The optional hand vent valve allows manual air
venting.
To air vent the equipment turn the hand-vent
valve (viewed from top) anticlockwise.
To close the hand-vent valve after air-venting
turn it clockwise.
Fasten the hand-vent valve hand tight.
To operate the manual float-lifting lever a lever

be used to purge any dirt away from the seat area
and out of the equipment by opening the orifice and
draining the liquid.
The cast arrow on the body indicates the correct
direction of rotation.
To open the orifice turn the lever extension from
the tip of the arrow towards the end of the
