• Putting the storage tank under greater pressure than 0.6 MPa is dangerous and
forbidden. If the network pressure exceeds 0.6 MPa even intermittently, a
pressure reducing valve must be installed before the hot water storage tank.
• It is forbidden to install a water supply assembly between the safety valve and the
appliance. The valve drain joint must be pointing downwards so water can drip
from the overflow pipe of the pressure relief device. This pipe must be left open
to the air. The drain pipe must be positioned to a frost-free area, away from the
appliance, and it must be left open to the air. The hidden positioning of water
dripping is forbidden.
• The pressure reduction valve and safety valve may only be installed and operated
in a frost-free environment.
• It is forbidden to operate the water heater without a protective earth.
• The storage tank may only be connected to the electricity supply with a permanent
connector. It is forbidden to use a wall plug.
• Mains network electricity may only be connected to the storage tank through a
double-pole switch where the distance between the open contacts is at least 3
mm. This separation device must be built in to the fixed power supply network.
• If the mains network connecting cabling is damaged in any way, in order to rule
out danger it may be replaced only by the manufacturer, service centre
technicians or similarly qualified experts.
• Have the first heating cycle checked by an expert.
• Only a qualified expert may remove the electric cover plate. Failure to follow this
instruction can result in an electric shock or other hazard.
• In order to guarantee safe operation, it is advised to occasionally (approximately
annually) have the correct operation of the appliance and combined safety valve
checked by an expert. In addition, we recommend that every two months the
safety valve vent button should be turned in the direction of the arrow in order to
vent the valve. By doing this it is possible to clean the valves from any possible
accretions (limescale, sand particles etc.).
