Maintenance

Disconnect the unit from all power sources before servicing. The unit may be
energized from multiple sources. The potential for electric shock exists.

Cleaning

The outside surface of the unit should be wiped free of dust and dirt when necessary. 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.


Load
Check the center and outer conductors for visible damage or excessive wear

Hoses
