4 OM/SM-HY-6G(CE)

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

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

1.0 - Equipment Description

Your Groen HY-6G (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 gas-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-6G (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-6G 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 550 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.

cold water connection. The water supply must be
provided at a rate of not less than 2.7 liters (0.70
gallons) per minute. Pressure must be 2.0 to 4.0 Bar
(30 to 60 PSI) maximum.

Water quality minimums require totally dissolved
solids (T.D.S.) of 30 parts per million maximum, and
a water pH of 7.0 or greater. If the available water
supply fails to meet these requirements, water
treatment equipment must be provided to ensure
steamer reliability and operating life.

8 OM/SM-HY-6G(CE)

Leave an air gap between the hose and the building
drain, and don’t allow water traps in the hose.

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.

Do not allow the connection to have any leak, regardles

s

of how small.

4.

5 Drain Connection

The HY-6G (CE)Steamer must be leveled front to back.
A 38mm (1½ inch) ID hose may be attached to the drain
pipe (supplied) by means of a hose.

DO NOT

CONNECT THE HOSE DIRECTLY TO

A BUILDING

DRAIN

. 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

.

CAUTIO

N
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 doo

r

gasket leak.

4.

6 Initial Start-Up

After the HY-6G(CE) Steamer has been installed,
test it to ensure that the unit is operating correctly

.

4.6.

1 Remove all literature and packing materials

from the interior and exterior of the unit.

4.6.

2 Make sure the water supply line is open.

4.6.

3 Make sure that the gas supply line is open

and that the manual knob on the main gas
valve is turned t

o the “on” position. This
valve is located behind the front access
panel on the righ

t side of the unit.

4.6.

4 Turn on electrical service to the unit. The

HY-6G(CE) will not operate without electrica

l
power. Do not attempt to operate the unit
during

a power failure.

4.6.

5 The steamer will not operate until the pilot

burner has been ignited. To light the pilo

t
burner, activate the pilot switch located at
the lower front, next to the main gas valve.
When the pilot ignition sequence has been
successful, a green light on the pilot switch
will glow

.

4.6.

6 The “trial for ignition” period is roughly 90

seconds. If the pilot burner does not light
wi

thin about 90 seconds after the switch is
activated, the ignition system automatically
stops gas flow to the pilot burner and stops
the ignition trial. If this happens, turn off the
pilot switch and repeat the trial for ignition.
Du

ring the initial start-up, the pilot may
require several trials for ignition until all the
air is bled from the gas piping. Subsequent
start-ups should require only about 5
seconds to achieve pilot ignition. Reinstal

l
panel(s). NOTE: See Automatic Operation of
Pilot at the end of this section.

4.6.7

. Once the pilot burner flame has been

es

tablished (the green light on the electrical
panel is on), press the ON/OFF touch pad
for the desired steamer cavity. The steam
generator will fill with water

.

NOTE: The door MUST be closed for the
main (high) burner

to work.

4.6.

8 When the steam generator has filled with

water, the main and low burners will ignit

e

au

tomatically. Within 6-8 minutes the
READY light will come on, indicating that the
water has reached its standby temperature.
When the READY light is displayed, you ma

y

take any one of the following steps:

OM/SM-HY-6G(CE) 9

OM/SM-HY-6G(CE)

a. Set the timer to the desired time for timed

steaming.

b. Turn the timer knob to the manual ON

position for continuous steam.

c. Let the unit stay at standby temperature.

WARNING

WHEN YOU OPEN THE DOOR, STAY

AWAY FROM
STEAM COMING OUT OF THE UNIT. THE STEAM
CAN CAUSE BURNS.

4.6.9 To shut down the unit, press the ON/OFF touch
pad into the off position. The steam generator
will then drain. You may also switch off the pilot
switch to conserve energy.

4.6.10 If the HY-6G(CE) Steamer behaves as
described, the unit is functioning correctly and
ready for use.

4.6.11 Automatic Operation of Pilot

Once the pilot burner is lit, it essentially functions as a
standing pilot. In this state, if the pilot is accidentally
extinguished (by a very strong gust of wind for example),
it will re-ignite automatically. The unit will completely shut
down for a few seconds while the pilot is re-ignited.

Then the unit will come back on and resume
operation in the mode and with the (running) timer
value existing just prior to shutdown. The pilot
switch may be turned off during “off hours” to
conserve energy.

After the unit has been running, if the pilot burner
ever fails to re-ignite automatically within 90
seconds, wait 5 minutes before you attempt to
reactivate it. In the unlikely event that ignition
problems persist, contact your authorized Groen
Service Agency.

NOTE: For operation at high altitudes (2000 feet and
above) please consult the Groen Food Service
Engineering Department.

4.7 Gas Type Conversion (See Paragraph 4.3.1 for
important information for gas conversion. Verify
the type of gas to be used).

To change the type of gas used (e.g. G20 to/from
G31) change the following:

Burner injector
Pressure setting on Main Gas Valve
Data plate
Gas pressure Regulator Springs

The governor spring does not need to be changed;
only the pressure setting. ALL CONVERSIONS

MUST BE FOR APPROVED GAS IN THE
COUNTRIES LISTED IN PARAGRAPH 4.3.1

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.

Gas Lockout Indicator and Reset Control

Should the pilot fail to ignite during start-up, a yellow
indicator on the control panel (see page 11) will light
and the supply of gas to the unit will be halted.

When this occurs, the ignition process may not be
started again for five minutes. After that time, press the
Lockout Reset Switch located behind the front panel
and attempt to start the unit again. If the lockout
continues to occur after three attempts, contact your
Groen Service Agency for assistance.

5.2 Operating Procedure

5.2.1 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.)

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 CONTROL
STEAMING TIME.

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

5.2.5 Open the door. Remove the pans from the
steamer, using hot pads or oven mitts to protect
your hands from the hot pans.

5.2.6 To shut down the unit, press the ON/OFF touch
pad OFF. The steam generator will drain.
