Equi p ment D escr i p ti o n
Your Groen Convection Combo™ has a stainless
steel cooking ch amber , a n a ir hea ting compa rtment
with electri c hea ting elements an d fan, a steam
generator with electric h eat ing elements, an d a
control compartment which houses other electrical
component s.
All m ajor compon ents of the Conv ection Combo™
are encased in a 16 gauge stainless st eel ca binet.
Glass fiber insulation, lines the cabinet at a thickness
of 1½ to 2 i nch es (4 to 5 cm ). A remov able drip tray
is locat ed benea th the door.
Door hinges are reversible so that doors ma y open
from t he left or r ight side. Operator controls are
located on the ri ght side of th e front panel.
Standard cont rols l et you to opera te the Con vection
Combo in a ny one of three cooking modes:
1. As a conv ection oven
2. As a self-contained, pressureless steamer
3. As a combination oven-steamer
Models CC10- E an d C C 20-E differ in cooking
chamber size and capacity:
CC10-E: 4 steam t able pans (12x20x2½”), or
7 half- size (13x18" ) U S bak ing pans
CC20-E: 10 steam t able pans (12x20x2½”), or
9 ful l-si ze (18x26") US baking pan s
The smaller Conv ection Combo™ is ava ilable as a
table- top unit (the single CC10-E ). These units a re
also supplied on a stain less steel stand as models
CC10-EF an d (2)CC 10-EF. The larger Con vection
Combo™ is alw a y s supplied with a stand as the
single CC20-EF or the double-stacked (2)CC 20-EF.
The Convection Combo™ Fam ily: 1. Model (2)CC20-EF (Full- sized double-stacked uni t on rigi d stand),

Insp ecti o n an d U n p acki n g
OM-CC-E
Your Convection Combo™ will be completely
assembled in a hea vy shipping car ton or w ooden
crate, and attach ed to a skid. On receipt, inspect
the carton or crate carefully for exter ior damage.
CAUTION
SHIPPING ST RAPS ARE UNDER TENS ION AND
CAN SN AP BA CK WHEN CUT.
Carefully cut the straps around the carton and detach
the sides of the carton from the skid. Pull the carton
up off the unit. Be careful to avoid personal injury or
equipm e nt d amage from staples which might be left in
the carton w alls.
Water Conditioning
It is essential to supply the steam generator with
water that will n ot form scale. Even though the
steam gen erator is engineered to minimize sca le
formati on, scal e development depends on the
hardness of your water and the number of hours you
operate t he equ ipmen t.
In some areas, water is low enough in mi ner al
content to avoid scale formation. But most water
supplies are full of minera ls which form scale. It is
this scale which could lead to an early component
failure.
Your water utility can tell you about the minerals in
your wa ter. The water going to the steam gen era tor
should h a v e between 30 and 40 parts per million
(ppm) total dissol ved solids (TDS) a nd sh ould ha ve a
pH (acidity rating) of 7. 0 to 9.0. Please follow t hese
simple precautions:
Do not rel y on unproven water treat m ents
1.
which a re sold for scale prevention or scale
removal. They don’t always work. The best
way to preven t scale is to supply the purest
possible water (30 - 40 ppm TD S).
Write down the model number, serial number and
installation date and keep this information for future
reference. Space for these entries is provided at the
top of the Ser vice Log in the back of this manual.
CAUTION
THI S UNIT IS VERY HEAVY. YOU SHOULD GET
HELP AS NEEDED TO LIFT THIS WEIGHT
SAFELY.
When starting installation, lift the unit stra ight up off
the skid. Check pa cking materials to make sure
loose part s ar e not discarded w ith the material.
softener will provide longer generator life, higher
steam capacity, and reduce maintenance
requirements.
If you notice a slowdown in steam pr oduction,
3.
hav e the un it checked for scale build-up. H eav y
scale reduces the unit’s ability to boil water, and
can even cause hea ting elements in the steam
generator to overheat an d burn ou t.
MINIMIZE SCALE PROBLEMS, BY USING AND
MA INTAINING A SOFTENER , AND BY CLEANING
THE STEAM GENERATOR REGULARLY.
Groen Con vection C om bo™ ovens are also ava ilable
with an option for two separate water conn ections —
one for the stea m gener ator (soft water ), the other
for the spra y condenser (untreated wa ter). The
steam gen erator only uses 14 to 31% of a
combination oven’s water.
Since softener systems are typically sized by total
GPH (gallons per hour), the second connection could
reduce tr eat m ent requirements by u p to 80%,
resulting in significant sa v in gs.
2. If your water contains scale-forming minerals, as
most wa ter does, use a well -ma inta ined water
soften er. Wh ether an ex changeable soft ener
cartridge or a regener ating system is chosen, a
regular exchange schedule is essential.
Insta llin g a wa ter meter between the softener and
the steamer will provide an a ccurate gauge of water
use, and will help determine when to exchange
cartr idges or regenera te the softener. Using a water

If you wish t o install a Con vection C om bo™ on
top of a nother, you shoul d obta in a double
stacked un it fr om the factory.
If the unit does not have a factory-installed stand,
the install er must pr ovide a table, stan d or
counter w hich is strong enough to support th e
unit. Use of casters is not recommended.
To avoid drainage problems, level the unit fron t

Bolt the unit to the table, stand or coun ter top,
using the mounting holes in its base.
2. Electrical Supply Connections
Panel Removal
a.
The right si de panel must be removed to gain
access to the w iring and control
compartment. Remove the two screws at
the bott om of t he panel . Slide the panel
toward the front of the unit, lift it and set it
aside.

This assembly is black, blue and red. Refer
to t he labels located below the mot or and

3. Water Supply Connection
A check val ve (back siph onage devi ce) mu st be
installed in th e incoming cold water line in keeping
with local plum bing codes. Wat er li ne pressur e
should be between 30 and 60 PSI ( 210 and 410
kPa). A pressure regulator is requir ed above 60
PSI (410 kPa).
A ¾ inch (19 mm) N H (gar den hose ty pe)
connector is required t o connect t he water supply
to t he wat er inlet valve. The w ater feed line
diameter ma y not be less that ½ inch (13 mm) .
Use a washer (or if necessary, tw o washers) in the
hose connection. Do not allow the connection to
have any leak, no matter how small.
A 1½ inch (4 cm) hose ma y be attached to the
provided dr ain elbow wit h a cla m p. Do not use
plastic pipe. The drain must withstand boiling
water.
WARNING:
DO NO T C O NNECT THE DRAIN DI RE CT LY TO A
BUILDING DRAIN.
There mu st be a free air gap between the end
of th e hose and t he building drain. The free air
gap shou ld be as close as possible t o th e unit’s
drain. There must also be no other elbows or
other restrictions between the unit drain and the
two inch free air gap.
CAUTION
DO NOT USE PL AST IC PIPE. DRAIN MUST BE
RATED FOR BOILING WATER.
WARNING
BLOCKING THE DRAIN IS HAZARDOUS.
Install the drain line with a constant downward
pitch.
IMPORTA NT: Do not allow any water traps in the
li ne. A trap can cause pressure to build up inside
the cavi ty during st eam ing, which will make the
door gasket leak.
NOTE: Improper drain connection will void the w a r ra n ty .
b. CC10-E With Drain Tank
A 1½ inch (4 cm) ID hose may be atta ched to
the supplied dr ain elbow wit h a cla m p. The
hose may be connected directly to a building
drain since the drain tank has an air vent, which
elim inates th e need for a fr ee air gap at the
building drain. Do not block the air vent in any
way. Do not attach anything to the vent tu be or
reduce it s size .
Do NO T use plastic pipe i n the drain line,
because the drain must withstand boiling w a ter.
If you r CC10-E is equipped with the optional split
water su pply, the supply for each steam gen era tor
must be able to fill the generator with 1½ gallons
(5.7 liters) or water in 1½ minutes. The make-up
water rate is 0.06 gall ons per min ute (0.2 lit ers per
minute). Condensate spray water rate is 0.34
gallons per minute (1.3 l iters per minute) at 30 PSI
(210 kPa).
