6.4. 2 BOXES CONNECTION SET
To install two HYGIENE BOXES, you need the 2 Boxes Connection Set (KBN-Nr. COSHYGBOXAS2B),
which includes two additional flexible hoses, a waste water hose and a communication cable with
USB-C port.
Mount the second HygBox using the other angle valve and connect the two flexible hoses, the waste
water hose and the humidity sensor (p. 8 - Chap 4.4. Design of Control unit) an.
For easier installation of the drain hose, use the John Guest angle coupling (included in each connec-
tion set).
