PLEASE NOTE

In some cases, the actual Watts product will show a model revision level after the part number, for example F602-02- BJ M5.  The M5, not shown in the catalog, is the Model Revision Level. Please specify this Model Revision Level when ordering repair or replacement kits.  We will then be sure to provide the correct kit.  The model revision level need not be specified when ordering a new product as you will automatically be provided the latest model revision.

WARNING

The plastic material used to manufacture the plastic bowls, and the sight glass on metal bowls, may be attacked by certain chemicals.  Do not use these bowls on systems with air supplied by a compressor lubricated with synthetic oils or oils containing phosphate esters or chlorinated hydrocarbons.  These oils can carry over into the air lines and chemically attack and possibly rupture the bowl or sight glass.  Also, do not expose the bowl or sight glass to materials such as carbon tetrachloride, trichlorethylene, acetone, paint thinner, cleaning fluids, or other harmful material, for they too will cause the plastic to craze and /or rupture.  For use in environments where these, or any, chemicals may be present, consult the factory for approval.
