Instantaneous water heater

INSTALLATION AND OPERATING MANUAL
The heater is ready for operaon (voltage is present) from
the moment when the power is switched ON with the circuit
breaker, which is indicated by the LED. The water is heated
only when it ows through the tank with the heaters. Great-
er power is switched gradually with increasing water intake.
Depending on the range seng and the temperature of the
water in the system, warm or hot water is discharged. Se-
lecon of the appropriate operang range can be done on
the basis of the temperature of the heater feed water. Red
LED’s indicate at what power level the heater is currently
operang - (see Table 3)
The heater has the following protecon systems installed:
• a thermal switch disconnecng the heater from the
mains in the event of excessive temperature rise
• a release valve protecng it against overpressure
Electrical installaon, which will be connected to the
heater, should be done in accordance with applicable
regulaons.
Electrical installaon specicaons:
• The heater should be connected to the electrical instal-
laon in the TN-S or TN-C-S network system in accord-
ance with PN-IEC60364-3: 2000
• Connect with 4-conductor copper cable, 300/500 VAC,
with a min cross-secon area, according to , in-
troduced into the heater through the opening in its rear
panel – the heater must be permanently connected to
the mains.
• For the types of the heater protecon, see
• Connect the L1, L2 and L3 cables to the terminal strip,
to the L1, L2 and L3 terminals, respecvely
• Connect the PE cable to the PE terminal on the rear
panel (see Fig. 4)
• We recommend to install a in the heater
supply line in order to disconnect it from the mains
• The electrical installaon must be equipped with an
with a value of
For the wiring diagram of the heater, see Fig. 3
The heater must be connected to an eecve protec-
ve circuit. Protecve terminal of the heater must be
connected to the network protecve conductor and
this connecon has to be veried.
Lack of the RCCB may result in electric shock, dam-
age to equipment and re.
• Connect the heater to the water system ghtening
the nuts to the protruding nipples of the installa-
on pipes – always install the gaskets (gasket with
strainer in the water supply line). You can connect
the heater in an alternave way – you have to ob-
tain a ‘connecon assembly’ and connect the heat-
er to the system through the cut out in the boom
of its housing, using braided hoses (see Fig. 2). Be
sure to install a shut-o valve in the system supply-
ing the water to the device
• Tighten the screws that secure the heater – between
the edge of its rear panel and the plane of suspen-
sion, a clearance of approx. 2mm should be visible
• Check the ghtness of connecons, including the
water ow, remove any leaks, then vent the heater.
3. Connect the wires to the terminal block of the safety
switch:
• Connect the electronic system to the control PCB
in the cover
4. Place the cover:
• Place the cover from the boom and then push it
onto the wall. Screw in two self-tapping screws.
Set the potenometer with the notch up. Place the
knob and push it so that it snaps into the cover
5. Switch the power ON – the green LED should light up
• Set the knob in either of the posions (I or II)
• Open the water ow. More LED’s illuminate de-
pending on the ow rate
Follow the steps below to ensure correct installaon and
operaon of the device:
1. Remove the cover:
• Remove two self-tapping screws in the upper part
of the cover and remove it by lng the upper part
forward and pulling it down. Disconnect the cable
connecng the electronic system to the control
PCB xed to the cover
2. Mount the heater on the wall:
• Install dowels – selecon of holes to the suspen-
sion and the amount of dowels (3 or 4) depends
on the installer – you can use the boom of the
cardboard box with the spacing of the connecng
and assembly holes printed on it as a template;
• Insert the power cable at the point shown in Fig. 4;
• Fasten the heater using props (Fig. 5) – screw n-
ger ght only
Before placing the cover, ensure that the water feed
pipe is latched and secured on the fastening catch.
