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:

WARNING
Hot surface and hot water hazard
Do not touch the tank or drain piping until
the unit has had sufficient time to cool, or
serious injury can occur.
Opening the drain valve when the
tank is hot can discharge water with a
temperature up to 212 °F (100 °C) into the
plumbing system. This can cause damage
to the plumbing system if the humidifier
is not properly connected to a water
tempering device such as a DRI-STEEM
Drane-kooler
™
.
WARNING
Electric shock hazard
Do not remove humidifier electrical panel
cover, heater terminal cover, or subpanel
access panels until electrical power is
disconnected. Improper wiring or contact
with energized circuits can cause property
damage, severe personal injury, or death
as a result of electric shock and/or fire.
Only qualified electrical personnel should
perform maintenance procedures.
