NOTE:
Older steamer models have a movable blade.
When closed, the blade reacts as a guillotine that
should be free to move fully down into the valve pocket
(projection at bottom of valve) so that the pierced hole
in the blade aligns perfectly with the body opening.
1.
Remove and disassemble the valve as follows:
A.
Remove two screws and inlet port of valve
body.
B.
Unthread and remove the plunger tube.
C.
Remove the plunger and valve blade.
D.
Remove the plastic seat from the valve
body.
2.
Inspect the valve:
•
The blade must be clean.
•
The blade mating surfaces of the plastic
seat members must be flat and undamaged.
•
The plunger and plunger tube must be
clean.
•
The plunger must slide freely in the tube.
•
The compression spring which fits in the
hole in the top of the plunger must be clean
and move freely.
WATER ACCUMULATING IN COMPARTMENT
Water accumulation on the bottom of the cooking
compartment(s) is primarily condensed steam. Failure
to drain out quickly and completely may be due to:
•
Debris in the compartment drain screen.
•
Improper leveling of the steamer.
To clean the drain screen:
1.
Pull it out of the cooking compartment.
2.
Thoroughly clean it until no debris remains.
3.
Reinstall it in the cooking compartment..
COOKING CYCLE CANNOT BE ACTIVATED
When the power switch on boiler control box is ON,
set the timer knob to 2 minutes. Both READY lights
should go off, COOKING lights should come on and
steam should be entering both compartments. If that
does not occur, inspect all wire terminations to ensure
they are properly connected and secure.
INTAKE SHUT-OFF VALVE ADJUSTMENT

The intake shutoff valve controls the amount
of steam supplied to steam control solenoid valve.
1.
Remove right side control panel.
2.
Open the intake shut-off valve (Fig. 16)
completely.
3.
If the steamer ready light is on, then proceed to

Turn both cooking timers on and allow boiler to
cycle 2 to 3 times, then proceed to Step 7.
6.
Turn both cooking timers on.
7.
Monitor the boiler until heat source turns off.
NOTE:
Adjust the valve when the boiler pressure is
at the upper cycling limit.
8.
Adjust the intake shut-off valve until the manifold
pressure gauge reads 9 ±1 psi.
9.
Monitor gauge reading 1 to 2 cycles to ensure
pressure is set correctly.
10. Once the valve is set:
A.
Turn both cooking timers off.
B.
Reinstall right side control panel.
