Maintenance
DI/RO humidifiers use DI/RO water. Because these water types
are mineral free, cleaning the evaporating chamber should not be
necessary. However, there are some maintenance steps that should
be followed to ensure all parts of the unit are in working order.
Important: Verify regularly that water processing equipment
is operating correctly. The presence of chlorides in improperly
processed deionized water will eventually cause pitting and failure
of the humidifier tank and its components. Damage caused by
chloride corrosion is not covered by your DRI-STEEM warranty.
Cool down humidifier
If the tank is hot, cool it down by opening the manual ball valve on
the side of the tank. The float valve will open allowing cool water
to run into the tank until it is cool enough to handle. Then shut off
the water supply, and allow the tank to drain completely.
Inspection and maintenance
1. Remove the evaporating chamber:
• If the tank is hot, follow the instructions in “Cool down
humidifier” above before proceeding.
• Shut off the water supply.
• Allow the tank to drain completely.
• Shut off the electrical supply.
• Disconnect the fill line at the fill fitting.
• Disconnect the electrical plugs between the tank components
and the back of the electrical panel (includes: power plug,
low water switch plug, tank temperature sensor plug and
thermal trip plug).
Important: Disconnect by pulling on plug housing. Do
not disconnect by pulling on cord or wires.
• Disconnect the drain union on the back left corner of the
frame.
• Disconnect the steam supply hose from the top of the tank.
• Lift the tank foot above the frame flange and slide the tank
assembly forward to remove.
2. Loosen the four cover bolts and remove the cover assembly from
the tank.
3. Inspect the tank interior for debris or pitting.
4. Inspect the valve inlet for debris.
5. Check the operation of the float valve and the condition of the
float seat.
6. Check the low water switch to make sure the float slides freely
on the stem.
