Adjusting The Hood Pressure Switch - Wexiodisk WD-12S Installation And User Manual

Installation instructions

3.5.8 Adjusting the hood pressure switch

Hood function should be checked before beginning installation of the pressure
switch. The hood should open and close with a smooth movement.
It is important that the machine is evenly balanced for optimal operation of the
hood.
Run the machine through one wash so that water reaches the sliding surface of
the hood. This will mean that hood function should now operate normally.
Adjusting the pressure switch:
1.
2.
3.
Make sure you do not set the pressure switch to turn off too easily. This could
mean that the pressure switch will break if, for example, there is too much dirt on
the sliding surface of the hood, or the hood is stiff for any reason, causing it to not
go down.

Unscrew the adjuster screw on the pressure switch (1) to length a,
approximately 10-11mm.
Push the hood down to around 10cm above the edge of the tank, and use
your hand (in the middle of the hood) to hold it there. When the anti-
crushing mechanism is correctly installed, the hood should automatically
stop and go up again when the pressure reaches around 12kg. This can be
checked by, for example, using scales (such as fish weighing scales or
dynamometer).
Tighten the screw a quarter of a turn and repeat the test. The pressure
switch is usually adjusted correctly when length a = approximately 12mm.
One revolution of the screw is equivalent to around 1mm. If the screw is
tightened (turned clockwise) the pressure switch will become more
sensitive and turn off more easily, and vice versa.
