SERVICE CONNECTIONS

Water Connections

No water supply connections are required, as
the steamer is filled manually.

Water Treatment

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.

Drain Connection

The C24EO can be configured to drain through
either the rear panel or through the bottom
base plate.

The unit is configured to be drained through
the rear panel from the factory. The unit is
supplied with a 12" length of

5

/8" ID hose. If this
length is insufficient, remove the hose and
install a new hose ordered to the desired
length. The factory

5

/8" ID silicone hose part

number is 557475. Hose is sold by the foot.

A local water treatment specialist should be
consulted before installation of steam
generating equipment.

Hardness* No more than 3 grains

Silica less than 13 ppm

Total Chlorine less than 4.0 ppm

PH range 6.5 to 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. The use of strainers or
filters will not remove minerals from the water.

Water Requirements

Proper water quality can improve the taste of
the food prepared in the steamer, reduce
liming in the steam generator and extend

See Figure 3.

Figure 3: Rear Panel Drain Connection

(Viewed with right side panel removed)

To field configure the drain through the bottom
base plate, the 4" leg kit (part number 843889)
is required. Also required are a

1

/2" NPT close
pipe nipple (11/8" long) and a 1/2" NPT 90°
elbow, which are available through local home
improvement or plumbing supply houses.

1. Remove right side panel.

2. Remove hose barb from drain.

3. Remove knockout from base plate.
