use a drinking quality, cold water supply only
water quality is of critical importance when
installing steam producing equipment of any kind,
particularly 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.
