Using the heater without a properl
grounded outlet or adapter could
result in an electric shock hazard.
The cord has a plug as shown at A in
the following figure. An adapter, as
shown at C, is available for
connecting three-blade
grounding-t pe plugs to two-slot
receptacles. The green grounding lug
extending from the adapter must be

QUESTI NS AND ANSWERS
If the heater cycles N/ FF 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 either AUTO
HIGH or AUTO LOW mode. (The factor default setting is 68 °F.) For an
example of how the heater works, let’s sa ou set the temperature for 70 °F.
Once the room has reached 70 °F, the heater switches off and the fan stops
(Note: The heater remains on STANDBY as long as ou do not POWER OFF).
As the heater remains on STANDBY, it will read the room temperature ever 5
minutes b running the fan ONLY for 30 seconds. During this process, the fan
also blows out the residual heat from inside the chamber to ensure an
accurate temperature reading of the room. If the room temperature is at 70
°F(or higher), the heater will remain on STANDBY. It will repeat this sensing
cycle, reading the room temperature, ever 5 minutes. However, if the room
temperature drops 2 degrees lower than the set temperature, the heating
function will turn the heater ON and the fan will blow warm air.
If the heater cycles but doesn’t produce heat for hours:
If the temperature is set lower than room temperature, the heater will perform
only the sensing cycle and the heater will not turn on in the heating function.
To have the heater turn on, always set the desired temperature higher (2°+)
than the room temperature, or manuall select High or Low to have instant
heat.
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 will run for 30 seconds ever 5 minutes to clear residual heat
inside the chamber, while at the same time measuring the room temperature.
This uses less than 18 watts of power to operate.
Why does the blower fan keep running after I have pressed the power
FF button?
The blower fan will continue to run until the heat chambers cool down. After a
few minutes the fan will shut off automaticall .
What if the heater’s airflow seems to have diminished?
Please ensure the rear intake is not blocked and that the filter is clean. Please
follow the filter maintenance procedure to clean the filter.
nce the heater is turned on, how long will it take to heat my room?
This heater can heat up to 1,000 square feet. Generall speaking, it takes
minutes to heat a room. Remember that with an t pe of heating process,
there are man variables such as the size of the room, how well the room is
insulated, how man doors and windows there are, the amount of bare
concrete (which acts as a heat sink with an t pe of heating), the opening and
closing of an exterior door, the outside temperature, etc. Please remember
that this is a zone heater and is meant to be used as a supplemental heating
source onl .
Can I use the heater to heat multiple rooms at the same time?
Keep in mind that heating will var based on how open our floor plan is
and the size of the rooms involved. We have heard from customers that
with the help of ceiling fans, the have been able to heat multiple rooms
simultaneousl b placing the unit in a central room. We suggest ou give it
a tr and see what works best for ou.

My home is not well insulated; will this heater help me?
Yes, but it ma take a little longer to heat the room. The outside temperature
will also have an impact on heating time. Once the room has reached the
desired temperature, it will c cle on and off accordingl .
Can the heater be used in a bathroom?
It is not recommended due to a bathroom’s high level of moisture.
Can the heater be used in a basement or garage?
Yes, but keep in mind that rooms with little insulation will not retain the heat as
efficientl . Bare concrete floors, which act as a heat sink with an t pe of
heating, will absorb some of the heat. However, placing the heater a few feet
above the floor will allow for more efficient heating.
Can I use more than one heater at a time?
Yes, but please make sure the 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 the are not on the same circuit. This heater is considered to
be an appliance. You should not run more than one large appliance on a single
circuit breaker. Your appliances, such as a freezer, refrigerator, microwave
oven, washing machine, dr er and others, should not share a circuit breaker.
Can I use the heater on a job or construction site?
This heater is not designed to be used in a high dust construction environment.
Using the heater for this purpose will void our warrant .
Can I move the heater around while it is operating?
It is not recommended to move an portable heater while it is operating. We
recommend moving the heater onl once the fan has completel turned off.

What is the life expectancy for the heater?
This heater uses one infrared tube (which is rated for 20,000 hours and up),
and one PTC element (which is rated for 80,000 hours and up).
What is zone heating?
Zone heating focuses heat where people spend the most time. After all, there
is no point in heating multiple rooms to +68 degrees when not in use.
Can I use an extension cord, surge protector, or power strip with my
heater?
No. The DR. INFRARED HEATER is designed to plug directl 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 approximatel
1.26 kilowatts per hour.
What is the BTU Rating for the heater?
The DR. INFRARED HEATER MODEL DR-968 is approximatel 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 to the touch. A plug or
cord which becomes hot to the touch or becomes distorted in shape ma be a
result of a worn electrical outlet. Worn outlets or receptacles should be
replaced prior to further use of the heater. Plugging this heater into a worn
outlet ma result in overheating of the power cord or even a fire.
I don’t have a grounded outlet; can I use a cord adapter or remove the
grounding plug?

NO. If ou don’t have a grounded outlet, contact a licensed electrician in our
area for advice. Removing or altering an part of the heater is unsafe and will
also void our warrant .
How long is the warranty?
This heater comes with a THREE-YEAR LIMITED COMPONENT WARRANTY.
