For contractors

•฀ Direct฀tap฀instantaneous฀water฀heaters

ADEo 70 WD - mono-lever mixer tap with changeover bath/hand shower

Part no. 18 39 34

•฀ Installation฀accessories

Pipe assembly undersink installation UT 104

Part no. 18 44 21

฀ Water฀connections฀with฀12฀mm฀compression฀ittings

•฀ Universal฀mounting฀frame

Part no. 22 77 01

Comprising:

  –  Mounting frame with 

–  electrical wiring.

This assembly creates a gap of 30 mm between the device back panel and the installation wall.

฀ This฀enables฀the฀power฀supply฀to฀be฀routed฀over฀uninished฀walls฀at฀any฀point฀behind฀the฀device.฀This฀

increases฀the฀equipment฀depth฀by฀30฀mm.฀This฀set฀reduces฀the฀protection฀to฀IP฀24฀(splash-proof).

•฀ Offset฀installation฀set฀for฀uninished฀walls

Part no. 22 77 02

Comprising:

  –  Universal mounting frame (for technical description, see part no. 22 77 01). 

–  Pipe bends for a vertical offset of the device relative to the water connection by 90 mm downwards.

•฀ Pipe฀assembly,฀replacement฀of฀a฀gas฀ired฀water฀heater

Part no. 22 77 03

   Comprising:

  –  Universal mounting frame (for a technical description see part no.  22 77 01) 
  –  Pipe bends for the installation with existing gas water heater connections  

(cold water on the left and DHW on the right).

•฀ Maximum฀demand฀relay฀LR฀1-A

Part no. 00 17 86

Priority control of the instantaneous water heater when operating, for example, electric storage heaters 

simultaneously. For connection of the LR 1-A, see
