• FILTER LIFE INDICATOR
(Membrane Control Panel)
The filter life indicator on the membrane control panel provides a visual indication of the status of
the life of the filter in use. The filter life indicator for the ViroVac™ Smoke Evacuation System will
automatically adjust according to the flow setting selected.
Low Flow Setting = 35 hours of filter life
Medium Flow Setting = 24 hours of filter life
High Flow Setting = 18 hours of filter life
The ViroVac™ Filter Life Indicator is factory set. All filter life timing is automatic.
Reading the Filter Life Indicator:
Install an unused ViroSafe® Filter into the system per the installation instructions contained in
this operator's manual. When the system is turned on, the filter life indicator with light up the
leftmost GREEN LED, indicating 100% filter life. The indicator will progress thru subsequent
GREEN LEDs, to an AMBER LED as time elapses and 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 acti-
vate the smoke evacuator and make operational.
• FUSES
(circuit board)
Two 10 AMP fuses (8 AMP for 220/240 ViroVac™ systems) 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 BUFFALO FILTER Customer Service for
system service instructions.
