Maintenance
NOTICE: Contact an authorized representative when repairs are required.
A.
Periodic Maintenance
A Service Log is provided at the back of this manual with the warranty
information. Each time maintenance is performed on your kettle, enter the
date on which the work was done, what was done, and who did it. Keep this
manual on file and available for operators to use.
Periodic inspection will minimize equipment down time and increase the
efficiency of operation. The following points should be checked:
[BY OPERATOR]
1.
Check the pressure/vacuum gauge every day. The gauge should show
a vacuum of 20 to 30 inches, when the kettle is cold. If it does not, see
"Jacket Vacuum" on page 14.
2.
Also check the jacket water level every day. It should be between the
marks on the gauge glass. If the level is low, see "Jacket Filling and Water
Treatment" on page 14.
3.
Carefully test the pressure relief valve at least twice each month. With
the kettle operating at 15 psi (105 kPa),pull the test lever and let it snap
back to its closed position. If there is little discharge (mostly air), and the
pressure gauge drops back to zero PSI, allow the pressure to build back
to five PSI and repeat the procedure. (Tip: Using a screwdriver or other
implement to pull the ring will help you avoid contact with the steam.

4.
Electrical wiring should be kept securely connected and in good condition.
5.
The inside of the support housing should be kept clean.
