OM-HY-6CAV 5
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”).
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).
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.
The drain system includes a spray condenser, which suppresses any steam escaping
from the chamber and cools condensate water going into the drain.
Equipment Description
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.

6 OM-HY-6CAV
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.
The HY-6SG Gas Model is suitable for installation on combustible and noncombustible
floors. Minimum installation clearances for the HY-6SG are:
Right Side 2 inches
Left Side 4 inches
Rear 6 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.
1. Electrical Supply Connection
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
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.
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.
CAUTION
SHIPPING STRAPS ARE UNDER TENSION.
THEY CAN SNAP BACK VIOLENTLY AND
CAUSE INJURY WHEN CUT.
CAUTION
MAKING ELECTRICAL OR MECHANICAL

Installation
D. Water supply lines should be sized to provide for maximum water use (the
total of the boiler and condenser spray) as shown in the following table:
Maximum Water Consumption-gal/hr (L/hr)
CNGB/3 boiler only 12.9 (48.8)
CNEB/1 (24KW) boiler only 8.2 (31.0)
CNEB/1 (36KW) boiler only 12.5 (47.3)
CNEB/1 (48KW) boiler only 16.9 (64.0)
HY-6 HyPlus Steamer condenser spray only
AT 40 PSI (280 kPa) 47.4 (180)
AT 60 PSI (410 kPa) 57.0 (215)
3. Drain Connection
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.
IMPORTANT
IMPROPER DRAIN CONNECTION
WILL VOID WARRANTY.
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.
Controls: Timers are located on the front right side of the unit. There are two timers
— one each for the upper and lower cavities.
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.
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.
A. Operating Procedure
1. Turn on the unit’s water supply.
2. Turn on electrical power to the unit.
3. On models HY-6SG and HY-6SE, start boiler and allow steam pressure to
develop. Refer to OM-CNGB/3 or OM-CNEB/1 operator manuals for assistance in
operating steam boilers. On model HY-6SM, turn on the steam supply.
4. Load food into pans so that it is in uniform layers. For best results, pans should
be filled to about the same levels, and should be even on top.
5. Open the door and slide the pans onto the supports. If you will only be steaming
one pan, put it in the middle rack position.
6. Close the door.
NOTE: The door must be closed before steam will enter the cavity. If the door is
opened when the timer is on, the steam will stop.
7. Turn the timer to one of the following settings:
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.
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.
8. Open the door.
9. Using a pad or oven mitt to protect your hands, remove the pans from the
steamer.
10. To shut down the unit, turn the Timer to the OFF position.
