the equipment; there shall be no cut-off valve between the equipment and its safety
valve; provision should be made for a systematic preventive maintenance plan to
attest to the correct functioning of the said safety features; irrespective of the type of
appliance, all safety valves shall be channeled to drained sewage to prevent damage to
the dwelling by water discharges. Product Warranty does not include damages caused
by non-channeling of water discharged by said valve.
3.13 In order to avoid damage to the equipment and attached pipes by galvanic
corrosion, it is advisable to use dielectric separators in the connection of the equipment
to metal pipes whose characteristics of the materials applied to this type of corrosion.
Product Warranty does not include damages caused by non-use of such dielectric
separators.
3.14 The water or thermofluid used in the heating system (hydro toves, boilers, central
heating stoves, among others) must comply with the legal requirements in force, as
well as guarantee the following physical and chemical characteristics: absence of solid
particles in suspension; low level of conductivity; residual hardness of 5 to 7 degrees;
neutral pH, close to 7; low concentration of chlorides and iron; and absence of air inlets
by depression or others. In case the installation enhances automatic water make-up, it
should consider upstream a preventive treatment system composed of filtration,
decalcification and preventive dosing of polyphosphates (scale and corrosion), as well
as a degassing step, if necessary. If in any circumstance any of these indicators show
values that are not recommended, the Warranty will cease to have effect. It is also
compulsory to place a non-return valve between the automatic filling valve and the
mains water supply, and that said supply always has constant pressure, even with a
lack of electricity, not depending on lift pumps, autoclaves, or others.
3.15 Except as expressly provided by law, a waranty intervention does not renew the
warranty period of the Product. The rights arising from the Warranty are not
transferable to the purchaser of the Product.
3.16 The equipment must be installed in accessible places and without risk to the
