OPERATION INSTRUCTIONS
Operation
1. Position the fan heater so that it is upright on
a firm, level surface and at a safe distance
from wet environments and flammable
objects.
2. Connect the fan heater to the proper electrical
power. See Grounding instructions below.
3. Set the thermostat dial to the maximum
temperature.
4. The fan heater will switch on when the
ambient air temperature is lower than the
desired thermostat setting.
5. Once the room reaches the desired
temperature, turn the thermostat dial back
until heating element turns off.
Automatic Overheat Safety Control
– This heater is equipped with safety internal
heat limiting thermostat and overheat
protection circuit. When a potential overheat
temperature is reached, the system will
automatically shut the heater off at 194 ºF
(90 ºC).
– The location, function, and operation of each
control of the heater are designed to reduce
the risk of fire, electric shock, or injury to
persons. Do not tampering with such devices.
Caution Light
– The Caution Light will illuminate when the
Overheat Safety Control is activated. The
heating element will be shut off until the unit
has cooled to a safe level.
– The fan will continue to operate.
– Once the heater has reached a safe level
(158 ºF / 70 ºc), the heater will turn back on
automatically.
Thermostat Instructions
– At first, set the thermostat to “+” and let the
heater operate with full power input. When
the room temperature reaches the required
value, turn the thermostat to the left until it
switches off.
– The thermostat will then switch on and off
automatically to control the room temperature
according to the preset value and keep the
room temperature constant.
– When using the heater for the first time, you
may notice a slight emission of smoke. This
is quite normal and it stops after a short
time. The heating element is made of steel
and was coated with a layer of protective oil
during production. The smoke is caused by
the leftover oil as it is heated.
