4.4 Replacing the Refrigerant Identifier Filter
Caution:
Visually inspect the Refrigerant Identifier Filter every day. If
it begins to turn red, replace it immediately! You risk damaging the
identifier sensor if the filter is not replaced.
The refrigerant identifier filter is located on the control panel, directly
under the Low Side pressure gauge. The filter’s function is to protect
the refrigerant identifier sensor from contaminates. When this filter
starts to develop red spots, replace the filter immediately!
1. Remove the filter from its holder; then remove the tubing from
each end.
2. Position the new filter so that its flow-arrow points in the same
direction as the flow-arrow on the control panel.
3. Attach the tubing to the new filter, and press the filter back into
its holder.
