Vulcan-Hart GT150E ML-52640, GL80E ML-52637 Maintenance, Pressure Relief Valve, Low Water Cut-Off

MAINTENANCE

WARNING: THE KETTLE AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING AND SERVICING THE KETTLE.

WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AND FOLLOW LOCKOUT / TAGOUT PROCEDURE.

PRESSURE RELIEF VALVE

Open the pressure relief valve at least once a day to avoid lime build-up. If leakage occurs or if the valve opens below the rated psi, it will need to be replaced by your Vulcan authorized servicer.

LOW WATER CUT-OFF

This device should be removed and inspected for lime build-up at least once a year. The float must move freely in its cage. Clean if necessary. Replace if lime or sludge cannot be removed to allow the float to move freely. Contact your local Vulcan authorized servicer.

JACKET WATER & JACKET WATER TREATMENT

The kettle jacket is filled at the factory with chemically pure water mixed with a boiler treatment corrosion inhibitor. During normal kettle operation, it should not be necessary to frequently add water to the kettle jacket. If the water level in the sight glass falls below half, add distilled or chemically pure water to the jacket through the fill tube. The water level in the sight glass should be maintained to just above the halfway position in the sight glass.

If the water in the sight glass appears dirty, it is necessary to have a qualified service technician remove the fluid in the kettle, perform a delime or cleaning operation and refill the kettle with distilled, chemically pure water with a boiler treatment additive.

Do not fill kettle jacket with chlorinated tap water. Appliance failure caused by water quality is not covered under warranty.

HOOD VENTILATION SYSTEM

Annually, when cool, check the ventilation system and clear any obstructions.
