C24EA SERIES ELECTRIC COUNTER CONVECTION STEAMERS
PLUMBING CONNECTIONS
WARNING: PLUMBING  CONNECTIONS  MUST
COMPLY  WITH  APPLICABLE
SANITARY,  SAFETY  AND
PLUMBING  CODES.
Water Requirements
Proper water quality can improve the taste of
the food prepared in the steamer, reduce liming
in the steam generator and extend equipment
life. Water conditions vary from one location to
another. Ask your municipal water supplier for
details about your local water supply prior to
installation. Presence of sediment, silica, excess
chlorides or other dissolved solids may lead to
a recommendation for alternate form(s) of water
treatment. Test the water with the test strip
included with the steamer. Other factors
affecting steam generation are iron content,
amount of chloridation and dissolved gases.
Water Treatment
A local water treatment specialist should be
consulted before installation of steam generating
equipment.
Supply  Pressure
20 - 60 psig
Hardness*
No  more than 3 grains
Silica
less than 13 ppm
Total  Chlorine
less than 4.0 ppm
PH  range
6.5 - 8
Undissolved Solids less than 5 microns
*17.1 ppm = 1 grain of hardness
If the water supply fails to meet these standards,
it will be necessary to install a water conditioner
on the generator water feed. The use of strainers
or filters will not remove minerals from the
water.
Water Supply Connection
Connect the treated cold water supply line to the
3/4" (19 mm) (male hose thread) inlet. Connect
the untreated cold water supply line to the 3/4"
(19 mm) (male hose thread) inlet marked
UNTREATED WATER.
A water filter system is recommended for the
water supply line going to the treated water inlet.
Follow the recommendations for use and
installation instructions shipped with the water
filter. If a water filter is not installed, the steam
generator warranty may be limited.
A manual shutoff valve must be provided in a
convenient location near the steamer.
DRAIN CONNECTIONS
The drain connection (Figure 2) must be 1 1/2"
(38 mm) down, preferably with one elbow only,
maximum length of 6' and piped to an open gap
type drain.
CAUTION: In  order to avoid any back
pressure in the steamer, do
not make a solid connection to
any drain. FAILURE TO DO SO
CAN DAMAGE THE STEAMER
AND VOIDS THE WARRANTY.
A vent must be installed to avoid creating a
vacuum or pressure in the cooking chamber.
