The valve seating must be firmly screwed into the lid (turns clockwise).
The cap is provided with a key to check the fit of the valve.
The inlet valve conforms to the Standard for car tyres.
The working pressure of 2.0 – 2.2 bar is marked with a green line.
This cuts in if the Polyclav is pressurized above the red 2.5 bar mark and releases the excess pressure.

This both locks the lid and acts as a pressure release valve. This double function is an additional safeguard against opening
the Polyclav while under pressure. Undoing the mechanical lid lock at the same time opens a pressure release valve, which
®
effects the pressure balance. If the locking lever and the pressure release valve become too easy or too tight to turn, the
tension on the conical spring may be wrong.
To correct this:
1. Undo the srew in the top of the locking lever
2. Lift off the locking lever
3. Loosen or tighten the tension nut on the spring using an octagonal spanner or flat-nosed pliers.
All handles are packed separately from the Polyclav
The average life of the rubber pressure seal is one year, but can be extended by treating it with talcum powder, glycerol
or Vaseline (petroleum jelly). The rubber pressure seal should never be allowed to dry out in order to avoid abrasion when
opening and closing the Polyclav
®
Changing the seal:
Lift out the old rubber pressure seal from the lugs. Insert the new rubber pressure seal underneath four opposite lugs.
At first the rubber pressure seal will appear to be too big. Seat the rubber pressure seal under all of the lugs making sure
that it is evenly and tightly in position. Greasing the rubber pressure seal with Vaseline will make it easier to seat.
