Press the switch once to select High-level heat-
ing. Press the switch a second time to select
Low-level heating. Press the switch a third time
to shut the heating elements Off.
When the High-level setting is selected, the heater will
provide a boosted heat level during the first four minutes
of operation. Then, the heat output will drop to the
normal High-level. If the High-level setting is selected,
the system will automatically switch to Low-level after
approximately 30 minutes of continuous operation. At
that time, the number of illuminated LEDs changes from
two to one, indicating the change. The Low-level setting
will turn Off automatically after approximately 30 min-
utes.
NOTE: Once a heat setting is selected, heat will be felt
within two to five minutes.
