Safety instructions
1. Read and strictly follow the installation and operating instructions to ensure a long
life and reliable unit operation.
2. The unit is designed to be wall mounted.
3. The unit can only be used when in perfect technical condition and correctly
assembled.
4. If there is a non-return valve installed on the water supply pipe the safety valve
must be tted between unit and non-return valve. This relates to KDE only.
5. Inlet and outlet pipes should not be made of plastic. This relates to KDE only.
6. The maximum inlet water temperature should not exceed 60°C.
7. The unit should always be vented before initial start-up. Vent the unit each time
after the water has been emptied from the heater or pipes (e.g. when water supply
system has been repaired or maintained).
8. Connection to the mains and measurement of re protection effectiveness should
be made by a qualied person.
9. Water heater must be unconditionally connected to protective grounding-the quality
of which (continuity of the protective conductor) should be checked periodically
by qualied electrician. It is recommended to install heater on grounded, steel or
copper hydraulic ttings.
10. The unit must be permanently connected to the mains which is equipped with
earth clamp.
11. According to the general norms, electrical installation must be equipped with
current-diferential switch of high sensitivity (of max rated current 30 mA), whereby
we recommend installing a separate four-pole residual current circuit breaker
(regardless of the remaining part of the installation) of current 10 or 30 mA
12. The unit must not be installed in the place which is exposed to the danger of
explosion and place in which the temperature may go down below 0°C.
13. Storage of water heater in the rooms where temperature drops below 0 degrees
may result in its damage (there is water inside the device) and may eventually
lead to the loss of warranty rights

4
14. Do not use when the water has been emptied from the unit or pipes (e.g. when
water supply system has been repaired or maintained).
15. Unit’s cover must not be taken off while power is on.
16. Failure to install the lter on water supply pipe can cause unit damage.
17 Lime scale built up on heater’s elements may limit water ow and lead to heater’s
damage. Such damages are not subjected to warranty rights. Water heater and
sanitary ttings should be periodically descaled, whereas, frequency this process
should be adjusted to water hardness in given installation. Lime scale built-up
may be partially limited by usage of magnetic descalers installed on the cold water
inlet pipe.
18. Appropriate precaution must be taken when using hot water. Temperature of water
over 40°C may cause hot feeling and can be dangerous for children, whereas,
temperature above 50°C may lead to rst degree burn (espcially amongst small
children).
19. Electronically controlled heater is a electrical surge sensitive device, therefore
the electrical installation must contain surge protection devices.
20. Water heater should be mounted in such a way in order to enbale easy access
for service and service repair. It is connected with keeping minimal distance from
the walls and the ceiling of min 100mm.

Before you supply voltage for the rst time, make sure that
you set the heater’s power at appropriate value (always
consider the capacity of your home’s electrical system).
Notice: Conguration must be performed before initial
start-up when power supply is switched off. Set
2 (two) switches at proper position to congure
a heater. The switches are located on electronic
board. Each switch has 4 (four) positions, they
are described as P(power settings) and F(other
settings). Switch on a power supply to upgrade
conguration. After you supply power to PPE2 or PPVE
a display will show: (PW...) - software version of control
panel, (MSP...) - software version of controller and the
value of rated power that has been set for the heater
(PPE2; PPVE).
P switches settings (for PPE2, KDE2, PPVE):
• 1, 2 - rated power of heater,
• 3, 4 - type of heating box,
Do not reset P switches for KDE - keep factory settings
intact.
Fswitches settings:
• 1, 2, 3 - do not change! keep factory settings
intact,
• 4 - ON - blocks access to the heater’s settings.
In this case for PPE2 or PPVE, the display shows
the desired temperature value (which has been
adjusted before the heater is off), the heating icon
and other possible working characteristics.
Weight square shows the
