CHAPTER 1 INTRODUCTION

To use a Gemini gas steamer safely and effectively, each operator must read and understand this Chapter completely before starting operation. The owner(s) and operator(s) of the steamer should retain these instructions in an easily accessible location for future reference and training.

The owner(s) and operator(s) of the steamer must be aware that steam can cause serious injuries and equipment damage. Pay particular attention to the Operational Safety section of this chapter, and the WARNINGS and CAUTIONS displayed in this manual and on the equipment.

A. GAS LEAK INSTRUCTIONS

If the operator smells gas, or suspects there is a gas leak, he should immediately refer to the posted gas leak instructions. The posted instructions are provided by the local supplier and supersede any other instructions. Until the leak is stopped, observe the following precautions in addition to the posted instructions.

DO NOT ATTEMPT TO START OR OPERATE a Gemini steamer during a power outage.

DEATH, INJURY, AND/OR EQUIPMENT DAMAGE could result from the improper installation of a steamer.

Before starting a recently installed or repaired steamer, be sure it has been installed by qualified personnel according to the instructions found in the separate Installation and Maintenance Manual.

WARNING

Do not light or start any appliance.

Do not touch any electrical switch.

Do not use any phone in the building.

Immediately call the gas supplier from a phone away from the building. Follow the gas supplier’s instructions.

If the gas supplier cannot be reached, call the fire department.

B. OPERATIONAL SAFETY

The safe and effective operation of any steamer depends upon proper installation, use, maintenance, and repair. Operational safety must encompass all of these factors. This Operational Safety section outlines the minimum safety policies that should be considered when using one or more Gemini steamers. It is assumed that any operational safety program must be tailored to the specific site and use of the equipment.

Burn hazards are present in any professional food service operation. When using the steamer, observe the following precautions.

Remember at all times that steam can cause severe burns.

When checking inside the steamer always open the door slowly and stand to the side and back away from the steamer. Water leaking from the door gasket can be a sign of a blocked drain. If the drain is blocked, hot water can accumulate inside the compartment and spill out when the door is opened.

Open the door slightly to allow steam to vent before looking or reaching into cooking compartment.

Do not reach into the cooking compartment until the steam has cleared.

Do not reach into steamer or handle hot items without wearing heatproof gloves. Wet or damp gloves conduct heat, and may cause burns when touching hot items.

Do not use anything but your hands to operate the ON/OFF levers/switches or any other control on the steamer.

Do not block the vents on the side or rear of the unit or obstruct the flow of combustion and ventilation air to the steamer. Do not store articles on top of the unit.

The steamer requires a minimum of service if properly operated and maintained by trained personnel. The following steps will help keep the steamer in a safe, efficient operating condition.

1. Do not store or leave combustible materials near the steamer. Keep the area around and under the steamer free of combustible materials.

2. Non slip draining mats should be on the floor in front of the steamer to prevent slipping accidents from spilled water.

3. Train all personnel who will use the steamer. Make sure personnel know how to operate the steamer, clean the interior and exterior, drain the unit, and descale the steam generator.

4. This steamer may be equipped with a three-prong (grounding) plug for your protection against shock hazard and should be plugged directly into a properly grounded three-prong receptacle. Do not cut off or remove the grounding prong from the plug of a steamer equipped with an electrical cord.

5. Periodically inspect the flue of the steam generator for signs of sooting or blockage. Contact a Cleveland Range authorized service representatives to service the steamer if any improper operation of the burner system is suspected.

6. Operating personnel must be able to recognize problems, and report them so that corrective actions can be taken by trained personnel as outlined in the troubleshooting charts found in the back of this manual and in the separate Installation and Maintenance Manual.

7. Conduct regular steamer inspections. Check for water line leaks, door seal and drain leaks, clogged drain, steam generator scale buildup, and steamer control malfunctions.

8. Follow the instructions for steamer maintenance found in this manual and Chapter 3 of the Installation and Maintenance Manual.

9. Before each use of the steamer, inspect both compartments for drain and screen blockage. Inspect both door gasket assemblies, and all slide racks for proper installation and cleanliness.

10. Allow only Cleveland Range authorized service representatives to service the steamer.

11. Use only factory authorized repair parts.

12. Maintain written records of steamer maintenance and service. Each record should include at least:

The date of the service or maintenance.

A description of the service, maintenance or repair performed. Include part numbers if applicable.

Copies of purchase order(s) and invoice(s) for repair parts and service.

The name and signature of the person performing the maintenance or service.

CHAPTER 2 GENERAL OPERATION

A. MAIN EXTERNAL POWER SWITCH

Usually the steamers main power switch is left ON. If the main external power switch was left in the OFF position, turn it ON as follows.

MAIN POWER SWITCH

1. Check that the water supply valves are open.

Gemini

2. Turn the ON/OFF levers/switches counterclockwise to the OFF position.

3. The TIMED/MANUAL switch and timer settings are not important in this procedure. The control panel circuits are not powered while the ON/OFF levers/switch is set to OFF.

4. Refer to the main power switch in Figure 2-1, and turn on electric power to the steamer. The steam generators will immediately start blowdown cycles. The blowdown cycle lasts 3 minutes.

B. DOOR INTERLOCK SWITCH

The steamer compartments of the Gemini Steamer are equipped with automatic steam cutoff switches, which turn OFF the production of steam to a cooking compartment whenever the door to that compartment is opened. NOTE: Even though the continued production of steam ends as soon as a door is opened, it may take up to a minute for residual steam in the system to clear from the steam lines and the cooking compartment. To avoid possible injury always wait until this residual steam has cleared before reaching into the cooking compartment.

C. POWER ON (AUTOMATIC FILL)

When each steamer compartment is turned ON, it automatically fills its steam generator with water. Use this procedure at the beginning of a shift to prepare the steamer for operation without starting steam generation. When ready to start steam cooking, begin either the Timed or Manual Operating Procedure.

DRAIN LINE

COLD WATER SUPPLY LINES

Figure 2-1 Main External Power Switch

1. Press the TIMED (top) end of the TIMED/MANUAL switch (for ON/OFF models set the selector switch to OFF..

2. Turn the ON/OFF lever/switch (see Figure 2-2 or 2-3), depending on model, clockwise to the ON position to energize the steamer control panel. The red indicator light on the control panel lights, the combustion blower turns ON to purge the generator and water fills the steam generator.

Figure 2-2 ON/OFF Leve

(Located below lower compartment)

Figure 2-3 ON/OFF Switch

(Located on control panel)

NOTE: The ON/OFF lever/switch must be turned fully to the ON position to START the steamer.

3. When the generator is full, the steamer automatically stops water flow.

4. Once the water has reached the minimum operating level, the blower turns OFF and the pilot/standby burner lights to heat the water to the standby temperature.

D. LIGHTING AND SHUTDOWN INSTRUCTIONS

DO NOT TRY TO LIGHT THE BURNERS OR PILOT WITH A FLAME. THE PILOT AND BURNERS ARE SELF IGNITING. The Gemini Steamer has an electronic ignition system, which automatically lights the pilot and burners, senses the flame and controls gas flow. This provides precise burner control, safety ignition, and shutdown.

The following START-UP SUMMARY is for quick reference ONLY. For safe operation and use of this equipment, the operators should comply with all safety and operating instructions in this manual.

DEATH, INJURY OR EQUIPMENT DAMAGE may result from an improperly adjusted gas control and ignition system. Do not alter any adjustments on this electronic control or gas valve.

If adjustment is required, contact an authorized service center. Cleveland Range is in no way responsible for the operation or safety of this equipment if the controller, valve, or igniter probe are adjusted by anyone other than a Cleveland Range authorized service representative.

WARNING

Lighting Instructions

1. Turn the ON/OFF lever/switch clockwise to the ON position.

Blower will start and boiler will fill with water (about 3 minutes).

Pilot will attempt to light for 90 seconds.

If no ignition occurs the system will automatically reset in 6-7 minutes.

2. System may be reset manually by turning the ON/OFF lever/switch counterclockwise to the OFF position for 5 minutes and then back to ON.

3. Turn ON a cooking compartment. (Not required for “Instant ON” models)

Blower will start and main burner will light.

4. Each compartment has its own control system, and must be started independently.

Shutdown Instructions

Turn the ON/OFF lever/switch counterclockwise to the OFF position. The burners and pilots will immediately be extinguished and the unit will begin the automatic 3-minute blowdown cycle and drain. NOTE: Each compartment has its own control system, and must be shut off independently.

E. INSPECTING THE COOKING COMPARTMENT

At the back of the cooking compartment, a drain screen covers the drain (Refer to Figure 2-4). The screen prevents large food particles from entering and blocking the drain line. Any blockage of the drain line or

screen can reduce drainage from the cooking compartment resulting in reduced cooking performance, equipment damage, and a hazard to the operator. A blocked or slow drain may cause:

Hot water to collect in the compartment and spill out when the compartment door opens.

Pressure fluctuations in the compartment, resulting in steam leaks around the door gasket, or compartment implosion.

Reduced convection in the compartment, reducing cooking performance.

Before every steaming operation, inspect the cooking compartment and remove any food scraps or debris from the racks, walls, and floor of the compartment. Pay particular attention to the drain and drain screen.

Steam leaks around the door, cooking compartment flooding, reduced cooking performance, and compartment implosion can be caused by a blocked drain or drain screen. Inspect and clean the drain and drain screen before each use.

CAUTION

Figure 2-4 Compartment

Drain Screen

DRAIN SCREEN

1. DO NOT USE the steamer if water stands in the drain opening. Arrangements must be made immediately to clean the drain in accordance with the instructions found in the Preventative Maintenance and Troubleshooting section of this manual.

2. Remove any food or debris that is blocking the drain or screen.

3. Be sure the screen covers the drain. The screen prevents large pieces of food from entering and blocking the drain.

F. PREHEATING THE STEAMER

Preheating the steamers can help insure that the best productivity and consistent cooking is obtained. To preheat each steamer, run a cooking cycle of approximately 15 minutes with no food in the cooking compartments.

NOTE: If using a steamer with a timer, set only a 1 minute cooking time for the purpose of preheating, since

the timer will only begin to countdown once the steamer has reached a cooking temperature.

BEFORE PREHEATING, inspect and clean the compartment. After preheating, the compartment will be too hot to inspect and clean safely.

G. DESCALING REQUIRED LIGHT FEATURE

When the programmed number of hours have elapsed, the “DESCALE REQUIRED” light will turn on, indicating that descaling of the steam generator must be done (See Figure 2-5). More information on this feature and the descaling procedure can be found in the Maintenance section of this manual, Chapter 6, Part A (4), Monthly/Weekly Maintenance.
