OM/SM-HY-6E(CE)

The HY-6E (CE) has two independent
cavities, each with its own base-mounted
steam generator. (New model shown).

The unit will be delivered in a heavy carton,
strapped to a wooden skid.

1.0 - Equipment Description

Your Groen HY-6E (CE) 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 (305 x
508 x 64 mm). A 1.5 mm 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 (CE) steamers are equipped with fully
electronic controls and a button-activated,
preprogrammed CLEAN cycle.

The drain system includes a spray condenser, which
helps keep steam from escaping down the
condensate drain.

2.0 - Inspection and Unpacking

Your HY-6E HyPerSteam will be delivered completely
assembled in a heavy shipping carton and attached to
a skid. On receipt, inspect the carton carefully for
exterior damage.

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

Carefully cut the straps around the carton and detach
the sides of the carton from the skid. Be careful to
avoid personal injury. Strap edges may be very
sharp, particularly where cut. Write down the model
number, serial number and installation date. Space
for these entries is provided in the Service Log at the
back of this manual. Keep the manual near the
equipment for reference and update as needed.

CAUTION
THIS UNIT WEIGHS 500 LBS. (250 KG). GET
HELP AS NEEDED AND USE MATERIAL
HANDLING EQUIPMENT TO MOVE IT.

When installing, use material handling equipment to
lift the unit straight up from the skid. Check packing
materials for any loose parts.

3.0 - 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 the equipment
operates.

In some areas of the country, water is low enough in
minerals 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 these
simple precautions:

3.1 Do not rely on unproven water treatments
which are sold as scale prevention or scale
removers. They don’t always work. The best
way to prevent scale is to supply the purest
possible water (10 - 30 ppm TDS).

3.2 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 system is essential.

3.3 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.
Using a water softener will provide longer
generator life, higher steam capacity, and reduce
maintenance requirements.

3.4 If you notice a slowdown in steam production,
check the unit 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.

4.2 Water Connection(s)

Water pressure in the line should be between 30
and 60 PSIG (210 and 420 kPa). If pressure is
above 60 PSIG (420 Kpa), a pressure regulator
will be needed. A 19 mm BSPT connector is
used to attach the water supply to the water inlet
valve. The minimum water feed line diameter is
3/4 inch (13mm). Use a washer in the hose
connection. Do not allow the connection to leak,
no matter how slow it may be.

STEAM GENERATOR VOLUME (7.5 LITERS)
MUST FILL WITHIN THREE MINUTES AND 30
SECONDS.

Water Quality Requirements: For proper steam

generator performance, Total Dissolved Solids
(TDS) should not exceed 30 parts per million
(ppm), and the water pH should be 7.0 or higher.

4.3 Drain Connection

The HY-6E (CE) must be leveled front to back. A

Install a WRAS approved double-check valve or an
equally effective backflow preventive device in the
incoming cold water line at the point of connnection(s)
to the steamer and in compliance with all local
plumbing codes. This installation must be per WRAS

-IRN R160 Schedule 2-15(1). For units with the dual
water connection option, a double-check valve shall be
installed on each water line.

1½ inch (38mm) ID hose may be attached to the
drain pipe (supplied) by means of a hose. There
must be an air gap between the end of the hose
and the building drain.

WARNING
DO NOT CONNECT THE HOSE DIRECTLY TO A
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. THE DRAIN MUST
WITHSTAND HOT WATER.

Install the drain line with a constant downward
pitch. 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.

5.0 - Operation

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

5.1 Controls

Operator controls are on the front right of the unit.
The control panel has the following touch pads and
indicator lights. (Your controls may have either
words or the symbols shown below):

The ON/OFF touch pad gets the
HyPerSteam ready for use, or shuts it
off.

The READY indicator light shows that
the steam generator is at standby
temperature and the cavity is hot
enough to begin steaming.

The CLEANING indicator lights when
the unit is operating in the cleaning
mode.

The SERVICE indicator light shows
when the water level probes have
stopped working, and need to be
cleaned (normally an indication of
lime deposits).

When one probe is not working, the
SERVICE light flashes briefly every
few seconds. When both probes fail,
the light will flash continuously and
the beeper will sound.

The HI TEMP indicator light comes
on when the steam generator is too
hot.

The unit will automatically shut off,
and cannot be turned on again until it
has been serviced.

The TIMING indicator light stays on
when the timer is running.

The CLEAN touch pad is used to start
the automatic 50 minute cleaning
cycle.

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 until

the timer reaches OFF. The steaming stops, a
red light comes on and a beeper sounds.

3 With the timer turned to the ON position, the unit

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

5.2 Operating Procedure

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

5.2.2 Load food into pans in uniform layers. Pans
should be filled to about the same levels, and be
even on top. The maximum allowable weight of
food is 9.8 kilograms (21.6 lbs.) per pan.

5.2.3 Open the door and slide the pans onto the
supports. If you will only be steaming one pan,
put it in the middle position.

5.2.4 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.

• 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
