4) INCREASE LID TENSION (BY ADJUSTING SPRING BOLT)
CAUTION:
SHOULD BE DONE ONLY AS A LAST RESORT - FIRST CHECK FOR A WORN LID GASKET, A BLOCK-
AGE IN THE SOLVENT FLOW PATH , LOOSE HINGE OR CROSS BAR BOLTS OR A SET POINT THAT
IS TOO HIGH FOR THE SOLVENT BEING RECYCLED.
5) REPOSITION LID and TIGHTEN HINGE AND CROSS BAR BOLTS
The Hinge bolts can loosen over time, causing the lid to shift off center. This can lead to an inadequate
seal and leaking around the Gasket. Loosen the bolts, reposition the lid and re-tighten the bolts.
This procedure tightens the Lid by increasing
the tension on the spring attached to the Lid
Bar Spring Bolt Assembly. The Lid and Bolt
Assembly is carefully designed as a Safety
Pressure Relief system to prevent a danger-
ous build up of pressure inside the closed
tank.
Do not adjust the Spring Holding Nut
by more than 2 full turns maximum.
If 2
full turns do not solve the problem, call for
service.
• While holding the top nut with a wrench,
turn the nut below the spring no more than
a 1/2 turn at a time. Turn in a counter-
clockwise direction (as you look down on
it).
• After each 1/2 turn, operate the unit nor-
mally and check for leaks.
