KETTLE JACKET CLEANOUT AND PASSIVATION PROCEDURES
The following procedure should be preformed at least once every three years to prevent possible corrosion and ensure the optimum life of the kettle.
WARNING:
IMPROPER REFILLING OF KETTLE JACKET WILL RESULT IN IRREVERSIBLE DAMAGE TO UNIT.
DANGER:
WORKING ON MACHINES WITH POWER COULD RESULT IN SEVERE ELECTRICAL SHOCK.
DANGER:
MOLYFILM 315 IS CORROSIVE, AVOID
CONTACT WITH SKIN AND EYES.
DANGER:
EXTREMELY HOT SURFACES. WORK ONLY ON COLD KETTLE.
DANGER:
AVOID INHALATION - VAPORS FROM
MOLYFILM 315 MAY BE HARMFUL OR FATAL.
DESCRIPTION - Molyfilm 315 inhibits corrosion in stainless steel and copper. A pH buffer is present to assist in maintaining the appropriate pH to assist in corrosion inhibition.
DISPOSAL - Follow all Federal, State and local codes when disposing of product.
SHELF LIFE - Molyfilm 315’s effectiveness will diminish after three years.
