For instruction on how to replace the filter in the column heater’s in-line filter
unit, see page 136.
To install the column in-line filter:
1. Remove the O-ring retainer from the outlet end of the active preheater
or column stabilizer tubing.
Tip: Before connecting, make sure that the ferrule is approximately
3 mm from the end of the outlet tubing and that the collet is touching
the back of the ferrule.
Older, reusable fittings do not have holes in their sides.
Caution: To prevent contaminating system components, wear
powder-free, non-latex gloves when connecting tubing and tightening
fittings.
