Operations and Maintenance Manual

7.3
Door
Remove the stop from the door post end
and the handwheel
retaining ring.
Then,
unscrew
the
handwheel,
exposing
the
bearing and screw threads.
Grease these
parts
liberally,
with
a
high-temperature
grease such as lubriplate 930AA.
To disassemble the door, follow these steps:
1.)
Remove the three door post screws
on the inside of the door and knock
out the door post.
2.)
Rotate the hub
until the arms
are
clear of the fulcrums and the entire
assembly lifts off.
Assembly
of the door
is a reversal
of the
preceding procedure.
Ensure that the holes
in the hub flange line up with the peg in the
door to permit the door to be locked.
The O ring under the door post should be
replaced when the door post is refitted.
To
replace the door gasket, simply lubricate it
with
soap
and
water.
Lay
the gasket
in
place and push it into the groove wit the
fingers of four equal-distant points.
Then,
carefully work
the
gasket
into the groove
until it is evenly distributed around the door.
Working from one point results in too much
of too little gasket left over at the opposite
end.
The
hinge
pins should
be greased
at the
same time that the door is greased, with the
same
lubricant.
First,
loosen
the
allen
screws
in the
hinge
blocks,
and
drive
the
pins
out with
an
aluminum
or brass
drift.
Grease the pins and replace.
Then, tighten
the allen screws.
7.4
Carrying Case
Periodically, lubricate the hinges and latches
on the case with a few drops of light motor
oil.
This ensures good performance.

PREPARATION FOR SHIPPING OR
STORAGE
Wash the interior of the shell surface with a
mixture
of
30%
Trisodium
Phosphate
in
water.
DO
NOT
use
an
abrasive
cleanser.
All shelving and exposed interior surfaces of
the
case
should
be
cleaned
in
the
same
manner.
Clean the chamber drain plug and
remove
all
lint
and
sediment
from
the
strainer.
With
the sterilizer doors
open,
tum
the
operating valve to the sterilize position and
open the jacket drain valve.
Gently rock the
sterilizer from side to side and from end to
end to ensure removal of all water from the
jacket, chamber, and piping.
