MAINTENANCE
During
operation
the
operator
should
observe that the timer is indicating
proper
cooking
time,
pressure gauge is reading cor-
rectly and steam trap and exhaust valve are
operating
properly
The first
indication
of
defective steam trap operation will usually be
evidenced by uneven
cooking.
If working pro-
perly, the steam temperature
will be even and
cooking will be uniform through the cooking
compartment.
Trouble
may
occur
either
through premature
closing of the steam trap
before all
the
cold air has been exhausted
or
by
its failure
to
close sufficiently
to enable a
proper
steam
pressure build-up.
Either case

the
replacement
of
the
steam trap.
6.3 REPAIR AND REPLACEMENT
WARNING
Be sure to disconnect
120 volt input
power and shut off gas supply before
disassembling
components
and mak-
ing repairs and replacements.
Section
7
of this manual contains a listing
of all replaceable
parts and associated
ex-
ploded views of the Steam-It. In most cases
disassembly
procedures will be obvious from
the exploded
views. Illustrated
disassembly
and assembly
instructions
follow
for pro-
cedures
which
are
not
readily
apparent.
NOTE
Complete
disassembly
of cabinet and
panels are not required. Remove only
the panels or components
required to
make repairs and replacements.
6.3.1 Door Assembly
The door assembly
consists
of the door
latch
and the latch
fulcrum
assembly.
All
parts are replaceable
as shown in Figure
7-4,
Door
Assembly;
Figure
7-5,
Door
Latch;
and
Figure
7-6,
Door Fulcrum and Drain.
6.3.1.1
Gasket
Replacement.
The door
gasket (Figure 7-4 index 6) is readily replaced
by first removing the door assembly from the
cooking
compartment
as
explained
in
paragraph
6.2.1.
The worn gasket is removed
in the same manner as described
for clean-
ing and a replacement
substituted.
A new
gasket which is difficult
to stretch
onto the
door can be made pliable by first soaking it in
hot soapy water. Remounting
the door in the
compartment
completes
the replacement.
6·3
NOTE
The critical
function
of the door seal
makes it imperative
that the gasket be
in good condition.
For this reason it is
recommended
that at least one spare
gasket be kept at all
times.
6.3.1.2
Door Seal Tension
Adju~tment.
An
adjustment
screw is built into the door an-
chor and fulcrum assembly to allow compen-
sation
for
normal
variation
in
gasket
thickness
caused
by
wear.
The adjustment
screw
is shown
in Figure
6-4.
If steam
escapes from around the door, sealing
ten-
sion against
the door opening
can be in-
creased by loosening
the 1/4-20 jam nut and

turning

In-
stallation
of a replacement
door gasket may
result in excessive door latching tension and
require clockwise
adjustment
of the screw.
Trial and error will achieve the screw adjust-
ment which both seals the door against
the
compartment
opening
yet allows
door
lat-
ching with only moderate force applied to the
handle. The final position
is set by holding
the cap screw with
an allen wrench
while
tightening
the 1/4-20 jam nut.

Spring
Replacement.
Should either spring become damaged,
it is
necessary
to replace
both
left
and
right
springs
as a set
(Figure
