COMBITHERM GAS INSTALLATION AND MAINTENANCE MANUAL — 6470ML
PG. 6
1.10 WATER SUPPLY
CONNECT TO POTABLE (DRINKABLE) COLD WATER ONLY
COMBITHERM® GAS INSTALLATION
WATER PRESSURE REQUIREMENTS:
MINIMUM 40 PSI (2.8 BAR)
MAXIMUM 90 PSI (6.2 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.
THE MAIN WATER SUPPLY SHUT-OFF VALVE MUST BE IN
THE OPEN POSITION WHEN THE OVEN IS BEING USED.
PIPE SEALING TAPE (TEFLON®) MUST
BE USED AT ALL CONNECTION POINTS.
The use of a pipe sealing compound is not recommended.
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.
The oven must discharge through an indirect waste
pipe by means of an air gap. The drain thread is
1-1/2-inch (38,1mm) NPT. A union is required.
Install a 1-1/2-inch (38,1mm) diameter drain line.
The drain line must always be a positive gradient
away from the oven and not more than 12-inches
(305mm) before an air gap.
NOTE: In the U.S.A., this equipment is to be
installed to comply with the Basic Plumbing
Code of the Building Officials and Code
Administrators International, Inc. [BOCA],
and the Food Service Sanitation Manual of
the Food & Drug Administration [FDA].
If several units are to be connected to one drain pipe,
the dimensions of the pipe must be sufficient to allow
an unobstructed water drain system.
