BOWA SHE SHA smoke evacuation unit
MN009-940-S0 EN
Reading the Filter Life Indicator:
Install an unused SHE SHA filter into the system per the installation instructions contained in this
operator’s manual. When the system is turned on, the filter life indicator will light up the top orange
filter life indicator LED, indicating 100% filter life. The indicator will progress through vertically
allocated LED and the lowest LED will begin flashing RED to indicate that the filter has expended its
useful life and requires replacement.
When the maximum filter life is consumed and the smoke evacuator is not powered off for greater
than six (6) hours or the main power is disconnected – a new filter is required to activate the smoke
evacuator and make operational.

FUSES
(circuit board)
Two 8 AMP fuses are located on the circuit board within the housing of the system. It electrically
protects both the system and the operator from damage or injury. If the system is overheated or if
there is an electrical surge in the electrical system, fuses will break and the system will not operate.
When the Service light illuminates, please contact BOWA’s technical service for system service
instructions, see chapter 4 technical service.
