Water Quality Requirements
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 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
heat producing equipment.
WARNING
Significant damage to the appliance 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 STANDARDS
TWO (2) COLD WATER INLETS - DRINKING QUALITY*
ONE (1) TREATED WATER INLET: 3/4" NPT connection. Line pressure 30 psi minimum dynamic and
90 psi maximum static (200 to 600 kPa) at a minimum flow rate of 0.13 gpm (0.5 L/min).
ONE (1) UNTREATED WATER INLET: 3/4" NPT connection. Line pressure 30 psi minimum dynamic and
90 psi maximum static (200 to 600 kPa) at a minimum flow rate of 2.64 gpm (10 L/min).
* Both inlets can be from same source. Divide using a manifold. Run one side through treatment device before running to oven.
Must meet line pressure and flow rate specifications for both inlets.
WATER DRAIN: 1-1/2" NPT (50mm) connection with a vertical vent to extend above the exhaust vent.
Materials must withstand temperatures up to 200°F (93°C).
It is the sole responsibility of the owner/operator/purchaser of this equipment

NOTICE:
To prevent water pipes from bursting, the
water supply shutoff valve should be set to the
OFF position when the oven is not in use.
NOTICE:
Make sure that the water supply shutoff valve
is in the ON position before using the oven and
before running a cleaning cycle.
NOTICE:
Both treated and untreated water connections
must be connected for proper operation of the
oven. All connections can be treated water, but
should never be connected to only untreated
water. Unions or flexible lines should be used
to allow for oven movement when being
serviced or cleaning is needed.
