USER MANUAL KDE3-09 KOSPEL

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 mounted only on the at wall.

3. The water heater is designed to heat DHW in households, sanitary facilities,

laboratories and workshops etc.

4. The unit can only be used when in perfect technical condition and correctly

5. 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.

6. Inlet and outlet pipes should not be made of plastic.

7. The maximum inlet water temperature should not exceed 60°C.

8. 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).

9. Connection to the mains and measurement of re protection effectiveness should

be made by a qualied person.

10. Water heater must be unconditionally connected to protective grounding- the quality

of which (continuity of the protective conductor) should be checked periodically by qualied electrician. It is recommended to install heater on grounded, steel or copper hydraulic ttings.

11. According to the general norms, electrical installation must be equipped with

current differential 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. 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).

13. 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. Safety instructionsDE;EN;FR;IL -099C_f.1290

14. 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.

15. 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).

16. Unit’s cover must not be taken off while power is on.

17. Failure to install the lter on water supply pipe can cause unit damage.

18. 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.

19. 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).

20. Electronically controlled heater is a electrical surge sensitive device, therefore the

electrical installation must contain surge protection devices.

21. 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. 100 mm.14 Installation - assembly

8. Open the cold water valve and check for

10. During heater’s installation, check the

activation of safety switch (only applies to the rst connection of the device).

11. Put the unit’s cover back.

12. Make sure that there is no access to live parts

through the holes at the back plate.

Attention! In the event of a safety switch being triggered during operation, please contact the service. Switching on the safety switch again and continuing to use the device may cause danger and serious damage to the heater.

Venting Conguration 1. Shut off electric supplies to the heater.2. Turn the ow on (turn the hot water tap on) in order to vent the water installation (for about 15-30 seconds), until the ow of water becomes constant and even.3. Switch on the electric supplies.Heating box size 15 kWHeating box size 24 kWHeating box size 27 kW

White square shows the switch position. Notice! Conguration must be performed before initial start-up when power supply is switched off. Set 2 (two) switches at proper position to congure a heater. The switches are located on electronic board. Each switch has 4 (four) positions, they are described as (power settings) and (other settings). Switch on a power supply to upgrade conguration. After you supply power to KDE5 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.switches settings:

• 1, 2 - rated power of heater,• 3, 4 - type of heating box,switches settings

• 1, 2, 3 - do not change! keep factory settings,• 4 - ON - blocks access to the heater’s settings. In this case in KDE 5, the display shows the desired temperature value (which has been adjusted before the heater is off), the heating icon and other possible working characteristics.The heater is factory set at NORMAL mode (30-60ºC). To use the heater for shower purposes it has to be changed to SHOWER mode (30-55ºC). Change of the modes can only be done by authorised service. EN16 heating operation is turned off, or if more than 50 seconds have passed since the last adjustment. If you block the unit by master appliance (NA entry) the display will show „EXT BLOCKED”. If the fault occurs the display will show icon and error message. Error messages:

• ER>T INLET - inlet sensor failure,

• ER> T MAX - temperature has exceeded the maximum value,

• ER> AIR 1 - air bubbles in the heating box - equipment detection,

• ER> AIR 2 - air bubbles in the heating box - program detection. If the display shows ER> T MAX, ER> AIR 1 or ER> AIR 2 the unit will stop heating. The unit will not heat again until the failure is resolved and the appropriate value of water ow is reached. Temperature adjustment The current temperature is displayed on LCD. Turn the knob to the right to increase the temperature value, or to the left to decrease it. Push the knob to read the temperature value that is stored in memory. Push it again to read the next stored value. You can switch between the following settings: „ECO”,„SINK” and „BATH”. To change the temperature setting in memory:

• select the temperature setting by pushing the control knob,

• push the knob and keep for about 3 seconds until the value starts to ashing,

• turn the knob to adjust the value,

• push the knob to save the value. Notice: save the new value within 10 seconds, otherwise you will lose it. KDE5 Operation The heater switches on automatically straight after reaching the ow rate over 2,5 l/min. The temperature control system adjusts the power rate according to the water ow rate, required temperature and the temperature of water in the mains. The LCD backlight and icon signalises the heating operation. If the unit reach the maximum power value which is too low for a given operating conditions the LCD display will show ickering icon . The LED display backlight also turns on while pushing or turning the setting knob. The backlight will automatically turn off when theDE;EN;FR;IL -099C_f.1290

Conguration and parameters view Set the minimum temperature value then push and keep knob for about 5 seconds until the display shows „>T SETPOINT”. Turn a knob to select the required value. There are some parameters that are not changeable by the user (e.g. >T INLET, >POWER), or can be used to change the work conguration only (e.g. display brightness, language version). To change the parameters value push (position ickering) and turn the knob. Push the knob to conrm a change. Notice: conrm a new parameter value within 10 seconds, otherwise you will lose it. The new parameter value will be saved when you exit menu using [>EXIT]. You can switch between the following parameters:

• [>T SETPOINT] temperature (min-max) - °C,

• [>POWER] percentage of maximum power with which the unit currently heats, -%,

• [>ENGLISH] select language version,

• [>TEMP LIMIT] maximum temperature limit (min setting - max setting), Notice: a new maximum temperature value will be saved in memory for other temperature settings as well, If you try to set the temperature above the adjusted maximum value the display will show for about 1 second.

• [>TEST] for authorized service only,

• [>POWER SET] congured power value, - push knob to check a software version (PW...,MSP...), - restore to factory settings [FACTORY SET] or to restart controllers [RESET], - push and keep knob (for about 5sec., until the display show [--]) to up grate [FACTORY SET] and [RESET] function,

• [>EXIT] save a new parameter and menu exit. Notice: parameters view mode will automatically exit (without saving changes) after 5 minutes since the last adjustment.18 Number of impulses (green indicator) Description

The unit was switched off because the temperature has exceeded the maximum value (fault signal will not disappear until the appropriate rate of water ow is reached). 2 The unit was switched off by a master appliance 3 The inlet temperature sensor failure

The unit was switched off because the air bubbles in the heating box (the unit will not heat again until the fault is resolved and the appropriate rate of ow is reached). The heater switches on automatically straight after reaching the ow rate over 2,5l/min. The temperature control system adjusts the power rate according to the water ow rate, required temperature and the water temperature in the mains. There are two indicators on the case: - green - power supply „on”, - red - heating „on”. Other modes are shown by ickering green light. KDE3 OperationDE;EN;FR;IL -099C_f.1290
