Glass Replacement and Adjustment Instructions
In order to replace or adjust the glass, the glass must be
placed in the raised position. The underside of the clamp is
exposed, revealing the tightening screws. By turning these
screws counterclockwise 1/4 turn each, the glass will be
loosened for either removal or adjustment.
Note: Do not overtighten the screws since damage may occur.
Stainless Steel Cleaning and Care
There are three basic things, which can break down your
stainless steel’s passivity layer and allow corrosion.
1. Mechanical Abrasion
Mechanical Abrasion means those things that
will scratch the steels surface. Steel Pads, wire
Brushes, and Scrapers are prime examples.
2. Water
Water comes out of our tap in varying degrees of
hardness. Depending on what part of the country
you live in, you may have hard or soft water. Hard
water may leave spots. Also, when heated, hard
water leaves deposits behind that if left to sit, will
break down the passive layer and rust your stainless
steel. Other deposits from food preparation and
service must be properly removed.
3. Chlorides
Chlorides are found nearly everywhere. They
are in water, food and table salt. One of the worst
perpetrators of chlorides can come from household
and industrial cleaners.
Don’t Despair! Here are a few steps that can help prevent
stainless steel rust.
1. Use the Proper Tools
CLEANING PRECAUTIONS
When cleaning:

Do not use high pressure water hoses

Do not introduce water faster then waste outlet can drain

NEVER INTRODUCE WATER ON SELF CONTAINED UNIT
WITH AN EVPORATOR PAN

NEVER USE A CLEANING OR SANITIZING SOLUTION
THAT HAS AN OIL BASE (these will dissolve the butyl
sealants) or an AMMONA BASE (this will corrode the
copper components of the case)

TO PRESERVE THE ATTRACTIVE FINISH:

DO USE WATER AND A MILD DETERGENT FOR THE
EXTERIOR ONLY

DO NOT USE A CHLORINATED CLEANER ON ANY
SURFACE

DO NOT USE ABRASIVES OR STEEL WOOL SCOURING
PADS (these will mar the finish)
