Equipment Description
The HY-5E steamer holds five standard 12” x 20” x 2½” deep pans.
The HY-3E steamer holds three standard 12” x 20” x 2½” deep pans.
Your Groen HY-3E or HY-5E HyPerSteam Convection Steamer is designed to give years of service. It has a stainless steel cavity (cooking chamber) served by an independent atmospheric steam generator which is electrically heated. A powerful blower circulates the steam in the cavity to increase heating efficiency.
The cavity holds up to three (HY-3E) or five (HY-5E) standard steam table pans. 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.
Model HY-3E steamers and HY-5E steamers are equipped with fully electronic controls and a button activated, pre-programmed DELIME cycle. These units are readily identified by their unique control panels, with touch pad controls, and the distinctive symbol for steam integrated into the panel.
Both units are distinguished by the addition of a “fuse box” which allows the operator to change fuses without removing panels.
The drain system on all models includes a spray condenser, which helps keep steam from escaping from the chamber and cools drain water.
CAUTION
SHIPPING STRAPS ARE UNDER TENSION AND CAN SNAP BACK WHEN CUT.
CAUTION
THE HY-5E WEIGHS 230 POUNDS (104 KG). THE THE HY-3E WEIGHS 180 POUNDS (82 KG). YOU SHOULD GET HELP AS NEEDED TO LIFT THIS WEIGHT SAFELY.
Inspection & Unpacking
The HY-3E or HY5E will be delivered completely assembled in a heavy crate attached to a skid. On receipt, inspect the crate carefully for exterior damage.
Carefully cut the straps around the crate and detach the crate from the skid. Be careful to avoid personal injury or equipment damage from staples which might be left in the crating.
Write down the model number, serial number and installation date. Keep this information for reference. Space for these entries is provided at the top of the Service Log in the back of this manual.
When starting installation, lift the unit straight up off the skid. Check packing materials to make sure loose parts such as the condensate drip tray are not discarded with the packing material.

Water Quality & Treatment
REDUCE SCALE PROBLEMS BY USING AND MAINTAINING A WATER SOFTENER FOR YOUR STEAMER!
Models built since 1998 have a fuse box mounted on the rear.
On both the HY-3E and HY-5E, the dual water connections are side by side on the rear of the unit. When seen from from the back of the unit, the treated (softened) water intake is on the right.
6 OM-HY/3E & HY/5E
It is essential that the steam generator be supplied with water that will not form scale at an unacceptable rate. The boiler was engineered to minimize scale, but its formation depends on water hardness and how much the unit is used.
In some areas of the United States the water is low enough in mineral content to avoid scale build-up. However, most water supplies carry heavy loads of minerals. This
will form scale in the steam generator, reduce its steam output, and possibly cause premature component failure.
Your water utility or local water quality dealer can tell you about the minerals in your water. The water going to the steam generator should have:
1.Between 1 and 30 ppm total dissolved solids (TDS)
2.A pH (acidity rating) of 7.0 - 8.0
3.Total alkalinity less than 120 ppm
4.Silica less than 13 ppm
5.Chlorides less than 30 ppm
6.Sulfates less than 40 ppm
7.Chlorine less than 10 ppm
Please follow these simple precautions:
1.Do not rely on unproven water treatment equipment which is sold for scale prevention or scale removal. They frequently don’t work. The best way to prevent scale is to supply the purest possible water.
2.If your water contains scale-forming minerals, as most water does, use a well maintained water treatment system. Whether an exchangeable softener cartridge or a regenerating system is chosen, a regular exchange system is essential.
3.Installing a water meter on supply line to the steamer will provide an accurate gauge of water use, and will help determine when to exchange cartridges or regenerate the softener. Using treated water will provide longer generator life, higher steam capacity, and reduce maintenance requirements.
4.If you notice a slowdown in steam production, check the steam generator for scale build-up. Heavy scale reduces the unit’s ability to boil water, and can even cause heating elements in the steam generator to overheat and burn out.
5.Steamers are available with two separate water intakes:
one for the steam generator (treated water) one for the spray condenser (untreated water).
The steam generator only uses 14 to 31% of a steamer’s water. Since water treatment systems are typically sized by total GPH (gallons per hour), the second intake could reduce treatment requirements by up to 80%, resulting in significant savings.
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 OR LEFT SIDE VENTS BLOCKED OR WITHIN 12 INCHES OF A HEAT SOURCE (SUCH AS A BRAISING PAN, DEEP FRYER, CHAR BROILER OR KETTLE). TO AVOID DRAINAGE PROBLEMS, LEVEL THE UNIT FRONT TO BACK.
CAUTION
EACH UNIT MUST HAVE A SEPARATE GROUND WIRE FOR SAFE OPERATION.
WARNING
TO AVOID DAMAGE OR PERSONAL INJURY, FOLLOW THE ELECTRICAL SCHEMATIC EXACTLY WHEN CONNECTING THE UNIT.
Installation & Start-Up
ELECTRICAL SUPPLY CONNECTION
1.Panel Removal
Open the wiring and control panel by removing the screws on the right side panel. Slide the panel forward, and set it aside.

Installation & Start-Up
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.
6.Branch Circuit Protection
Each Steamer, including individual units of stacked models, should have its own branch circuit protection and ground wire. Current and power demands for each unit are as shown on page 7.
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.
A ¾ inch female NH connector (garden hose type) is used to attach the water supply to the inlet valve. 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. The dual water standard connection, 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 9.
DRAIN CONNECTION
Level the steamer front to back, or pitch it slightly to the rear (maximum ¼ inch) by adjusting the bullet feet on the stand or cabinet base.
A two inch (50mm) [HY-5E] or 1½ inch (38 mm) [HY-3E] ID hose should be attached to the drain pipe supplied.
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 two inch free air gap.
Install the drain line with a constant downward pitch. IMPORTANT: Do not allow water traps in the drain line. A trap can cause pressure build-up in the cavity, which may cause the door gasket to leak.

Installation & Start-Up
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.
Rear view of (2) HY-5E. NOTE: Some drain parts (elbow, clamps) for single models are packed inside the steamer cavity. Stacked units are factory assembled. Installation is the same for stacked HY-5E and HY-3E units.
Proper Drain Line Connection. Drain Line must have a constant downward pitch of at least 6 mm (¼”) per foot. Connection is 1½” for HY-3E, 2” for HY-5E. (3)HY-3E shown.
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-3E(S), RETROFIT SUPPLEMENT (Part Number 121014). These instructions are also valid for stacking HY-5E steamers.
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.
1.Water Connection
The same water supply connection is used for both units. At the water level inlet valve a 3/4” female NH connector (garden hose type) is used for the water supply. Treated water (softened) is connected to the right valve fitting (looking from the rear of the unit) and untreated water to the left fitting.
2.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.
3.Drain Connection
Steamers must be leveled front to back, or pitched to the rear (maximum 1/4 inch) by adjusting the bullet feet on the cabinet or stand base.
For HY-3E a 1½ inch and for HY-5E a 2 inch ID hose may be attached to the unit drain. It must be rated for boiling water.
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.
COUNTER-MOUNTED UNITS
This section is applicable if the steamer will be mounted to a counter. All four edges of the bottom of the steamer must be sealed with RTV to the counter if 4 inch legs are not used. Counter must be made of a noncombustible material such as metal or tile.

CONTROLS
Operator controls are on the front right of the unit. The control panel has the following touch pads and indicator lights:
The timer is used in three ways:
1.The ON/OFF touch pad gets the HyPerSteam ready for use, or shuts it off.
2.The READY indicator light shows that the steam generator is at standby temperature and the cavity is hot enough to begin steaming.
3.When one probe is covered with lime scale or fails, the DELIME light flashes briefly every few seconds, but the unit will continue to operate. Delime the unit as soon as possible. The DELIME light will flash until power is removed from the unit, or the unit goes through a clean cycle.
4.If the problem continues, both probes may fail. Then the steamer stops working, and the SERVICE light is lit. If DELIMING/CLEANING does not correct, turn off the power and contact an Authorized Groen Service Representative for repair.
5.The DELIME indicator light is lit when the unit is operating in the cleaning mode.
6.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.
7.The TIMING indicator light stays on when the timer is running.
8.The CLEAN touch pad is used to start the automatic 50 minute deliming cycle.
9.The timer is used in three ways:
a.In the OFF position the steam generator stays at a low boil or “holding” temperature.
b.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.
c.With the timer turned to the ON position, the unit steams continuously. The green light stays lit. The steamer will not time down.

Operation
OPERATING PROCEDURE
1.Press the ON switch/pad for the steamer. The steam generator will fill, and heat until the READY light comes on. (About 10 minutes.)
2.Load food into pans in uniform layers. Pans should be filled to about the same levels, and 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.
•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.
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.

IMPORTANT
DO NOT USE ANY METAL MATERIAL (SUCH AS METAL SPONGES) OR METAL IMPLEMENT (SUCH AS A SPOON, SCRAPER OR WIRE BRUSH) THAT MIGHT SCRATCH THE SURFACE. SCRATCHES MAKE THE SURFACE HARD TO CLEAN AND PROVIDE PLACES FOR BACTERIA TO GROW. DO NOT USE STEEL WOOL, WHICH MAY LEAVE PARTICLES IMBEDDED IN THE SURFACE WHICH COULD EVENTUALLY CAUSE CORROSION AND PITTING.
12 OM-HY/3E & HY/5E
To keep your HY-3E or HY-5E Steamer in proper working condition, use the following procedure to clean the unit. This regular cleaning will reduce the effort required to clean the steam generator and cavity.
SUGGESTED TOOLS
1.Mild detergent
2.Stainless steel exterior cleaner such as Zepper®
3.Steam generator de-liming agent, such as Groen Delimer Descaler. A liquid de-liming agent will be easier to use than crystals or powders. See the warning about chlorides.
4.De-greaser
5.Cloth or sponge
6.Plastic wool or a brush with soft bristles
7.Spray bottle
8.Measuring cup
9.Nylon pad
10.Towels
11.Plastic disposable gloves
12.Funnel
PROCEDURE
1.Outside
a.Prepare a warm solution of the mild detergent as instructed by the supplier. Wet a cloth with this solution and wring it out. Use the moist cloth to clean the outside of the unit. Do not allow freely running liquid to touch the controls, the control panel, any electrical part, or any open louver.
b.To remove material which may be stuck to the unit, use plastic wool, a fiber brush, or a plastic or rubber scraper with a detergent solution.
c.Stainless steel surfaces may be polished with a recognized stainless steel cleaner such as Zepper®.
2.Steam Generator and Cooking Chamber
The steamer cavity and steam generator may be cleaned separately. Regular deliming, depending on your steamer usage and local water quality, must be done to enhance performance and prolong the life of your HyPerSteam™ convection steamer. Steamer must be turned off after every use to prevent lime scale buildup - do not run steamer continuously. When cleaning is scheduled, or the SERVICE light is on, follow the simple deliming instructions on the next page.
NOTE: ALWAYS USE HOT PADS OR MITTS WHEN HANDLING HOT STEAMER PANELS OR RACKS. DON’T ALLOW DE-LIMING AGENTS TO MIX WITH DEGREASERS.
RECOMMENDED TOOLS & CLEANERS:
