If you find an obstruction, turn the product OFF and UNPLUG THE PRODUCT. Have the product serviced by a qualified individual. 4. Check for tripped thermal protector. Motor and heating element do not operate. Wait 10 minutes for product to cool. Push reset button. See Thermal Limit Switch below. THERMAL LIMIT SWITCH If product is used in temperatures below 75° F (28.9° C), the limit switch should not require resetting unless there is a malfunction. If a malfunction does occur, have the product serviced by an authorized service center. Resetting Thermal Limit Switch 1. Unplug product. 2. Allow product to cool. 3. Turn product upside down. 4. Remove plug on bottom. 5. Insert provided plastic push rod through hole and guide to small red button on thermal limit switch (see Figure 5). A flashlight will improve visibility. 6. Lightly push red button to reset switch. Air Intake Openings Access to Thermal Limit Switch Figure 5 -Resetting Thermal Limit Switch Push Rod 115423-01A TROUBLESHOOTING Continued 7. Replace removed plug in hole. Perform a trial operation. 8. If repeated resetting of the thermal limit switch is required, have the product serviced by an authorized service center. OBSERVED FAULT Tubular heating element heats up but no rush of warm air is felt at outlet vents Rotate fan by hand to determine if fan rotates easily Fan is difficult Fan rotates easily to rotate by hand 1 Fan or motor 3 Open motor coil obstructed 2 Dry motor bearing Test Procedure 1. Fan or Motor Obstructed Remove obstruction. Clean heater. 2. Dry Motor Bearing If the fan is difficult to turn, then motor bearings are defective. Bearings are permanently lubricated, therefore motor should be replaced. 3. Open Motor Coil Disconnect motor wires (black and white). Attach the ohmmeter leads to the motor wire terminals. Using the 0 to 200 ohm scale, measure the resistance of the motor coil. If the resistance is not approximately 6.0 to 6.4 ohms at 73° F, the motor is defective and should be replaced. Note: Resistances may vary due to motor temperature. Figure 6 -Testing Motor OBSERVED FAULT Motor starts and runs but cool air is felt Does tubular heating element heat up? No Yes WARNING: WARNING: Hot Surface! Hot Surface! 1 Look for defective 3 Check for blocked tubular heating air intake openings element 2 Open tubular heating element Test Procedure 1. Look for Defective Tubular Heating Element After approximately 2 minutes the tubular heating element should glow a dull red when placed in a dark area. 2. Open Tubular Heating Element Disconnect element wires (black and white). Attach the ohmmeter leads to the element wire terminals. Using the 0 to 200 ohm scale, measure the resistance of the element. If the resistance is not 8.5 to 11 ohms at 73° F the element is defective and should be replaced. Note: Resistances may vary due to element temperature. 3. Check for Blocked Air Intake Openings Check for blockages around vent openings at bottom of heater (see Figure 5, page 6). Figure 7 -Testing Heating Element 115423-01A REASSEMBLY POINTS Because this is an outdoor product where the control of water is important, the following steps for assembly must be followed. 1. The closed cell foam gasket must seal the hex shaped pan to the inside of the plastic housing (see Figure 8). The seal is to be completely even in the corners of joined parts. 2. The tubular heating element rubber sealing washers must be against the top surface of the steel pan and under the brass flat washers as shown in Figure 9. Nuts on opposite side of pan must be tightened 1/2 turn past finger tight. 3. Apply a SMALL drop of thread locking sealant (rated to 300° F, such as Loctite Thread Locker Blue) to each of the thermal rese switch mounting screws (see Figure 10 Torque screws to 6 to 9 inch-pounds. 4. The tip switch cover must isolate tip switch from metal base as shown in Figure 11. 5. To complete grounding of heater, all groun wires must be fixed with screws as originall assembled by the manufacturer. Additionall internal tooth washers must be against the ste pan and under nuts as shown in Figure 12, fo the tubular heating element. 6. No wires should be seen through openings in bottom of heater (see Figure 13).

Tubular heating element must be flush against bracket (see Figure 14). This centers the element to the center hole in metal pan. 8. Fan must be located with set screw at back of and on flat of shaft (see Figure 15). 9. Heater is equipped with heat reflective tape. If loose or damaged, replace tape as shown in Figures 16 and 17. Tape edge should touch top of louver openings. Figure 14 -Heating Element and Bracket F...
