit
leaks water.
The condensate drain may be
blocked.
Clean the condensate
drain as described
in chapter ‘Care and
maintenance’.
This can cause the
humidity in the
outdoor air to ac-
cumulate as dew
or frost on the
cooled heat pump
casing
The heat pump is drawing heat
from the outdoor air to heat the
building. This can cause the humid-
ity in the outdoor air to accumulate
as dew or frost on the cooled heat
pump casing. This is not a defect.
Note
Even when the condensate is draining away correctly,
expect water to drip from the appliance onto the floor.
If you cannot remedy the fault, notify your heating contractor. To
facilitate and speed up your enquiry, please provide the serial
number from the type plate. The type plate is located on the front
at the top on the right or left hand side of the casing.
