Water connections with 12 mm compression fittings
s 5NIVERSALMOUNTINGFRAME
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 unfinished 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).
