Water Drain System; Gas Connection - Electrolux 267752 Installation, Operation And Maintenance Manual

ATTENTION:
- The periodic check of fi lter functionality, according to that indicated
by the manufacturer, is important to avoid compromising appliance
operation and to prevent the risk of corrosion.
- For good operation of the water softeners and fi lters make sure
to regularly service them.
Note: The softener (Automatic Water Softener) with automatic
regeneration has a kit (Resin Sterilizer) for sterilization of the
resins (additional request).
- To prevent damaging the appliance, at every periodicregeneration
do a fi lter wash cycle without introducing water in the oven.
- The manufacturer declines any liability in case of incorrect
maintenance.
Attention:
Caution: the use of polyphosphates can cause adverse
reactions regarding the waters PH and conductivity
levels. It has also been linked to the creation of foam
that can also have adverse reactions on the water
level circuit in a boiler. Therefore, the manufacturer does not
recommend their use for scale control.
CHECK SUPPLY PRESSURE INPUT "CWI1" AND "CWI2"
The pressure measured upstream of the oven (and downstream
of any WATER FILTRATION SYSTEMS installed). Must be greater
than 150kPa (1.5bar/22psi) and need not be greater than 450kPa
(4.5bar/65psi) measured in in dynamic conditions, I.e. during a
cleaning phase.

Attention (water inlet CWI2)
If the feed pipes supplied with the appliance are not long
enough for installation, use longer ones with internal
diameter of at least ø 20 mm and without union elbows.

5.2 WATER DRAIN SYSTEM

The oven is supplied with an air-break system to prevent any
backfl ow from the drainage system from reaching the oven's
internal circuits and the cooking chamber. The presence of this
system means that the drain pipe can be connected directly to
the mains drainage system or routed to a fl oor gulley with grating.
The fl exible drainage hose or rigid pipe can be directed to the
side or rear of the appliance if the oven is not positioned against
a wall; this line must not be directed towards the front of the ap-
pliance to prevent interference with roll-in grid racks. The drainage
pipe internal diameter must be no smaller than the oven drain
outlet (1 1/4"), no longer than 3 feet (1 metre) and must resist
temperatures of up to at least 212°F (100°C). Avoid restrictions in
the case of fl exible hose pipes, do not fi t elbows on metal pipes
anywhere along the drainage line. Also avoid horizontal sections
in which water might collect (minimum gradient 5%).
WARING: BLOCKING THE DRAIN IS HAZARDOUS.

Important:
- Do not obstruct the safety outlet DO.
- Do not connect the safety outlet DO to the drainage system.
Note:
If water comes out of the AIR-BREAK (safety outlet DO) this
means the drain D is blocked. Any elimination of the obstruction
must be carried out by specialised technical personnel.

6. GAS CONNECTION

6.1 WARNINGS
• Make sure the appliance is set up for the type of gas with
which it will be supplied.
• The gas inlet connector is yellow in color.
• Before installing consult your local gas utility company to check
the compatibility between the available supply and the consumption
of the appliance.
• Before hooking up the appliance to the gas pipeline remove the
plastic protective plug from the gas connector.
• Fit a rapid gas shut-off valve and the gas regulator (supplied)
upstream from the appliance in an easily accessible position.
• On completion of installation, use soapy water to check gas
connections for leaks.
• It is not possible to adjust the combustion air ventilation
capacity.
• If the appliance is hooked up to a supply with a different gas
type with respect to the factory setting, after making the necessary
changes check that it is working correctly.
