C24EA SERIES ELECTRIC COUNTER CONVECTION STEAMERS
INTRODUCTION
GENERAL
Vulcan convection steamers are produced with
quality workmanship and material. 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 of 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. The C24EA3 is rated 8.5
KW (Basic model), and 9.25 KW (Professional
model). The C24EA5 is rated 15 KW (Basic)
and 15.75 KW (Professional).
Model C24EA3 can accommodate three 2 1/2"
deep (6.4 cm) steam pans. Model C24EA5 can
accommodate five 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.
UNPACKING
This steamer was inspected before leaving the
factory. The transportation company assumes
full responsibility for safe delivery upon
acceptance of the shipment. Immediately after
unpacking, check for possible shipping damage.
If steamer damage is found, save the packaging
material and contact the carrier within 15 days
of delivery.
INSTALLATION CODES AND
STANDARDS
In the United States, the Vulcan steamer must
be installed in accordance with:
1. State and local codes.
2. National Electrical Code (ANSI/NFPA No.70,
latest edition) available from the National
Fire Protection Association, Batterymarch
Park, Quincy, MA 02269.
3. Vapor Removal from Cooking Equipment,
(NFPA-96, latest edition) available from
NFPA.
In Canada, the Vulcan steamer must be installed
in accordance with:
INSTALLATION
Before installing, verify that the electrical supply
agrees with the specifications 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-Hart immediately

C24EA SERIES ELECTRIC COUNTER CONVECTION STEAMERS
LOCATION
Allow space for plumbing and electrical
connections. Minimum clearance is 6" (15.2
cm) on the back for proper air circulation. Allow
adequate access for operating and servicing
the steamer (36" at the front of the steamer, 15"
(38 cm) above the steamer and 18" (45.7 cm)
on right side of steamer).
LEVELING FEET
This steamer is shipped with four 2" leveling
feet. Optional 4" leveling feet are available. The
2" feet can be removed and the optional 4" feet
can be threaded into holes on the bottom of the
unit.
LEVELING
Using a spirit level or pan of water in the bottom
of the steamer, adjust the leveling feet or the
feet on the adjustable legs to level the steamer
side to side with a slight tilt front to back to allow
for proper cavity draining. After the drain is
connected, check for level by pouring water
onto the floor of the compartment. All water
should drain through the opening at the back of
the compartment cavity.
ANCHORING STEAMER
1. Place steamer in the desired location on the
countertop and mark four corners. Remove
the steamer and drill 1/2" holes as indicated in
Figure 1.
2. Apply a bead of RTV or other NSF approved
sealant around the bottom edge of the
steamer. If anchoring the steamer, this
bottom seal is necessary to meet NSF
requirements.
3. Set steamer on countertop and bolt down
securely with 3/8 -16 bolts (not supplied).
Note: Steamer must be installed level side to
side with a slight tilt front to back to allow
for proper draining.

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.
