CASE CLEANING
Case is designed to facilitate cleaning. There is a wide
radius formed on the front and back of the inside bottom of
the tank (ORB & ORBH) that helps accelerate liquid flow
and eliminates difficult-to-clean sharp corners. All surfaces
pitch to a deep-drawn drain trough that angles toward the
front and center of case where the waste outlet is located
for easy access.
The coil is covered to keep food fluids from entering,
but the cover lifts up easily when coil cleaning is desired.
The single piece fan plenum lifts up for cleaning, exposing a
major portion of the inside bottom of the tank. Make certain
fan plenum is properly closed after cleaning to avoid air
leaks.
CLEANING PROCEDURES
• A periodic cleaning schedule should be established to maintain proper sanitation, insure maximum operating efficiency, and
avoid the corrosive action of food fluids on metal parts that are left on for long periods of time. We recommend cleaning once
a week.
• To avoid shock hazard, be sure all electrical power is turned off before cleaning. In some installations, more than one
disconnect switch may have to be turned off to completely de-energize the case.
• Check waste outlet to insure it is not clogged before starting the cleaning process and avoid introducing water faster than the
case drain can carry it away.
• Avoid spraying cleaning solutions directly on fans or electrical connections.
• Provide a temporary separator between those cases which are being cleaned and those which are not.
• Allow cases to be turned off long enough to clean any frost or ice from coil and flue areas.
• Remove and clean discharge honeycomb. You may need to use spray detergent and a soft, long bristle brush.
• Use mild detergent and warm water. When necessary, water and baking soda solution will help remove case odors. Avoid
abrasive scouring powders or pads.
• Remove front panels and clean underneath the case with a broom and a long handled mop. Instructions for removing the
front panels can be found on page 13 of this manual.
• Use warm water and a disinfecting cleaning solution when cleaning underneath the cases.
• When cleaning antifog doors please refer to Appendix A, on page 37, for more details.
