PRESSURE CONTROL SWITCH ADJUSTMENT
A
B
If boiler fails to maintain steam pressure in operating
range, pressure control switch may require adjustment.
1. Start boiler and allow pressure to build up to operating level - 15 PSI (1kg/cm²).
2. Check boiler pressure gauge. If gauge indicates 12
to 14 PSI, pressure control switches are properly adjusted.
3. If boiler does not come on when pressure gauge
reads 7 PSI and does not go off when pressure gauge
reads 14 PSI, proceed as follows:
WARNING
Because power must be on to adjust pressure
switches, be sure to protect against electrical
shock.
a. Remove screw and lift front cover off control box.
b. Hand adjust operating pressure control switch
and high limit pressure control switch by turning adjusting nut (Knurled knob) clockwise to
raise and counter clockwise to lower actuation
point. Switch should be set so that boiler comes
on when boiler pressure gauge reads 12 PSI
and goes off when gauge reads 14 PSI. Switch
should be set so that boiler will shut off if pressure reaches 15 PSI.
WARNING
Because power must be on to adjust pressure
switches, be sure to protect against electrical
shock.
1. Check that the (2) different switches are actually
used.
2. Set high limit switch H15 all the way to maximum at
15 PSI.
3. Set operating control switch F15 ON at 10 PSI, OFF
at 12 PSI.
When unit is properly operating, switch F15 will shut boiler off at approximately 14 PSI and turn back on at approximately 11 PSI.
Also, switch H15 will cause low water light on boiler control box (under cabinet) to come on due to reaching high
pressure.
c. The actuation value (differential) is factory set
and cannot be changed.
d. Repeat steps, 1, 2, and 3. If 45 to 14 PSI boiler
pressure gauge reading is obtained during boiler
operation, adjustment is correct. If proper adjustment cannot be made consult Trouble-Shooting
Guide in this manual.
e. After making adjustments, replace cover on pres-
sure switch box and screw.

COLD WATER CONDENSER & LID COUNTERBALANCE ADJUSTMENT
COLD WATER CONDENSER ADJUSTMENT
The function of the cold water condenser is to keep
the temperature in the drain line from exceeding 150°F
(66°C). Solenoid valve (see Figure 4) controls the water
ow to the cold water condenser. The valve opens and
runs cold water through the drain until the temperature
drops below 150°F (66°C). The water ow may be regulated by adjusting thermostat dial.
The valve has a built-in water strainer which should be
removed and periodically cleaned.
LID COUNTERBALANCE ADJUSTMENT
The kettle lid is equipped with a torsion spring counterbalance device to assist in lid lifting and to prevent slam-
ming. The device is shown assembled in gure 5 (internal
cabinet, side view) and exploded in gure 0 (hinge and lid
assembly). If lid slams closed when handle is released,
spring tension should be increased. If lid lifts up or refuses to remain down on kettle, tension should be reduced.
To adjust spring tension, proceed as follows:
1. Lift cover to open position.
2. Pull down on piston assembly to release it from its
position. Rotate “T” bar clockwise to increase tension,
continue clockwise to reduce tension.
3. Operate lid several times. Repeat step 2 until desired
operation is obtained.
4. Hold hex head screw rmly in position and tighten
hex nut to lock adjustment.

WATER LEVEL CONTROL ADJUSTMENT
Circuit Operation
Boiler water level is controlled by rising and falling water
level which makes and breaks circuits between two different length probe electrodes inside boiler and the grounded boiler wall.
The short probe is used to turn water on and off as required. The long probe is used to cut off power to the
heating elements and give a signal alarm when water is
too low.
A secondary low water cut-off is used as a warning device
to dry ring and serves as a warning device to delime/
descale boiler.
Water Level Control Operation
Starting with an empty boiler, switch S1 is closed to start
the following sequence.
1. Solenoid R-1 energizes allowing water to ow into
boiler. At the same time, the primary circuit of T-1 is
energized.
2. Boiler continues to ll until water level reaches tip of
electrode probe A completing the secondary circuit of
T-1 and energizing C-3.
3. When C-3 is energized, NC (normally closed) contact
opens which de-energizes R-1 and stops water ow.
NO (normally open) contact closes completing circuit
to probe B.
As water boils away below the end of probe B, the following occurs:
1. Secondary circuit of T -1 is broken and C-3 de-energizes.
Water Level Control Maintenance & Cleaning
The water level is controlled by two probes mounted on
the top of the boiler or on front of the boiler. Inspection
should be done at least two times a year as determined
by local water conditions. Probe electrodes must be as
free of scale and sludge build-up as possible to insure
proper functioning of water level control system.
Electrode lengths must be checked to insure proper water
level settings.
If probe electrodes and housing appear to have little or
no build-up of scale or sludge, use Market Forge Total
Concept Chemical Cleaner Descaler (p/n 20-0307) for
this minor cleaning. This type of cleaning should be done
at least twice a year (refer to page 25 for complete Total
Concept Application Instructions)
Probe Cleaning
The following procedure should be followed for cleaning
probes when build-up is considerable (at least once a
year):
1. Clean both probes, in detergent and water using a nylon brush for scrubbing. Rinse thoroughly in clear water. If scale and sludge build-up has been removed,
and reinstall. If probes are not clean, proceed to step
#2 and #3.
2. Use emery cloth or sandpaper to remove scale from
probes. Rinse thoroughly in clear water.
3. A U.S.D.A. approved boiler cleaner may be used for
more thorough cleaning of probes.
2. When C-3 de-energizes, NO contact opens to break
circuit to probe A while NC contact closes which en-
ergizes R-1 and allows boiler to ll.
Low Water Cut-Off
When S-1 is closed, the following also occurs:
1. Primary circuit of T -2 is energized.
2. When water level reaches probe C and S-2 is momentarily closed, C-4 is energized.
3. When C-4 is energized, NO contacts close completing low water cut-off circuit through contacts 7 and 8
and completing circuit through contacts 3 and 4 energizing C-1 and C-2 which closes heater circuit.
If water drops below probe C, the following occurs:
1. Secondary circuit of T-2 breaks and C-4 de-energizes. Contact 7 and 8 and 3 and 4 open to break circuit
to C-1 which opens circuit to heating elements.
C-1 and C-2 will not operate until water level in boiler
is normal and S-2 is momentarily closed.

DRAW-OFF VALVE REPAIR
Common Leak Repairs
To repair a valve leak, the source must rst be determined. Leaks from around the valve steam are corrected
by replacing the rubber "0" ring. Dripping from the valve
outlet which occurs with the valve tightly closed indicates
faulty seating of the valve disc (pan of 6) against the valve
seat. Dripping is often corrected by cleaning residue from
disc and seat using very ne emery.
Valve Seat Lapping
If either the disc (pan of 6) or seat is found damaged, it is
necessary to either replace the entire valve or perform the
lapping procedure as follows:
1. Disassemble valve and clean both disc and valve
seat.
2. Attach handle (2) to stem with valve bonnet (4) removed.
3. Apply a good grade of ne lapping compound to disc
and inset it into valve to make light contact against
seat.
4. Rotate stem disc against seat by turning handle. This
rotation allows stem to wobble in space the bonnet
would normally occupy. Continue with light pressure
until compound dries.
5. Reassemble and test for leaks with valve closed. If
dripping occurs, repeat lapping procedure as many
times as required to obtain a water-tight seal.

TILTING MECHANISM REPAIR
MT40EO tilting kettles are equipped with tilting mechanisms.
Lift Screw Assembly Removal
The assembly is removed with the kettle in the lowered
position. Assembly removal proceeds as follows:
1. Remove the two bolts which hold ball nut assembly in
screw lever (7).
2. Remove the two 5/16" hex head cap screws which
fasten the screw housing to cabinet frame.
3. Lift screw assembly from cabinet.
NOTE: Proceedin reverse order to replacethe assem-
bly.
General Inspection & Cleaning
The screw assembly should run smoothly throughout
the entire stroke. If operation is not uniform, remove the
screw assembly (see Saginaw screw assembly removal)
and proceed as follows:
1. Inspect screw shaft for accumulation of foreign matter
in the ball grooves.
2. Using cleaning uid or solvent, remove dirt from ball
grooves. Be sure to ush the ball nut assembly thoroughly.
Lift Screw / Tilting Mechanism
The driving end of the Lift Screw is formed into a slotted
sleeve which receives the engagement pins of the removable hand crank.
The Lift Screw assembly must be removed from the kettle
to complete installation. The collar is removed by driving
out the roll pin which secures it to the screw shaft. The
replacement sleeve slides over the faulty shaft end and
is fastened with a roll pin. The repair is completed by remounting the Saginaw Screw assembly.
Tilting Mechanism Lubrication
Lubrication of the tilting mechanism is the only required
preventive maintenance other than daily cleaning. Inspect the screw of the tilting mechanism annually for
adequate lubrication. If screw appears "dry", apply good
grade bearing grease directly on the threads so that the
threads appear to be barely damp. If mechanism fails to
run smoothly.
3. Cycle the ball nut along the screw shaft several times.
Then, wipe with a dry, lint less cloth and lubricate immediately.
