Adding Water to Humidifier:
So that you can humidify the air your RHFE-UNIT
is fitted with an enamelled tray behind the air
outlet. To fill the tray, open the door as shown
in the diagram and pour water into the tray using
the spout built into the door. The air will be
humidified as it passes over the water in the tray.
DO NOT FILL THE TRAY WHILE THE UNIT IS
IN OPERATION. CLOSE THE DOOR AFTER
FILLING. The RHFE UNIT is a very high
efficiency appliance,during operation a small
amount of water is produced in the vent tubes,this
drains into the enamel tray. It is quite normal for a
small quantity of water to remain in the bottom of
the tray.
Caution:
● The humidifier tray and the surrounding area are
hot when the unit is on. To avoid burns, do not add water to the tray while unit is on.
● Avoid adding water when the room is susceptible to condensation.
● If the water overflows from the water level hole when adding water, do not add any more water.
Care of Unit Exterior:
Dampen soft cloth with warm water, wring water out well and
wipe the unit.
Caution:
Never use volatile substances such as benzine or thinners, as
they cause fading of paint or deformation of resin.
Care of Air Filter:
Always clean the air filter when the filter indicator lamp starts blinking.
■ The filter indicator lamp starts blinking when the dust accumulates on the air filter. In this event, turn
the unit off immediately, wait until the unit cools off and clean the filter.
■ Even if the lamp is not blinking, if you think the filter is dirty, clean the filter while you are cleaning the
room. This will ensure comfortable use.
■ The air filter may be removed. Clean both sides of the filter with a
vacuum cleaner or a duster.
■ If the filter is greasy, wash quickly with detergent, shake water off and
dry completely.
■ After cleaning and drying, replace the filter securely.
CAUTION:
● If you continue to use the heater with the filter indicator lamp flashing, the sensor may detect trouble
and turn the unit off. Causing the room temperature display lamp "14" and the
"operation/combustion" lamp to flash , indicating that the safety device has been activated. In this
event, clean the air filter immediately as above.
