If the heater cycles ON/OFF without heating:

Please note: This is a smart heater that monitors the room temperature and produces heat only when needed. You can set the desired room temperature with the heater in ECO mode (factory default is 68 °F). For example, if you set the temperature for 70 °F, the heater will run on HIGH until the room temperature reaches 70°F, then switch to LOW for 10 minutes. It may then enter NAP mode for energy saving, turning off if the room temperature is equal to or greater than 69°F. It will run on HIGH again when the temperature drops to 68°F. The heater remains on STANDBY as long as you do not POWER OFF. While on STANDBY, it reads room temperature every 5 minutes (heating for 40 seconds, fan for 60 seconds) to ensure accurate readings. If the room temperature is 72°F or higher, it remains on STANDBY. If the room temperature drops 2 degrees lower than the set temperature, the heating function turns ON, and the fan blows warm air.

If the heater cycles but doesn't produce heat for hours:

If the temperature is set lower than the room temperature, the heater will perform only the sensing cycle and will not turn on the heating function. To have the heater turn on, always set the desired temperature higher (2°+) than the room temperature.

How to turn off the heater:

Switch to STANDBY mode or POWER OFF the heater.

Does the blower cycle use much electricity?

The blower fan runs for 60 seconds every 5 or 30 (night mode) minutes to clear residual heat and measure room temperature. This does not use much power.

Why does the blower fan keep running after I have pressed the power OFF button?

The blower fan will continue to run until the heat chambers cool down. After approximately 90 seconds, the fan will shut off automatically.

What if the heater's airflow seems to have diminished?

Please ensure the rear intake is not blocked and that the filter is clean. Follow the filter maintenance procedure to clean the filter.

Once the heater is turned on, how long will it take to heat my room?

This heater can heat a large room. However, heating time depends on variables such as room size, insulation, number of doors/windows, concrete surfaces (heat sinks), exterior door usage, and outside temperature. This is a zone heater meant to be used as a supplemental heating source only.

Can I use the heater to heat multiple rooms at the same time?

Heating effectiveness varies based on floor plan openness and room size. Customers have reported success heating multiple rooms simultaneously by placing the unit in a central room and using ceiling fans. Experiment to find what works best.

My home is not well insulated; will this heater help me?

Yes, but it may take longer to heat the room. Outside temperature also impacts heating time. Once the room reaches the desired temperature, it will cycle on and off accordingly.

Can the heater be used in a bathroom?

It is not recommended due to the high level of moisture in bathrooms.

Can the heater be used in a basement or garage?

Yes, but rooms with little insulation retain heat less efficiently. Bare concrete floors absorb heat. Placing the heater a few feet above the floor may allow for more efficient heating.

Can I use more than one heater at a time?

Yes, but ensure heaters are not on the same circuit. Each heater and appliance should be on its own circuit.

Can I use the heater and another appliance at the same time?

Yes, as long as they are not on the same circuit. This heater is considered an appliance. Do not run more than one large appliance on a single circuit breaker. Appliances like freezers, refrigerators, microwave ovens, washing machines, and dryers should not share a circuit breaker.

Can I use the heater on a job or construction site?

This heater is not designed for high dust construction environments. Using it for this purpose will void your warranty.

Can I move the heater around while it is operating?

It is not recommended. Move the heater only once the fan has completely turned off.

What is the life expectancy for the heater?

This heater uses an infrared tube rated for 20,000 hours and up, and a PTC element rated for 80,000 hours and up.

What is zone heating?

Zone heating focuses heat where people spend the most time, avoiding heating unused areas to a high temperature.

Can I use an extension cord, surge protector, or power strip with my heater?

No. The DR. INFRARED HEATER is designed to plug directly into a grounded 120V 15 Amp or higher circuit receptacle. Never use with an extension cord or relocatable power tap (outlet/power strip).

How many kilowatts per hour does the heater use?

The DR. INFRARED HEATER MODEL DR-968 uses approximately 1.35 kilowatts per hour.

What is the BTU Rating for the heater?

The DR. INFRARED HEATER MODEL DR-968 is approximately 5200 BTUs.

The power cord feels warm to the touch; should I be concerned?

It is normal for the heater's plug and cord to feel warm. However, if a plug or cord becomes hot to the touch or distorted, it may indicate a worn electrical outlet. Worn outlets should be replaced. Plugging the heater into a worn outlet may result in overheating of the power cord or fire.

I don't have a grounded outlet; can I use a cord adapter or remove the grounding plug?

NO. If you don't have a grounded outlet, contact a licensed electrician for advice. Removing or altering any part of the heater is unsafe and will void your warranty.
