WARNING: To reduce the risk of fire, do not store or use gasoline or other flammable vapors or liquids in the vicinity of the heater.
CAUTION: High temperature, risk of fire, keep electrical cords, drapery, furnishings, and other combustibles at least 3 feet (0.9 m) from the front of the heater.
Heater Location And Clearances

The heater is intended for horizontal use on a hard floor, tabletop, desk or on the shelf, and the like. The discharge air should wipe the walls without blowing directly on them (Figure 2).
Ensure the air discharge is parallel to or away from walls.
! NOTE: To prevent personal injury always use a licensed electrician to install new outlets or circuits.
CAUTION: When turning and/or tilting the heater do not block the exhaust opening.
Use Of Support Stand (EMC4240 only)
The pre-installed support stand can be swiveled out to allow an upward angle for the air discharge. When in a down position, the heater should be placed on a flat surface such that it will be stable and not fall over (Figure 3).

Operation

WARNING: This heater must be properly installed before it is used.
SETTING THE THERMOSTAT.

  1. Before connecting or disconnecting the plug, turn the knob fully counterclockwise.
  2. The heater is equipped with a thermostat. To adjust the temperature to your individual requirements, turn the thermostat control knob clockwise all the way to turn the heater on. The yellow power light will illuminate (Figure 4). When the room reaches the desired temperature, turn the thermostat knob counterclockwise until you hear a click. Leave in this position to maintain the room temperature at this setting. For additional heat, turn clockwise until you hear a click again and the heater will turn on. To shut the heater off turn the thermostat knob counterclockwise all the way. The yellow power indicator light will turn off.

WARNING: Should the heater overheat, an automatic cut-out will turn the heater off and it will not come back on without being reset. It can be reset by unplugging the unit and waiting 5 minutes before plugging the unit back in.
If you need to continuously reset the heater, unplug the unit and contact a licensed electrician. DO NOT USE THE HEATER UNTIL THE CAUSE OF THE PROBLEM IS DETERMINED AND FIXED.

Maintenance

WARNING: Disconnect power before attempting any maintenance or cleaning to reduce the risk of fire, electric shock, or damage to persons.
CAUTION: Allow at least 30 minutes for the heater to cool before attempting any maintenance or cleaning.
!NOTE: This heater should not be operated with an accumulation of dust or dirt on or in the unit, as this can cause a build-up of heat and eventual damage. For this reason, the heater must be inspected regularly, depending upon conditions and at least at yearly intervals. To clean the exterior surface, use a solution of water and mild detergent, apply with a damp sponge. Wipe dry with a dry cloth. DO NOT plug the heater into the outlet until it has dried thoroughly.
