Equipment Description
The Groen Convection Combo™ consists of a stainless steel cooking chamber, an air heating
compartment with electric heating elements and dual fans, a steam generator with electric heating
elements, and a control compartment housing electrical components.
All major components of the Convection Combo are encased in a 16 gauge stainless steel cabinet. Glass
fiber insulation, 1 to 2 inches thick, lines the cabinet.
The oven has a double door with two large, tempered glass windows in each door. Oven viewing lights are
mounted between the inner and outer doors. Separate hinges allow easy access to the space between the
doors for window cleaning and light fixture maintenance. A condensate collection tray at the bottom diverts
condensate to the oven drain. An optional solid door is available. The solid door does not provide viewing
lights.
All operator controls are on the front panel. Standard controls permit the Convection Combo to operate in
four modes:
1.
2.
3.
4.
As a convection oven
As a self-contained, pressureless steamer
As a combination oven-steamer
With the meat probe operating
Cooking chamber capacity:
28 Steam table pans (12 x 20 x 2-1/2"), or 20
Bake pans (18 x 26"), or 40 Gastronorm pans
(1/1)
All units are supplied on stainless steel legs.
Controls and monitoring displays for cooking time, operating mode, and temperature occupy the control
panel. The upper portion of the panel has a digital time readout and touch pads for setting the time. Below
the timer section are lights to indicate the status of the unit plus touch pads that select the mode of
operation and switch on the power. A digital readout shows the chosen temperature, which is selected with
a dial. Status of the pilot burners is indicated by the lights above the pilot ignition switch, located behind the
sliding door in the front of the unit.
An insulated steam generator is mounted next to the oven. Steam enters the cooking chamber through two
connecting tubes at the top and bottom on the right side of the cavity.
The air heating space, containing the heat exchanger tubes and fans, is separated from the cooking
chamber by removable right-hand and top partitions.
The compartment containing the automatic controls and other electrical components is on the right-hand
side of the unit and is entered by removing the right outside panel or by opening the hinged panel in the
front.
A drain is located in the floor of the cooking chamber. Fluids drain from the floor to the stainless steel drain
pipe outside the oven. This drain pipe includes a spray condenser, which suppresses any steam escaping
from the chamber. The drain assembly includes a built in vent with overflow protection.
The roll-in loading and unloading equipment for Combo SuperSystem 40 consists of the Model CCS "Smart
Cart" and the separate Model CRS rack. When the rack is engaged with the cart, a hand crank raises the
rack for transportation and lowers the rack to position it in the oven. The cart is disengaged from the rack and
removed before the oven door is closed. Design of the system allows the rack to be easily held in and
transferred between reach-in or walk-in refrigerators and freezers, blast chillers, and holding cabinets.

Water Conditioning
It is desirable to supply the steamer with water that will not form scale. Scale formation depends on the hardness of
the water and the hours of operation. In a few areas of the United States, the water supply is sufficiently free of
minerals to avoid scale formation. However, most water supplies carry heavy loads of minerals, which will form scale
and possibly cause premature failure of components.
Your local water utility can provide a statement on the scale forming qualities of the water supply. Water
supplied to the boiler should contain not more than 30 parts per million total dissolved solids (TDS) and
should have a pH of 7.0 or higher.
Please follow these simple precautions:
1. Do not rely on "water treaters" commonly sold as scale preventers and scale removers. They do not
work. The only proven way to prevent scale build-up is to feed in water practically free of scale-forming
minerals.
2.
If your water supply carries scale-forming minerals, as most water supplies do, run the water through a
properly maintained softener. Exchangeable softener cartridges or a regeneratable softener can be
used. In either case, establish a regular program of exchanging the cartridges or regenerating the
softener. Installing a water meter on the inlet line between the softener and the steamer will give an
accurate check of water consumption and a way of determining when to change the cartridge or
regenerate the softener. By using a softener and operating within the softener's capacity to exchange
minerals, the user will optimize performance and minimize maintenance of the steamer.
3.
If you notice a slowing of steam production, have your authorized Groen service representative check
the unit for build-up of scale. Heavy scale will reduce the unit's ability to boil water and can cause a fire
tube in the steam generator to overheat and burn out.
TO MINIMIZE SCALE PROBLEMS, USE AND PROPERLY MAINTAIN A SOFTENER, AND CLEAN
THE STEAM GENERATOR PERIODICALLY OR AS NEEDED.

BY PERSONNEL 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.
B. Electrical Supply Connection
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. The
electrical schematic is located in the service compartment
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.
DANGER:
ELECTRICALLY GROUND THE UNIT AT THE TERMINAL PROVIDED.
FAILURE TO GROUND THE UNIT COULD RESULT IN ELECTROCUTION
AND DEATH.
1.
Panel Removal
The wiring and the control compartment are accessed by removing the right side panel. Remove
one screw at the back of the panel, then slide the panel toward the front of the unit. Set the panel
aside.
2.
Supply Voltage
The CC40-E must operate at the rated nameplate voltage ±10%.
3.
Terminal Block
The terminal block for incoming power is located at the back of the control compartment. The
ground terminal is located below the terminal block. The unit must have a separate ground wire
for safe operation. Minimum size of the ground wire is 6 AWG (4.5 mm) for a 200 Amp circuit or 8
AWG (3.5 mm) for a 100 Amp breaker.

Installation (cont'd)
C. Water Supply Connection
Two water connections are required. One supplies water to the steam generator (treated water), and the
other is for the condensate spray (untreated water). A back siphonage device (check valve) must be
installed in each incoming cold water line according to local plumbing code. The water line pressure
should be between 30 and 60 PSIG (210 and 410 kPa). A pressure regulator is required above 60 PSIG
(410 kPa). Two 3/4 inch NH (garden hose type) connectors are required to connect the water supply to
the water inlet valves. The minimum diameter of each water feed line is 1/2 inch (13 mm). Use a washer
(or, if necessary, two washers) in the hose connection. Do not allow the connection to have any leak,
regardless of how small.
D. Drain Connection
A hose may be attached to the outlet of the drain by means of a clamp. Use 3" ID hose for CC40-E. The
hose may be connected directly to an atmospherically vented building drain.
The drain has a 2 inch (5 cm) air vent, which eliminates the need for a free air gap at the connection to the
building drain, unless such a gap (Figure 4) is required by local code. Do not block the air vent in any way.
Do not attach anything to the vent tube or reduce the size of the vent tube.
Do NOT use plastic pipe in the drain line, because the drain must withstand boiling water. Install the drain
line with a constant downward pitch. Do NOT create any water trap (Figure 5) in the line.

A. Controls and Indicators
The control features routinely used by the operator are on
the right front side of the unit and are described as follows.
(Refer to Figure 7).
1. Time Section
In the Oven and Combo Modes of operation, the timer
functions only as a "cooking time minute minder" and
does not turn the unit on or off. In the Steamer Mode, the
timer controls the operation of the steaming function.
a. Display Window — Displays the operating time
remaining in the Steamer, Oven, or Combo Mode,
because the timer counts down. Format of the
display is "hours : minutes". Maximum minute
display accepted by the unit is 59. Any recipe
calling for more than 59 minutes should be
converted to hours and minutes format, e.g., 90
minutes is equal to 1 hour and 30 minutes. Display
will read 01:30.
b.
Time touch pads — used to enter time values.
c.
CLEAR — Pressing this touch pad once stops the
beeper and resets the timer to the timer that was
last set. Pressing twice clears the timer to 00:00.

3.
Prepare a warm solution of the detergent as instructed by the supplier. Wet a cloth with this
solution and wring it out. Use the moist cloth to clean the controls, control panel, and other
electrical parts that must not have liquid running freely on them.
To remove materials stuck to the unit, use plastic wool, a soft-bristle brush, or a plastic or
rubber scraper with detergent solution. Do not use any metal material (like a metal sponge)
or metal implement (like a spoon, scraper, or wire brush) that might scratch the surface.
Scratches make the surface hard to clean and provide places for bacteria to grow. Do not
use steel wool, which may leave particles imbedded in the surface and cause eventual
corrosion and pitting.
Stainless steel surfaces on the outside of the unit may be polished with a recognized
stainless steel cleaner.
D. Cleaning Inside
To automatically clean the cooking chamber and/or de-lime the steam generator, a special sequence of
operations (the Clean Cycle) has been programmed into the Convection Combo computer. To run this
automatic Clean Cycle for cooking chamber cleaning, steam generator de-liming, or both actions at the
same time, follow the instructions as outlined in the table below:
Degrease Cooking
Chamber Only
Omit Step 2
De-Lime Steam
Generator Only
Omit Step 1
Degrease Chamber and
De-Lime Generator
Perform all steps
Following the oven cleaner supplier's instructions, you must bring the oven to a temperature of 200°F (93°
C) or less. Do not begin degreasing or de-liming while the oven is above 200°F (93°C).
Close the door, put the unit into Oven Mode, and select 200°F (93°C). If the HOT light is on, use the Fast
Cool Mode to cool the oven until the HOT light goes off. If the HOT light does not come on, immediately
open the door to shut off the oven heaters. Once the HOT light is off, you can proceed safely.
When the oven has reached the desired temperature, take the unit out of Oven Mode by clearing the timer
and pressing the OVEN touch pad. Enter "99" (00:99) into the timer. The timer window will display "CC".
WARNING:

partitions to apply the oven cleaner. Remove both right side partitions only when more
complete cleaning is necessary.
Open the door, wait until the fans stop moving, and then remove the oven rack. Use a glove if
the oven is hot. The right side partitions usually do not need to be removed for cleaning; they can
just be swung open. To remove the partitions, follow in reverse order the installation procedure
described below.
21
Cleaning & Maintenance (cont'd)
WARNING:
DO NOT OPERATE THE UNIT IN ANY MODE UNLESS BOTH

Step 2. De-Liming
Hardness of the water affects how well the de-limer works. If the water is very hard, stronger
solutions of the de-limer may be needed, and de-liming may need to be done more often. Use a
properly maintained water softener. (Refer to the Water Conditioning section of this manual.)
Window will display "CC" and WAIT will be on. After beeper sounds and "CC" display begins to
flash, WAIT will turn off and READY will turn on.
Following the directions of the supplier, pour de-limer into the de-liming port located behind the
lower right side partition inside the unit (Figure 8). The capacity of the steam generator is 7 gal
(26 L). If you are using Lime-A-Way, pour in 3/4 gal (2.6 L).
NOTICE:
Do not use more than the recommended amount of de-liming
agent. Overflow of excess agent could damage the unit.
Pour 1 cup of liquid de-limer directly into the cooking chamber drain.
WARNING:
IF THERE IS OVEN CLEANER ON OR NEAR THE OVEN FLOOR
DRAIN, POUR ONLY A SMALL AMOUNT OF DE-LIMER AT FIRST, TO
MAKE SURE THERE IS NO RAPID REACTION BETWEEN THE OVEN
CLEANER AND DE-LIMER. DO NOT BREATHE ANY RESULTING FUMES.
Step 3. Degreasing and/or De-Liming
Close the oven door and press START. The display will now read "CL:45", and the colon will
blink once each second. The unit will now begin an automatic sequence that involves heating,
draining, and refilling the steam generator at various time intervals. The display will count down
each minute.
IMPORTATNT: To exit the Clean Cycle at any time, press and hold the CLEAR touch pad
for 3 seconds.
After you exit the Clean Cycle, and before you cook any food in the unit,
be sure to wash out all chemical residues thoroughly by filling and

wait about 4-5 minutes. To drain the generator, take the unit out of all
modes, or turn the unit off; then wait 10 minutes. It is strongly
recommended that the unit be run 10 minutes in Steam Mode prior to use.
Also, wipe chemical residues from the cooking chamber interior with a
wet, clean cloth before you cook in the unit. Rinse the cloth often. This
cleaning includes both sides of each of the two removable partitions, the
rack, and the walls behind the partitions. The partitions can be rinsed in a
sink.
When the Clean Cycle is complete, the display will read "00:00"
WARNING:
AVOID ALL DIRECT CONTACT WITH HOT EQUIPMENT
SURFACES. DIRECT SKIN CONTACT COULD RESULT IN SEVERE
BURNS.
Before you use the unit for cooking, wipe the whole interior with a clean, wet cloth. Rinse the
cloth often. This cleaning includes both sides of each of the two removable partitions, the rack,
and the walls behind the partitions. The partitions can be rinsed in a sink.
WARNING:
DO NOT OPERATE THE UNIT IN ANY MODE UNLESS BOTH
REMOVABLE INTERIOR PARTITIONS HAVE BEEN RETURNED TO THEIR
PROPER LOCATIONS.
If the unit will not be used right away, leave the door open long enough to let the chamber dry
completely.
