 NEVER USE AN ACID 

BASED CLEANING SOLUTION!  MANY 

FOOD PRODUCTS HAVE AN ACIDIC 

CONTENT WHICH CAN DETERIORATE THE 

FINISH.  BE SURE TO CLEAN ALL FOOD 

PRODUCTS FROM ANY STAINLESS STEEL 

SURFACE.  COMMON ITEMS INCLUDE, 

TOMATOES, PEPPERS AND OTHER 

VEGETABLES.

 THE POWER MUST BE 

TURNED OFF AND DISCONNECTED 

AT ALL TIMES WHEN PERFORMING 

MAINTENANCE OR REPAIR FUNCTIONS.

CAUTION

 NEVER USE A HIGH-

PRESSURE WATER WASH FOR THIS 

CLEANING PROCEDURE AS WATER CAN 

DAMAGE ELECTRICAL COMPONENTS

CAUTION

 ELECTRICAL SHOCK HAZARD.  

DO NOT WASH WITH WATER JET OR 

HOSE.
DANGER GLASS: INSPECT GLASS DAILY 

FOR CHIPS, CRACKS, OR BREAKING. 

DISCARD ALL FOOD AND NOTIFY 

MANAGER IF ANY CHIPS, CRACKS, OR 

BROKEN GLASS ARE FOUND. DO NOT 

USE EQUIPMENT. ALL GLASS MUST BE 

IN GOOD CONDITION BEFORE USING 

EQUIPMENT TO HOLD FOOD.

RECOMMENDED SUPPLIES

Cleaning Towels
Non-Scratch Scrub Pad
SYR Cleaning Brush Tool
KAY™ Degreaser
KAY® SINK SANITIZER, KAYQUAT™ Sanitizer, or 

compatible sanitizer

PROCEDURE 

1.  Turn switch to standby mode, unplug, and allow 

to cool for 30 minutes.

2.  Remove all holding pans and heat sink covers.  

Wash, rinse, and sanitize at the 3-compartment 

sink.   

3.  Allow to air dry.

4.  Spray a cleaning towel, or non-scratch scrub pad 

when necessary, with soapy solution or KAY™ 

Degreaser. Fully clean upper glass surfaces by 

hand, as well as lower heat sink surfaces.

NOTE: Never spray cleaning solution directly 

onto the cabinet.

5.   If daily cleaning is performed routinely, deeper, 

more aggressive, cleaning methods can be 

avoided.  Over longer periods of time, fried food 

product can accumulate and bake on to the upper 

glass surfaces of the compartments.  The SYR 

Cleaning Brush Tool can be used to remove 

heavier accumulation.

6.  Spray the brush head with KAY™ Degreaser 

and use the SYR Cleaning Brush Tool, as shown 

below, by gently sliding in and out of each 

compartment.

7.  Use a sanitizer-soaked towel and wipe out all 

compartments on the holding unit.  Wipe top 

compartments first, and then lower compartments.

IMPORTANT: Use clean, sanitizer-soaked 

towels (Important: towels must be wrung out so 

that they are damp and not dripping, dripping 

towels may harm the unit.) 

DAILY INSPECTION CHECKLIST: 

•  Inspect glass for chips, cracks, or breaking. 

•  Make sure that: 

•  Unit is free of any visible food soils. 

•  Unit is free of grease or soils in holding 

compartment. 

• 

Exterior of unit is free of smudges or soil. 

•  Holding pans are free of any food soil residue.

•  Pans are free of damage such as cracks.
