use of piping with resistance to high temperature and pressure. We recommend the use of
pipe type PEX, PPR, MULTILAYER, amongst others.
b)
It is necessary to install a safety device at the cold water inlet of the appliance. The safety
device must be in compliance with the standard EN 1487:2002, maximum pressure 7 bar (0.7
MPa)
c)
Besides this device, other components will be necessary to ensure the interruption of the
hydraulic load, installed according to this sequence:
Cut-off valve
Pressure reducing valve
Safety group with discharge valve
Expansion vessel
WARNING
DANGER
The safety/discharge valve must be connected with piping whose diameter is not
less than the cold water inlet coupling.
The discharge must be connected to a sewage siphon or, if this is not possible,
elevated to a distance of at least 20 mm from the pavement to allow visual
inspection.
All the above recommendations have been made to ensure the safety of people,
animals and others.
We recommend the installation of a cut-off / section valve between the gate valve
and the hot water cylinder for the purpose of maintenance, safety or emergency.
The Manufacturer is not responsible for damage related to not following these
recommendations / warnings.
4.5.
Electric Connections
To establish the electric connection of the equipment, check these conditions:
a)
The thermodynamic equipment must be plugged to the power supply only after filling entirely
the hot water cylinder
b)
The thermodynamic solar system must be connected to a single phase voltage (230 V
AC/50Hz)
c)
The connections must comply with the local standards
d)
Earth wiring is mandatory
It’s recommended that the installation includes:
Bipolar circuit-breaker with connection cable with a section at least of 2,5 mm
Protection differential circuit breaker of 30 mA
WARNING
The safety thermostat of this thermodynamic equipment must not, under any
circumstance, undergo any repair outside the installations of the manufacturer.
Not complying with this clause invalidates the warranty of the equipment.
