WATER QUALITY REQUIREMENT
WARNING
TO PREVENT WATER PIPES FROM
BURSTING, INCOMING WATER
SUPPLY SHOULD BE TURNED OFF
WHEN THE APPLIANCE IS NOT IN USE.
WARNING
WATER SUPPLY MUST BE OPEN WHEN
CLEANING PROGRAM IS ACTIVATED.
VERIFY WATER SUPPLY BEFORE STARTING
CLEANING PROGRAM.
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.

Alto-Shaam now offers an improved water filtration
system for Combitherm®. The CombiGuard™ triple-guard water filtration
system filters dirt, sediment, and other debris as small as 1/2 micron.
This system also significantly reduces chlorine content to protect against
corrosive chorine compounds. CombiGuard improves equipment efficiency,
reduces service requirements and extends the life of the Combi oven. After
installation, confirm that water quality standards specified in this manual
are being met. Filtration systems include one filter cartridge. Additional
cartridges can be purchased separately. Refer to page 7 for additional
ordering information.
The CombiGuard™ BWS Blended Water System utilizes reverse osmosis to
remove more than 97% of the total dissolved solids from water which can be
precisely blended with filtered and treated water.

1Charcoal Filter: The charcoal filter should be
inspected for contaminant's on a regular basis.
Replacement must be made at a minimum of
three month intervals — more often if heavy
contaminant's are visible or if the filter no
longer controls odors.
To remove the charcoal filter, pull and slide out.
When replacing the filter, ensure that the filter
clip is in place at rear of the filter. Make certain
the air flow arrow(s) point toward the hood fan
(back of unit), and that the filter is replaced
using the filter track in the metal back plate
provided with the hood.

2Grease Filter: Cleaning frequency should be
based on oven usage with a maximum of two
weeks between cleaning if the oven is used for
non-grease laden products or steam applications
only. Grease laden products require cleaning
frequency of at least once a week.
Remove the grease filter by pulling it straight
out of the housing. Place the filter in the
dishwasher or wash separately by placing in
hot, soapy water until all grease and particles
have been removed. Rinse thoroughly. Allow
the filter to air dry before reinstalling.
To replace the grease filter, the metal handles
on the filter casing should be facing toward the
front of the unit.
