Branch Circuit Protection
Groen strongly recommends that each
Convection Combo™ have its own branch
circuit protection. A double stacked unit should
have separate protection for the upper and
lower steamer-ovens.

Each current-carrying conductor must have
overcurrent protection. Refer to the label on
the back of the unit for proper wire size and
type. Watertight connections are required.
3. Water Supply Connection
A check valve (back siphonage device) must be
installed in the incoming
cold
water line in keeping
with local plumbing codes. Water line pressure
should be between 30 and 60 PSI (210 and 410
kPa). A pressure regulator is required above 60
PSI (410 kPa).
A ¾ inch (19 mm) NH (garden hose type)
connector is required to connect the water supply
to the water inlet valve. The water feed line
diameter may not be less that ½ inch (13 mm).
Use a washer (or if necessary, two washers) in the
hose connection. Do not allow the connection to
have any leak, no matter how small.
If your CC10-E is equipped with the optional split
water supply, the supply for
each
steam generator
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 gallons per minute (0.2 liters per
minute). Condensate spray water rate is 0.34
gallons per minute (1.3 liters per minute) at 30 PSI
(210 kPa).
4. Drain Connection
a.
CC10-E Without Drain Tank
(tabletop model)
A 1½ inch (4 cm) hose may be attached to the
provided drain elbow with a clamp. Do
not
use
plastic pipe. The drain must withstand boiling
water.
WARNING
:
DO NOT CONNECT THE DRAIN DIRECTLY TO A
BUILDING DRAIN.
There must be a free air gap between the end
of the hose and the building drain. The free air
gap should be as close as possible to the 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 PLASTIC PIPE. DRAIN MUST BE
RATED FOR BOILING WATER.
WARNING
BLOCKING THE DRAIN IS HAZARDOUS.
Install the drain line with a constant downward
pitch.
IMPORTANT: 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.
NOTE:
Improper drain connection will void the warranty.
b.
CC10-E With Drain Tank
A 1½ inch (4 cm) ID hose may be attached to
the supplied drain elbow with a clamp. The
hose may be connected directly to a building
drain since the drain tank has an air vent, which
eliminates the need for a free air gap at the
building drain. Do not block the air vent in any
way. Do not attach anything to the vent tube or
reduce its size.
Do NOT use plastic pipe in the drain line,
because the drain must withstand boiling water.
