TROUBLESHOOTING
EXTREMELY SLOW COOKING TIME
If the cooking time is abnormally slow then the difculty
may be due to insufcient steam pressure. First deter-
mine that pressure on incoming stream line at kettle is
with in 15 PSI of rated kettle pressure. Note that pressure
approaching the rated kettle pressure are liable to set off
the safety relief valve. If required pressure is available
to kettle, then possibly volume of steam is not sufcient.
Minimum 3/4” pipe size is required to the kettle but if the
steam generating source is at a great distance from the
kettle, larger pipe will be required. Finally, the core of the
steam ow will require disassembly and inspection.
PUMPS: PUMP MAKES EXCESSIVE NOISE
1. Check for vacuum leaks in the suction line.
2. Check alignment with drive mechanism. Misalign-
ment will cause wear and subsequent high noise
level in operation.
3. Check compatibility of uid being pumped against
manufacturers recommendations.
4. Relief or unloading valve set to high.
5. Aeration of uid in reservoir, return lines above uid
level.
6. Reversed rotation.
7. Plugged reservoir lter breather.
8. Oil viscosity too high or operating temperature too
low.
9. Loose or worn pump parts.
10. Pump being driven in excess of rated speed.
11. Air leak at pump shaft seal.
12. Oil level too low and drawing air in through inlet pipe
opening.
13. Air bubbles in intake oil.
PUMP PARTS INSIDE HOUSING FAIL TO OPERATE
1. Seizure due to lack of oil.
2. Excessive system pressure above maximum pup rat-
ing.
3. Excessive torquing of housing bolts.
4. Solid matter being drawn in from reservoir and
wedged in pump.
EXCESSIVE PUMP WEAR
5. Abrasive dirt in the hydraulic oil being circulated
through the system.
6. Oil viscosity too low.
7. System pressure exceeds pump rating.
8. Pump misalignment.
9. Air being drawn in through inlet of pump.
DIRTY OIL
1. Components not properly cleaned after servicing.
2. Inadequate screening in ll pipe.
3. Air breather left off.
4. Filter dirty or ruptured.
SOLENOID VALVE: FAILS TO OPERATE
1. Is there an electrical signal to the solenoid or oper-
ating device? Is the voltage too low. Check with the
volmeter, test light in an emergency.
2. Has foreign matter jammed the main spool? Remove
en caps and see that main spool is free in its move-
ment. Remember that there will be a quantity of uid
escaping when the cap is removed and provide a
container to catch it.
3. Are solenoids improperly interlocked so that a sig-
nal is provided to both units simultaneously? Put test
light on each solenoid lead in parallel and watch for
simultaneous lighting. Check electrical interlock. this
condition probably burns out more solenoids then
any other factor.
4. Is uid media excessively hot? Check for localized
heating which may indicate an internal leak, Check
reservoir temperature and see if it is within machine
specications.
5. Voltage too low? If voltage will not complete the stroke
of alternating current (AC) solenoid will burn out coil.
6. Signal to both solenoids of a double solenoid valve si-
multaneously. One or both of the solenoids will be un-
able to complete their stroke and will burn out. Make
certain the electrical signal is interlocked so that this
condition cannot exist.

TROUBLESHOOTING
7. Mechanical damage to leads. Short circuit, open con-
nections, etc.
8. Tight spool or other mechanical parts of the valve be-
ing actuated can prevent the solenoid from complet-
ing its stroke and subsequently burning out.
9. Wrong voltage or frequency will either prevent opera-
tion, because of inadequate capacity to handle the
load with the lower voltage or burn out the oil, be-
cause of improper winding and excessive voltage.
OVERHEATING
1. Continuous operation at relief setting.
a. Stalling under load etc.
b. Fluid viscosity too high or too low.
2. Excessive slippage or internal leakage.
a. Fluid viscosity too low.
3. System relief valve set too high.
4. Power unit ambient temperature too high.
MOISTURE IN OIL
1. Cooling coils not below uid level.
2. Moisture in cans used to replace uid in tanks.
3. Extreme temperature differential in certain geograph-
ical locations.
FOAMING OIL
1. Return of tank line not below uid level.
2. Fluid contaminated with incompatible foreign matter.
3. Suction leak to pump aerating oil.

MAINTENANCE & REPAIR
SUGGESTIONS:
4. Set up a lter maintenance schedule and follow it dili-
gently.
5. Inspect lter elements that have been removed from
the system for signs of failure which may indicate that
the service interval should be shortened and of im-
pending system problems.
6. Do not return to the system any uid which has leaked
out.
7. Always keep the supply of fresh uid covered tightly.
8. Use clean containers, hoses and funnels when lling
the reservoir. Use of a lter cart when adding oil is
highly recommended.
9. Use common sense precautions to prevent entry of
dirt into components that have been temporarily re-
moved from the circuit.
10. Make sure that all clean-out holes, ller caps and
breather cap lters on the reservoir are properly fas-
tened.
11. Do not run the system unless all normally provided
ltration devices are in place.
12. Make certain that the uid used in the system is of a
type recommended by the manufactures of the sys-
tem or components.
13. Before changing from one type of uid to another (pe-
troleum base oil to a re resistant uid) consult com-
ponent and lter manufacturers in selection of uid
and the lters that should be used, Also consult the
publication “Recommended Practice fro the use of
Fire Resistant Fluids for Fluid power Systems” pub-
lished by the National Fluid Power Associatetion.
PREVENTIVE MEASURES:
How to keep your equipment’s hydraulic system from run-
ning too hot.
1. Set up regular schedule for checking the oil tempera-
ture, appearance, smell and feel. Change oil as rec-
ommended by the equipment manufacturer.
2. Be prompt about removing, checking and repairing
or replacing valves, pumps or other components that
are running hot.
3. If relief or ow-control valves are running hot, check
and adjust their settings. Follow your equipment own-
er’s manual.
4. Break in new components gradually. New, close-t-
ting parts expand at different rates and are especially
prone to seize when they get too hot.
5. Start a cold pump or motor on hot oil by jogging
just enough to draw the hot oil into the component.
Then wait a few minutes to allow the temperatures
to equalize in all the pumps parts. Repeat until the
temperature on the outside of the pump ios the same
as that on the piping.
6. Keep your equipment clean. A thick layer of dirt acts
as insulation. It will prevent the hydraulic system from
extracting heat.
7. On hot days and in hot climates check and change
the oil more frequently. Be sure to use an oil recom-
mended for hot weather operation by the equipment
manufacturer or oil supplier.
MAINTAINING PROPER OIL TEMPERATURE:
Hot oil in you equipment’s hydraulic system is out of the
primary causes of poor operation, component failure and
down time. Here are come pointers on maintaining proper
oil temperature.
The oil in you hydraulic system was designed for opera-
tion within a specied temperature range. You may be
able to run it at hotter temperatures for short periods of
time, intermittently, without bad effects. If you run continu-
ously with oil that’s too hot, your equipment will operate
poorly and eventually key components will fail and halt
your unit.
When is hot too hot?
“Hot oil” os a relative term. In most cases, 120OF, at the
reservoir is considered an ideal operating temperature.
Always take an oil temperature reading at the reservoir,
not at a component or any of the piping.
Oil that has been running too hot will look darker and feel
thinner than new oil. It will also smell burnt. Chance are
it will contain more contaminants, because hot oil lead to
accelerated wear of component parts.
Measuring oil temperature
A thermometer is mounted on the reservoir. Make it a
habit to check the thermometer periodically, after the unit
had been running for more then an hour.
