INSTALLATION DIAGRAM NOTES The Product Identification Plate located on the right side service panel specifies the electric power requirements. For each unit, the installer must provide a ground connection and a separate fused disconnect switch. Catastrophic damage will result from shifting the more than 3° out of level while power is turned on at the unit’s main power switch.
PREPARATION FOR INSTALLATION Select and prepare the operating location before permanently positioning the unit. Protect the unit and packaged components during site preparation. Do not select the operating location or start installation before checking the electric power, gas, and water quality requirements to assure proper drainage, ventilation, and safety.
PROTECTING THE OVEN / STEAMER Electric Power Requirements The characteristics of the electric power supply must match the power requirements specified on the Oven/Steamer product identification plate. The plate is secured to the outside of the right-side access panel as illustrated in Figure 2-2.Gas Supply Requirements WARNING NEVER EXCEED 14”/355.6 mm WATER COLUMN (1/2 psi) GAS PRESSURE.
WATER QUALITY REQUIREMENTS Contact a local water treatment specialist for an on-the-premises water analysis. The recommended minimum feed water quality requirements for the Oven/Steamer are listed in Table 2-2. Table 2-2. Minimum Supply Water Quality Requirements Total Dissolved Solids less than parts per million Silica less than...
WATER SUPPLY SYSTEM Select a water supply system that fulfills the following elements: the two different inlet water supplies (softened and untreated) must provide a minimum dynamic pressure of 35 psi (2.4 kg/cm ) and a maximum static pressure of 60 psi (4.1 kg/ ).
Page 37
The dimension drawings (Figure 2-2) specify all dimensions and clearances required for proper operation and service of each Oven/Steamer covered in this manual. The service access panel is on the right side of the unit. Select an operating location that allows access to the right side of the unit for service.
INSTALLATION INSTRUCTIONS After selecting and preparing the Oven/Steamer operating location, the oven/steamer can be positioned and installed. When installation is complete, perform all start-up checks to verify proper installation and operation. POSITION AND LEVEL THE OVEN/STEAMER NOTE: If there is not enough clearance behind the to install the drain, electrical, and water lines, skip this procedure and continue with Install and Connect the Free Air Vented Drain Lines.
Refer to figure 2-3 and bolt the legs to the Oven/Steamer frame. All four legs must be installed for proper mounting of the unit. Place the oven/steamer upright on its four legs. Figure 2-3. Leg Bolts Oven placed on counters, if placed on a plane different from the one suggested by the producer, must be sealed (see point A, fig.
Page 40
POSITION AND LEVEL THE OVEN/STEAMER For free-standing models, the appliance needs to be levelled: small differences in level of the supporting surface can be eliminated with the adjustable feet (by screwing or unscrewing them). A significantly uneven or sloping stance can affect the operation of the oven adversely.
APPLIANCE EQUIPPED WITH CASTERS ELECTRIC • Adequate means must be provided to limit the movement of the appliance without depending on or the transmitting stress to the electrical conduit. • The appliance shall be installed using flexible conduit. GAS-FIRED • The installation shall be made with a connector that complies with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 –...
INSTALL AND CONNECT THE FREE AIR VENTED DRAIN LINES The drain outlets and the drain vent at the top of the unit must be free air vented to equalize the pressure in the with the atmosphere. Generating steam causes pressure to increase in the unit; cold water flow into the condenser creates a vacuum (low pressure) in the condenser.

TESTING THE AUTOMATIC GAS VALVE AND BURNER CONTROL SYSTEM Figure 2-9: automatic gas valve NOTE: A smoky, strong smelling vapor fills the cooking compartment and exhaust ports during initial startup. This condition is normal, please refer to Initial Operation and Cleaning, at the end of this chapter.
START-UP CHECK LIST This inspection checks proper electrical water and drain connections to the Oven/Steamer, and verifies basic operation of the oven/steamer. WARNING Equipment damage and faulty operation will result if the gas, water or electrical supplies fall below requirements. This may be caused by other equipment on the same supply lines.
Page 55
START-UP CHECK LIST If not already done during installation, pressure test the gas supply line as described in Testing Gas Supply Lines and Burner Controls. NOTE: A smoky, strong smelling vapor fills the cooking compartment and exhaust ports during initial startup after installation. Refer to Initial Operation and Cleaning, at the end of this chapter.
INITIAL OPERATION AND CLEANING During shipment, components in the cooking compartment and steam generator are protected by an oily, non-toxic coating. During the first cooking cycle after shipment, this coating vaporizes, filling the cooking compartment and exhaust ports with a smoky, strong smelling vapor.

CHAPTER 3. PREVENTIVE MAINTENANCE AND TROUBLESHOOTING Introduction Maintenance on the Oven/Steamer must be performed on a regular basis to keep the unit running properly. Follow the maintenance instructions in this chapter and problems will be kept to a minimum. As with any preventive maintenance schedule, the frequency of oven/ steamer maintenance must be increased if necessary, depending on equipment usage and water quality.
PREVENTIVE MAINTENANCE AND TROUBLESHOOTING DAILY MAINTENANCE Blowdown Steam Generator Blowdown the steam generator at least once every 8 hours according to Steam Generator Cleaning Clean interior and exterior of the four according to Cleaning and Shut-Down instructions. Inspect the Cooking Compartment Vent Cooking vapors leave the compartment through the compartment exhaust vents labeled and on the dimensions drawings.
PREVENTIVE MAINTENANCE AND TROUBLESHOOTING Immediately you notice that the oven is not performing as it should, descale the boiler hopefully you won’t be too late. Use a specific product intend for descaling; do not use powdered sulphonic acid material, liquid phosphoric acid. The following chart lists steam generator capacities.
Page 61
PREVENTIVE MAINTENANCE AND TROUBLESHOOTING Spill or leak procedures - Limit spill. Cover the contaminated surface with sodium bicarbonate or a soda ash-slaked lime mixture (50-50). Mix and add water necessary to form slurry. Scoop up slurry and wash residue down drain with excess water. Wash site with soda ash solution.
