• Clean the skim/overflow port
– Water should drain from the skimmer drain pipe after
each fill cycle. This should be verified visually by a weekly
inspection.
– Loosen deposits in and around the skimmer/overflow port
with a long tool such as a screwdriver.
– If flow through the water seal/P-trap is diminished due to
mineral accumulation:
• Remove the water seal piping from the humidifier and
flush out.
• Replace the water seal with new piping if the minerals
have hardened in the water seal.
• Clean low water cutout probe — Remove the shroud cover
and inspect the probe rod for mineral accumulation. The rod
is located on the top of the tank near the back. Use stainless
steel wool to clean the probe .
• Inspect blower motor — A lubrication port is not provided,
therefore lubrication is not required.
• Remove dust — Using a vacuum, remove all dust from areas
around the motor, vent fan(s), and louvers that allow air to
the shrouded area.
