Electrical Supply Connection
For a single oven, or for each oven in a double
stacked unit, provide 115 VAC, 60 Hz, single
phase, 15 AMP service. 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 this manual.
Maximum load per oven is 5½ AMPs.
In
Canada
provide electrical service in accordance
with the Canadian Electrical Code, CSA C22.1
Part 1, and/or local codes.
4.
Water Supply Connection
A check valve (anti-siphonage device) must be
installed in the incoming
cold
water lines 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 connector is required to
connect each 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 connections to have any leaks,
no matter how small.
Minimum flow rate for water delivery is 1.5
gallons per minute. Below this rate your Combo
oven will not operate. Condensate spray rate at
30 PSI is 0.34 gallons per minute for CC10-G
units, and 0.7 gallons per minute for the
C/2-20G. Double stacked units require double
the rates. To convert a steamer or combination
oven to a single water connection, order single
cold water adapter (part # 138473).
5.
Drain Connection
a.
Unit Without Drain Tank
(See figures on page 10)
A 1½ inch (4 cm) ID (CC10-G) or 2 inch (5
cm) ID hose (C/2-20G) may be attached to
the supplied drain outlet with a clamp. Do
not
use plastic pipe, because the drain must
withstand very hot water.
WARNING
:
DO NOT CONNECT THE OVEN 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 free air gap.
CAUTION
DO NOT USE PLASTIC PIPE. DRAIN MUST BE
RATED FOR VERY HOT WATER.
WARNING
BLOCKING THE DRAIN IS HAZARDOUS.
On a double stacked unit, there must be a
minimum of two inches free air gap on
each
drain, as close to each oven as possible.
Double stacked units may only share a
common drain hose downstream of
both
free air gaps.
Install the drain line with a constant
downward pitch. This is especially important
for double-stack units. The bottom unit is
conceptually shown below.
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.
Units With Drain Tank
(See figures on page 10)
A hose may be attached to the supplied
drain elbow with a clamp. Use 1½ inch ID
hose for CC10-G or 2" ID hose for C/2-20G.
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 very hot
water.
