Equipment Description
Your Groen HY-3E 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 electrically-heated. A powerful blower circulates the steam In the cavity to increase heating efficiency.
The cavity holds up to three steam table pans (12" x 20" x 2½"). A 16 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 drain system includes a spray condenser, which helps keep steam from escaping from the chamber.
Inspection and Unpacking
The HY-3E steamer holds three standard 12"x 20"x 2-½" pans.
The HY3-E will be delivered completely assembled Write down the model number, serial number and in a heavy shipping carton attached to a skid. On installation date and keep this information for future receipt, inspect the carton carefully for exterior reference. Space for these entries is provided at the damage. top of the Service Log in the back of this manual.
CAUTION CAUTION
SHIPPING STRAPS ARE UNDER TENSION THIS UNIT WEIGHS 180 POUNDS (82 KG). AND CAN SNAP BACK WHEN CUT. YOU SHOULD GET HELP AS NEEDED TO
LIFT THIS WEIGHT SAFELY.
Carefully cut the straps around the carton and detach the sides of the carton from the skid. Pull the carton up off the unit. Be careful to avoid personal injury or equipment damage from staples which might be left in the carton walls.
When starting installation, lift the unit straight up off the skid. Check packing materials to make sure loose parts are not discarded with the material.
Water Conditioning
It is essential to supply the steam generator with these simple precautions: water that will not form scale. Even though the steam generator is engineered to minimize scale formation, scale development depends on the hardness of your water and the number of hours you operate the equipment.
In some areas, water is low enough in mineral content to avoid scale formation. But most water supplies are full of minerals which form scale. It is this scale which could lead to an early component failure.
Your 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 or higher. Please follow
1. Do not rely on unproven water treatments which are sold for scale prevention or scale removal. They don’t always work. The best way to prevent scale is to supply the purest possible water (10 - 20 ppm TDS).
2. If your water contains scale-forming minerals, as most water does, use a well-maintained water softener. Whether an exchangeable softener cartridge or a regenerating system is chosen, a regular exchange schedule is essential.
3. Installing a water meter between the softener and the steamer will provide an accurate gauge of water use, and will help determine when to exchange cartridges or regenerate the softener.
4
Page 5
Using a water softener will provide longer generator life, higher steam capacity, and reduce maintenance requirements.
4. If you notice a slowdown in steam production, have the unit checked 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.
MINIMIZE SCALE PROBLEMS, BY USING AND MAINTAINING A SOFTENER, AND BY CLEANING THE STEAMER REGULARLY.
Groen Steamers are also available with an option for two separate water intakes — one for the steam generator (soft water), the other for the spray condenser (untreated water). The steam generator only uses 14 to 31% of a steamer’s water.
OM-HY-3E
The optional second water connection can reduce treated water requirements.
Since softener 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.
On the HY-3E, the twin water connections are side by side on the rear of the unit. When facing the back of the unit, the treated (softened) water intake is on the right.

The HY-3E Steamer must be leveled front to back, or even pitched slightly to the rear by adjustment of the bulllet feet on the cabinet base.
A 1½ inch (38mm) ID hose may be attached to the drain pipe (supplied).
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 (210 and 420 kPa). If pressure is above 60 PSIG, a pressure regulator will be needed.
A ¾ inch R connector (garden hose type) is used to attach the water supply to the water inlet valve. The minimum water feed line diameter is ½ inch (13mm). Use a washer in the hose connection. Do not allow the connection to leak, no matter how slowly.
WARNING:
DO NOT CONNECT THE DRAIN DIRECTLY TO A BUILDING DRAIN.
There must be at least one-half inch 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.
CAUTION DO NOT USE PLASTIC PIPE. DRAIN MUST BE RATED FOR BOILING WATER.

OM-HY-3E Operation
WARNING
ANY POTENTIAL USER OF THE EQUIPMENT SHOULD BE TRAINED IN SAFE AND CORRECT OPERATING PROCEDURES.
A. Controls
Operator controls are on the front right of the unit. The ON switch gets the HyPerSteam ready for use,
or shuts it off. The READY indicator light shows that the steam generator is at standby temperature, which means that the cavity is hot enough to begin cooking.
WHEN YOU OPEN THE DOOR, STAY AWAY FROM THE STEAM COMING OUT OF THE UNIT. THE STEAM CAN CAUSE BURNS.
WARNING
The timer is used in three ways:
In the OFF position the steam generator stays at a very low boil or “holding” temperature.
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.
When turned all the way to the ON position, the unit steams continuously. The green light stays lit, and the steamer will not time down.
B. Operating Procedure
1. Press the ON switch for the steamer. The steam generator will automatically fill with water, and heat the water until the READY light comes on. The indicator should light within 10 minutes.
2. Load food into pans so that it is 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.
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.
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 switch to the OFF position. The steam generator will automatically drain.
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 to that time. 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 stops.
Controls for the HY-3E are simple, and easy to operate.

Steam Generator and Cooking Chamber
The steamer cavity and steam generator may be cleaned separately. When cleaning is scheduled, or if the CLEAN light is on, follow these simple de­liming instructions. REMEMBER: DON’T ALLOW DE-LIMING AGENTS TO MIX WITH DE­GREASERS.
a. Set the timer to OFF
position.
b. Turn off the steamer for
five minutes.
c. Open the door and allow
the cavity to cool.
d. After the cavity has cooled
five minutes, make sure that the fan has stopped and remove the fan baffle partition by lifting it up and toward the center of the cavity.
e. Wipe out the cavity. Make sure the drain
holes at the back of the cavity are clear of debris.
f. Turn on the steamer and pour two cups of
Groen Delimer Descaler (P/N 114800), Lime­A-Way® or equivalent into the delimer port as shown below. (use a measuring cup or funnel to help prevent spilling). Do not use any de-limer that contains chlorine.
g. Replace fan baffle partition. h. Close door. i. Set the timer for 10 minutes. If the CLEAN light
comes on, repeat the procedure with double the amount of delimer. If the CLEAN light comes on again, call the authorized Groen Service agent in your area. (See listing enclosed with this manual)..
j. WEAR PROTECTIVE
GLOVES AND EYE PROTECTION FOR THIS STEP. When the steamer beeper sounds, turn off the steamer and open the door. After the fan has stopped, remove the fan baffle partition and rinse it well in a sink. Wipe out the cavity completely. If necessary, use a damp nylon pad.
k. Reinstall the fan baffle. l. After 10 minutes, close the door and turn on the
steamer to flush the steam generator tank.
m. Set the time for 10 minutes.
n. When the beeper sounds, open the door and
turn off the steamer. Wipe out the steamer. If it will no longer be used, leave it off. Otherwise, wait 10 minutes and turn it back on. When the READY light comes on, the steamer is ready for operation.
If the CLEAN light stays on:
a. Check that the water supply is on and that the
supply hose is not kinked. With the problem corrected, turn the steamer off or 10 seconds and then re-start.
b. Repeat steam generator cleaning.
Industry experts agree that regular deliming of your steamer is essential for top-notch performance.
“...Forensic evidence from most disabled steamers usually indicates that deliming isn’t happening as frequently as supervisors might think. “The big problem is that operators don’t take care of their steamers,” said (a) dealer sales manager ... “All steamers break” when they’re not delimed, he said. “Deliming is just like changing the oil in your car. No matter how good your car is, if you don’t change the oil, it goes down.”
“You must delime your steamer ...and
when you do delime, do it according to
directions in the owner’s manual. ...For
Groen, you have to take out the racks and
get inside, but the process again is
simple, tool-less and quick, about 25
minutes...”
