water quality requirement

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.
