The C24EA6 and C24EA10 convection steamers are dual compartment, electric, pressureless steam cookers with an internal electric steam generator that maintains water temperature at approximately 195° F. At 208V and 480V, the C24EA6 is rated at 17.2kW, and the C24EA10 is rated at 25.6kW. At 240V, the C24EA6 is rated at 19.7kW, and the C24EA10 is rated at 26.4kW.

Model C24EA6 can accommodate three 2 1/2" deep (6.4 cm) steam pans per compartment. Model C24EA10 can accommodate five 2 1/2" deep (6.4 cm) steam pans per compartment. The C24EA6 and C24EA10 electric convection steamers are designed for cooking vegetables, eggs and other foods, in commercial kitchens. Each compartment has a 0-60 minute timer, as well as a constant steam feature. The buzzer requires manual shutoff. The steamer is equipped with a cabinet base with flanged feet for floor mounting.

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" (91.4 cm) at the front of the steamer, 15" (38 cm) above the steamer and 18" (45.7 cm) on the right and left sides of the steamer.

LEVELING AND ANCHORING

Position the steamer in its final installed location. Place a level on the horizontal area of the cabinet. Adjust the feet to level the steamer in both the left-to-right and front-to-rear directions.

Steamers should be elevated in the front just enough, about provide proper draining. Do this by rotating the adjustable feet in the proper direction 1 to 1 turns after leveling. Check drainage in the steamer compartments by pouring a small amount of water in the compartment. All the water should drain.

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

Water Supply Connection

Connect the treated cold water supply line to

the

/4" (19 mm) (male hose thread) inlet.

Connect the untreated cold water supply line to

the

/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.

Filter System

If you decide to not install a scale-reducing filter system designed for steam equipment or use another manufacturer’s system other than that recommended by Vulcan Hart, please use these guidelines.

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.

• If you are going to delime the unit with a deliming agent recommended for a pressure steam boiler and stainless steel generators, and you are on city or treated well water, you still must have a carbon block filter installed and maintained. Carbon block filters remove the chlorine and chloramine disinfectants from the water. Chlorine and chloramines will erode the boiler or steam generator and will result in a vessel failure, which is not covered under warranty.

• Water feed lines to the steamer must be flushed before final connection. Particles in the water could build up in the water and steam valves or clog tubing and components that maintain the water level and pressure in the boiler or steam generator. If the water supply is not free of sediment or is cloudy after several minutes of flushing, a sediment filter must be installed before use.
