Rinnai RHFE-263FA Owner's Operation And Installation Manual page 31

Adding Water to Humidifier:
Remove the bottom trim panel, below the louvers,
by pulling on both sides. Simply pull the tray
forward to allow it to be filled with water. The warm
air will be humidified as it passes over the water
in the tray. Refit the bottom trim panel after filling
the tray. The RHFE-263FA is a very high efficiency
appliance. During operation a small amount of
condensation is produced in the flue system. This
drains into the enamelled humidifier 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 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. This will cause the room temperature display lamp to code"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 instructed above.
