This image displays the two steaming compartments, each with a large circular door handle, and the control panel on the left side. The unit is mounted on a 36-inch cabinet base with adjustable bullet feet at the front and flanged feet at the rear. The cabinet features two doors.

2. Setup and Installation

2.1 Site Requirements

• Location: Install the steamer in a well-ventilated area, away from heat sources and combustible materials. Ensure adequate clearance for maintenance and operation.
• Level Surface: The unit must be placed on a stable, level surface capable of supporting its weight when full. The adjustable bullet feet at the front and flanged feet at the rear allow for leveling.
• Water Supply: A potable water supply with appropriate pressure (typically 20-50 PSI) is required. Install a shut-off valve and a backflow prevention device as per local codes.
• Drainage: Connect the steamer to an open-gap floor drain. Ensure the drain line has a proper slope to prevent standing water.
• Electrical Connection: The unit requires a 115V/60Hz/1-ph electrical supply. Ensure the electrical circuit is properly grounded and protected by a dedicated circuit breaker. Consult a qualified electrician for connection.

2.2 Initial Checks

• Inspect the unit for any shipping damage.
• Ensure all packing materials are removed from inside and outside the compartments.
• Verify all connections (water, drain, electrical) are secure and leak-free.

3. Operating Instructions

3.1 Controls Overview

The Crown DC-2 features independent controls for each compartment, allowing for simultaneous steaming of different products. The control panel includes:

• Power Switch: Turns the unit ON/OFF.
• Timer Controls: Independent automatic timers for each compartment to set steaming duration.
• Pressure Gauge: Displays the internal steam pressure.
• Indicator Lights: Signal operational status (e.g., heating, ready).

3.2 Pre-heating

1. Ensure water supply is connected and turned on.
2. Close compartment doors securely.
3. Turn the main power switch to the 'ON' position.
4. Allow the unit to pre-heat until the pressure gauge indicates optimal operating pressure (typically around 35 PSI) and the 'Ready' indicator light illuminates. This usually takes 15-20 minutes.

3.3 Steaming Procedure

1. Once pre-heated, carefully open the compartment door. Caution: Hot steam will escape.
2. Place food items in appropriate steam pans on the removable shelf supports or slide-out shelf.
3. Slide the pans into the compartment.
4. Close the compartment door firmly.
5. Set the desired cooking time using the independent timer control for that compartment.
6. The steamer will automatically begin the cooking cycle. The timer will count down, and the unit will maintain pressure.
7. Once the timer expires, the steam will automatically shut off for that compartment.
8. Carefully open the door and remove the cooked food. Use heat-resistant gloves.

3.4 Safety Precautions

• Always wear appropriate personal protective equipment (PPE), including heat-resistant gloves and eye protection, when operating the steamer.
• Never block the steam vents or pressure relief valve.
• Do not attempt to open the compartment door while the unit is under pressure. Wait for the pressure to dissipate or for the cycle to complete.
• Ensure the area around the steamer is clear of obstructions and spills to prevent slips and falls.

4. Maintenance

4.1 Daily Cleaning

• After each use, allow the unit to cool down.
• Wipe down all stainless steel interior and exterior surfaces with a damp cloth and mild detergent.
• Remove and clean the removable shelf supports and slide-out shelf.
• Rinse thoroughly and dry to prevent water spots.

4.2 Descaling

Mineral deposits from water can accumulate over time, affecting performance. Regular descaling is crucial.

• The frequency of descaling depends on water hardness. Consult your water supplier for local water quality information.
• Use a commercial descaling solution specifically designed for steam equipment. Follow the manufacturer's instructions for the descaling agent.
• Always ensure the unit is cool and disconnected from power before beginning the descaling process.

4.3 Regular Checks

• Periodically inspect door gaskets for wear or damage. Replace if necessary to maintain a proper seal.
• Check the pressure relief valve for any obstructions.
• Ensure all electrical connections are secure and free from corrosion.
• Schedule professional maintenance annually to ensure optimal performance and safety.
