SECTION IV
MAINTENANCE / SERVICE
(4) If excessive force was required to open pres-
sure relief valve (2), replace the pressure relief
valve (Refer to para 4.23).
NOTE
If the pressure relief valve does not close completely
when the wire ring is released, pull the wire ring again
and release it quickly so the valve snaps back into
position. Do this until the valve seats properly.
(5) Release wire ring of pressure relief valve (2).
The steam should vent out of the pressure relief
valve until the wire ring is released. When the
wire ring is released, the valve should seat,
stopping the release of steam.
(6) If the pressure relief valve (2) will not re-seat
properly, replace the pressure relief valve (Refer
to para 4.23).
(7) Install top inspection cover (1).
4.26 Pressure Relief Valve Check
(1) Remove the top inspection cover (1,
Figure 4-31).
WARNING
Refer to the operator manual for
complete instructions on operating the
sterilizer. Failure to do so could result in severe
personal injury.
(2) Select the UNWRAPPED cycle and start the
cycle.
DANGER
Pressure Relief Valve will be hot.
Use a screwdriver or rod to pull the
wire ring. Do not pull the wire ring with bare
hands or burns will result. Steam will be vented
from under the rear of the sterilizer. To keep from
being burned, place a steam barrier (a rolled up
towel) around the bottom of the sterilizer.
(3) When the “heat up” portion of the cycle is
complete and the elapsed time is being counted
down on the display PC board, pull on wire ring
of pressure relief valve (2) with a screwdriver.
