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 assembledWrite down the model number, serial number and
in a heavy shipping carton attached to a skid. Oninstallation date and keep this information for future
receipt, inspect the carton carefully for exteriorreference. Space for these entries is provided at the
damage.top of the Service Log in the back of this manual.
CAUTIONCAUTION
SHIPPING STRAPS ARE UNDER TENSIONTHIS 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 withthese 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 notrely 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.

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.

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.

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...”
