Safety Devices - Idromatic ASTRA EVO Instruction Manual

• Do not pull the steam hoses with excessive force or keep it
coiled around itself during use.
• If during operation
reasons, turn off the machine (OFF).
• If the technical data indicates a sound pressure exceeding
80 dB (A) wear protective goggles.
• If the item technical data has shown a hand-arm vibration
value greater than or equal to 2.5 mm2 make some stops
during use.
Electrical connection
•
The electrical connection of the appliance must be done by
an electrician and conform to IEC 60346-1.
•
Before connecting the appliance make sure that the data
on the label correspond to those of the mains and that the
socket is protected by a differential circuit breaker (RCCB),
with intervention sensitivity 0.03 A - 30ms.
•
In cases of incompatibility between the socket and the
appliance plug, have the socket replaced with a suitable
type by a qualified professional.
•
Do not use the device in case of temperature below 0 ° C,
if it is equipped with cable PVC (H VV-F).
•
WARNING: Extension not adequate may be dangerous or
create situations of overload of the unit.
•
The transitional insertion of the appliance may cause a
temporary decrease in voltage.
•
To prevent damage to other equipment the line
impedance must be less than 0.15 Ohm.
•
Ensure that the cable for connection to the network or the
extension cable is not damaged passing over, crushing
them, casting or the like. Protect the cable from heat and
from contact with oil or sharp edges.
•
We recommend using a cable roll, which ensure that they
are taken at least 60mm above the floor.
•
If you use an extension cord, the plug and the socket must
be waterproof and the cable must have the dimensions
shown in the table below.

In case of electrical power through inverter system (12Vdc-
230Vac) make sure that this system is sine wave and that
the power of the inverter is at least 3 kW. Use inverter
systems recommended by the manufacturer
the power supply fails, for safety

Water connection
• We recommend the use of demineralized water.
• Do not use pure distilled water or treatment of it that
can altering and diminishing the conductivity. The lack of
conductivity of the water can affect the correct
operation of the appliance.
•
In case of excessive water hardness is recommended to
use filter crystals polyphosphates additional (optional) is
fitted above the water filter. (Figure 17)
The appliance can be connected directly to the
mains drinking water supply only if in the supply
line is installed a back-flow prevention device
complying with current regulations.
The water that has passed through the back-flow
preventer device is considered non-potable.

Safety devices

• Boiler Safety valve. It protects the circuit from over-
pressures that can damage internal components of the
machine. It is recommended to replace it every 2 years
from the date of commissioning by qualified personnel.
• Safety lever on trigger-gun. It does not serve to lock
during operation under pressure but to prevent
accidental opening. Whenever you stop using the
machine it is important to operate the safety lever to
prevent opening (or drives) unwanted or accidental.
• Thermal protections of the boiler. Thermal protection
with automatic reset occurs when there's overheating
inside the heat exchanger. Thermal protection with
manual reset occurs on the occurrence of overheating of
the steam output. In case of intervention the machine in
block state with the fan forced to run for cooling down
the boiler.
• Boiler with double water probe sensor. It prevents the
lack of water in the boiler by acting upon the occurrence
of inconsistency of the probe sensors signals.
• Chamber of water level in the boiler. It prevents sudden
drops of boiler water level maintaining a constant output
flow of steam.
• Flame failure detection system by photocell. It prevents
the accidental ignition of diesel inside the boiler or
irregularities of flame during normal operation of the
machine.
