3 LOCATION
It is recommendable to install the extractor hood to expel fumes to the exterior
(see fig 7)
On the left-hand side, there must be a minimum space of 50 cm between the oven and
the next appliance HVG. (see fig 8)
Likewise, the over must not be affected by the steam or heat from other appliances. The
rear panel must be in place at all times.

4 INSTALLATION
Before proceeding to install the equipment, make sure that the type of gas set for the
oven coincides with the gas supplied in the distribution network.
4.1 Electrical Connection.
−The mains voltage must be the one indicated on the characteristics plate.
−REMOVE THE LEFT-HAND SIDE PANEL in HVG models.
−EXTRACT CONTROL PANEL in HCG models
−Use a polychloroprene cable or another with the same characteristics (HO5RN-F).
−Place a general switch independent of the appliance in the mains outlet with a
distance between contacts equal to or greater than 3 mm.
−A differential grounding shunt device must be installed.
−The appliance must be connected to ground.
−Access the electrical connections strip and fix the cable to the stuffing box, C (see ).
−When installing a number of appliances in a line, these must be connected together to
ground.
4.2 Water inlet.
−Only connect drinking water to the appliance.
−Make the connection to the water mains at point A (see . ), using the hose supplied.
−The water inlet pressure must be between 0.5 and 8 Kg/cm².
−Install a filter and stop cock at the water inlet.
−For water with a hardness of over 10ºF, a water softening unit is required..
−Conductivity of the water 50-2000µS, lower conductivity optional.
Minimum concentration of chlorides Cl under 150 mg./litres.
N the case of values of over 2000µS or when exceeding the limit value for chloride,
place a hydrogen ion exchanger (see fig 9)
−Redox potential 300 mV, (alternatively chlorine content (CL2) lower than 0,1
mg/litre).
In the case of values of over 300 mV Redox potential, place an activated carbon filter
(observe the filter maintenance intervals)
Sedimentation filter Un (0,08 mm) when the impurities in drinking water are high.
