8.6 Special accessories
Special accessories are available from your local supplier.
Direct tap instantaneous water heaters
ADEo 70 WD - Mono-lever mixer tap with changeover
bath / hand shower.
Wireless remote control
FBM Comfort
Installation accessories
Finished walls, G 3/8”, top. Water connections with
12 mm compression ttings.
Universal mounting frame
Mounting frame with electrical wiring. This assembly
creates a gap of 30 mm between the appliance back
panel and the installation wall. This enables the power
supply to be freely routed over unnished walls behind
the appliance. This increases the appliance depth by
30 mm. This set reduces the protection level to IP 24
(splashproof).
Offset installation pipe assembly
Universal mounting frame (for technical description,
see “Universal mounting frame”) and pipe bends for
the vertical offset of the appliance against the water
connection by 90 mm downwards.
Gas boiler replacement pipework set
Universal mounting frame (for technical description, see
“Universal mounting frame”) and pipe bends for installation
using existing gas red water heater connections (cold
water connection on the left; DHW connection on the
right).
Load shedding relay LR 1-A
The load shedding relay enables operation with, for
example, electric storage heaters. The instantaneous
water heater is operated via the load shedding relay prior
to any other appliance.
