ATTENTION
- The fuse and power socket for 3000W model should be the standard one,
with specification 16A/250V~. Wire connection must be in accordance to
national standard.
- For 5000W model, heater must be connected directly to electrical network
with 25A/250V~ fuse and 32A, 30mA RCD.
- The socket, for 3000W model and the RCD for 5000W model, should be
installed in place where humidity is less than 80%, and beside the water
heater. It is not allowed to be installed below the water heater.
- The water heater should use the independent power supply which have
the reliable earthling connections.
- Water pipes and the sewer pipes could not be used for grounding.
- There may occur some water-drops from pressure valve which are caused
by high water pressure. This is normal phenomenon. Do not stuck the
pressure-release valve outlet.
- To avoid overheating, please fill heater with water before first use.
- If power plug is damaged, please contact with the professional
maintenance service.
Installation method
FIX WATER HEATER
1. The installation must be done by professional personnel.
2. This is wall-hang electrical water heater, it must be located in a place
where it is:
- drainable and unfrozen,
- concentrated water use,
- enough space for maintenance and repair,
- the volume of water in the installation pipes should not be less than 4 times of
volume of water heater.
- no flammable gas or strongly corrosive gas are nearby,
- no strong electric magnetic field is nearby,
- no direct sunlight, rain or wind.
3. Drill 4 holes (please refer to drilling holes picture), then use a hammer to
place the bolt cap into the holes. Then fix the wall-hang board with
screw. See the pic.4.
4. Lift the water heater; move it slowly forward until the hook is in position
and lock the heater with a screw. Make sure the heater is fixed.
Note:
(1) The two plug bolt hooks should be completely in the wall and at the
same height (horizontal).
(2) For the convenience of the repair and maintenance, leave a space of
50cm at least at the left side of the water heater (the side with power supply
cable).
(3) Water heater must not be installed transversely and should not incline
after installation.

9
When drilling holes in the wall for installation purposes, take care not to
damage any electrical wiring or existing piping.
Electrocution caused by contact with live wires. Explosions, fires or asphyxiation
caused by gas leaking from damaged piping. Damage to existing installations.
Flooding caused by water leaking from damaged piping.
Perform all electrical connections using wires which have a suitable cross
section.
Fire caused by overheating due to electrical current passing through undersized
cables.
Protect all connection pipes and wires in order to prevent them from being
damaged.
Electrocution caused by contact with live wires. Flooding caused by water
leaking from damaged piping.
Use suitable manual tools and equipment (make sure in particular that the tool
is not worn out and that its handle is fixed properly); use them correctly and
make sure they do not fall from a height. Replace them once you have finished
using them.
Personal injury from the falling splinters or fragments, inhalation of dust, shocks,
cuts, pricks and abrasions. Damage to the appliance or surrounding objects
caused by falling splinters, knocks and incisions.
PIPE CONNECTION – non preassurized boiler
1. Install the multi-functional valve and water inlet valve to the water inlet of the
water heater.
2. Please refer to the picture for installation requirements and instructions how to
connect heater, water tap, valve and pipes. Ensure that water pipes are clean
and there is no blockage inside pipes. It is necessary to install water inlet
valve.
3. In the heating process there can be a few water drops come out of the safety
valve.

10
4. If the heater is not installed in the indoor place, it should be installed in the
place where it is no direct sunlight and rain. To avoid the heat losses, it has to
be installed near the place of use of water.
5. When the heater is not in use for a long period of time, please unplug the
power supply and pour the water out of heater.
6. The water tap or the connection on the outlet water pipe must be without the
valve. The installation must be done by professional personnel.
NOTE: Heater is equipped with multi-functional valve. Water inlet valve and water tap
is not included in package! You must use water tap for non preasusurized boiler! You
have to install boiler with water connections downwards!

Koristni nasveti
V evropskih državah je pri uporabi naprave potrebno upoštevati naslednje
informacije:
ODLAGANJE ODPADKOV: Tega izdelka ne odlagajte kot nesortiran komunalni
odpadek. Potrebno je ločeno zbiranje takšnih odpadkov, ki se ločeno obdelujejo.
Te naprave ne smete odložiti med gospodinjske odpadke. Za odlaganje obstajajo
različne možnosti:
A) Lokalna uprava je določila sistem zbiranja, kam se lahko odlagajo elektronski
odpadki brezplačno za uporabnika.
B) Ko kupujete nov izdelek, prodajalec vzame nazaj star izdelek brezplačno.
C) Proizvajalec vzame nazaj star aparat brezplačno za uporabnika.
D) Stari izdelki vsebujejo koristne vire in jih lahko prodate trgovcem odpadnih
materialov.
Divje odlaganje v gozdove oz. v naravo ogroža vaše zdravje, ker zdravju škodljive
snovi odtekajo v podtalnico in najdejo pot v prehrambno verigo.
