NOTICE
Significant damage to the oven cavity, elements, or
heat exchanger could result from improper water
quality. Failure to meet the water quality requirements
and observe this precaution will void the warranty.
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.

To prevent water pipes from bursting,
incoming water supply should be
turned off when the appliance is not
in use.

A water filtration system, when properly installed,
maintained, and combined with the required levels of
steam producing 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.
It is the sole responsibility of the owner/operator/
purchaser of this equipment to verify that the incoming
water supply is comprehensively tested and if required,
a means of "water treatment" provided that would meet
compliance requirements with the published water quality
standards published at right. Non-compliance with these
minimum standards will potentially damage this equipment
and/or components and VOID the original equipment
manufacturer's warranty. Alto-Shaam recommends using
OptiPure® [www.optipurewater.com] products to properly
treat your water.
Alto-Shaam will continue our efforts to provide viable
solutions to ease the impact of water quality as it relates to
steam generating equipment.
