Removal
NOTE
To assure a pressure
seal,
the gasket
must be cleaned of soil and
scale,
and
be free of breaks.
6.
Replace
gasket
on
door
and
reassemble
door
assembly
in com-
partment.
Open
and
close
door
several
times
to check
for
correct
operation
and tight
seal of door
in
closed position.
See paragraph
6.3.1.2
to adjust door seal
tension.
6.2.2 Safety Valve Check
The safety
valve is a protective
device
which
automatically
relieves
excessive
pressure
between
15-1/2
and 16
psi,
in the
unlikely
event of equipment
malfunction.
If
the safety valve should leak continually
with
a pressure build-up, or should it cause an in-
terruption
of the cooking
cycle prematurely
(less than 15-1/2
psi on the steam
gauge),
it
must
be assumed
that the safety
valve is
defective
and
be
replaced.
However,
the
steam gauge should first be checked for ac-
curacy
before
making
this
determination.
The steam gauge should register zero with no
pressure
in the cooking
compartment.
If the
normal zero setting
has advanced somewhat
through
usage
(a characteristic
of steam
gauges), the steam gauge should be replac-
ed.

fulcrum
adjustment
screw. These parts are
shown in Figure 7-6.
Periodic
unscheduled
cleaning
of
the
drain
and
plug
assembly
with
detergent-
water solution
will ensure trouble-free
opera-
tion. The drain plug handle and drain hole
must be free of food
particles,
with motion
easy and unrestricted.
The anchor
is equipped
with
a bronze
roller bearing (11) which engages the hooked
door
latch.
The entire
roller
assembly
is
shown
as item (13) in Figure 7-6. The roller
must be cleaned
periodically
to insure free-
moving
operation.
Should
accumulated
dirt
or food
interrupt
normal
rolling,
detergent-
water
solution
should
be used to free
it.
Cleaning
should
be followed
by lubrication
using graphite or other dry lubricant.
6.2.4 Cooking Compartment
A daily cleaning
of the cooking
compart-
ment is required.
Remove pan supports
and
thoroughly
wash and rinse cooker compart-
ment
interior
with
mild soap or aluminum
cleaner. Leave door open when cooker is not
in
use.
See paragraph 3.3 in Section 3.
CAUTION
Do
not
use
strong
detergent
or
abrasive
cleaners.
Pitting of aluminum
interior will result.
6_2.5 General Inspection
Prior
to daily
use the operator
should
visually
inspect
the unit to see that there is
no missing
or detective
hardware,
cracked
glass on pressure gauge, cracked timer
knob,
and that pan supports are properly installed.
