WARNING: THE UNIT MUST BE INSTALLED BY PERSONNEL 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: SHIPPING STRAPS ARE UNDER TENSION AND CAN SNAP BACK WHEN CUT.

CAUTION: DO NOT INSTALL THE UNIT IN ANY WAY WHICH WILL BLOCK THE SIDE VENTS, OR

WITHIN 12 INCHES OF A HEAT SOURCE SUCH AS A BRAISING PAN, DEEP FRYER, CHAR
BROILER OR KETTLE.

CAUTION: LEVEL THE UNIT FRONT TO BACK, OR PITCH IT SLIGHTLY TO THE REAR, TO AVOID

DRAINAGE PROBLEMS.

WARNING: FOLLOW THE WIRING DIAGRAM EXACTLY WHEN CONNECTING A UNIT TO AVOID

DAMAGE OR INJURY.

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 DRAIN IS HAZARDOUS.

Important: Improper drain connection will void warranty.

Important: Do not allow any water traps in the line. A trap can cause pressure to build up inside the

cavity during steaming, which will make the door gasket leak.

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 CHAMBER 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).

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 PANEL HAS BEEN

RETURNED TO ITS PROPER LOCATION.

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: DO NOT USE ANY 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 RESULT IN
BODILY INJURY TO THE OPERATOR AND DAMAGE THE EQUIPMENT. SERVICE BY
OTHER THAN FACTORY-AUTHORIZED PERSONNEL WILL VOID ALL WARRANTIES.

OM-HY-5E/HY-3E

The HY-3E steamer holds three
standard 12" x 20" x 2½” steamer
pans.

The HY-5E holds up to five pans.

Equipment Description

Your Groen HY-5E or 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 electrically­heated. A powerful blower circulates the steam in
the cavity to increase heating efficiency.

The cavity holds up to five (HY-5E) or three (HY-3E)
steam table pans (12" x 20" x 2½" deep). 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.

HY-3E and HY-5E steamers are equipped with fully
electronic controls and a button-activated, pre­programmed CLEAN cycle. These units are readily
identified by their unique control panels. The On­Off switch is operated by touch pad controls, and
the distinctive symbol for steam is integrated into
the panel. The new models also have fewer panel
louvers on the right side.

From the rear HY-3E and HY-5E units are
distinguished by the addition of a fuse box, which
lets operators 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.

Inspection and Unpacking

The Steamer will be deliv ered completely
assembled in a heavy shipping carton strapped to a
skid. On receipt, inspect carton carefully for exterior
damage.

CAUTION
SHIPPING STRAPS ARE UNDER TENSION AND
CAN SNAP BACK WHEN CUT.

Carefully cut the straps 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.

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.

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, check packing materials
to make sure loose parts such as the condensate
drip tray are not discarded with this material.

Models built since 1998 have a fuse box
mounted on the rear.

Water Conditioning

It is essential to supply the steam generator with 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 per day you operate
the equipment.

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 more than

10 to 30 parts per million
(ppm) total dissolved solids (TDS) and should have a
pH (acidity rating) of 7.0 or higher. 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 treatm

ent 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 unitʼs ability to
boil water, and can even cause component failure.

MINIMIZE SCALE P

ROBLEMS BY USING AND
MAINTAINING A SOFTENER AND BY CLEANING
(DELIMING) THE STEAMER REGULARLY.

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.

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 OR LEFT SIDE VENTS BLOCKED OR WITHIN 12 INCHES
OF A HEAT SOURCE (SUCH AS A BRAISING PAN, DEEP FAT FRYER, CHARBROILER OR KETTLE).

TO AVOID DRAINAGE PROBLEMS, LEVEL THE UN

IT FRONT TO BACK.

1. Electrical Supply Connection

A. Panel Removal

Open the wiring and control panel by removing
screws from the right side panel. Slide the
panel forward, and set it aside.

B. Supply Voltage

The unit must be operated at the rated
nameplate voltage.

C. Phase Selection

Refer to steamer schematics (Pages 20-21) for
wiring information.

CAUTION
EACH UNIT MUST HAVE A SEPARATE
GROUND WIRE FOR SAFE OPERATION.

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

compartment near the terminal block.

E. Supply W ire

To determine the type of wire you need for the
power supply, find the operating voltage and
number of phases on the unit data plate. Refer
to the table below or to the label on the unitʼs
back for correct wire size and temperature
rating. The equipment grounding wire must
comply with the National Electrical Code (NEC)
requirements. The schematic on the inside of
the unitʼs right side cover gives directions for
proper connection of the termina

l block jumpers.
The specified wire must be used, or the unit will
not meet Underwriters Laboratories and NEC
requirements. The knockout hole is sized for a
¾ inch conduit fitting on the HY-3E and for a
one inch conduit fitting on the HY-5E.

WARNING

TO AVOID DAMAGE OR PERSONAL INJURY,
FOLLOW THE ELECTRICAL SCHEMATIC
EXACTLY WHEN CONNECTING THE UNIT.
