RBF WIRING DIAGRAM
How to operate your heater
Once installation is complete and power has been
restored, turn the heater switch on. Important: The
heater will remain on until it is manually turned off.
Maintenance
As needed, or every six months, minimum.
1. WARNING! Before removing grill, turn the
electrical power off at the electrical panel board
(circuit breaker or fuse box). Lock or tag the panel
board door to prevent someone from accidentally
turning the power on while you are working on the
heater. Failure to do so could result in serious
electrical shock, burns, or possible death.
2. It is important that you verify power has been
turned off and no power is going to the heater
before proceeding. Circuit breakers are often not
marked correctly and turning the wrong breaker
off could mean electricity is flowing to the heater,
even if the heater does not appear to be working.
If you are uncomfortable working with electrical
appliances, unable to follow these guidelines,
or do not have the necessary equipment, consult
a qualified electrician.
3. Once you verify the power has been turned off
correctly, proceed to next step.
4. Remove screws and take off grill.
5. Wash grill with hot soapy water and dry immediately.
6. While holding fan (to avoid damage or bending), use
a hair dryer or vacuum on blow cycle to blow debris
through the top element (do not touch element).
7. Vacuum fan area without touching the elements.
8. Replace grill and secure with screws.
9. Turn power back on at the electrical panel board.
About the Heater Temperature-Limiting Controls
The heater is protected by two temperature-limiting
controls. Both controls are integral parts of the
element assembly. The first is a manual power reset
limit control, designed to open the heater circuit when
excessive operating temperatures are detected. The
problem must be assessed and the limit must be reset
to resume operation.
Operation & Maintenance
Further protection is provided by a secondary
over-temperature fuse, which will open the heater
circuit in severe over-temperature conditions, or in
the event of component failure. If this occurs, the
heater must be repaired or replaced.
RESETTING THE MANUAL POWER RESET
LIMIT CONTROL
If the manual power reset limit has opened the
heater circuit due to excessive operating
temperatures, the heater will not work until it is
reset. This can be done at the ON/OFF rocker
switch control or the circuit breaker controlling
the heater.
To reset heater at the ON/OFF
rocker switch control
1. Change rocker switch control to OFF position.
2. Allow the unit to cool for at least 10 minutes.
3. Resolve the problem causing the limit to trip
(typically the heater is blocked or needs
cleaning, see Maintenance Instructions).
4. Change rocker switch control to the ON
position. The heater should come back on.
To reset heater at the circuit breaker
1. Trip the breaker by switching it to the
OFF position.
2. Allow the unit to cool for at least 10 minutes.
3. Resolve the problem causing the limit to trip
(typically the heater is blocked or needs
cleaning, see Maintenance Instructions).
4. Restore power to the heater by switching the
breaker to the ON position.
5. The heater should come back on.
Note that resetting the manual power reset
control may not restore heater operation if
a severe over-temperature condition has
occurred. See the Troubleshooting Guide
below for more information.
