ECO
To assemble the couplings of the hydraulic circuit you must:
a) Connect the water inlet and outlet of the equipment with a pipe and fittings that can cope with
constant temperature / pressure of 75 ºC / 7 bar. For this reason, we recommend the use of
piping with resistance to high temperature and pressure. We recommend the use of pipe type
PEX, PPR, MULTICAMADA, 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:
•
Retainer valve / gate valve
•
Pressure throttle valve (in case the cold water inlet pressure exceeds 4.5 bar)
•
Safety valve / discharge valve
•
Expansion tank
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.
WARNING
We recommend the installation of a shut-off / section valve between the gate valve
and the coupling to the storage water heater for the purpose of maintenance, safety
or emergency.
The manufacturer is not responsible for damage related to not following these
recommendations / warnings.
4.6 Electrical 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 fill- ing the
storage water heater;
b) b)
The thermodynamic equipment must be connected to a monophase voltage (230
VAC/50Hz or 60Hz* (version of the equipment produced only by specific request);
c) The connections must comply with the standards of installation in effect in the territory or
country where the thermodynamic equipment has been installed;
d) Earth wiring is obligatory.
It’s recommended that the installation includes:
•
Bipolar circuit-breaker with connection cable with section equal to or exceeding 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.
