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.

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

This unit is shipped pre wired for 208/60/3. 240v & single phase operation require changes to the heater connection 240/60/3, 240/60/1 and 208/60/1. This unit will operate at 60Hz or 50Hz.

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:

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.

Note: Steamer must be installed level side to side with a slight tilt front to back to allow for proper draining.

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).

Figure 1.

STACKING STAND

C24EA SERIES ELECTRIC COUNTER CONVECTION STEAMERS

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.

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

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.

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.
