The flow should be at least 30 liter/min
when a vacuum of 250mm/Hg is applied.
The flow should be at least 1.6 liter/min
when a vacuum of 320mm/Hg is applied.
Check each connecting tube for cracks or
damage and replace if necessary.
INSTALLATION

x The secondary air cleaner must be
assembled and installed properly to
avoid dust entering the air cleaner.
x When installing, be careful not to
bend or twist the tubes and check for
proper installation.
x The tube length is very important to
its performance, use the tube of
same specification for replacement.
