Size the discharge outlet so that water can drain off unim-
peded when the safety valve is fully opened.
Ensure that the drain hose of the safety valve is open to the
outside.
Install the drain hose of the safety valve with a constant fall
to the drain. When installing the drain, never kink the drain
hose.
Secure the drain hose by suitable means, to prevent any hose
movement in the event of water being discharged.

WARNING Electrocution
Carry out all electrical connection and installation work
in accordance with national and regional regulations.
WARNING Electrocution
The connection to the power supply must be in the form
of a permanent connection. Ensure the appliance can
be separated from the power supply by an isolator that
disconnects all poles with at least 3mm contact separa-
tion. This requirement can be met with contactors, circuit
breakers, fuses/MCBs, etc.
WARNING Electrocution
Before working on the appliance, isolate it from the
power supply at the control panel.
Note
The specified voltage must match the mains voltage. Ob-
serve the type plate.
Note
Observe the operating and installation instructions of the
heat pump manager and the heat pump.
The connection must only be carried out by a qualified contractor
