MAINTENANCE

The superior quality and design of this heater will provide years of trouble-free performance. Each year the heater should be checked and cleaned for lint and/or dust accumulation. King recommends using a soft bristle brush and vacuum to knock off contaminates. The motor is permanently lubricated and requires no oiling.

Operating voltage cannot exceed 5% of rated voltage. Operating heater above listed voltage ratings voids all guarantees and warranties.

INSTALLATION

Turn off power source supplying the heater before attempting installation, maintenance, or repairs. Lock or tag circuit breaker or fuse panel door. Failure to do so could result in serious electrical shock, burns, or possible death.

1. After removing the heater from the carton, check to make sure the heater has not been damaged in shipment.
2. Remove the grill by loosening and removing the two screws on the side of the front panel. Remove fan heater assembly.
3. Remove one 7/8" knock-out and feed the supply wire into the wall box using an approved electrical fitting to prevent chafing of the supply wires.
4. Install the wall box a minimum of 6" from vertical side walls. The Slim Line heater is approved to be mounted at floor level although we recommend mounting it 4" above the floor. This will help the heater run cleaner, thus require less maintenance.
5. Secure the wall box to 2x4 studs (Use molly bolts if studs cannot be located) using the 4 holes provided in the back of the surface box.
6. Select heater wattage (see diagram). King recommends the installer indicate the selected heater wattage by circling the wattage listed on the nameplate.
   To prevent the heater from being rewired to a higher wattage, cut the push- on ¼" female terminal off the disconnected wire (orange, blue or yellow).
   Tape all exposed wires. By disabling the heater in this manner there is no need to size the circuit beyond the actual connected load. (For future flexibility to increase wattage, size circuit for the maximum 2250 Watts per heater for 208/240 Volt, 1500 Watts per heater for 120 Volt). Attach the field grounding wire to green screw or pigtail
7. Reinstall heater assembly at top of wallbox with mounting screw. Connect supply and ground wires. (see diagram)
8. Replace the front grill and secure with the two screws provided. The top first louver in the grill must be open into and between wall can and top of heater for proper circulation of air.
9. The installation is now complete and the heater is ready to be energized for use.

FIELD WIRING – 120/277 VOLT:

1. Connect power supply L1 (white neutral wire) to white heater wire.
2. Connect power supply L2 (black hot lead) to black heater wire.
3. Connect ground wire to green wire on wall can.

FIELD WIRING – 208/240 VOLT:

1. Connect power supply L1 (hot lead) to a black heater wire.
2. Connect power supply L2 (hot lead) to a black heater wire.

EXPLODED VIEW

This heater includes a manual reset SLP thermal protector with a self-hold feature. If the heater shuts off in the on position and the room temperature is below the highest thermostat setting, immediately disconnect the power to the heater at the circuit breaker. Inspect for any objects on or adjacent to the heater that may cause high temperatures. After inspecting the heater, keep the power to the heater off for 10 minutes to reset the SLP thermal protector. If the SLP thermal protector shuts the heater off again, immediately turn the heater off at the circuit breaker and inspect the heater for possible fan motor failure or dirt and lint on the heating element. Repeat the starting procedure.

WARNING

It is extremely important to verify the electrical power supply is the same voltage as the heater being installed. 240 and 120 Volt heaters are not interchangeable. Powering a 208/240/277 Volt unit with 120 Volt supply wires will reduce heater output by approximately 75%. Powering a 120 Volt unit with 208/240/277 Volt supply wires will destroy the heater and voids all guarantees and warranties.

Keep electrical cords, drapery, furnishings and other combustibles at least 3 feet (.9m) from front of the heater and away from side and rear. Do not block the heater in any manner. Can be installed w/zero to floor and no closer than 6 inches to the open edge of a door and adjacent wall. Never paint the heater grill.

Turn off the power source supplying the heater before attempting any installation, maintenance or repairs.
Lock or tag circuit breaker/fuse panel door. Failure to do so could result in serious electrical shock, burns or possible death.
