How to Maintain Your Humidier

DANGER: To avoid electrical shock or burn, turn

off the power supplying this equipment before

servicing.

To maintain high evaporating efciency of your Model 55 or Model 86

humidier, 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 humidication season (i.e., in the spring), clean the

humidier thoroughly, and turn off the water and electrical power to the unit

until the following season.

CAUTION: Do not leave water in the humidier 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 Humidier Pan (Model

55)”, page 11.

Wash all plastic and metal parts (except electrical parts) in humidier

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 humidier to automatic operation mode by following the

nal assembly instructions for Model 55 on page 11.
