Quiet Function
• If you feel the unit is too loud for your environment, such as when you are sleeping, press the QUIET
MODE CONTROL button. The unit continues to heat and purify according to active modes, but the fan
runs on the most silent speed.
Standby Mode
• When the room exceeds set temperature by 2 Degrees F the heater goes into “STANDBY MODE”,
essentially turning off except the temperature sensor. After that, when the room drops 2 Degrees F below
the set temperature, the heater comes back to normal operation. This is because the heater radiates a
small amount of heat even when the fan is on the lowest setting, which would cause the heater to continue
raising the temperature of a small room indefinitely were it not for the “STANDBY MODE” feature.
Audible Notifications
• When the heater reaches the set temperature it will produce an audible tone to let the customer know.
It will produce the same tone when it goes into “STANDBY MODE”.
Maintaining The Unit
Cleaning the Filter
The filter should be cleaned every 30 days or more often if you find that the filter is collecting visible particulate.
1. Unplug the POWER CORD from the outlet.
2. Remove the FILTER ASSEMBLY SCREW using a screwdriver. Place the screw aside where you will not
misplace it.
3. Allow the FILTER ASSEMBLY to lean away from the rear of the unit until it is free to be removed.
4. Remove the FILTER from the FILTER ASSEMBLY by using a flat blade screwdriver to release the four
tabs of the FILTER COVER and then carefully lifting the FILTER from the FILTER ASSEMBLY.
5. Use a vacuum cleaner to remove built up particulate from the FILTER. Optionally, you can also clean
the FILTER using warm soapy water. If you opt to using water, ensure that the FILTER dries completely
before continuing.
6. Carefully replace the FILTER in the FILTER ASSEMBLY. Replace the FILTER COVER onto FILTER
ASSEMBLY and ensure all 4 tabs are in place.
7. Set the tabs of the FILTER ASSEMBLY in their place on the rear of the unit and pivot upwards until it is
properly seated.
8. Replace the FILTER ASSEMBLY SCREW using a screwdriver. Tighten until snug.
9. Plug the POWER CORD back into the outlet..
