7. IMPORTANT CAUTIONS
The following important cautions describe ways to avoid incorrect operating
procedures which will cause serious damage to the FREEZER.
7.1 PROTECT CHROME CYLINDER
The inside surface of the freezing cylinder is chrome plated. Incorrect
operating procedures may cause severe damage or rapid wear of the chrome
surface and require an expensive cylinder replacement.
♦ Do not operate dasher without product or water in the cylinder.
♦ Do not operate dasher with worn scraper blades at less than the recommended
width dimension.
♦ Do not use any type of acid cleaner or acid rinse. Acid attacks chrome.
7.2. AVOID FREEZE-UP
Incorrect operating procedures may cause a "freeze-up". A freeze-up occurs when the
product becomes too cold and too stiff. The resulting load on the dasher motor and
drive components may cause severe damage to the dasher, belts, motor, and other
drive components. If the dasher stops, the product inside the cylinder will freeze
further, requiring a time consuming defrosting procedure before production can
resume.
In addition to the operation instructions to prevent freeze up:
♦ Do not turn on the refrigeration without the dasher running.
♦ Do not allow the supply of mix to the freezer to stop during freezing operations.
♦ Do not operate with product stiffness at greater than 100% motor load.
♦ Do not turn on the refrigeration when flushing out with water.
♦ Do not leave the refrigeration on when flushing out with water.
♦ Do not obstruct the freezer outlet.
7.3. BEWARE OF SANITIZING SOLUTIONS
WARNING !
Sanitizing solutions are extremely corrosive, especially those which contain
halogen compounds (chlorine, bromine, iodine). Solutions of these chemicals, will
attack the chrome surface of the freezing cylinder and the special hard alloy
stainless steel scraper blades.
To prevent serious damage:
• Do not sanitize the freezer sooner than 15 minutes immediately prior to starting
production.
• Do not leave sanitizing solutions in prolonged contact with any surface - product
contact or exterior. As droplets dry out they become more concentrated and will
cause corrosion pitting.
