4.2 POSITIONING
Place the oven under a suction hood to make sure all vapours and products of combustion are extracted.
Install the oven horizontally and check the correct positioning by means of a level; rotate levelling feet to adjust.
The oven may be installed on its own or in a group of several elements; but make sure it is not placed next to combustible
objects.
- Never obstruct the air vents and heat dissipation openings of the oven.
- The electric cable must never be subject to traction.
- Provide clearance of 1/2 metre on the right of the oven for maintenance.
4.3 COLD WATER CONNECTION
(SOFTENED)
Water pressure: min. 50 kPa max. 400 kPa (0.5 <PH
2
O < 4 bar).
The water inlets must be connected to the softened supply
network at a maximum temperature of 50°C by means of
shut-off valves, to be closed when the oven
is not being used or for maintenance work.
The water is used to condense the vapours in the
waste water outlet, to supply the humidifier and
to generate steam; between the shut-off valve and
the oven connection pipe, there must be a mechanical
filter so as to prevent any ferrous waste getting
inside that could over time cause oxidation of the
oven.
If the hardness of the water is greater than 5-7°Fr, it is
necessary to install a softener with automatic
regeneration, to be positioned after the mechanical filter.
As regards the flow rate per hour of the softener, refer to the Table on page 4.
The oven is equipped with a water pressure regulator: once the oven has been started, turn it onto the steam function and
check the following pressure on the pressure gauge located near the solenoid valve.
FGMD67 0.4 bar
FGMD107 0.75 bar
FGMD207 1 bar
If the pressure does not correspond to the figure given here, release the control knob by pulling it, turn it onto the desired
pressure and then press it to lock it.
4.4 WASTE WATER OUTLET
The water outlet “1” must lead
to an open siphon “2” so as
to allow no contact between the outlet pipe
of the oven and the collecting siphon
as per the current local health regulations
and for the oven to work properly.
To prevent bad smells and waste water getting
back into the oven, after the open siphon there
should be a normal siphon “3”.
The drain pipe is to be manufactured
with materials able to withstand temperatures
of 100°C.
N.B. ”Closed” connection to the channel is NOT allowed!
