PLUMBING. IMPROPER INSTALLATION CAN CAUSE INJURY TO PERSONNEL AND/OR DAMAGE
TO THE EQUIPMENT. THE UNIT MUST BE INSTALLED IN ACCORDANCE WITH APPLICABLE
CODES.
NOTICE: DO NOT BLOCK THE RIGHT SIDE VENTS, AND DO NOT INSTALL WITHIN 12 INCHES OF A HEAT
SOURCE SUCH AS A BRAISING PAN, DEEP FRYER, CHAR BROILER OR KETTLE.
NOTICE: LEVEL THE UNIT FRONT TO BACK, OR PITCH IT SLIGHTLY TO THE REAR, TO AVOID DRAINAGE
PROBLEMS.
CAUTION: DO NOT LOCATE THE CABINET DIRECTLY OVER A FLOOR DRAIN OR SINK. HUMIDITY OR
WATER FROM A DRAIN WILL DAMAGE ELECTRICAL PARTS OF A UNIT.
WARNING: TO AVOID DAMAGE OR INJURY, FOLLOW THE WIRING DIAGRAM EXACTLY WHEN CONNECTING
A UNIT.
CAUTION: DO NOT USE PLASTIC PIPE. DRAIN MUST BE RATED FOR BOILING WATER.
WARNING: DO NOT CONNECT THE DRAIN DIRECTLY TO A BUILDING DRAIN.
WARNING: BLOCKING THE STEAM GENERATOR OR CAVITY DRAIN SCREEN MAY BE HAZARDOUS.
IMPORTANT: IMPROPER DRAIN CONNECTION WILL VOID WARRANTY.
WARNING: WHEN YOU OPEN THE DOOR, STAY AWAY FROM STEAM COMING OUT OF THE UNIT. STEAM
CAN CAUSE BURNS.
WARNING: BEFORE CLEANING THE OUTSIDE OF THE STEAMER, DISCONNECT THE ELECTRIC POWER
SUPPLY. KEEP WATER AND CLEANING SOLUTIONS OUT OF CONTROLS AND ELECTRICAL
COMPONENTS. NEVER HOSE OR STEAM CLEAN ANY PART OF THE UNIT.
WARNING: ALLOW COOKING CHAMBERS TO COOL BEFORE CLEANING.
WARNING: CAREFULLY READ THE WARNINGS AND FOLLOW THE DIRECTIONS ON THE LABEL OF EACH
CLEANING AGENT. USE SAFETY GLASSES AND RUBBER GLOVES AS RECOMMENDED BY
DELIMING AGENT MANUFACTURER.
WARNING: DO NOT MIX DE-LIMING AGENTS (ACID) AND DE-GREASERS (ALKALI) IN THE STEAM
GENERATOR OR ON THE COOKING CHAMBER WALLS.
WARNING: DO NOT PUT HANDS OR TOOLS INTO THE COOKING CHAMBER UNTIL THE FAN HAS STOPPED
TURNING.
WARNING: DO NOT OPERATE THE UNIT UNLESS THE REMOVABLE RIGHT SIDE PANELS HAVE BEEN
RETURNED TO THEIR PROPER LOCATIONS.
NOTICE: DO NOT USE A CLEANING OR DE-LIMING AGENT THAT CONTAINS ANY SULFAMIC ACID OR ANY
CHLORIDE, INCLUDING HYDROCHLORIC ACID. IF THE CHLORIDE CONTENT OF ANY PRODUCT
IS UNCLEAR, CONSULT THE MANUFACTURER.
NOTICE: USE NO DE-GREASER THAT CONTAINS POTASSIUM HYDROXIDE OR SODIUM HYDROXIDE OR
THAT IS ALKALINE.
WARNING: USE OF ANY REPLACEMENT PARTS OTHER THAN THOSE SUPPLIED BY GROEN OR THEIR
AUTHORIZED DISTRIBUTOR VOIDS ALL WARRANTIES AND CAN CAUSE BODILY INJURY TO THE
OPERATOR AND DAMAGE THE EQUIPMENT. SERVICE PERFORMED BY OTHER THAN
FACTORY-AUTHORIZED PERSONNEL WILL VOID ALL WARRANTIES.

The HY-6E has two independent cavities, each
with its own base-mounted steam generator.
(New model shown)
Equipment Description
Your Groen HY-6E HyPerSteam Convection Steamer is
designed to give years of service. It has two stainless
steel cavities (cooking chambers) which are served by
twin, independent atmospheric steam generators which
are electrically-heated. A powerful blower circulates the
steam in each cavity to increase heating efficiency.
Each cavity holds up to three steam table pans (12" x 20"
x 2½"). An 18 gauge stainless steel case encloses the
cavities, the steam generators and the control
compartment that houses electrical components. Door
hinges are reversible (the doors may be set to open from
the left or right). Operating Controls are on the front
panel.
HY-6E steamers are equipped with fully electronic
controls and a button-activated, preprogrammed CLEAN
cycle. The On-Off switch is a touch pad control, and the
distinctive symbol for steam is integrated into the panel
design.
The drain system includes a spray condenser, which
helps keep steam from escaping down the condensate
drain.
Water Conditioning
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.
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 MAINTAINING A GROEN PureSteem™
WATER TREATMENT SYSTEM AND BY
DELIMING THE STEAMER REGULARLY.
The Groen HY-6E 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 right.
