Mains connection lead 20 150 The connection cable must project from the wall over an insulated length of at least 20 mm. Mains connection on top 1 2 3 max.10 4 Electrical connection terminal (3) factory-prefitted. Cut out cable inlet opening (1). Slide flexible inlet bush (2) over connection cable, insert it through the back wall opening, and screw fixing strap under connection terminal (4). 13 Mains connection underneath (alternative) 3 2 1 For this connection version, transpose the mains connection terminal (1) from top to bottom. Note the terminal designation on the back wall, and do not cross the connection leads to the safety temperature limiter. Carry out cable inlet opening (2), inlet bush (3), and bush fixing under the mains connection terminal as described above for mains connection. Important! Moisture protection is only guaranteed with the inlet bush fitted in position.

Important! Before dismantling, set the knob to the minimum temperature of 30°C. Detach the temperatur set-point pickup (2) in the appliance hood. Turn the setting dial (3) so that the printed set- point coincides with the hood mark (1). Do not twist the selector axis and plate of the temperature set-point pickup when reassembling! Plug the connection lead of the temperature set-point pickup into the electronic system, suspend the appliance hood in the upper edge of the back wall, and swivel it downwards until it audibly engages. If necessary, the hood can be supplimentarily fixed with a screw next to the engagement lug. 15 Using the appliance for the first time and checking The unit must be installed and started up by an approved firm of installers which accepts liability for safety and proper function. Before the appliance is energised (connected to the electricity supply), it should be thoroughly flushed with cold water and the tightness of the screwed joints checked. After the instantaneous water heater is energised (connected to the electricity supply), it should be inspected by a trained engineer to ensure that it is in proper working order. For protection of the heating systems, the system is arranged for a switch-on delay of 5 - 25 s at initial startup and after the appliance has not been live for any length of time. Important: After any work carried out on the water supply unit, the appliance should also be thoroughly flushed with cold water (vented) before being switched on again. Only then should the appliance be reconnected to the electricity supply. After initial startup, the user should be familiarised with operation of the appliance and the instructions for installation and use handed over for safekeeping. 16 Fault-finding (important instructions for the trained engineer) In the event of any fault, a check should first be made to ascertainwhether the fuse and line protection switch have tripped. Fault Cause Remedy -Heating system does not switch on -Appliance is not live Check the voltage -Hot water flowrate too low - Strainer insert is clogged Clean strainer insert (see page 12) Dismantle and clean the -Soiling or scaling of bubblers and showers bubblers and shower heads heads Inspection and repair only -Defective heating by the trained engineer system -Inadmissibly high cold Appliance should not be -Safety temperature and water inlet tempera- operated with preheated pressure limiter has ture (over 25 °C) water. tripped -Inadmissibly high Inspection and repair only outlet temperature by the trained engineer (over 70 °C) Inspection and repair only -System fault (see -Active fault indicator by the trained engineer table on page 18) (LED) 17 Fault indications Fault pattern Idicator LED 1 LED 2 Possible faults 1 No display Appliance does not work Setpoint temperature not reachd No display -L1 or L3 phase missing -L2 phase missing -Flowrate sensor not plugged / defective 2 FLASHES long FLASHES long warm water temp. 37°C Constant -Setpoint generator not fitted 3 FLASHES long FLASHES short No heat output -Electronics defective 4 5 FLASHES long ON No heat output ON No heat output -Supply temperature over 25°C -Water flow over 20l/min *) The individual fault are indicated every 5 sec. The indication mode starts afresh every 40 sec. Important! If the fault has been rectified, the fault memory goes automatically in Reset -Function.(Sometimes with cold water flow phase ca.15 sec.) 18 Important for the expert The electronic controls the safety-function of the appliance. When a fault is noticed, the fault indicator (LED) blinks and the heating element is switched off. After the fault has been recitified, fault memory will be automatically cancelled Instructions for the fault finding see in "Instructions for installation and use"...
