Check Valves Replace If Necessary - Arjohuntleigh Malibu Sovereign Maintenance And Repair Manual

MRM Malibu/Sovereign
SP 6. Check Valves, Replace if
Necessary
NOTE
Before replacements and service, shut off all
water supply.
RPE SOLENOID VALVES These valves are
replaced complete if not functioning. They have
an expected lifetime of 100000 openings and
closings. See page 50.
OLD SOLENOID VALVE (Fill valve)
The solenoid valves has a membrane as well as
an anchor seal.
Membrane
The membrane (4) is located underneath the
brass lid (2) and is accessed after removing the
four Allen head screws.
When removing the lid; note the position of the
membrane as there is a small bleed hole and
brass pipe in the membrane (A) that has to be
assembled correctly to function.
The membrane is also equipped with a pressure
transition hole (B), allowing the pressure to
build up on top of the membrane thus keeping
the valve closed.
As the transition hole has to be clear of all
obstacles and dirt to function satisfactory, the
hole has an inserted brass pipe (very small) to
prevent lime build ups. This pipe must not be
removed or the result will be that the valve does
not close.
Anchor seal
The anchor seal on the anchor (6) is located
under the anchor housing (7) and is reached by
loosening and removing the solenoid (1) and the
anchor housing. Be careful not to loose the
anchor spring on the anchor.
The service kit for this valve includes position
4, 5, 6 and 7.
Membrane condition
Focus should be on the membrane rubber status:
it should not stain your fingers when touching it
or show signs of deterioration. Clean off all
surfaces with a rough cloth or similar before
reassembling the valve.
