WATER SUPPLY

CONNECT TO POTABLE (DRINKABLE) COLD WATER ONLY

WATER PRESSURE REQUIREMENTS: MINIMUM 30 PSI (2 BAR)

MAXIMUM 90 PSI (6 BAR)

Flush the water line at the installation site before connecting the oven to the water supply. A shut-off valve and

approved back-flow preventer must be installed when connecting the oven to the cold water intake. The water

supply line must be a minimum of 3/4-inch (NPT) (19mm). A hose connector is supplied for flexible hose

connection to the COLD water source. Connected water should test at hardness level of 5 to 9 grains per gallon

(85 to 154 ppm). A water filtration system is recommended if the water supply is between 5 and 9 gpg of

hardness. If water tests over 18 gpg of hardness (344 ppm), the

installation of a water softener to maintain oven function is strongly

recommended.

PIPE SEALING TAPE (TEFLON®) MUST BE USED

AT ALL CONNECTION POINTS.

The use of a pipe sealing compound is not recommended.

THE SHUT-OFF VALVE MUST BE IN THE OPEN POSITION

WHEN THE OVEN IS BEING USED.

The hand shower spray hose is installed adjacent

to the cold water intake connection. A ball valve

is installed on the oven for hose connection to the

COLD water source. Assemble the washer and

the flexible hose on the ball valve and hang the

spray handle on the holder previously installed

on the oven.

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 chlorine compounds. CombiGuard

improves equipment efficiency, reduces service requirements and

extends the life of the Combitherm. Filtration system includes one

filter cartridge. Additional cartridges (FI-26356) can be

purchased separately.
