Equipment Description
Your Groen HY-5G or (2)HY-5G HyPerSteam Convection Steamer is designed to give years of service. It has a stainless steel cavity (cooking chamber) which is served by an independent atmospheric steam generator which is gas-heated. A powerful blower circulates the steam in the cavity to increase heating efficiency.
Each cavity holds up to five steam table pans (12" x 20" x 2½" deep). An 18 gauge stainless steel case encloses the cavity, the steam generator and the control compartment that houses electrical components. Door hinges are reversible (the door may be set to open from the left or right). Operating Controls are on the front panel.
The HY-5G steamer is equipped with fully electronic controls and a button-activated, pre-programmed CLEAN cycle. These units are readily identified by their unique control panels. The On-Off switch is operated by touch pad controls, and the distinctive symbol for steam is integrated into the panel.
The HY-5G steamer holds five standard 12" x 20" x 2½" steamer pans.
The drain system on all models includes a spray condenser, which helps keep steam from escaping from the chamber and cools drain water.

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 30 and 40 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.
OM-HY-5G
HY-5G
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.
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 MAINTA INING A GROEN PureSteem™ WATER TREATMENT SYSTEM AND BY DELIMING THE STEAMER REGULARLY.
The Groen HY-5G 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.
(2)HY-5GF
The second water connection can reduce treated water requirements.

Installation and Start-Up
WARNING THE UNIT MUST BE INSTALLED BY PERSONNEL WHO ARE QUALIFIED TO WORK WITH GAS, ELECTRI CITY AND PLUMBING. IMPROPER INSTALLATION CAN CA USE INJURY TO PERSONNEL AND/OR DAMAGE TO THE EQUIPMENT. THE UNIT MUST BE INSTALLED IN ACCORDANCE WITH APPLICABLE
CODES
DO NOT INSTALL THE UNIT WITH THE RIGHT OR LEFT SIDE VENTS BLOCKED OR WITHIN 12 INCHES OF A HEAT SOURCE (SUCH AS A BRAISING PAN, DEEP FAT FRYER, CHARBROILER OR KETTLE).
TO AVOID DRAINAGE PROBLEMS, LEVEL THE UNIT FRONT TO BACK, OR PITCH IT SLIGHTLY TO THE REAR.
.
CAUTION
A. Installation
The HY-5G steamer is suitable for installation on or near both combustible and noncombustible surfaces. Minimum installation clearances are:
Right Side 2 inches Left Side 2 inches Rear 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:
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 2½ AMPs. In Canada, provide electrical service in accordance with the Canadian Electrical Code, CSA C22.1 Part 1 and/or local codes.
2. Gas Supply Connection
Connection to the gas supply can be completed with ½” NPT pipe or approved equivalent. Although the immediate connection to the appliance is ½” NPT, gas supply piping must be large enough to provide 62,000 BTU/hr/cavity. 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. Check all gas connections for leaks prior to unit operation.
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 ½ 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 ½ PSI (3.45 kPa).
1. Electrical Supply Connection
Provide 115 VAC, 60 HZ, 1 PH, 15 AMP service. Bring wire in through hole on the lower left back panel. Each cavity requires a separate cord for connections. Local codes and/or the National
6
After the unit has been connected to the gas supply, all gas joints must be checked for leaks.
No flame should be used when checking for leaks. A thick soap solution or other suitable
leak detector should be used.
OM-HY-5G
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.
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.
2. Water Connection(s)
Install a check valve to prevent back flow in the incoming cold water line, as required by local plumbing codes. Water pressure in the line should be between 30 and 60 PSIG and must deliver a flow rate of 1.5 to 3.0 gallons per minute. If pressure is above 60 PSIG, a pressure regulator will be needed.
¾ inch female NH connectors (garden hose type) are used to attach the water supply to the inlet valves. One connector is for the steam generator (treated), the other is for the spray condenser (untreated). Minimum inside diameter of the water feed line is ½ inch. Use a washer in the hose connection. Do not allow the connection to leak, no matter how slowly. Do not over tighten hose connections. Treated (softened) water goes to the right (seen from the rear of the unit), and untreated water to the left. Connections for both are made as shown on Page 5. Though not recommended, an adapter to use a single water intake is available, P/N
138473.
3. Drain Connection
Level the steamer front to back, or pitch it slightly to the rear (maximum ¼ inch) by adjusting the optional legs or bullet feet on optional stand.
A 2 inch ID hose may be attached to the drain pipe (supplied).
WARNING:
DO NOT CONNECT THE DRAIN DIRECTLY TO A BUILDING DRAIN. BLOCKING THE DRAIN IS HAZARDOUS.
CAUTION DO NOT USE PLASTIC PIPE. DRAIN MUST BE RATED FOR VERY HOT WATER.
Install the drain line with a constant downward pitch.
IMPORTANT: Do not allow water traps in the line. A trap can cause pressure build-up in the cavity, which may cause the door gasket to leak.
4. Factory Stacked Units
This section is applicable only if you are installing factory-stacked units. If you plan to stack steamers yourself, whether purchasing a new one for stacking or a kit to stack two units you already own, you will require OM-HY-5G(S), RETROFIT SUPPLEMENT (Part Number 121087).
Installing stacked steamers is similar to installing a single unit. The steamers are stacked and assembled at the factory and delivered with the water connections and drain hoses required for a single point connection.
A. Water Connection
The same water supply connection is used for both units. At the water inlet valves, ¾ inch female NH connectors (garden hose type) are used for the water supplies. There are two connections to be made. Treated water (softened) is connected to the right valve fitting (looking from the rear of the unit) and untreated water to the left fitting.
B. Electrical Supply Connection
Separate, individual electrical connections will be required for each steamer in the stack. Each Steamer must have its own branch circuit protection.
C. Gas Connection
Separate gas connections are required for each steamer in the stack. Gas supply must be adequate under all conditions as listed on
page 6.
7
OM-HY-5G
D. Drain Connection
Steamers must be leveled front to back, or pitched to the rear (maximum ¼ inch) by adjusting the bullet feet on the stand.
Ensure that there is a free air gap between the end of the unit drain and the building drain. This gap should be as close as possible to the unit drain. Do not allow elbows or restrictions between the unit and the free air gap.
A 2 inch ID hose may be attached to the unit drain. It must be rated for very hot water.
WARNING
DO NOT CONNECT THE UNIT DRAIN DIRECTLY TO THE BUILDING DRAIN.
CAUTION DO NOT USE PLASTIC PIPE. DRAIN MUST BE
RATED FOR VERY HOT WATER.

Initial Start-Up
OM-HY-5G
After the HY-5G 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-5G 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 behind the sliding door located on the right cover panel. When the pilot ignition sequence has been successfully completed, a green light - on the pilot switch 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 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 (high) burner to work.
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 STE AM C OMING OU T OF TH E UN IT. 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-5G 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 for a few seconds while the pilot is re-ignited. 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.
8. When the steam generator has filled with water, the low and main burners will ignite automatically. Within 8-10 minutes the READY light will come on, indicating that the

A. Controls
Operator controls are on the front right of the unit. The HY-5G control panel 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 CLEANING 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 fails, the SERVICE light flashes briefly every few seconds, but the unit will continue to operate. De-lime the unit as soon as possible.
If the problem continues, both probes may fail. Then the steamer stops working, the light will flash repeatedly and the beeper will sound. At this point you must turn off the
power and contact an Authorized Groen Service Representative for repair.
! 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.
10
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. At that time steaming stops, a red light 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/OFF touch pad for the steamer. The steam generator will fill, and heat until the READY light comes on. (About 8-10 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.
OM-HY-5G
! 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.
WARNING
WHEN YOU OPEN THE DOOR, STAY AWAY FROM THE STEAM COMING OUT OF THE UNIT. THE STEAM CAN CAUSE BURNS.
5. Open the door. Remove the pans from the steamer, using hot pads or oven mitts to protect your hands from the hot pans.
6. To shut down the unit, press the ON/OFF touch pad to OFF. The steam generator will automatically drain.
4. Close the door. With the READY indicator lit, take one of the following steps:
