• For stainless steel pipe connections, place union nut and clamping ring onto the pipe and let
protrude approx. 10mm.
• Push the pipe into the valve up to the stop.
• Tighten the union nut at first fingertight.
• In case of first assembly, then tighten the union nut 1 1/4 turns more
• In case of re-assembly, tighten 1/4 turns more.
• When connecting PE/PTFE lines to stainless steel valves, insert stainless steel support sleeve
into the plastic line in addition.
Support sleeve for hose 6 x 4 mm
Support sleeve for hose 8 x 5 mm
Support sleeve for hose 12 x 9 mm
Cut the free suction line end such that the subsequently installed foot valve is positioned shortly
above the bottom of the tank – for metering solutions with contaminations or sediment at least
50mm above the tank bottom.
IMPORTANT
Always cut the suction line to the required length and route as riser!
For the material type "PV", a vent valve (9) is included. In this case, a hose line with an inner
diameter of 4 – 5mm must be slipped on the bypass hose grommet (10) and the other end of the
hose must be returned to the metering tank; preferably use PVC soft 6 x 4mm.
For PE lines, this is e.g. to be secured against coming lose using an instant cable fastener.
In this case, also connect the pressure line to the pressure connection and the metering valve.
Open the vent valve (9) by turning the star handle anti-clockwise – the way for the coarse suction
ventilation via the bypass is now open.
For liquid ends without vent valve, only connect the pressure line to the liquid end but not to the
metering valve!
