Cleaning Instructions

WARNING

TYLER Refrigeration does not recommend the use of high pressure cleaning equipment on
display cases!!  High pressure cleaners can penetrate and/or damage joint seals.  Damaged
seals allow water leaks and/or air leaks that can cause poor case refrigeration.

CAUTION

• When cleaning this case, try not to introduce water into the case faster  than it can be

carried away by the waste outlet.

• Liquid chlorine bleach is corrosive to metals.  The use of bleach or products containing

bleach will damage metal surfaces and void the case warranty.

• Sanitize the case with Quaternary Ammonium Solutions (ex: KAYQUAT II, 

J-512 Sanitizer, SANIQUAT 512, etc...) approved per 21CFR 178.1010, followed by ade-
quate draining and air drying.  These solutions may be obtained from Kay Chemical Co.,
Johnson Wax Professional, Coastwide Laboratories, etc....

• Always use a soft cloth or sponge with mild detergent and water to clean any glass.

Never use abrasives or scouring pads to clean glass.  They can scratch and/or damage
the glass.

See “General (UL/NSF) I&S Manual” for case cleaning instructions.
