Whenever requested, it must be proved by submitting the technical report of the entity
responsible for it, or alternatively by registering them in the instruction manual in the
dedicated section.
3.12 In order to avoid damage to the equipment caused by overpressure, safety
elements such as pressure relief valves and / or thermal discharge valves, if applicable,
as well as an expansion vessel fitted to the installation, shall be ensured at the time
of installation and its correct functioning must be ensured. It should be noted that: the
valves referenced must have a value equal to or less than the pressure supported by
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 stoves, 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.
