CAUTION
If you are replacing the diaphragms, you must rein-
stall the air valve before installing the diaphragms, as
the diaphragms will force the pilot pins into the air
valve area.
The pilot pins (26) must give clearance for the actua-
tor link (16 ), to prevent damage to the pins. Follow
steps 13–15 carefully.
13. Check if either of the two pilot pins (26) are pro-
truding out into the air valve cavity. Push them
back in as far as possible.
14. If one of the pins is still protruding, make sure the
air valve is shifted away from that pin's side of the
cavity. To shift the valve, push down on the detent
link (22) and slide it to the other side with your
fingers (see Fig. 11).
15. Align the air valve assembly (A) so the reset shaft
(21) is at the top and the valve is angled away
from a protruding pilot pin (26), then slip it into
position. See Fig. 10. Do not force the air valve
down onto the pin. If the pin is interfering with
the actuator link (16), make sure the valve is
shifted away from the pin (see step 14), then
reposition the valve.
NOTE: This example shows how to shift the air valve when a pilot pin (26) is protruding as shown in Fig. 10. If the
pin on the other side of the air valve is protruding, the valve should be shifted in the reverse of this example.
