INLET & OUTLET
We strongly recommend the use of flexible hoses to
connect the appliance to the water distribution system; use
hoses with a large diameter in order to limit the pressure
loss.
We strongly recommend the installation of a bypass
system (not included with this product!) to isolate the
appliance from the water distribution system in case of
repairs. It allows to turn off the water to the appliance, while
maintaining full-flow (untreated) water supply to the user.
only for PF-GAC1 & PF-AG1:
with factory bypass (optional)

1. Screw the factory bypass onto the in/out ports on the
control valve (❖&); make sure to install the gasket
seals. Tighten the nuts firmly by hand.
2. Screw the connection kit with nuts onto the factory
bypass (&); make sure to install the gasket seals.
Tighten the nuts firmly by hand.
3. Connect the mains water supply to the adaptor on the
inlet port of the factory bypass ().
4. Connect the application to the adaptor on the outlet port
of the factory bypass ().
only for PF-GAC1 & PF-AG1:
with 3-valve connection kit (not included)

1. Install the 3-valve connection kit.
2. Screw the connection kit with nuts onto the in/out ports
on the control valve (&❖); make sure to install the
gasket seals. Tighten the nuts firmly by hand.
3. Connect the IN valve of the 3-valve connection kit to the
adaptor on the in port of the control valve ().
4. Connect the OUT valve of the 3-valve connection kit to the
adaptor on the out port of the control valve (❖).
5. Connect the mains water supply to the inlet of the 3-valve
connection kit.
6. Connect the application to the outlet of the 3-valve
connection kit.
only for PF-GAC1,5 & PF-AG1,5:
with 3-valve connection kit (not incl.)
Picture 3
= inlet of control valve (untreated water)
❖ = outlet of control valve (treated water)
1. Install the 3-valve connection kit.
2. Insert the adaptors in the in/out ports on the control valve
(&❖); make sure not to damage the O-rings. Install the
nuts and tighten them firmly by hand.
INSTALLATION
3. Connect the IN valve of the 3-valve connection kit to the
adaptor on the in port of the control valve ().
4. Connect the OUT valve of the 3-valve connection kit to the
adaptor on the out port of the control valve (❖).
5. Connect the mains water supply to the inlet of the 3-valve
connection kit.
6. Connect the application to the outlet of the 3-valve
connection kit.
We recommend the use of a stand pipe with P-trap.
To prevent backflow from the sewerage system into the
appliance, always ensure sufficient air gap between the end
of the drain hose or pipe and the sewerage system.
Lay-out the drain hose 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.
only for PF-GAC1 & PF-AG1
Picture 6
1. Connect the 19 mm hose to the drain connection of the
control valve (); secure it by means of the clamp.
2. Run the drain hose to the sewerage system and connect
it, ensuring sufficient air gap between the end of the hose
and the sewerage system. This drain line operates under
pressure, so it may be installed higher than the appliance.
only for PF-GAC1,5 & PF-AG1,5
Picture 7
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.
Picture 8
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 ().
