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 fitted 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 70°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 fire protection effectiveness should 

be made by a qualified person.

9.  The unit has to be earthed.

10.  The unit must be permanently connected to the mains which is equipped with 

earth clamp.

11.  Electric installation should be equipped with residual current protective devices 

and other solutions which will ensure disconnecting the heater from the source 

of power (intervals between all their poles should not be less than 3 mm).

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.  The unit must be kept in a place in which the temperature never go down below 

0°C (there is a water inside the unit).

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 filter on water supply pipe can cause unit damage.

17  Accumulation of limescale in parts of the water heater may cause limited water 

flow and failure of the water heater. Failure of the heater and damages caused 

by the limescale will not be covered by the warranty. The water heaters and 

fittings must be descaled on the regular basis, the frequency of limescale removal 

depanding on the quality of water.

18.  Appropriate precaution  must be taken while using hot water. Temperature of 

water over 40°C may cause hot feeling and can be dangerous for children.

Before you supply voltage for the first time, make sure that 

you set the heater’s power at appropriate value (always 

consider the capacity of your home’s electrical system). 

Notice:  Configuration  must  be  performed  before  initial  

start-up when power supply is switched off. Set 2 (two) 

switches  at  proper  position  to  configure  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 

configuration. 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
