The maximum electrical power of the water heater is
550 W. The actual power consumption of the heating
element depends on the connected photovoltaic po-
wer as well as on the radiation strength provided by
the sun. The water is heated to a maximum of 65°C
to ensure scalding protection. Detailed information
can be found in the data sheet or on the nameplate.
The water heaters are equipped with a combined
check and pressure relief valve (Table 1, No. 5) to pre-
vent overpressure during appliance operation. The
water tanks are made of steel with a high-strength
enamel coating and additional cathode protection
provided by a magnesium anode.
Assembly
The water heater must be installed vertically, in a
frost-free and dry room, close to the withdrawal
point. The unit is designed for fixed wall mounting
only. Make sure that the wall has sufficient load-be-
aring capacity. When selecting a suitable installation
location for the water heater, the following must be
considered:
• Wall type and material,
• dimensions of the unit,
• mounting type,
• arrangement of the fastening elements for wall
mounting,
• arrangement of the pipes
• and the degree of protection against water
leakage.
The installation site must comply with the require-
ments of the electrical installation. During installa-
tion, provide sufficient distance to adjacent walls
and sufficient space under the unit for the water
and photovoltaic connections.
PVB-10
The hanging strip (refer to Picture 1) is fastened
securely to the wall using two dowels and the screws
supplied. After mounting the wall bracket, the hot
water tank is hung in position. The water heater
is then fixed to the wall using the third dowel and
the third screw (hexagon head screw) through the
eyelet at the bottom of the housing. A drilling hole
template is enclosed with the product.
PVB-30 and PVB-80
The fixing elements (e.g. 12mm stud bolts) must be
secured against being pulled out of the wall. The
securing elements must be designed for THREE
TIMES the weight of the water heater filled with
water. Shims are to be placed under the screw heads
of stud bolts. A drilling hole template is printed on
the product packaging.
Connection to the water suppy
When connecting the device to the water supply,
please observe the indicated arrows and rings
around the cold and hot water pipes (supply and
return pipes). The cold-water pipe features a blue
ring and is marked with an arrow pointing towards
the pipe. The hot water pipe is indicated by an arrow
pointing out of the pipe and a red ring.
The water heater is equipped with a combined check
and pressure relief valve, which is included in the
product packaging and MUST be installed on the
cold-water pipe. The arrow on the body of the valve,
which indicates the direction of water flow through
the valve, must be followed during this installation.
The pipe connectors have male G½ threads. Sche-
matic representations regarding the connection of
the water heater are shown in pictures 1 and 2.
The water heater operates by the pressure of the
water pipe. The water pressure of the water supply
system should be higher than 0.1 MPa (1 bar) and
lower than 0.5 MPa (5 bar). If the pressure of the wa-
ter pipe exceeds 0.5 MPa, a pressure reducing valve
must be installed. If additional equipment, which
is not included in the standard delivery, must be
used to comply with local regulations, they must be
installed according to these specifications.
In case the water pipes are made of copper or other
metal which differs from the metal of the water tank,
as well as if connecting elements made of brass are
used, non-metal fittings must be installed on the
supply and return side of the water heater (dielec-
tric fittings).
