INTRODUCTION

1.1 The Groen Service Concept

Since 1907 Groen has been in the business of designing and
manufacturing the finest commercial appliances for the food
service industry. Chefs, cooks and kitchen support personnel
have come to depend upon the quality of construction and
the reliability of operation.

Groen, in turn, depends upon our service centers and their field
service personnel to keep the equipment in top operating condi­tion. In order to do this, our designs are made with service and
reliability in mind.

Once the Groen equipment is sold, manufactured, delivered and
installed, our reputation is clearly in your hands. As part of our
team, we value your efforts and input to our product design.

We will do all we can to make your job of keeping the equip­ment in perfect working order as easy as we can. Together, we
will keep our customers satisfied.

1.2 Groen Certified Service

The Vortex Connectionless Steamer has been carefully designed
to provide many years of efficient and reliable service. Part of the
quality program is Groen Certified Service.This includes:

• Groen certifies that all equipment delivered to our customers
has been inspected and tested for compliance with the
specifications.

• Groen certifies that all parts required for service and
maintenance will be readily available.

• Groen certifies that this manual will be updated by means of
periodic service bulletins to provide the most up-to-date
information for field maintenance and service personnel.

1.3 Warranty & Non-Warranty Repair

Groen Warranty provisions are clearly presented in the
customer’s Operator Manual.

Certain procedures for the cleaning and/or adjustment
of the Vortex Connectionless Steamer are presented in this man­ual for reference, but not warranty related.

This non-warranty symbol is used throughout the
manual to tell you which items and activities are
NOT covered by the equipment warranty.

1.4 Safety

The Groen Vortex Connectionless Steamer has been designed
from the start with safety in mind. This includes safety to the
operating and maintenance personnel, safety to the facility in
which the equipment is installed and safety to the equipment
itself.

The steamer contains several devices, which are specifically used
to prevent unsafe conditions. If they are disconnected, make sure
they are reinstalled properly and tested before the steamer is
operated.

The safety precautions in this manual are in accordance with
ANSI 535 Standard. Three different signal words alert you to a
hazardous situation:

DANGER,WARNING,AND CAUTION

DANGER:

The signal word DANGER indicates that a

hazardous situation is about to happen and, if not avoided,
will result in death or serious injury.

2.1 Controls

Operator controls are on the front right of the unit.

The VRC-3E and VRC-6E control panels have the following touch
pads and indicator lights:

• The ON/OFF touch pad gets the Vortex™ ready for use,

or shuts it off.

• The HOLD indicator light shows that the cavity is at holding

temperature.

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

• The low water probe signals the ADD H20 indicator light to

illuminate when it’s time to add water.

• The open and closed position of the drain valve allows the

unit to be filled with water or drained.This is also used to
manually reset the unit.

• If fitted with an optional water fill drain kit, the high water

probe will automatically control the water level.

• The HI TEMP indicator light comes on when the bottom of

the water reservoir becomes too hot.The unit will
automatically shut off, and cannot be turned on again until
the water reservoir cools down.

• The HI TEMP light will remain illuminated until the controls

are turned on and the unit temperature is low enough to
restart. Then reset the manual reset latch as indicated on the
bottom label.

• When power has been interrupted to the Vortex or the HI

TEMP light has come on, the RESET light will illuminate. The
drain handle will need to be momentarily opened or closed
to extinguish light.

The timer is used in three ways:

1. In the HOLD position the steam generator stays at a low boil
or “holding” temperature. Factory set at 180°F.

2. When a cook time is set, the timing light will illuminate.
The unit steams until the timer runs down to DONE.At that
time steaming stops, the DONE light illuminates and a
beeper sounds.

3. When the timer is turned to the ON position, the unit
steams continuously.The green ON light will stay illuminated.

OPERATION

2.2 Operating Procedure

NOTE: When the unit is first installed, or anytime incoming

power is interrupted, the RESET light will illuminate. Momentarily
turn the drain handle to open then back to close to reset the
unit and extinguish the RESET light.

1. With the cooking chamber water reservoir “empty” press
the ON/OFF touch pad. The ADD H20 light will illuminate
when the door is opened. Pour water into the reservoir
through the door.When the water level comes up to the
hi probe the reservoir is full and 3 beeps will sound. Close
door.The fan and contactor will turn on after 15 seconds.

2. Set the time knob to the ON position. The contactor can be
heard cycling to pulse energy into the heating elements.The
unit will be ready in about 20 minutes.

3. Load food into pans in uniform layers. Pans should be filled
to about the same levels, and should not be mounded.

4. Open the door and slide the pans onto the supports. If you
will only be steaming one pan, put it in the middle position.
Some foods will cause foam. When cooking foods that
foam, such as shrimp, put an empty solid 2” deep pan in
the bottom slot of the pan racks.

5. Close the door and 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 beeper
will sound. Steam productions stops. The red DONE light will
illuminate.

• If you want to steam continuously, turn the timer to the
manual ON position. The green ON light will illuminate.
The unit will continue steaming at a temperature of 203° F
or higher.

• If you want to maintain food at holding temperature turn
the timer to the “HOLD” position. The hold light will not
illuminate if the temperature is above 180 degrees. Open
door to cool.

WARNING

When you open the door,

stay away from the steam

coming out of the unit.

the steam can cause burns.

6. To remove pans from cavity, open the door. Remove the
pans from the steamer, using hot pads or oven mitts to
protect your hands from the hot pans.

7. To shut off the unit, press the ON/OFF touch pad.

8. To drain the remaining water in the water reservoir, move
the drain handle to the OPEN position.The drain pan will
not hold all of the water in the reservoir.Allow water to cool
before draining. Pull drain pan slowly from the unit to avoid
sloshing.

the rear of cavity as shown in the diagram.

3.3a Cut out a 3” square of insulation around the hole center.

3.4 Drill a 5/8” diameter hole. Note: make sure to remove all

burrs on both in and out side of the cavity, any burrs will
cause the fitting to leak.

3.4a Install bulkhead fitting and teflon washer from the inside

of the cavity, and thread jam nut from outside to hold in
place and seal, refer to drawing.

3.5 Thread brass elbow into the bulkhead fitting from outside

of the cavity with barb end pointing toward the back of the
unit as shown on the drawing.

3.6 On the back panel of the unit, locate the 1” diameter

pre-drilled hole and pop out the plug.

3.7 Install the water valve from inside of the unit with the 8-32

screws from outside thru the pre drilled holes.

3.8 Connect hose auto fill line to the outlet port on the valve

and to the brass elbow on the side of the unit thru the
hose clamps, see drawing. Use the tension hose clamps to
secure on both ends of the hose, one on the valve and the
other on the brass barb. Note, if you are installing the kit in

a span capacity unit cut hose to fit.

3.9 Connect the two hose electrical leads to the solenoid valve.
The leads are marked with WV-1 and WV-2.The wiring
harness has these two leads loose inside the unit.

4 Water drain installation steps.

4.1 The condensate drain line needs to be disconnected before
the left side cabinet panel can be replaced.

4.1a From the bottom of the unit just right of the drain valve
unscrew the condensate drip bracket.

4.1b From the inside, loosen the tension clamps and remove
the bracket from the hose and the hose from the
condensate line.

4.1c Slide the tension clamps off of the hose and use them on
next step.

4.1d Install one end of the supplied hose 3/8”ID x 30” long
on the condensate line where the condensate trap to
drain hose were installed before, pull the other end of the
hose through the hole where the bracket was mounted.
Reinstall the inside tension clamp.

4.2 Guide the hose loose end thru the uncovered hole to the
outside bottom of the unit as drawing shows.

4.3 Thread the hose drain assembly onto the unit drain valve,
see drawing.

4.4 Connect the 3/8” diameter x 30” long hose loose end to
the plastic barb fitting on the drain assembly and reuse
the other tension hose clamps.

4.4a If you are installing a kit on a 3 pan model cut this 3/8”
x 30” long hose to fit.

4.5 A 10ft piece of hose is supplied with this kit, it can be cut
to length and used with the elbow to help route the hose
to the proper drain location.

4.6 For single units cut the long hose to length as needed to
route it to facility drain. Note hose end must have at least
a 2” gap from the floor drain, do not use traps.

4.7 For double stack units, a 6.5” long piece of hose can be
cut to join the upper and lower cavities by using the
supplied tee on the bottom unit, the supplied elbow on
the top unit and a piece to connect the two cavities as
shown. Permit a 2” air gap from the floor drain. Do not
use traps.

5 Test to ensure the final assembly of the drain line

allows the water to flow freely.

Loops or kinks in the hose will cause back pressure which
may cause the door to pop open during draining.

General Specifications

Atmospheric Steamer

The Vortex Connectionless Steamer has an electric heated water
reservoir to provide atmospheric steam at a temperature of
approximately 212° F, at sea level.The water reservoir has electric
water level sensors. When filled to the high water sensor, it has
a capacity of four gallons.

Controls

• ON-OFF power button

• 90 minute timer, with a continuous steam setting

• A HOLD light which indicates when the cavity is at a holding

temperature

• An ADD WATER light to indicate water needs to be added

to the reservoir

Performance Features

• The steamer comes up to ready in about 20 minutes from a
cold start

• A side mounted city fan provides efficient steam distribution
throughout the cavity

• An ADD WATER light to indicate water needs to be added to
the reservoir, or the steamer will automatically shut down

• To drain the water reservoir, turn the drain handle to the
OPEN position, and the water will drain into the drain pan
below the cavity

• 15 second delay before motor starts each time door is
opened

Installation

The steamer requires 208, 240 or 480 volt power supply.
The 208 and the 240 volt steamers can operate on single or
three phase power, but the 480 volt steamer is three phase only.

Water Supply Requirement

No water hookup is required, unless the steamer has the water
option. The water fill option requires a 1/2" diameter water hose,
with a 3/4" hose connector and 30 to 60 PSI water pressure.

Electrical Specifications

Electrical requirement are, 208, 240 or 480 volts, single
(208 or 240 volts steamers) or three phase power supply.
Note: 480-volt steamers are three phase only.

The three phase steamers are shipped with a cord set ready to
plug in.
