USE A DRINKING QUALITY, COLD WATER SUPPLY ONLY
Water quality is of critical importance when
installing steam producing equipment of any kind,
particulary
high temperature
steam producing
equipment. Water that is perfectly safe to drink is
composed of chemical characteristics that directly
affect the metal surfaces of steam producing
equipment. These chemical characteristics differ
greatly from region to region throughout the U.S.
and the world.
Varying combinations of pH;
alkalinity; hardness; chlorides; total dissolved
solids; and other chemical characteristics, when
subjected to high temperatures, will cause water to
have a tendency to either scale or corrode.
Alto-Shaam has consulted with people who
understand the properties of water in order to
provide water quality standards that meet the
broadest possible range of acceptable water quality
requirements to help protect your investment.
We strongly urge water testing to ascertain the
water quality on site prior to the installation of any
steam producing equipment. Since water quality is
an important issue, Alto-Shaam is committed to
provide as much information as possible to help
protect the investment made in this equipment.
A CombiGuard
™
Water Filtration System can be
purchased as an option for installation on the
Combitherm oven. This filter, when properly
installed, maintained, and combined with the
required levels of steam generating equipment
maintenance, will help lessen the affect water has on
metal surfaces. It will not, however, provide
complete protection against all water damage from
region to region.
Due to the complexity of water chemistry, it is
important to understand that water quality plays a
significant role in the longevity of steam producing
equipment. Water quality and required
maintenance of steam generating equipment is the
direct responsibility of the owner/operator.
Damage incurred as a direct result of poor water
quality and/or surfaces affected by water quality is
also the responsibility of the owner/operator.
Damage due to water quality that does not meet the
minimum standards shown below is not covered
under the Alto-Shaam Combitherm warranty.
Alto-Shaam will continue our efforts to provide
viable solutions to ease the impact of water quality
as it relates to steam generating equipment.
