  7. Insert the power supply cable through cable clamp, allowing at least 6’’ (152cm) of leads to extend inside the back box. Connect the black and white lead wires of the disconnect switch to the supply wire leads using wire connectors.
  8. Ground the switch bracket by connecting the supply ground lead wire to the green ground screw located outside the left of the switch bracket.
  9. Secure the disconnect switch bracket in place by tightening the screws.

FOR EXISTING CONSTRUCTION

  1. Carefully mark and cut a rectangular hole measuring 14 5/8” (371 mm) wide by 18 ½’’ (470 mm) tall at the desired mounting height. One edge of the hole must be cut along the edge of a stud. Remember to follow minimum clearances, see “Safety Instructions”.GLOBAL-INDUSTRIAL-246743-Fan-Forced-Wall-Heater-FIG-3

  2. Run a power supply cable into the area above the top of the wall opening. All wiring must be in accordance with National and Local electric codes. Refer to “Specifications” for correct wire size.

  3. Remove disconnect switch bracket by loosening the two screws on the right side.

  4. Install a cable clamp in the “knockout” in the top of wall back box.

  5. Insert power supply cable through cable clamp, allowing approximately 6” (152cm) of cable length to remain inside the back box to facilitate connections.

  6. Place the back box into a wall opening with the bottom and sides of box flush with the finished wall surface. The top flange of the back box should protrude approximately
    ½’’ (12.7mm) from the finished wall surface.

  7. Push thermostat knob onto thermostat shaft.

The wall heater is manufactured and shipped at the highest rated wattage, see “Specifications”. Full wattage heater can be converted to half-wattage through the following steps

GLOBAL-INDUSTRIAL-246743-Fan-Forced-Wall-Heater-FIG-5

  1. Remove the red jumper wire as shown in Figure 4 (next page), and discard.
  2. To permanently make the heater half-wattage, cut the male terminal spade, being careful not to damage the cold pin and discard.
  3. Mark the wattage of the heater on the white label inside the back box.

NOTE: Full wattage heater can be converted to half wattage by removing the red jumper wire connecting the top and bottom element terminals in the field or at the factory.

MAINTENANCE AND OPERATION

  1. Heater must be properly installed before operation.
  2. Rotate thermostat knob fully clockwise to reach the maximum heat setting.
  3. Wait at least 2 minutes, the fan control will not allow the fan to run until the heating element is warm.
  4. If fan does not come on after extended period of time, check to see if heating element is on and check wiring.
  5. Allow heater to continue operating until desired room temperature is reached, then turn thermostat knob counterclockwise until thermostat clicks off. The fan will continue operating until the element cools.
  6. Readjust thermostat settings until room remains comfortable temperature. Turning the thermostat clockwise will increase the duration of heat production while turning it counterclockwise will decrease the duration.

NOTE: It is advised to leave the thermostat fully clockwise when heating room from cold temperatures.

CAUTION: Operation of the manual reset safety thermal limit control is an indication that the heater has been subjected to some abnormal condition, It is recommended that the heater be checked by a reputable electrician or repair service to ensure the heater has not been damaged.

HOW TO MANUALLY RESET OVER- TEMPERATURE LIMIT

This heater features an over-temperature safety control that will turn off the heater if it overheats. This control is located on the fan panel assembly between the element and fan blade and marked “reset”. The red reset button can be seen through the front grille when the heater is installed. To reset, allow the heater to cool, then push the red button that is visible through the hole in the fan panel. The heater should immediately return to normal operation.

CAUTION: Do not continue to attempt to use the heater if the safety control repeatedly operates after being reset. To do so could permanently damage the heater or create a fire or safety hazard.

WARNING: Do not tamper with or bypass any safety limits inside the heater.

BASIC UPKEEP

WARNING

  • All servicing beyond simple cleaning that requires disassembly should be performed by qualified service personnel.
  • Before performing any maintenance or service, disconnect all power coming to heater at main service panel and check that the element is cool. This must be done to ensure a reduced risk of fire and electric shock or personal injury.

It is important to keep this heater clean, just like any heater. Your heater will give you years of service and comfort provided you take care of it. To ensure efficient operation and a long service life, adhere to the simple instructions that follow

  1. When the heater is cool, use a vacuum cleaner with a brush attachment to remove dust and lint from exterior surfaces, including the grille openings.
  2. With a damp (not wet) cloth, wipe dust and lint from grille and other exterior surfaces.
  3. Return power to heater and check to see if it is operating properly.

CAUTION: At least annually, the heater should be cleaned and serviced by a qualified service person to assure safe and efficient operation. This should include the removal of the grille and, as necessary, the heater from the back box to clean dust and residue from the unit. After completing the cleaning and servicing, the heater should be fully reassembled and checked for proper operation.
