• Appliance must only be installed in frost-free rooms. Never expose appliance to
frost.
• The Appliance must be wall mounted and has to be installed with water connectors
downward or alternative transversely with water connections left.
• The appliance complies with protection type IP25 and may therefore be installed in

• In order to avoid thermal losses, the distance between the instantaneous water
heater and the tap connection should be as small as possible.
• The appliance must be accessible for maintenance work.
• Plastic pipes may only be used if they conform to DIN 16893, Series 2.

Mounting accessories

For installations under difficult conditions, these mounting accessories are available:
Mounting frame kit RDX3
(Art. no. 36100)
The instant water heater can be installed by means of this mounting kit in the below
situations. The power supply cable is coming out of the wall at any place from behind
the unit, but the wall has unusual surface conditions, making it difficult for installing
the water heater.
When using the RDX the protection class changes from IP25 to IP24.
Extension kit VDX
(Art. no. 34120) – RDX / RDX 3 is necessary! –
The instant water heater can be installed by means of this extension kit if the water
pipes are coming displaced or exchanged out of the wall or if they are coming edge-
wise on the wall to the unit. The power supply could come out of the wall at any place
under the unit or the wiring could be installed surface-mounted.
Extension kit UDX
(Art. no. 34110) – RDX / RDX 3 is necessary! –
The instant water heater can be installed by means of this extension kit if the water-
connections are expiring above the unit. The power supply could come out of the wall
at any place under the unit or the wiring could be installed surface-mounted.
