Cleaning
The outside surface of the unit should be wiped free of dust and dirt when nec-
essary. Clean the RF connector, both metallic and insulating surfaces, with a
dry, non-residue forming solvent.
If the optional water flow switch is installed, periodically remove it from the load
and clean off any dirt or scale which might prevent the switch from functioning.

Routinely inspect the following components:
z Load
Check the center and outer conductors for visible damage or excessive
wear
z Hoses
Check for cracks or deterioration. Make sure the hoses are securely
fastened to the load.
