Replacing the Internal Filter
CAUTION
To avoid damage to internal circuitry, remove the batteries before
opening main housing.
1. Turn off the Innova, remove batteries, and then separate the halves.
2. Locate the internal filter, see Figure 6-2. It is connected to the inlet
fitting by a small polyurethane tube.
3. Disconnect the polyurethane tubes from the slip-on barbs on the filter.
4. Push the tubes onto the barbs on the new filter, close and secure the
Innova, and re-install batteries.
Replacing the Probe's Hydrophobic Filter
1. Unscrew the probe body's two halves. Be careful not to lose the o-
rings that seal the filter.
2. Remove the filter and cotton ball from the probe half that mounts to the
Innova (you may need to use a small screwdriver to pry the filter loose).
3. Install the new filter and cotton ball in place of the filter and cotton ball
you removed.
4. Make sure the O-rings are in place, then reassemble the probe halves.
