Withdraw the filter Part Number 321-012-005. Carefully clean the
filter element by means of a brush or vacuum cleaner, or wash it in
luke-warm water with grit-free soap. In case the filter element is
damaged, replace it. Before reassembling the Range Selector,
carefully clean all parts.
To install the cleaned or replacement filter, slip the bore of the filter
over the protruding nipple portion of the lower Range Selector part.
Place the filter element onto the lower Range Selector part with the
open end down. Then slip the probe socket over the protruding
nipple portion. Carefully align all three outside diameters of the
lower Range Selector part, the filter and the probe socket. Slip all
three parts into the upper Range Selector housing so that the air vent
switch button protruding from the lower Range Selector assembly
aligns with the channel in the upper Range Selector assembly. Exert
slight pressure when inserting the Phillips Head screw and lightly
tighten both Phillips Head screws.

Replacement of O-Rings in Probes

To replace the O-ring in the probes remove the old O-ring by means
of a hook-shaped tool, or by squeezing. Clean the O-ring groove
before installing the new O-ring. Slip the new O-ring in place and
apply a thin film of Silicone grease or lubricant on the outside of it.
The O-ring Part Number 342-006-048 fits all Velometer probes.

Replacement of O-Rings on the Meter

Replace the O-rings of the meter connection ports first by removing
the old O-rings using a hood or by squeezing; clean the grooves and
then slip new O-rings Part Number 342-006-030 in place.
