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
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.
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 (SUCH AS A BRAISING PAN, DEEP FRYER, CHAR
BROILER OR KETTLE).
TO AVOID DRAINAGE PROBLEMS, LEVEL THE UNIT FRONT TO BACK.
1. Electrical Supply Connection
A. Panel Removal
Open the wiring and control panel by removing
two screws on the right side panel. Slide the
panel forward, and set it aside.
B. Supply Voltage
Refer to the heater schematic (Pages 15 and
16) for wiring information.
CAUTION
THE UNIT MUST HAVE A SEPARATE
GROUND WIRE FOR SAFE OPERATION.
The unit must be operated at the rated
nameplate voltage, plus or minus 10 percent.
C. Phase Selection
D. Terminal Block
The terminal block for incoming power is
located at the back of the control compartment.

The ground terminal is located in the wiring The wire specified has to be used, or the unit
compartment above the terminal block.
Minimum size for the ground wire is 10 AWG.
will not meet Underwriters Laboratories and
National Electric Code requirements.
E. Supply wire
To determine the type of wire you need for the
power supply, find the operating voltage and
phase on the unit data plate. Refer to the table
provided on the next page or to the label on the
unit’s back for the correct wire size and
insulation temperature rating. The “Electrical
Supply Connection” label on back right side of
the unit gives directions for proper connection of
the terminal block jumpers.
The knockout hole is sized for a 3/4 inch conduit
fitting.
WARNING
TO AVOID DAMAGE OR PERSONAL
INJURY, FOLLOW THE ELECTRICAL

F. Branch Circuit Protection If you have the twin water connection option, put
the treated water (softened) to the right intake
We strongly recommend that the HY-3E
Steamer have its own branch circuit
protection. Current and power demands for the
different units are as follows:
(facing the rear of the unit), and untreated water
to the left. Connections for both are made as
described above.

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.
