SAFETY INSTRUCTIONS FOR THE INSTALLATION
Essential recommendations for safety
•
Install the appliance on level base made of non-combustible materials and of sufficient
strength to support its weight.
•
Use extreme care not to drop the boiler or cause bodily injury while lifting or mounting
the boiler onto the base. Once mounted, verify that the appliance is safely set on its
base.
•
Do not use or store any flammable or corrosive products, such as paint, solvents, salts,
chloride products and other detergent products near the appliance.
•
Make sure that the condensate outlet is never obstructed and that a condensate
neutralisation system is installed if required.
•
Make sure that all air vents are unobstructed at all times.
•
In the event of small amounts of hot water repeatedly being drawn off, a stratification
effect can develop in the tank. The upper hot water layer may then reach very high
temperatures.
•
Hot water can cause scalding! The temperature of the domestic hot water can be
adjusted up to 75 °C in the boiler. However, the temperature of the domestic hot water at
the drawing off point must comply with local regulations.
•
The risk of developing bacteria exists, including “Legionella pneumophila”, if a minimum
temperature of 60°C is not maintained in both the DHW tank and the hot water
distribution network.
•
In order to avoid exposure to extremely hot water that can cause serious burns, never
leave children, old people, disabled or handicapped people in the bath or shower alone.
Never allow young children to turn on the hot water or fill their own bath.
•
ACV recommends using a pre-set thermostatic mixing valve in order to provide hot
water at a maximum of 60°C.
Essential recommendations for the electrical safety
•
Only an approved installer is authorized to carry out the electrical connections.
•
Make sure that the appliance is connected to the earth.
•
Install a 2-way switch and a fuse or circuit breaker of the recommended rating outside
the appliance, so as to be able to shut power down when servicing the appliance or
before performing any operation on it.
•
Isolate the external electrical supply of the appliance before performing any operation
on the electrical circuit.
•
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless
supervised or unless they have been given instruction concerning the use of the
appliance by a person responsible for their safety.
Essential recommendations for the correct operation of the appliance
•
The connections (electrical, flue pipe, hydraulic) must be carried out in accordance
with local standards and regulations in force.
•
The appliance must be installed in a dry and protected area, with an ambient
temperature comprised between 0 and 45°C.
•
Install the appliance to ensure easy access at all times.
•
To avoid any risk of corrosion, connect the stainless steel DHW production tank
directly to the earth.
•
Make sure that the mains water used to fill the boiler has a minimum pressure of 1.2 bar.
•
Make sure to install a pressure reducing valve set at 4.5 bar if the mains supply
pressure is in excess of 6 bar.
•
The DHW circuit must be fitted with an approved safety group, comprised of a 7
bar safety valve, a check valve and a shut-off valve*.
•
If works need to be performed (in the boiler room or close to the air vents), make
sure to turn off the boiler to prevent dust from entering and accumulating in the
boiler heating system.
General remark
•
If the water drawing off point is far from the tank, installing an auxiliary DHW loop
can allow to get hot water more quickly at all times.
