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 delivered 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
gene

rator 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

unp

roven 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
Sy

stem will provide longer steam generator/boiler

li

fe, 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 PROBLEMS 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.

Branch Circuit Protection

Each Steamer, including individual units of
stacked models, should have its own branch
circuit protection and ground wire. Current

and power demands for each unit are as shown
on Page six.

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 and must
deliver a flow rate of 1.5 to 3.0 gallons per
minute. If pressure is above 60 PSIG, a
pressure regulator will be needed.

A ¾ inch female NH connector (garden hose
type) is used to attach the water supply to the
inlet valve. Minimum inside diameter of the
water feed line is ½ inch. Use a washer in the
hose connection. Do not allow the connection to
leak, no matter how slowly. The dual water
standard connection, treated (softened) water
goes to the right (seen from the rear of the unit),
and untreated water to the left. Connections for
both are made as shown on Page Five.

3. Drain Connection

Level the steamer front to back, or pitch it
slightly to the rear (maximum ¼ inch) by
adjusting the bullet feet on the stand or cabinet
base.

A 2 inch [HY-5E] or 1½ inch [HY-3E] ID hose
may be attached to the drain pipe (supplied).

WARNING

:

DO NOT CONNECT THE DRAIN DIRECTLY TO
A BUILDING DRAIN. BLOCKING THE DRAIN IS
HAZARDOUS.

There must be a 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
free air gap.

CAUTION
DO NOT USE PLASTIC PIPE. DRAIN MUST BE
RATED FOR BOILING WATER.

Install the drain line with a constant downward pitch.

IMPORTANT: Do not allow water traps in the
line. A trap can cause pressure build-up in the
cavity, which may cause the door gasket to leak.

4. Factory Stacked Units

This section is applicable only if you are installing
factory-stacked units. If you plan to stack steamers
yourself, whether purchasing a new one for stacking
or a kit to stack two units you already own, you will
require OM-HY-3E(S), RETROFIT SUPPLEMENT
(Part Number 121014). These instructions are also
valid for stacking HY-5E steamers.

Installing stacked steamers is similar to installing a
single unit. The steamers are stacked and
assembled at the factory and delivered with the
water connections and drain hoses required for a
single point connection.

A. Water Connection

At the water inlet valve a ¾ inch female NH
connector (garden hose type) is used for the
water supply. The dual water connection has
two connections to be made. Treated water
(softened) is connected to the right valve fitting
(looking from the rear of the unit) and untreated
water to the left fitting.

B. Electrical Supply Connection

Separate, individual electrical connections
will be required for each steamer in the
stack. Each Steamer must have its own
branch circuit protection.

C. Drain Connection

Steamers must be leveled front to back, or
pitched to the rear (maximum ¼ inch) by
adjusting the bullet feet on the cabinet or stand
base.

For HY-3E a 1½ inch and for HY-5E a 2 inch ID
hose may be attached to the unit drain. It must
be rated for boiling water.

Operation

WARNING

ANY POTENTIAL USER OF THE EQUIPMENT MUST BE TRAINED IN SAFE AND CORRECT OPERATING
PROCEDURES.

A. Controls

Operator controls are on the front right of the unit.

The HY-5E and HY-3E control panels have the
following touch pads and indicator lights:

1 The ON/OFF touch pad gets the HyPerSteam

ready for use, or shuts it off.

2 The READY indicator light shows that the steam

gene

rator is at standby temperature and the

cavity is hot enough to begin steaming.

3 When one probe is covered with lime scale or

fails, the DELIME light flashes briefly every few
seconds, but the unit will continue to operate.
De

-lime the unit as soon as possible. The
DELIME light will flash until power is removed
from the unit, or the unit goes through a clean
cyc

le.

4 If the problem continues, both probes may fail.

Then the steamer stops working, and the

SE

RVICE light is lit. If DELIMING/CLEANING

does

not correct, turn off the power and
contact an Authorized Groen Service
Re

presentative for repair.

5 The DELIME indicator light is lit when the unit is

ope

rating in the cleaning mode.

6 The HI TEMP indicator light comes on when the

steam generator is too hot.

The unit will automatically shut off, and cannot
be t

urned on again until the steam generator

cools and the HI TEMP indicator light goes out.

8 The TIMING indicator light stays on when the

timer is running.

9 The CLEAN touch pad is used to start the

au

tomatic 50 minute cleaning cycle.

9

OM-HY-5E/HY-3E

The timer is used in three ways:

1 In the OFF position the steam generator

stays at a low boil or “holding” temperature.

2 When a cook time is set, the unit steams

un

til the timer runs down to OFF. At that
time steaming stops, a red light comes on
and

a beeper sounds.

3 With the timer turned to the ON position, the

un

it steams continuously. The green light
stays lit. The steamer will not time down.

B. Operating Procedure

1. Press the ON/OFF touch pad for the steamer.
The steam generator will fill, and heat until the
READY light comes on. (About 10 minutes.)

2. Load food into pans 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.

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 for that period.
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 production stops.

• 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.

WARNING

WHEN YOU OPEN THE DOOR, STAY AWAY
FROM THE STEAM COMING OUT OF THE UNIT.
THE STEAM CAN CAUSE BURNS.

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/OFF touch
pad to OFF. The steam generator will
au

tomatically drain.
