Equipment Description
Your Groen VRC-3E or VRC-6E Vortex
Connectionless Steamer is designed to give years
of service. It has a stainless steel cavity (cooking
chamber) which is served by an inside water
reservoir which is electrically heated. A powerful
blower circulates the steam in the cavity to increase
heating efficiency.
The cavity holds up to three (VRC-3E) or six (VRC6E) steam table pans (12" x 20" x 2½" deep). An 18
gauge stainless steel case encloses the cavity and
the control compartment that houses electrical
components. Door hinges are reversible (the door
may be set to open from the left or right). Operating
Controls are on the front panel.
VRC-3E and VRC-6E steamers are equipped with
fully electronic controls. These units are readily
identified by their unique control panels. The On-Off
switch is operated by touch pad controls.
From the rear of the VRC-3E and VRC-6E units are
distinguished by the addition of a fuse box, which lets
operators change fuses without removing panels.
The VRC-3E holds three standard 12"x 20"x 2-½"
or two 12"x20"x4" steamer pans.
WARNING
DISCONNECT ELECTRICAL POWER BEFORE
CHANGING FUSES. FAILURE TO DO SO WILL
CAUSE ELECTRICAL SHOCK OR DEATH.
Inspection and Unpacking
The Steamer will be delivered completely assembled
in a heavy shipping carton strapped to a skid. On
receipt, inspect carton carefully for exterior damage.
If damage is evident, notify the local carrier
immediately and file a damage claim. Groen
assumes no liability for damage incurred in transit.
Reconfirm that the voltage at the location is
compatible with the steamer you received.
CAUTION
SHIPPING STRAPS ARE UNDER TENSION AND
CAN SNAP BACK WHEN CUT.
Carefully cut the straps and detach the s ides of the
carton from the s kid. Pull the c arton up off the unit.
Be careful to avoid personal injury or equipment
damage from staples which might be left in the carton
walls.
The VRC-6E holds up to six standard
12"x20"x2-½" or four 12"x20x4" steamer pans.
CAUTION
THE VRC-3E WEIGHS 150 POUNDS (68 KG).
THE VRC-6E WEIGHS 170 POUNDS (77 KG).
YOU SHOULD GET HELP AS NEEDED TO LIFT
THIS WEIGHT SAFELY.
Write down the model number, serial number and
installation date. Keep this information for reference.
Space for these entries is provided at the top of the
Service Log in the back of this manual.
When starting installation, check packing materials
to make sure loose parts such as the drain pan drip
tray are not discarded with this material.

Water Connection(s)
No water connection is needed. The water will be
poured directly into the water cavity reservoir. Avoid
the use of any chemically treated water specifically
filtered water.
Instructions for connecting the optional auto-fill drain
kit are included with the kit.
Drain Connection
The Vortex™ Connectionless Steamer should be
manually drained to the bottom containment pan
supplied by the factory. If the unit is connected to a
drain, do not connect more than two units to one
drain line or pressure from one unit will effect the
second unit.
Stacking Units Instructions
Remove drain containment pan from the bottom of
unit(s). Unscrew to remove adjustable legs from
base of Vortex unit(s). Unfasten nuts and bolts on
stand platform(s). Place Vortex unit(s) on stand
platform. Align the (4) leg holes with the holes in the
platform. Secure Vortex unit(s) to stand platform(s)
using bolts and washers provided in step 2 as shown
in detail “A” of figure 1 on page 7.
For double stack units only:
By loosening the left screw and removing the right
screw provided, mount steam exhaust bracket
assembly to the back panel of the top Vortex unit as
shown in detail “B” of Figure 1 on page 7. Attach the
steam exhaust hose from the bottom Vortex unit’s
steam outlet tube to the top Vortex unit’s steam
exhaust bracket assembly using hose clamps
provided as shown in figure 2 on page 7. (Note:
Steam exhaust hose may need to be cut to fit.)
Steam Vent Assembly Instructions
