C24EA SERIES ELECTRIC COUNTER CONVECTION STEAMERS

PLUMBING CONNECTIONS

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
aff ecting 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
Hardness
Silica
Total Chlorine
PH range
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
or scale & chlorine reduction fi lter system on
the generator water feed. The use of strainers
or particle fi lters 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.
Do not over tighten water
connections. Over tightening the hose
connections will damage the water valve.
Turn hose connection by hand till snug
and then tighten with pliers 2/3 of a turn.
Check for leaks.
If water lines move during water
fi ll valve operation then a water hammer
arrestors must be added.
A water fi lter 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
fi lter. If a water fi lter 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.
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.
If two steamers are stacked they must have
independent drains and vents.
