Installation & Commissioning - Softena SOF-POE-1 Instructions D'installation Et D'emploi

INLET & OUTLET

Always mount the appliance with the inlet/outlet in
horizontal position and the drain outlet pointing
downwards.

Make sure that the pipe in which the appliance will be
mounted, is properly attached to the wall, in order to
support the weight of the appliance.

The bottom section of the appliance (transparent
housing and below) can be rotated freely; this way the
orientation of the inlet/outlet ports and the position of the
drain handle/motor can be adjusted to suit the installation
location.

Make sure to shut off the water supply to the place of
installation, before you start any plumbing work.

1. Screw the connection kit with nuts onto the inlet and
outlet ports of the appliance; make sure to install the
gasket seals. Tighten the nuts firmly.
2. Install the appliance in the water pipe.
3. Connect the mains water supply to the inlet port marked
'IN' of the appliance.
4. Connect the house/application to the outlet port marked
'OUT' of the appliance.
DRAIN

only for SOF-POE-1: the rinse water that flows from the
drain outlet when backwash is performed, may be collected
in a suitable removable recipient (f.e. a bucket) or
discharged via a permanent connection to the sewerage
system.

only for SOF-POE-2: a permanent connection to the
sewerage system must be provided for the discharge of the
rinse water that flows from the drain outlet when backwash
is performed automatically.

In case of a permanent connection to the sewerage
system, we recommend the use of a stand pipe with P-trap.
The connection must be made in such a way that backflow is
prevented. Make sure that the sewerage system is suitable
for the rinse water flow rate of the appliance.

flow meter remains properly connected.
2. Connect the cable from the electronic controller to the
cable on the drain motor; secure the connection.
3. Plug the transformer into an electrical outlet.

Whenever the electronic controller or the power supply
is (re)connected to the appliance, the drain motor will
automatically be activated and run until it reaches the
service position, i.e. drain is closed.
