FIXED TIME PERIOD OPERAlTION.
The Energysaver RHFE-556FDT includes an option so that operation
of the appliance automatically stops after a fixed time period.
It is possible to choose any one of seven time periods. The periods
are: 1, 2, 3, 6, 8, 10 or 12 hours.
This option must be activated by a qualified person or trained Rinnai
service person.
Fixed time period operation is ideally suited to classroom situations,
clubs, meeting halls, and other areas where a limit is required on the
length of time the appliance operates.
The feature can provide substantial energy savings in cases where
users are likely to forget to turn the appliance off when they leave the
room after meetings or lessons.
If a power failure occurs at any time during operation, the appliance
will remain OFF once the power is re-instated. The ON/OFF button
must be pressed to re-ignite the appliance.

n HUMIDIFIER TRAY
F F
So that you can humidify the air, your Rinnai RHFE-556FDT is fitted with an enamelled tray at
the bottom of the heater. If you choose to make use of the humidifier tray, it will need filling
about once a day during the heating season. Do not fill the humidifier tray while the heater
is running.
L /
LJ
1 To fill the humidifier tray:
Remove the bottom trim panel, below the louvres,
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
I I
water in the tray. Refit the bottom trim panel after
filling the tray. The RHFE-556FDT 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.
he humidifier has the benefit (when filled with water) of raising the humidity in the air. With increased
humidity, the heater can actually be run at a lower temperature while still maintaining the same level
H VERTICAL LOUVRE ADJUSTMENT
The warm air flow direction may be altered by
inserting a screwdriver or similar tool and gently
bending the vertical louvre(s) either to the left or the
right.
Note: these louvres are not designed to be
adjust&f more than’6 times.
