WARNING
TO PREVENT HAZARD OF FIRE OR ELECTRICAL SHOCK, DO NOT INSTALLWITHOUT BACK BOX.
CAUTION
TO PROVIDE FOR SAFE OPERATION, THE FOLLOWING CLEAR­ANCES MUST BE MAINTAINED. WALL MOUNTING: • MINIMUM FOUR (4) INCHES (102MM) TO FLOUR • MINIMUM TWELVE (12) INCHES (305MM) TO ADJACENT WALLS • MINIMUM THIRTY SIX (36) INCHES (915MM) TO CEILING CEILING MOUNTING: • MINIMUM TWELVE (12) INCHES (305MM TO ANY WALL
CAUTION
THE HEATER IS HOT WHEN IN USE. DO NOT INSTALL THE HEATER BEHIND DOOR, BEHIND TOWEL RACK, IN CLOSET, WHERE CURTAINS OR DRAPES COULD TOUCH OR BECOME SCORCHED BY HEATER, OR WHERE AIRFLOW TO HEATER MAY BE OBSTRUCTED. KEEP ELECTRICAL CORDS, BEDDING, FURNI­TURE AND OTHER COMBUSTIBLES AWAY FROM HEATER.
GENERAL
The heater is designed for recessed installation in 2” X 4” (50 mm X 101 mm) stud or larger wall sections using the wall box provided. The heater may also be surface mounted by using the Surface Mounting Frame, Model SWHSM or semi-recess mounted by using a SWHS1 (for 1” (25 mm) recess frame) or a SWHS2 (for 2” (50 mm) recess frame). All three accessories are ordered separately. The heater may be wired with stan­dard building wire (60°C). Refer to specification chart (see pg. 4) for cor­rect supply voltage and wire size.
NOTE: The optimum mounting height for this heater is 18" to 24" (450 to 600 mm) from floor to bottom of back box. Do not install closer than 4”(101 mm) from the floor.
For surface or semi-recess mounting, consult Installation Instructions packed with SWHSM, SWHS1, SWHS2.
INSTALLATION OF BACK BOX IN NEW CONSTRUCTION
NOTE: If the finished wall surface is already up, follow instructions for
“INSTALLATION OF BACK BOX IN EXISTING CONSTRUCTION”.
1. Determine which side of the back box is to be mounted against a stud and bend the tabs at the rear corners out 90 degrees so that the back box will be square with the stud after installation. (See Figure 1).
2. Remove one of the knockouts on socket side of the back box and install a cable or conduit connector.
3. Positionback box against sideof studsandsecureusing nailsorscrews as shown in Figure 1.
NOTE: The back box must be installed with the front edge flush with the finished surface.
4. Run power supply cable through the connector, leaving about 8” of wire inside the box.
5. Connect thesupply cableground wiretogreen ground screwprovided.

NOTE: Lead holes for a #8 sheet metal screw have been provided in the sides of the back box.. After the finished wall or ceiling has been put up, drive a # 8 sheet metal screw (recommended 1” long) through the side of the box not mounted to the stud. This will prevent the back box from pulling out when installing the heater assembly. (See Figure 1)
INSTALLATION OF BACK BOX IN
EXISTING CONSTRUCTION
1. Carefully mark and cut a holemeasuring 9-3/8" (235mm) wide by 11­1/8" (283mm) long. One edge of the hole must be cut along the edge of a stud.
CAUTION
AN ELECTRICAL SHOCK, FIRE OR WATER DAMAGE COULD RESULT IF WIRING OR PIPING IS DAMAGED DURING CUTTING. MAKE SURE ALL WIRING AND PIPING ARE CLEAR OF AREA BEFORE CUTTING.
2. Proceed to No. 1 through 5 (Installation of Back Box in New Construction).
FIELD CONVERSION FOR LOWER WATTAGE RATING
NOTE: Refer to specification chart for lower wattage ratings which are
available. To convert heater to lower wattage rating, completely remove red jumper
wire from both heating elements (See Figure 2). Discard this jumper. Be sure remaining wires are securely connected.

CAUTION
DO NOT USE A REMOTE THERMOSTAT WITH THIS HEATER. BUILT IN THERMOSTAT CYCLES THE HEATING ELEMENT ONLY. FAN DELAY CONTROL AUTOMATICALLY TURNS FAN ON AND OFF, AND PROVIDES A FAN DELAY OFF FEATURE TO REMOVE RESIDUAL HEATAFTER THERMOSTAT HAS TURNED HEATING ELEMENTS OFF. WIRING OF HEATER IN ANY MANNER WHICH DEFEATS THE FAN DELAY OFF FEATURE CAN RESULT IN OVERHEATINGAND PERMANENT DAMAGE TO HEATER,AND WILL VOID THE WARRANTY.
INSTALLATION AND WIRING OF HEATER / FAN ASSEMBLY
1. Following wiring diagram (Figure 3) connect supply wiring to heater lead wires in back box.
NOTE: For 120 and 277 volt heaters connect the white neutral supply lead to the heaters white pigtail lead, and connect the black supply lead to the heater black pigtail lead. For 208 and 240 volt heaters change the color of the heaters white pigtail lead to black by wrapping with black electrical tape. (Most electrical codes require the supply leads to be con­nected to black leads). Then connect the two black supply leads to the two black receptacle leads.
2. Secure supply ground wire under green ground screw in back box.

CAUTION
BE SURE ALL WIRING IS SECURELY ROUTED AWAY FROM FAN AND ELEMENT.
4. Fit heater/fan assembly into back box and secure in place with (2) screws providedthroughthe center slots in the fan assembly.
NOTE: Use the screws provided by the factory to install fan deck to the back box.

7. It may be necessary to readjust thermostat a time or so until exact comfort level is attained. Rotation in the clockwise direction will increase the amount of time the heater will pro­duce heat. Rotation in the counterclockwise direction will reduce the amount of time the heater is on.
NOTE: For best results, the heater should be left “ON” constantly during the heating season as the thermostat, whenproperly set, will maintain the desired temperature. In the full counter-clockwise position the heater will remain off until the room temperature drops well below freezing.
AINTENANCE AND CLEANING
M
Your heateris designed for years of trouble-freeoperation and requires no specialmaintenance other than occasionalcleaning. The motor is perma­nently lubricated.
Once each year, the heater should be cleaned to remove dust and other foreignmaterial which has collectedduringthe heatingseason, as follows:
1. Turn power off at main switch.
2. Remove thermostat knob and grille.
3. Use vacuum cleaner with brush attachment to remove dust and dirt that has accumulated in heater (especially around element and fan blade). Do not use water or any cleaners to clean heater compo­nents.
4. Replace grille and thermostat knob.
5. Wipe grille clean with a damp cloth. DO NOT use waxes or any cleaners that leave a residue since these may discolor during heater operation.
6. Turn the main line switch on at the switch panel to restore power to heater. The heater is now ready for another season of operation.
OPERATIONAL NOTICE
Your heater is equipped with an automatic reset high limit control that will automatically turn the heater off to prevent a fire if the heater over­heats. Should this occur, the indicator light will illuminate and will contin­ue to shine until the limit resets.
INSTALLATION OF FRONT COVER (GRILLE) AND
THERMOSTAT KNOB
1. Attach grille bracket with screw provided in the top part of the back box as shown in Figure 4.
2. Mount top portion of the grille over the grille bracket and push down until grille is secure.
3. Insert screw through bottom of grille louver to mounting hole and tighten screw.
4. Fit the thermostat knob on to the thermostat shaft and push into place.
HEATER CHECKOUT AND OPERATION
1. After heater is completely assembled, push the disconnect switch to the “on” position and rotate thermostat knob coun­terclockwise until control stops. This is the minimum heat setting.
2. Turn power supply to heater “ON” at main switch panel.
3. Heater should not operate. If it operates, disconnect power and re-check wiring.
4. Rotate thermostat clockwise until it stops (maximum heat setting) and wait at least 2 minutes. Fan control will delay fan coming on until element is warm.
5. If heater and fan do not come on, disconnect power and
6. Allow heater to continue to operate until room temperature
IF FAN SHUTS OFF IMMEDIATELY, THERMOSTAT WIRING IS INCORRECT AND MUST BE CHANGED. FAN MUST DELAY SHUT­TING OFF TO EXPEL RESIDUAL HEAT TO PREVENT PREMA­TURE AGING OF INTERNAL HEATER COMPONENTS THAT COULD LEAD TO A HAZARD OR PREMATURE FAILURE.
