5.0 MAINTENANCE
Daily
1. Ensure there is adequate vacuum in the kettle jacket before operating.
2. Ensure that the appliance and controls are not damaged and that it can be safely
operated.
3. Ensure the work area of the operator is not slippery and is clear of debris so as to
provide a safe workplace.
4. Ensure the appliance is clean before each use.
5. Check that the LOW WATER control is operational. Tilting the kettle more than 5 or 10
degrees should cause the LOW WATER signal light to come on.
Every Two Weeks
1. Perform a “try lever test” on the safety relief valve.
WARNING: The safety relief valve may discharge large amounts of
steam and/or hot water. Keep away from the discharge tube at all
times. Warn others in the area so they will not be startled by the
sound.
Under normal operating conditions a “try lever test” must be performed every two months.
Under severe service conditions, or if corrosion and/or deposits are noticed within the valve
body, testing must be performed more often. A “try lever test” must also be performed at
the end of any non-service period.
Test at or near maximum operating pressure by holding the test lever fully open for at least
5 seconds to flush the valve seat free of sediment and debris. Then release lever and
permit the valve to snap shut.
If lift lever does not activate, or there is no evidence of discharge, discontinue use of
equipment immediately and contact a licensed contractor or qualified service personnel.
Every Six Months
1.
Lubricate the bronze trunnion bearings.
2.
Check the worm gearbox for evidence of oil leaks. It is permanently lubricated with
synthetic oil (Shell TIVELA OIL SC320 or equivalent) and should not require
maintenance.
3.
Check that the tilt mechanism has not become loose or has excessive backlash.
