effective regulations and specifications after finishing installation of the
appliance. In both cases, the company performing installation has to execute
safety and operation checks on the entire system.
Running hot water with temperature above 50 °C may cause serious burn
marks. The maximum water temperature displayed on the indicator is 60 °C,
which value can be actually higher than that in case of defective operation.
Children, disabled persons and elder persons are highly exposed to burn marks.
It is therefore recommended to connect a thermostatic mixing valve to the water
outlet pipe of the appliance.
The cover of the electric heating can be removed only by a technician;
failure to this warning may cause electric shock or other danger.
The maintenance operations explained below can only be performed when the
appliance is not operating, so it is switched off and the external switch is set into
“OFF” position.
The tank must be filled up with water before switching on the heating. Please
turn to a technician to check the first heating. Improper installation may cause
personal injuries or injuries in animals or damage to objects. The manufacturer
shall undertake no responsibility for these injuries or damages.
Please follow the general warnings and safety precautions listed in the previous
chapter and please comply with them strictly.
If the appliance is operated without any feet fixing, it might turn upside down. In
this case, the manufacturer shall not be liable to any damages emerged.
It is at the risk of death and therefore it is forbidden to put the water tank and
the heat exchanger under pressure larger than the permitted operation pressure
(0,7MPa)!
If the pipeline system pressure exceeds the value of 0.6 MPa
– only in a
temporary way -, a pressure reduction valve has to be mounted in front of the
hot water tank, at the location of item.
It is forbidden to build water pipeline fitting between the valve and the appliance.
It is forbidden to close the drainage pipe branch or to drivert water leakage in
non-visable way.
It is forrbiden to operate the hot water heat pump and water heater without any
protective earthing
Before repair or maintenance, the appliance always must be switched off and the
external switch must be turned into “OFF” position.
In order to ensure safe operation, it is rational to turn to a plumber to check the
appliance and the correct operation of the combined safety valve every now and
then (in every year).
Furthermore, it is recommended to blow off the valve every
month or every second month through turning the blow off button of the safety
valve in the direction indicated by the arrow. This way, the valve seat is cleaned
from any possible pollution (sand grains, scale, etc.)
It is forbidden to connect the appliance with a hose pipe.
Galvanized steel pipe,
plastic pipe and red copper pipe can equally be used as cold water pipe or hot
