INSPECTION AND MAINTENANCE
1.
Annually
(also recommended when main te nance is performed)
• All safety devices in the control circuit should be cycled on and off to
verify they are functioning. These include:
– High limit switch
– Airfl ow proving switch
– Low water cutoff switch
• Measure current draw of heaters and verify amp values per stage by
comparing to the wiring diagram located inside the control cabinet. This
identifi es any burned out heaters. Only qualifi ed electrical personnel
should perform this task.
• Inspect tank and gaskets for leaks.
• Verify that the fl oat valve is closing off. If the fl oat valve will not shut off,
there may be particulate on the valve seat, or the stopper may be worn
and need replacing.
• As long as mineral-free water is used in the RO/DI-water Vaporstream,
no cleaning or fl ushing of the humidifi er should be necessary.
2. Off-season maintenance
• Perform a complete inspection of the following:
– Heaters
– Float
valve
– Low water cutoff switch
– Humidifi er tank and gaskets
• After inspection, the humidifi er should remain empty until humidifi cation
is required.
Inspection and maintenance
Recommendations for RO/DI water
humidifiers
Verify regularly that water processing
equipment is operating correctly. The presence
of chlorides in improperly processed DI water
can cause pitting and failure of the tank and its
components. Your DriSteem warranty does not
cover damage caused by chloride corrosion.
Vaporstream humidifi ers with RO/DI water
option:
•
Do not require regular cleaning, although
regular inspections are advised.
•
Do not require skimming or draining and
fl ushing to remove precipitated minerals;
however, all RO/DI humidifi ers should
be drained at the end of a humidifi cation
season either by manually opening the drain
valve or by programming the humidifi er to
automatically drain at end-of-season (electric
fi ll and drain valve required).
