Ariston BLU1 R ABS 50 V [36/44] Additional safety rules
2.2. Hydraulic connection
Attention! Installation of safety valve Included In the delivery set Is necessary.
Do not install any stop valve between the safety valve and cold water inlet of the water heater and do not block
the drain hole of the safety valve.
Demountable connectors should be used for the water heater connection to the water supply system.
Standard connection
2.2.1.
Safety valve (A in Fig. 2) supplied must be installed on the cold water inlet of the water heater (marked with the blue ring).
2.2.2. Connect the inlet of the safety valve to the cold water line with a tube or exible hose.
2.2.3. Connect a tube or exible hose to the hot water outlet of the water heater (marked with the red ring) for hot water
removal to the draw-o point.
2.2.4. For easy maintenance, it is recommended to install a T-piece with shut-o (B in Fig. 2) between the cold water inlet and
safety valve of the water heater.
It will help to drain water from the water heater without safety valve removal.
2.2.5. To facilitate the access of air into the tank when draining water, it is recommended to install an additional T-piece with
shut-o valve at the hot water output.
2.2.6. When water pressure exceeds 5 bar, place before the safety valve a reducer to reduce the pressure.
2.2.7. The device cannot work with water where hardness is less than 12°F. If water is with hardness above 25°F,
it is necessary to use softener to reduce the formation of scale and the probability of failure of the heating element.
The water hardness should not fall below 15°F.
Connection to open tank lled with water
2.2.8.
Water is supplied to the water heater from the tank by gravity. Safety valve is not necessary in this type of connection.
2.3 Electrical connection
Attention! Electrical wiring should be done by a qualied technician, ensuring it complies with safety rules. The manufacturer is
not to be held responsiable for any damage caused by the incorrect earthing of system or for fault defaults of electricity supply.
2.3.1. If the product is already equipped with a cable and plug, simply connect it to a power supply source.
2.3.2. If the water heater is supplied without a power supply cable, use a cable featuring the same characteristics (type
H05VV-F 3x1,5 mm
2
,
Ø
8,5 mm) for connection. Remove the cover. The power supply cable should be threaded through the
relevant hole on the cover of the appliance and xed to the thermostat terminals. Then every wire should be xed in place
by the corresponding screw.
2.3.3. The water heater must be earthed. Grounding scheme should ensure the absence of electric potential on the body
of the water heater. The earth cable (of yellow-green color) should be xed to the terminal marked by the symbol
.
Fix the power supply cable using the cable clamps.
Make sure that the power supply voltage conforms to the water heater technical characteristics indicated on
the data plate.
2.2. Hydraulic connection
Note! Installation of safety valve included in the delivery set is necessary.
Do not install any stop valve between the safety valve and the inlet of the tank and do not block the drain hole of the
safety valve.
Demountable connectors should be used for the water heater connection to the water supply system.
Standard connection (Fig. 1)
2.2.1. Safety valve supplied must be installed on the cold water inlet of the water heater (marked with the blue ring). It is
recommended to turn the safety valve no more than 3−4 turns, providing sealing with water-proof sealing material.

2.2.7. Water is supplied to the water heater from the tank by gravity. For this purpose, the tank water outlet T-piece
supplying water to the heater and other places must be installed higher than the water heater top. Safety valve is not
necessary in this type of connection.
