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.
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.
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
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.

CLEANING
WARNING: DISCONNECT THE
ELECTRICAL POWER TO THE
MACHINE AND FOLLOW LOCKOUT /
TAGOUT PROCEDURES BEFORE
CLEANING.
COOKING COMPARTMENT DRAIN
Keep compartment drain running freely. Inspect
compartment drains daily for blockage. Remove
any particles or debris from the perforated
strainer daily (or more often if needed).
After cooking greasy foods or seafood, close
the doors and operate each compartment for 25
to 30 minutes to flush any residual grease and
oils down the compartment drain. Make a
solution of warm water and non-chloride
detergent and pour 1/2 gallon (1.9 liters) of it
down the compartment drain. Rinse by pouring
1/2 gallon (1.9 liters) of hot water down the
compartment drain.
COMPARTMENT
Wash the inside of the compartment with a
solution of warm water and non-chloride
detergent. Rinse with warm water.
Once a week, thoroughly clean the exposed
surfaces (sides, front, door and top) with a
damp cloth and polish with a clean cloth. To
remove discolorations, use a nonabrasive
cleaner.
DOOR GASKET
Clean the gasket sealing surface of the
compartment door to remove food acids for
maximum gasket life. Do not use any solvents
or sharp instruments. Wash with a cloth
moistened in a solution of mild detergent and
warm water. Rinse with a fresh cloth moistened
with warm water to remove all traces of
detergent.
DRAINING GENERATOR
To prevent malfunction of controls and clogging,
it is essential to drain the generator every day.
This will flush out any accumulated minerals
from the feed water. It will also aid in preventing
internal scale buildup which would interfere with
proper generator operation. Failure to drain the
generator every day will void the steamer
warranty. The presence of minerals in
suspension is indicated by a murky or milky
condition in the first portion of the water drained.
WARNING:
After the generator has been in operation, turn
the unit off with the power switch located on
cooking compartment to drain the generator.
The generator will drain for approximately 15
minutes, removing sediment, scale and lime
buildup in the generator.
THE WATER BEING DRAINED IS
HOT AND UNDER PRESSURE.
USE CARE WHEN CLEANING OR
SERVICING THE GENERATOR.
Wipe dry with a clean cloth. Never apply food
oils or petroleum lubricants directly to the door
gasket. Petroleum-based solvents and
lubricants will reduce gasket life.
LEAVE COMPARTMENT DOOR OPEN
Leave the compartment door slightly open when
the steamer is not in use. When the compartment
is idle, never latch the door and apply pressure
to the door gasket. Leaving the gasket under
pressure can cause permanent deformation
and reduce gasket life.
GUIDELINES FOR MAINTAINING
STAINLESS STEEL SURFACES
There are four things that will break down
stainless steel and allow corrosion to develop:
1) Abrasion
2) Deposits
3) Water
— 13 —
4) Chlorides
C24EA SERIES ELECTRIC COUNTER CONVECTION STEAMERS
Avoid rubbing with steel pads, wire brushes or
scrapers that can leave iron deposits on stainless
steel. Instead, use plastic scouring pads or soft
cloths. For stubborn stains, use products such
as Cameo, Talc or Zud First Impression. Always
rub parallel to the polish lines or with the grain.
Hard water will leave deposits that promote rust
on stainless steel. Treated water from softeners
or certain filters can eliminate these mineral
deposits. Other deposits from food or lubrication
must be properly removed by cleaning. Use
mild detergent and non-chloride cleaners. Rinse
thoroughly. Wipe dry. Where appropriate, apply
a polish recommended for stainless steel (such
as Benefit or Super Sheen) for extra protection
and luster.

COOKING HINTS
The steamer efficiently cooks vegetables and
other foods for immediate serving. Steam cooking
should be carefully time controlled. Keep hot food
holding-time to a minimum to produce the most
appetizing results. Prepare small batches. Cook
only enough to start serving, then cook additional
amounts to meet demand.
PREPARATION
Prepare vegetables, fruits, meats, seafood and
poultry normally by cleaning, separating, cutting,
removing stems, etc. Cook root vegetables in a
perforated pan. Other vegetables may be cooked
in a perforated pan unless juices are being saved.
Liquids can be collected in a solid 12" x 20" pan
placed under a perforated pan.
Perforated pans are used for frankfurters, wieners
and similar items when juices do not need to be
preserved. Solid pans are good for cooking
puddings, rice, and hot breakfast cereals.
Vegetables and fruits are cooked in solid pans in
their own juice. Meats and poultry are cooked in
solid pans to preserve their juice or retain broth.
Canned foods can be heated in their opened
cans (cans placed in 12" x 20" solid pans) or the
contents may be poured into solid pans. DO
NOT place unopened cans in the steamer.
than 15 minutes of cooking time. When a cover
is used, approximately one-third additional
cooking time is necessary.
Cooking time for frozen foods depends on the
amount of defrosting required. If time permits,
allow frozen foods to partially thaw overnight in a
refrigerator. This will reduce their cooking time.
Acceptable Pan Sizes
The steamer accommodates combinations of
full, half and one-third size pans, solid or
perforated.

COOKING GUIDELINES
The steamer cooks vegetables, frankfurters,
eggs in their shells, and certain other meats or
food items at atmospheric pressure.
Frozen Food Items
Separate frozen foods into smaller pieces to
allow more efficient cooking.
Use a pan cover for precooked frozen dishes
that cannot be cooked in the covered containers
in which they are packed if they require more
These cooking guidelines are suggestions only.
You should experiment with your food products
to determine the cooking times that will give you
the best results. Variables which affect cooking
time include size, weight, thickness of foods,
temperature, density, previous condition of the
foods (fresh, pre-blanched or frozen) and degree
of doneness desired.
