4 A. Safety Instructions I. Basic Assembly and Operation IMPORTANT SAFETY INSTRUCTIONS When using an electrical appliance, basic precautions should always be followed, including the following: READ ALL INSTRUCTIONS BEFORE USING THIS APPLIANCE WARNING: The manufacturer cannot accept responsibility for damage caused when the appliance is not used according to the instructions, or for uses other than those for which it was intended. To reduce the risk of fire, electric shock or injury: DO NOT plug the heater into any other cord connected device such as a power strip, surge protector, multiple outlet adapter, grounding adapter, outlet-type air fresheners or extension cords. Plug into a 3-prong, 120V 15 amp or higher grounded circuit receptacle only. DO NOT plug the heater into a loose fitting or broken receptacle. DO NOT alter the heater s design or you will void the warranty. DO NOT block the front or rear of the heater. DO NOT place anything directly in front of the heater. DO NOT cover the unit as this may block airflow and cause the heater to malfunction. DO NOT use the heater outdoors or in construction sites. DO NOT force the filter to dry using any alternative methods when performing filter maintenance, doing so could damage the filter. DO NOT run the power cord under carpeting. DO NOT cover the power cord with throw rugs, runners or similar coverings. Arrange the cord away from traffic areas and where it will not be tripped over. DO NOT insert or allow foreign objects to enter any ventilation or exhaust opening as this may cause an electric shock or fire, or damage the heater. DO NOT operate this heater with a damaged cord or plug or after the heater malfunctions, has been dropped or damaged in any manner. Return heater to an authorized retailer for examination, electrical or mechanical adjustment or repair. DO NOT use this heater in areas where gasoline, paint or flammable liquids are used or stored. A heater has hot or arcing parts inside. 3 This heater is hot when in use. To avoid burns, do not let bare skin touch hot surfaces. Always unplug this heater when it is not in use. To disconnect the heater, turn controls to off then remove plug from the outlet. To prevent a possible fire, do not block air intakes or exhaust in any manner. Do not use on soft surfaces, like a bed where openings may become blocked. Keep combustible materials such as furniture, pillows, bedding, clothes, curtains and paper at least 3 feet from the front of the heater and keep them away from the sides and the rear. Use this heater only as described in this manual. Any other use not recommended by the manufacturer may cause fire, electrical shock or injury to persons. Avoid the use of an extension cord because the extension cord may overheat and cause a risk of fire. This heater is for use on 120 volt grounded outlets. An adapter should not be used. This heater must be located near a socket outlet. Extreme caution is necessary when any heater is used by or near children or invalids and whenever the heater is left operating and unattended. This heater is not intended for use in bathrooms, laundry areas and similar indoor locations. Never locate the heater where it may fall into a bathtub, shower, swimming pool or other water container. Connect to properly grounded outlets only. SAVE THESE INSTRUCTIONS. Page 2

5 I. Basic Assembly and Operation B. Grounding Instructions This heater must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This heater is equipped with a cord having an equipment-grounding conductor and grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances. This heater is for use on a nominal 120 volt circuit and has a grounding attachment plug that looks like the plug illustrated in Figure B. Grounding. Make sure that the heater is connected to an outlet having the same configuration as the plug. No adapter should be used with this heater. Figure B. Grounding Grounding Grounded Outlet Grounded Outlet Box WARNING - Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the heater. If it will not fit the outlet, have a proper outlet installed by a qualified electrician. C. General Performance Keep machine and all accessories clean and in good operating condition. Clean or change filters as recommended to maintain optimum performance and efficiency. Always use genuine filters and parts, as use of other products may result in poor performance. Tacony filtration products are designed for maximum performance. Have machine checked periodically by the retailer Store machine carefully in dry area. Page 3

35 IV. Troubleshooting 1. The Airflow has been reduced Clogged Filter Possible Cause Clean or replace the filter Solution Object obstructing airflow Check the back intake for obstructions Problem with cross flow blower. Check blower and replace if necessary. 2. The heater stays on after the thermostat is turned down/the heater is blowing cool air. Possible Cause Solution 1. This is a normal function of the heater. During this time, the heater is cycling the remaining heat into the The fan will shut off on its own after the element has cooled. room and is cooling the heating element down. 3. The heater will not blow any air. The indicator light is on. Possible Cause Thermostat is set below current room temperature. The element is still heating up. The thermostat is out of calibration. The in-line thermal fuse is blown. Faulty tip switch or relay. Element is not heating up. Solution Set thermostat above current room temperature. Allow two minutes for the air inside the heater to warm. At that time the fan will begin to operate. Calibrate the thermostat according to the instructions in Section II, A, on page 7. If the heater is not warming up at all but the indicator light is on the in-line thermal fuse could be blown. Check the fuse and replace the wire harness if necessary. If the in-line fuse is still intact, check the relay and tip switch and replace if necessary. Check element. Replace if necessary. NOTE: The element used in this heater should have a life of 10 years or longer. Do not change the element unless all other components have been eliminated. 4. The programmable thermostat display doesn t light up. Possible Cause The switch is set to Standby mode. Solution Slide the On/Standby switch to On. Page 33

36 IV. Troubleshooting The heater will not turn on. The indicator light does not light up. Possible Cause Inadequete power source The circuit breaker has tripped. Solution Make sure the heater is plugged directly into an unused, grounded 120 volt, 15 amps or higher circuit receptacle. Check the breaker. If it has trippied, turn the heater off and unplug it from the power sources. Press the circuit breaker button to reset it. Plug the heater back in and turn it on. If the breaker trips a second time check the heater componatns for an electrical short. The power cord is damaged or faulty. Check the power cord for damage and continuity. Replace if necessary.
