Why does the blower fan keep running after I have turned off the ON/OFF switch?
The blower fan will continue to run until the proprietary heat chambers have cooled down. After a few minutes the fan will shut off
automatically.
The heater’s airow seems to have diminished.
Make sure the intake is not blocked and that the lter is clean. Follow the Filter Maintenance procedure.
Will I be able to use the heater in a basement or garage?
Yes, but keep in mind that rooms with little insulation will not retain the heat as efciently. Bare concrete oors, which act as a
heat sink with any type of heating, will absorb some of the heat. Placing the heater a few feet above the oor will allow for
more efcient heating.
Can I use more than one heater at a time?
Yes, but you should make sure they are not on the same circuit. Each heater and/or appliance should be on its own circuit.
Can I move the heater around while it is operating?
It is not recommended to move any portable heater while it is operating. We recommend moving the heater only after the fan
has completely turned off.
Can I use the heater and another appliance at the same time?
Yes, as long as they are not on the same circuit. Zone heaters are considered to be an appliance. You should not run more
than one large appliance on a single circuit breaker. Your freezer, refrigerator, microwave oven, washing machine, dryer, and
other such appliances should not share a circuit breaker.
I pressed the power button on the display but the heater won’t turn on. What should I do?
Make sure the main Power Supply button on the back of the heater is turned on.
My heater lost power. What should I do?
Unplug from wall, check lter to make certain that it is clean, and plug back in. If unit does not power up or shuts down again,
please call 1-800-225-6595 or visit www.edenpuresupport.com.
Why doesn’t the temperature on my heater match the temperature display on my wall or external thermostat?
If using the Celsius or Fahrenheit temperature display for your heater, the temperature on your heater may vary from the tem
-
perature display on another thermostat (like the one mounted on your wall or a purchased external thermostat). The temperature
sensor on your heater reads the temperature in and around the heater. The unit is near a cold oor, and heat rises, so it will detect
and display a cooler temperature than elevated or external thermostats. The best way to operate your heater is to just set it to
a temperature that feels comfortable to you.
SERVICE – For repairs or service, please call 1-800-225-6595 or visit www.edenpuresupport.com.
WARNING
ANY REQUIRED SERVICE OTHER THAN FILTER MAINTENANCE SHOULD ONLY BE PERFORMED BY A QUALIFIED ELECTRICIAN.
To assure maximum performance of the EdenPURE
®
heater, please note the following recommendations:
1) For best results, do not locate the heater in an area with a high rate of air ltration and movement as the warm air will be
exhausted.
2) Try placing the heater near a warmer inside wall and direct the output toward a cooler outside wall. The cooler outside wall
will tend to draw the generated heat toward itself, which will allow for more efcient heating.
3) Placing the heater next to a cold air return will draw the heat away from area to be heated. Try closing or covering the cold
air return. This will allow for more efcient heating. Experiment with the placement of the heater to see what works best for
you.
4) To ensure maximum efciency, a 40% (minimum) relative humidity should be maintained in the heated environment.
5) In rooms with large areas of bare concrete, try placing the heater a few feet above the oor. Make sure the heater is secure
and won’t fall. This will allow for more efcient heating since concrete acts as a heat sink and will tend to draw the heat in
its direction.
6) Try setting your central heating system to a lower temperature and placing the heater in the area you spend the majority of
your time. Now set the EdenPURE
®
heater to your comfort level. After all, there is no point to heating multiple rooms to 68+
degrees when they are not in use.
7) If used in an extremely dirty or dusty area, the lter must be cleaned more frequently as it can clog and cause the heater to stop
working.
8) Extreme caution is necessary when any heater is used by or near children or invalids and whenever the heater is left operating and
unattended.
9) To disconnect the heater, press power supply button on the back of the heater to “off,” then remove plug from outlet once it has
stopped running.
10) Always unplug heater when not in use.
RECOMMENDATIONS
TROUBLESHOOTING
1) Unpackage heater. We recommend keeping the packaging for off-season storage and any transporting needs.
2) Find a level and unobstructed location to place the unpackaged heater.
3) Plug the power cord directly into an unused grounded 110 volt 15 amp or higher circuit receptacle.
4) Remove the tab in the remote control to activate the battery of the remote control.
5) Make sure the POWER SUPPLY button, on the back of the unit, is in the ON position.
6) Press the POWER button in the control panel to turn on the heater.
7) To turn the heater off, press the POWER button; the fan will continue to run until all of the heat has been expelled.
