OM-HY-6CAV
Equipment Description
The Groen HY-6 HyPlus Steamer is designed to
bring you years of service. It has two stainless steel
cavities (cooking chambers) and a control
compartment, which houses the electrical
components and steam valves. In each cavity, a
powerful blower circulates the steam for increased
heating efficiency. Each cavity will hold up to three
steam table pans (12" x 20" x 2-1/2").
Operator Controls are located on the front panel.
Model HY-6 HyPlus steamer cavities are mounted
on a cabinet base and require a low pressure (3-15
PSI) steam supply. Models HY-6SG and HY-6SE
have steam boilers (gas-fired or electrically heated,
respectively) built into their cabinet bases. Model
HY-6SM has no steam generator and requires a
“clean” steam supply suitable for food contact.
A 16 gauge stainless steel case encloses the
cavities and the control compartment that house
electrical components. The door hinges are
reversible (the doors may be hung to open from the
left or right).
The drain system includes a spray condenser, which
suppresses any steam escaping from the chamber
and cools condensate water going into the drain.
This Operator Manual applies only to the cavities (cooking chambers) of your HY-6S Series HyPlus
Convection Steamer. Refer to separate boiler unit manual provided where appropriate — OM-CNGB/3 for
HY-6SG, and OM-CNEB/1 for HY-6SE. There is no separate manual for the HY-6SM direct steam model.
WARNING
THE UNIT MUST BE INSTALLED BY PERSONNEL WHO ARE QUALIFIED TO WORK
WITH ELECTRICITY AND/OR GAS, AND PLUMBING. IMPROPER INSTALLATION CAN
CAUSE INJURY TO PERSONNEL AND/OR DAMAGE TO THE EQUIPMENT. THE UNIT
MUST BE INSTALLED IN ACCORDANCE WITH ALL APPLICABLE CODES.
HyPlus S Series steamers have two
steam compartments with individual
controls.

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 ALL APPLICABLE CODES.
Getting Started
CAUTION
SHIPPING STRAPS ARE UNDER TENSION.
THEY CAN SNAP BACK VIOLENTLY AND
CAUSE INJURY WHEN CUT.
CAUTION
MAKING ELECTRICAL OR MECHANICAL
CHANGES TO THE UNIT WITHOUT APPROVAL
FROM THE GROEN FOOD SERVICE
ENGINEERING DEPARTMENT MAY VOID
WARRANTIES.
Immediately inspect the unit for external and internal
damage when it is delivered. Report any damage to
the carrier. After inspection, keep the unit in its
shipping container until it is ready to be installed.
The unit must be installed level. Level the unit front
to rear and left to right, by adjusting its feet. Check
for levelness by using a spirit level on top of the
cabinet, and checking in both directions.
1.
Electrical Supply Connection (See Page 8)
A.
On models HY-6SG and HY6-SE, power is
supplied to cavity controls and blower from the
boiler base, and no other electrical connections
are required.
B.
On model HY-6SM, you must provide 115 Volt
Alternating Current, 60 Hz, single phase, 15
AMP service. Local codes and/or the National
Electrical Code should be observed in
accordance with ANSI/NFPA-70-1987 (or latest
edition). AN ELECTRICAL GROUND IS
REQUIRED.
C.
The electrical schematic is located in the
electrical enclosure and in this manual. In
Canada provide electrical service in accordance
with the Canadian Electrical Code, CSA C22.1,
Part 1 and/or local codes.
2.
Water Supply Connection (See Page 8)
A.
Models HY-6SG and HY-6SE feature two
separate water inlets – one for the steam boiler
(treated water), the other for the spray
condenser (untreated water). The second
intake will reduce treatment requirements
resulting in significant savings.
B.
For the HY-6SM, provide a 3/8” NPT pipe
connection for untreated water at the rear of the
unit. A back siphonage device (check valve)
must be installed, complying with local plumbing
codes. The water pressure should be between
30 and 60 PSI (210 to 410 kPa). A pressure
regulator is required above 60 PSI (410 kPa).
C.
The condenser spray uses 0.70 to 0.95 gallons
of water per minute (2.6 to 3.6 liters per minute)
at 30 to 60 PSI (210 and 410 kPa). The spray
will only operate when a steamer cavity
(cooking chamber) is in operation.
The HY-6SG Gas Model is suitable for installation on
combustible and noncombustible floors. Minimum
installation clearances for the HY-6SG are:
Right side — Two inches
Left Side — Four inches
Rear — Six inches
HY-6SE and HY-6SM models have no minimum
clearance requirements, but room should be
provided so that the units may be serviced. The use
of approved flexible tubing and quick disconnect
attachments will be helpful in allowing the unit to be
moved. For example, 24 inches right side clearance
is needed for proper servicing, unless the unit can be
easily moved.
Please refer to the appropriate operator manual
(OM-CNGB/3 or OM-CNEB/1) for models HY-6SG
and HY-6SE steam boiler installation.

Drain Connection (See Page 8)
A.
On all HyPlus models (HY-6SG, HY-6SE and
HY-6SM), the drain connection is made at the
rear of the unit, using a 1-1/4” NPT pipe. Do
NOT use plastic pipe — the piping must be able
to withstand steam and hot water. Extend the
drain piping to a nearby floor drain. Piping of 1 1/4" NPT (or 1 - 1/2" NPT) is acceptable for
distances of six feet or less. If the distance to
the drain is further than six feet, use 2" NPT
piping.
B.
Install the drain line with a constant downward
pitch. 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. A vertical air gap must be
maintained between the drain line and the
building drain, unless otherwise specified by
local plumbing codes.
Leave an air gap between the hose and the building
drain, and don’t allow water traps in the line.

Operation
WARNING
ANY POTENTIAL USER OF THE EQUIPMENT SHOULD BE TRAINED IN SAFE AND
CORRECT OPERATING PROCEDURES.
7. Turn the timer to one of the following settings:
Controls: Timers are located on the front right
side of the unit. There are two timers — one each for
the upper and lower cavities.
a. If you want to steam for a definite period of
time, set the timer to that time. Steam will
be delivered to the cavity for that time, and
then stop. A buzzer and red LED will
indicate that the timed cycle is complete.
Steam flow stops.
The timer is used in two ways:
1. Turning the timer to any setting delivers steam to
the cavity until the timer runs down to OFF. At
that time a red LED switches on and a beeper
sounds and the steam flow to the compartment
stops.
b. If you want to steam continuously, turn the
timer to the ON position. A green light will
come on. Steam will be delivered to the
cavity until the timer is returned to OFF.
2. When turned all the way to the ON position, the
timer allows continuous steaming. A green LED
is turned on, and the timer does not time down.
Steam continues until the timer knob is turned to
the OFF position.
8. Open the door.
9. Using a pad or oven mitt to protect your
hands, remove the pans from the steamer.
A. Operating Procedure
