Lemet Greenline and Ecoway can only be installed vertically. Lemet Horizontal can only be
installed horizontally with the hot water outlet and cold water inlet facing downwards
Fit all components supplied
The water heater is not suitable for outdoor installation
It is forbidden to install the heater in places with explosion hazard, in a location with acid
vapors and/or dust, or in gas-saturated environments or exposed to freezing temperatures,
causing the freezing of water in the tank, in the places where the heater must be exposed to
water vapor. In the case of the assembly, installation, and operation of the water heater in
unusual places (e.g. in the attic, indoors in rooms with floors sensitive to water, in cabinets,
etc.), it is necessary to take into account the possibility of the possible water leakage and in
connection with that, take appropriate preventive measures enabling the connection of water
and its drainage in order to prevent secondary damage
IMPORTANT:
We strongly recommend to install a
pressure reducing valve
if the water
pressure is too high (5 bar or more) or if you suffer from fluctuating water pressure. High water
pressure and/or fluctuating water pressure often occur in apartment building, flats, farms,
older houses and houses and buildings in elevated areas. Install a pressure reducing valve
where your mains water supply line enters your premises or right behind the pressure relief
valve. Ensure the water pressure is set at 3 bar. Any damage caused by a too high water
pressure or fluctuating water pressure will not be covered by the warrantee.
Pressure reducing valve
3.1 Connection to the water supply system
The heater must be connected to the mains water supply in such a way that it allows easy
disconnection for maintenance without damaging the connections and destroying the installation. The
minimum free space must be 30 cm for easy access in case you need to replace the heating element
or the anode. It is forbidden to cut the connection muffs to the water supply system, since this may
cause damage of the corrosion protection coating.
The connection of cold water is marked with a blue band, and the outflow of hot water is marked with a
red band.
The tanks may only be connected to the mains water supply whose water is compliant with
the requirements of the Council Directive 98/83/EC of 3 November 1998 on the quality of water for
human consumption and competent in the field of the national legislation.
It is forbidden to apply plastic hoses for connection, which are not adapted to temperatures higher
than 110C and pressure exceeding 1.0 Mpa. It is recommended to use flexible connection hoses
specifically designed for hot water. Always use pressure and temperature resistant pipes and
connectors.
Models: Lemet Greenline vertical/ Greenline Horizontal/ Ecoway vertical/ Small - assembly in
pressurised version
The water heater can be connected to a water supply system with the pressure not exceeding the one
determined for a given tank type in chapter TECHNICAL DATA.
In the domestic hot water installation,
it is recommended to install a diaphragm vessel for domestic water in order to minimize the effects of
the so-called "hydraulic impact" or sudden pressure surges.
