3. Screw the PVC elbow () onto the adaptor at the out port
of the control valve (); use an appropriate sealant.
4. Insert the adaptors in the in/out ports on the flow meter
(&); make sure not to damage the O-rings. Install the
nuts and tighten them firmly by hand.
5. Screw the flow meter () into the PVC elbow (); make
sure to respect the flow direction (see indication arrow);
use an appropriate sealant.
6. Connect the flow meter cable from the control valve to
the flow meter; secure it by means of the screw.
7. Screw the Service Valve () onto the adaptor on the out
port of the flow meter (); make sure to respect the flow
direction (see indication arrow on the bottom of the
Service Valve); use an appropriate sealant.
8. Connect the IN valve of the multiple valve connection kit
to the adaptor on the in port of the control valve ().
9. Connect the OUT valve of the multiple valve connection
kit to the outlet of the Service Valve ().
10. Repeat steps 2-8 for both Simplex systems.
11. Connect the mains water supply to the inlet of the
multiple valve connection kit.
12. Connect the application to the outlet of the multiple valve
connection kit.
DRAIN

We recommend the use of a stand pipe with P-trap.

To prevent backflow from the sewerage system into the
appliance, always install and use an air gap (drain adaptor
with air gap included with PF-SOF1), to connect the drain
hoses to the sewerage system.

Always use separate drain hoses for the control valve(s)
(discharge of rinse water) and the brine tank overflow.

Lay-out the drain hoses in such a way that pressure loss
is minimized; avoid kinks and unnecessary elevations.

Make sure that the sewerage system is suitable for the
rinse water flow rate of the appliance.

1. Install the drain adaptor to the sewerage system; it fits
over a 32 mm pipe or inside a 40 mm pipe adaptor. Ensure
a permanent and watertight connection.
2. Connect a 13 mm hose to the drain connection of the
control valve (); secure it by means of a clamp.
3. Run the drain hose to the drain adaptor and connect it to
one of the hose barbs; secure it by means of a clamp. This
drain line operates under pressure, so it may be installed
higher than the appliance.
4. For Duplex: repeat steps 1-3 for both Simplex systems.

1. Connect a pipe to the 1" BSP Male drain connection of the
control valve (); use an appropriate sealant.
2. Run the pipe to the sewerage system and connect it,
ensuring sufficient air gap between the end of the pipe
and the sewerage system. This drain line operates under
pressure, so it may be installed higher than the appliance.
INSTALLATION
3. For Duplex: repeat steps 1-2 for both Simplex systems.

PF-BTA: brine tank assembly (optional)

1. Install the air gap to the sewerage system; it fits over a
32 mm pipe or inside a 40 mm pipe adaptor. Ensure a
permanent and watertight connection.
2. Connect a 13 mm hose to the overflow elbow on the brine
tank; secure it by means of a clamp.
3. Run the drain hose to the air gap and connect it to one of
the hose barbs; secure it by means of a clamp. This drain
line does NOT operate under pressure, so it may NOT be
installed higher than the brine tank.

1. Plug the DIN plug on the connection cable of the Service
Valve into the DIN socket at the back of the electronic
timer head of the respective control valve ().
