signal lines, installing switches and power fuses and connecting the purge air supply.
3.3.3 Installing the purge air supply
▸ Lay the purge air hoses with shortest paths and free of bends, shorten as required.
▸ Maintain sufficient distance from hot duct walls.

Connect the DN40 purge air hose to the purge air outlets on the underside of the MCU-P
and secure with a strap retainer. Set the purge air outlets as shown (correct when nec-
essary).
