MAINTENANCE/REPAIRS
5.1
Periodic General Maintenance
Systematic, preventive maintenance of the humidifier is recommended for optimum system performance. Routine
periodic maintenance should include, but is not limited to the following:
Tightening electrical connections.
Cleaning, inspecting the unit’s components visually.
Checking the level of water and ensuring no leaks are present.
A system should be established to record any problems, defects or deficiencies noted by operators and discov-
ered during maintenance inspections, together with the actions taken. For assistance, contact the SATS Product
Support Group. Ensure adherence to all safety precautions while performing any type of maintenance.
5.1.1
General
Before the maintenance inspection and repairs are done, be sure to set the power supply circuit breaker (main
switch) to OFF and close the water supply valve.
WARNING
Turn off power to the unit unless you are performing tests that require power. With power and controls
energized, the unit could begin operating automatically at any time.
CAUTION
The transducer is a very delicate part. When the water tank interior is cleaned, special care must be taken to
ensure the transducer is not scratched on the surface with a screwdriver, etc.
Do not supply power to the ultrasonic nebulizer units while the transducer lead wires (yellow and orange) are
removed.
Proper tools must be used. Excessive tightening or insufficient tightening may cause failure.
When performing maintenance or repairs, care must be taken to ensure small parts such as screws will not
be lost.
Care must be taken avoid injury by sharp edges of the sheet metal, etc.
Solid scaffolding must be provided for working in high places.
Testing insulation resistance and dielectric withstand voltage should be avoided because the humidifier incor-
porates sensitive electronic parts.
When parts are replaced, genuine SATS parts must be used. Contact SATS Product Support Group for
assistance.
