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
™
.
The best way to determine how often your humidifier needs
maintenance is to remove the tank cover and inspect it for mineral
deposits after three months of duty. Hours of operation and duty
cycle will determine your maintenance schedule, as will water
quality.
Water quality and maintenance
Maintenance requirements vary with water quality, because tap and
softened water carry a variety of minerals and other materials in a
mix that varies from location to location. Very hard (high mineral
content) water requires more frequent cleaning and drain/flush
cycles than water with low mineral content.
Softened water significantly reduces mineral accumulation inside
the humidifier
.
Note: S
olids, like silica, are not removed in the softening process.
Skim duration
Skim duration determines the quantity of water skimmed with
each fill cycle and is field adjustable using the Vapor-logic4
keypad/display.
Skimming reduces the need for frequent humidifier cleaning.
Each time the tank refills, it fills to a level just above the lip of the
skim/overflow fitting. A portion of the fill water flows out of the
skim/overflow fitting to the drain, which flushes minerals left by the
previous evaporating cycle and skims away surface residue.
Both humidifier cleaning and heated water flowing to the drain are
operational costs. DRI-STEEM recommends that the user observe
and adjust the skim duration to achieve a balance between reducing
mineral buildup and conserving heated water.
WARNING
Electric shock hazard
Contact with energized circuits
can cause severe personal injury or
death as a result of electric shock. To
prevent shock, disconnect electrical
power before performing service or
maintenance procedures on an part of
the humidification system.
