INSTALLATION, OPERATION AND CARE OF

MODEL C24EA SERIES STEAMERS

PLEASE KEEP THIS MANUAL FOR FUTURE USE

GENERAL

Vulcan convection steamers are produced with

quality workmanship and materials. Proper

installation, usage and maintenance will result

in many years of satisfactory performance. It is

suggested that you thoroughly read this entire

manual and carefully follow all the instructions

provided.

The C24EA3 and C24EA5 convection steamers

are single compartment, electric, pressureless

steam cookers with an internal electric steam

generator that maintains water temperature at

approximately 195°F.

Model C24EA3 can accommodate three 2 1/2"

deep (6.4 cm) steam pans. Model C24EA5

can accommodate ﬁ ve 2 1/2"deep (6.4 cm)

steam pans. The C24EA3 and C24EA5 electric

convection steamers are designed for cooking

vegetables, eggs, and other foods, in commercial

kitchens. The steamer has a 0 to 60-minute

timer. The steamers are designed for countertop

installation or on optional stands available from

your Vulcan dealer.

PROFESSIONAL POWERSTEAM

OPTION

Vulcan’s patented super-heated steam option

cooks at 235°F compared to conventional

atmospheric steamers at 212°F.

ENERGY STAR STEAMER OPTION

Smart Steam Sensors continuously measure

and regulate steam temperature and production,

reducing scale buildup, ﬁ lter changes and excess

steam/water (up to 90%). Utility rebate qualiﬁ ed

where oﬀ ered.

SONICSAFE SCALE PREVENTION

OPTION

Sound waves create millions of microscopic

bubbles inside the steam generator, causing

powerful vacuum energy that prevents scale from

attaching to the walls of the steamer. The control

panel is equipped with indicator lights showing

that the SonicSafe system is in operation and

to indicate if there is a problem and service is

needed.

De-lime once a quarter instead of monthly, and

change your carbon ﬁ lter just once a year.

INSTALLATION

Before installing, verify that the electrical supply

agrees with the speciﬁ cations on the data plate

located on the back panel. If the supply and

equipment requirements do not agree, do not

proceed with the installation. Contact your dealer

or Vulcan immediately

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 20 psig ﬂ owing -

60 psig static

Hardness No more than 3 grains

Silica less than 13 ppm

Total Chlorine less than 0.5 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

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.

C24EA SERIES ELECTRIC COUNTER CONVECTION STEAMERS

Figure 2

VENT HOOD

Local codes may require the steamer to be

located under an exhaust hood. Information on

the construction and installation of ventilating

hoods may be obtained from Vapor Removal

from Cooking Equipment, NFPA standard No.

96 (latest edition).

Temperatures in the drain can brieﬂ y reach as

high as 212°F (100°C). Local codes may require

that the temperature of drain water be no greater

than 140°F (60°C). Some provision for lowering

the water temperature must be provided by the

user or installer to meet this code requirement.

C24EA SERIES ELECTRIC COUNTER CONVECTION STEAMERS

CLEANING

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 ﬂ ush 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.

DRAINING GENERATOR

To prevent malfunction of controls and clogging,

it is essential to drain the generator every day.

This will ﬂ ush 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 ﬁ rst portion of the water drained.

The water being drained is

hot and under pressure. Use care when

cleaning or servicing the generator.

After the generator has been in operation, turn

the unit oﬀ with the pow er 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.

COMPARTMENT

Wash the inside of the compartment with

a solution of warm water and non-chloride

detergent. Rinse with warm water.

Thoroughly clean the exposed surfaces (sides,

front, door and top) with a damp cloth and polish

with a clean cloth daily. 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.

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.

C24EA SERIES ELECTRIC COUNTER CONVECTION STEAMERS

Contrary to popular belief, stainless steels ARE suscep-

tible to rusting.

Corrosion on metals is everywhere. It is recognized quickly on

iron and steel as unsightly yellow/orange rust. Such metals

are called “active” because they actively corrode in a natural

environment when their atoms combine with oxygen to form rust.

Stainless steels are passive metals because they contain other

metals, like chromium, nickel and manganese that stabilize the

atoms. 400 series stainless steels are called ferritic, contain

chromium, and are magnetic; 300 series stainless steels are

called austenitic, contain chromium and nickel; and 200 series

stainless, also austenitic, contains manganese, nitrogen and

carbon. Austenitic types of stainless are not magnetic, and

generally provide greater resistance to corrosion than ferritic

types.

With 12-30 percent chromium, an invisible passive ﬁ lm covers

the steel’s surface acting as a shield against corrosion. As long

as the ﬁ lm is intact and not broken or contaminated, the metal is

passive and stain-less. If the passive ﬁ lm of stainless steel has

been broken, equipment starts to corrode. At its end, it rusts.

Enemies of Stainless Steel

There are three basic things which can break down stainless

steel’s passivity layer and allow corrosion to occur.

1. Mechanical abrasion

2. Deposits and water

3. Chlorides

Mechanical abrasion means those things that will scratch a

steel surface. Steel pads, wire brushes and scrapers are prime

examples.

Water comes out of the faucet in varying degrees of hardness.

Depending on what part of the country you live in, you may

have hard or soft water. Hard water may leave spots, and when

heated leave deposits behind that if left to sit, will break down

the passive layer and rust stainless steel. Other deposits from

food preparation and service must be properly removed.

Chlorides are found nearly everywhere. They are in water, food

and table salt. One of the worst chloride perpetrators can come

from household and industrial cleaners.

So what does all this mean? Don’t Despair!

Here are a few steps that can help prevent stainless steel rust.

1. Use the proper tools.

When cleaning stainless steel products, use non-abrasive

tools. Soft cloths and plastic scouring pads will not harm

steel’s passive layer. Stainless steel pads also can be used

but the scrubbing motion must be in the direction of the

manufacturers’ polishing marks.

2. Clean with the polish lines.

Some stainless steel comes with visible polishing lines or

“grain.” When visible lines are present, always scrub in a

motion parallel to the lines. When the grain cannot be seen,

play it safe and use a soft cloth or plastic scouring pad.

3. Use alkaline, alkaline chlorinated or non-chloride

containing cleaners.

While many traditional cleaners are loaded with chlorides,

the industry is providing an ever-increasing choice of non-

chloride cleaners. If you are not sure of chloride content

in the cleaner used, contact your cleaner supplier. If your

present cleaner contains chlorides, ask your supplier if they

have an alternative. Avoid cleaners containing quaternary

salts; it also can attack stainless steel and cause pitting and

rusting.

4. Treat your water.

Though this is not always practical, softening hard water

can do much to reduce deposits. There are certain ﬁ lters

that can be installed to remove distasteful and corrosive

elements. To insure proper water treatment, call a treatment

specialist.

5. Keep your food equipment clean.

Use alkaline, alkaline chlorinated or non-chloride cleaners

at recommended strength. Clean frequently to avoid build-

up of hard, stubborn stains. If you boil water in stainless

steel equipment, remember the single most likely cause

of damage is chlorides in the water. Heating cleaners that

contain chlorides have a similar eﬀ ect.

6. Rinse, rinse, rinse.

If chlorinated cleaners are used, rinse and wipe equipment

and supplies dry immediately. The sooner you wipe oﬀ

standing water, especially when it contains cleaning agents,

the better. After wiping equipment down, allow it to air dry;

oxygen helps maintain the stainless steel’s passivity ﬁ lm.

7. Never use hydrochloric acid (muriatic acid) on

stainless steel.

8. Regularly restore/passivate stainless steel.

Review

1. Stainless steels rust when passivity (ﬁ lm-shield) breaks

down as a result of scrapes, scratches, deposits and

chlorides.

2. Stainless steel rust starts with pits and cracks.

3. Use the proper tools. Do not use steel pads, wire brushes

or scrapers to clean stainless steel.

4. Use non-chlorinated cleaners at recommended

concentrations. Use only chloride free cleaners.

5. Soften your water. Use ﬁ lters and softeners whenever

possible.

6. Wipe oﬀ cleaning agent(s) and standing water as soon as

possible. Prolonged contact causes eventual problems.

To learn more about chloride-stress corrosion and how to

prevent it, contact the equipment manufacturer or cleaning

materials supplier.

COOKING HINTS

The steamer eﬃ ciently 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.

Frozen Food Items

Separate frozen foods into smaller pieces to

allow more eﬃ cient 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

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.

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 aﬀ ect 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.

Cook times will vary and are aﬀ ected by.

1. Starting temperature of frozen, refrigerated,

and fresh foods.

2. Your location's altitude.

3. Type and size of pan used.

4. Covered or uncovered.

Caution: Pans covered with lids, foil, or

plastic wrap will hold hot condensate

water that can spill during unloading.

Notice: Loose foil and plastic wrap left

in the cooking cavity will block the drain

screen. This will cause the cavity to

pressurize and the door seal to leak.
