Equipment Description

Your Groen HY-6G HyPerSteam Convection

Steamer is designed to give years of service. It has two stainless steel cavities (cooking chambers) which are served by twin, independent atmospheric steam generators which are gas-heated. A powerful blower circulates the steam in each cavity, to increase heating efficiency.

Each cavity holds up to three steam table pans (12" x 20" x 2½"). A 16 gauge stainless steel cabinet encloses the cavities, the steam generators and the control compartment that houses electrical components. Door hinges are reversible (the doors may be set to open from the left or right). Operating

Controls are on the front panel.

Newer model HY-6G steamers (manufactured since

July 1999) are equipped with fully electronic controls and a button-activated, preprogrammed CLEAN cycle. These units are readily identified by their unique control panels. The On-Off switch on older models has been replaced by touch pad controls, and the distinctive symbol for steam is integrated into the panel design. The new model also has fewer panel louvers on the right side.

The drain system includes a spray condenser, which reduces condensate temperature and helps keep steam from escaping through the drain.

OM-HY-6G

Water Quality and Treatment

It is essential to supply the steam generator with water that will not form scale. Even though the steam generator/boiler is engineered to minimize scale formation, scale development depends on the hardness of your water and the number of hours you operate the equipment each day.

Most water supplies contain minerals which form scale.

It is this scale which could lead to an early component failure.

Your local water utility can tell you about the minerals in your water. The water going to the steam generator should have between 10 and 30 parts per million (ppm) total dissolved solids (TDS) and should have a pH

(acidity rating) of 7.0 to 9.0. Please follow these simple precautions:

1. The best way to prevent scale is to use a Groen

PureSteem™ Water Treatment System which has been specifically designed for Groen steamers and combination ovens. Do not rely on unproven

water treatment systems sold for scale prevention and removal.

They are not specifically designed to work with Groen steamers and combination ovens.

2. A well-maintained water treatment system and a regular cartridge replacement schedule is essential.

3. Using a Groen PureSteem™ Water Treatment

System will provide longer steam generator/boiler life, higher steam capacity, and reduce maintenance requirements. To avoid mineral build up in the steam generator, blow down the generator after every 5 hours.

4. If you notice a slowdown in steam production or an increase in deliming, have the steamer checked for scale build-up. This could be an indication that the water treatment cartridges need replacing. Heavy scale reduces the unit’s ability to boil water, and can even cause component failure.

MINIMIZE SCALE PROBLEMS BY INSTALLING

AND MAINTAINING A GROEN PureSteem™

WATER TREATMENT SYSTEM AND BY DELIMING

THE STEAMER REGULARLY.

The Groen HY-6G Steamer features two separate water inlets — one for the steam generator/boiler

(treated water), the other for the spray condenser

(untreated water). The second intake will reduce treatment requirements resulting in significant savings.

The dual water connections are side by side on the rear of the unit. When seen from the back of the unit, the treated water intake is on the left.

Softened water is connected on the left, untreated water on the right. (Old model shown)

OM-HY-6G

OM-HY-6G

Installation and Start-Up

WARNING

THE UNIT MUST BE INSTALLED BY PERSONNEL WHO ARE QUALIFIED TO WORK WITH ELECTRICITY

AND PLUMBING. IMPROPER INSTALLATION CAN CAUSE INJURY TO PERSONNEL AND/OR DAMAGE TO

THE EQUIPMENT. THE UNIT MUST BE INSTALLED IN ACCORDANCE WITH APPLICABLE CODES.

CAUTION

DO NOT INSTALL THE UNIT WITH THE RIGHT SIDE VENTS BLOCKED OR WITHIN 12 INCHES OF A HEAT

SOURCE (LIKE A BRAISING PAN, DEEP FRYER, CHAR BROILER, OR KETTLE).

TO AVOID DRAIN PROBLEMS, LEVEL THE UNIT FRONT TO BACK, OR PITCH IT SLIGHTLY TO THE REAR.

A. Installation

The HY-6G steamer is suitable for installation on or near both combustible and noncombustible surfaces.

Minimum installation clearances are:

Right Side

Left Side

Rear

2 inches

0 inches

6 inches

However, for easy service at least 12 inches clearance is required for the right side of the unit, and it may not be installed within 12 inches of a

heat source, as stated in the Caution above.

The unit must be installed in a well-ventilated room with an adequate air supply. The steamer must be installed beneath a ventilation hood, since gas combustion products exit the appliance.

Any item which might obstruct or restrict the flow of air for combustion and ventilation must be removed.

Do not obstruct the flue cover or any front, side, rear, or top vents after installation.

The area directly around the appliance must be cleared of all combustible material. The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI

Z223.1, latest edition, including the following:

The unit and its individual shutoff valve must be

disconnected from the gas supply system during any pressure testing of that system at test pressures in excess of PSI (3.45 kPa). It must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than PSI (3.45 kPa).

1. Electrical Supply Connection

Provide 115 VAC, 60 HZ, 1 PH, 15 AMP service.

Bring conduit in through open frame on the under-side of cabinet. Local codes and/or the

National Electrical Code should be observed in accordance with ANSI/NFPA 70-1987 (or latest edition). AN ELECTRICAL GROUND IS RE-

QUIRED. The electrical schematic is located in the service compartment and in this manual.

Maximum load is 2 AMPs. In Canada, provide electrical service in accordance with the

Canadian Electrical Code, CSA C22.1 Part 1 and/or local codes.

2222. Gas Supply Connection

Connection to the gas supply can be completed with " NPT pipe or approved equivalent.

Although the immediate connection to the appliance is " NPT, gas supply piping must be large enough to provide 90,000 BTU/hr. Supply pressure must be at least 4.5" W.C. (maximum

14" W.C.) for natural gas or 12" W.C. (maximum

14" W.C.) for LP gas. In Canada, the installation must conform to the Canadian Gas Code, CAN

1-B149, Installation Codes for Gas Burning

Appliances and Equipment and/or local codes.

After the unit has been connected to the gas supply, all gas joints must be checked for leaks.

The knockout hole is sized for a one inch conduit fitting. Pass the wire up the back through this knockout hole to the front.

Make the connections from the front.

7

7

OM-HY-6G

No flame should be used when checking for leaks. A thick soap solution or other suitable leak detector should be used.

For a unit on casters, complete connection to the gas supply with connectors that comply with the standard for connectors for moveable gas appliances, ANSI Z21.69 — latest edition.

Restrain movement of the unit by attaching a cable or chain to the eyelet (provided at the back of the frame) and anchoring the cable or chain to the wall or floor. Make the length and location of the cable such that the unit cannot pull on the gas connection while the cable is connected.

3. Water Connection

A back siphonage device (check valve) must be installed in the incoming cold water line according to local plumbing code. The water line pressure should be between 30 and 60 PSI. A pressure regulator is required above 60 PSI.

A ¾ inch NH (garden hose type) connector is required to connect the water supply to the water inlet valve. The minimum diameter of the water feed line is ½ inch. Use one washer (or, if necessary, two washers) in the hose connection.

Do not allow the connection to have any leak, regardless of how small.

3A Untreated Water Second Connection

As discussed on Page 5, above, the flow of water used for steam suppression in the drain is much greater than the amount of water used to generate steam. An option available with these steamers (see illustration) permits the installer to supply treated water to the steam generator and untreated water to the drain. If your steamer has this “split water” option, the initial fill requirement for treated water is 3.5 U.S. gallons (19 L) within

2.5 minutes. The requirement for treated makeup water is 0.12 gallon (0.45 L) per minute per cavity. A field retrofit kit is available for existing units with no second water connection.

4. Drain Connection

The HY-6G Steamer must be leveled front to back. A 1½ inch (38mm) ID hose may be attached to the drain pipe (supplied) by means of a hose.

DO NOT CONNECT THE HOSE

DIRECTLY TO A BUILDING DRAIN. There must be a free air gap between the end of the hose and the building drain. The free air gap should be as close as possible to the unit drain.

There must also be no other elbows or other restrictions between the unit drain and the free air gap.

Do NOT use plastic pipe. The drain must withstand boiling water.

Install the drain line with a constant downward pitch. Do not allow any water traps in the line.

A trap can cause pressure to build up inside the cavity during steaming, which will make the door gasket leak.

B. INITIAL START-UP

After the HY-6G Steamer has been installed, test it to ensure that the unit is operating correctly.

1. Remove all literature and packing materials from the interior and exterior of the unit.

2. Make sure the water supply line is open.

3. Make sure that the gas supply line is open and that the manual knob on the main gas valve is turned to the “on” position. This valve is located behind the front access panel on the right side of the unit.

4. Turn on electrical service to the unit. The

HY-6G will not operate without electrical power. Do not attempt to operate the unit during a power failure.

5. The steamer will not operate until the pilot burner has been ignited. To light the pilot burner, activate the pilot switch located next to the main gas valve. When the pilot ignition sequence has been successfully completed, a green light - on the pilot switch

(old models) - and on the electrical panel

(new models) will glow.

6. The “trial for ignition” period is roughly 90 seconds. If the pilot burner does not light within about 90 seconds after the switch is activated, the ignition system automatically stops gas flow to the pilot burner and stops the ignition trial. If this happens, turn off the pilot switch and repeat the trial for ignition.

During the initial start-up, the pilot may require several trials for ignition until all the air is bled from the gas piping. Subsequent start-ups should require only about 5 seconds to achieve pilot ignition.

NOTE: See Automatic Operation of Pilot at the end of this section.

7. Once the pilot burner flame has been established (the green light on the pilot switch (old models) or electrical panel (new models) is on), press the “ON” switch for the desired steamer cavity. The steam generator will fill with water.

NOTE: The door MUST be closed for the main burner to work.

8. When the steam generator has filled with water, the burners will ignite automatically.

Within approximately 8-10 minutes the

READY light will come on, indicating that the water has reached its standby temperature.

When the READY light is displayed, you may take any one of the following steps: a. Set the timer to the desired time for timed steaming.

b. Turn the timer knob to the manual ON position for continuous steam.

c. Let the unit stay at standby temperature.

WARNING

WHEN YOU OPEN THE DOOR, STAY AWAY

FROM STEAM COMING OUT OF THE UNIT. THE

STEAM CAN CAUSE BURNS.

9. To shut down the unit, press the ON switch into the off position. The steam generator will then drain. You may also switch off the pilot switch to conserve energy.

10. If the HY-6G Steamer behaves as described, the unit is functioning correctly and ready for use.

Automatic Operation of Pilot

Once the pilot burner is lit, it essentially functions as a standing pilot. In this state, if the pilot is accidentally extinguished (by a very strong gust of wind for example), it will re-ignite automatically. The unit will completely shut down. Operator must turn off and then back on to reset. Then the unit will come back on and resume operation in the mode and with the (running) timer value existing just prior to shutdown. The pilot switch may be turned off during

“off hours” to conserve energy.

After the unit has been running, if the pilot burner ever fails to re-ignite automatically within 90 seconds, wait 5 minutes before you attempt to reactivate it. In the unlikely event that ignition problems persist, contact your authorized Groen

Service Agency.

NOTE: For operation at high altitudes (2000 feet and above) please consult the Groen Food Service

Engineering Department.

WARNING

ALL POTENTIAL USERS OF THE EQUIPMENT SHOULD BE TRAINED IN SAFE AND CORRECT OPERATING

PROCEDURES.

NO ATTEMPT SHOULD BE MADE TO OPERATE THIS EQUIPMENT DURING A POWER FAILURE.

NOTE: Before the steamer can be operated as described in this section, the pilot burner flame must be established. For details see the Initial Start-Up section and the Automatic Operation of Pilot, above.

A. Controls

Operator controls are on the front right of the unit.

The control panel on new models has the following touch pads and indicator lights:

!

The ON/OFF touch pad gets the HyPerSteam ready for use, or shuts it off.

!

!

!

The READY indicator light shows that the steam generator is at standby temperature and the cavity is hot enough to begin steaming.

The DELIME indicator light is lit when the unit is operating in the cleaning mode.

The SERVICE indicator light shows when the water level probes have stopped working, and need to be cleaned (normally an indication of lime deposits).

!

When one probe is not working, the DELIME light flashes briefly every few seconds. If both probes fail the SERVICE light will come on continuously and the beeper will sound.

The HI TEMP indicator light comes on when the steam generator is too hot.

!

!

The unit will automatically shut off, and cannot be turned on again until the steam generator cools and the HI TEMP indicator light goes out.

The TIMING indicator light stays on when the timer is running.

The CLEAN touch pad is used to start the automatic 50 minute cleaning cycle.

The timer is used in three ways:

1 In the OFF position the steam generator stays at a low boil or “holding” temperature.

2 When a cook time is set, the unit steams until the timer runs down to OFF. Steaming stops, the DONE light (a red light on older models) comes on and a beeper sounds.

3 With the timer turned to the ON position, the unit steams continuously. The green light stays lit. The steamer will not time down.

B. Operating Procedure

1. Press the ON switch/pad for the steamer. The steam generator will fill, and heat until the

READY light comes on. (Aprox. 10 minutes.)

2. Load food into pans in uniform layers. Pans should be filled to about the same levels, and should be even on top.

3. Open the door and slide the pans onto the supports. If you will only be steaming one pan, put it in the middle position.

4. Close the door. With the READY indicator lit, take one of the following steps:

!

If you want to steam the food for a certain length of time, set the timer for that period.

The timer will automatically run the steamer for the set time and then turn it off. A red light will come on and a beeper will

sound. Steam production stops.

!

If you want to steam continuously, turn the timer to the manual ON position. A green light will come on. The unit will continue steaming until you stop it by turning the timer to OFF. When steaming continuously

YOU MUST CONTROL STEAMING TIME.
