Operation Manual

The wires adequate for connection to the electric system are the following:
Adequate type: H0 5VVF
H0 5RRF
Connection with wire protection tube is not allowed.
4. The connection wire and the wire with green/yellow colour mark have to be connected in the terminal
block. The plastic wire driver marked with a label located at the lower part of the cover of the fitting house has
to be broken out. (“Break out for connection”) The overhang part of the rubber wire driver, which is placed in
the bag attached to the appliance, has to be cut, then the wire driver has to be stitched to the electric system
wire. The connection wire has to be connected in the terminal block of the left side according to phase label (L,
N, ). The wire fixing and the bent clamp have to be tightened finally, then the wire driving rubber has to be
fitted to the lower horizontal surface of the cover frame in a way that it has to protect electric parts against any
possible water inflow, after mounting the cover.
Figure 7.4.-1. shows the electric connection diagram of the hot water tank, which can also bee seen on the
cover of the fitting house.
Figure 7.4.-1.
IT IS FORBIDDEN TO OPERATE THE HOT WATER TANK WITHOUT ANY PROTECTIVE EARTHING.
The protective earthing has to comply with the instructions of the Hungarian Standard MSZ 2364.
7.5. First start up
Before first start up of the appliance, please, check the following elements:
⋅ Adequate installation of the appliance;
⋅ Adequate connection of water pipes and electric wires;
⋅ The leaking of cooling pipe has been tested;
⋅ Efficient water discharge pipe.
⋅ Full insulation protection;
⋅ Adequate earthing;
⋅ Adequate power source;
⋅ No obstacle to air inlet and air outlet;
⋅ There is no air in the water pipeline and all the valves are in open position;
⋅ Efficient electric leak protection is operating;
⋅ Water inlet pressure is sufficient(≥0,15MPa)
After being connected to the water pipeline system and the electric power system, the hot water tank has
to be filled up with water from the household water supply system. The tank must be filled up with water
before switching on the heating. During filling the tank up with water, open the hot water valve of the closet
tap while keep all the other valves closed. Then open the closing valve mounted in the cold water pipe (Figure
7.3-1., item No. 1. ). The tank is filled up when water appears on the tap. For flushing purposes, the water must
be flown for some minutes, then you can close the valve of the hot water.
PLEASE TURN TO A TECHNICIAN TO CHECK THE FIRST HEATING.
Perform an eye check to decide whether connections of edges and pipe fittings are leaking or not – and
tighten them carefully, if necessary. The appliance can be connected to the electric power system only after this
check. In order to switch the heat pump of the water heater in a mode, press the ON/OFF key located on the
control panel. Before setting the clock and other parameters or programs, please follow the instructions of
chapter 4.
