How to Maintain Your Humidifier
DANGER:
to avoid electrical shock or burn, turn
off the power supplying this equipment before
servicing.
To maintain high evaporating efficiency of your
Model 55
or
Model 86
humidifier, replace the evaporator pad at least once a year (e.g., at the end
of each heating/humidifying season). In hard water areas, cleaning may
be required every three-to-four weeks; in soft water areas, cleaning may
be required every four-to-eight weeks.
At the end of each humidification season (i.e., in the spring), clean the
humidifier thoroughly, and turn off the water and electrical power to the unit
until the following season.
CAUTION:
Do not leave water in the humidifier pan
over the non-humidifying months!
For standard maintenance of
Model 55
, follow these instructions:
Shut off the water supply.
Lift out the distribution tray and evaporator pad assembly by reversing
the procedure found in #2 under “Installing the Humidifier Pan (Model
55)”, page 11.
Wash all plastic and metal parts (except electrical parts) in humidifier
cleaner or a 50/50 solution of vinegar and water. Rinse all parts
thoroughly with fresh water.
Wipe loose sediment from the water tray.
CAUTION:
Make sure no particles are allowed to plug
the drain hole.
Replace the evaporator pad.
NOTE:
Annual replacement of the evaporator pad is
recommended. Severe clogging of the pores may require
replacing the pad more frequently.
Restore the humidifier to automatic operation mode by following the
final assembly instructions for
Model 55
on page 11.
