SETTING THE THERMOSTAT:
Press the TIMER Button continuously until the LED screen displays “O
- From “OFF” rotate the knob clockwise to a higher position.
- Pick the desired power level (I, II or III) at the Control Switch.
- Once the room reaches the desired comfort level, rotate the thermostat knob counter-clockwise until it clicks off. Heater will cycle on and off to maintain room temperature.
CAUTION LIGHT:
The heater has a Thermal Cutout Switch. If there is an overheat situation this switch will shut off the heater.
Once this happens the RED Caution Light will glow, indicating and overheat condition. Turn off the heater. Turn off power at the circuit breaker and let the heater cool down
Determine the cause of the overheat situation and correct. Once cool, restore power to the heater at the breaker and resume operation of the heater.
NOTE: Heater will cycle on and off to maintain room temperature. The first time you operate the unit, it may smoke slightly. This is due to residual cleaning agents used to clean the element when the heater is manufactured. This is normal and does not indicate a problem with the unit. This condition will stop after the heater has been in operation for a few minutes.
INSTALLING THE HEATER
LOCATING THE HEATER
Install the heater out of traffic areas, maintaining the clearances stated in
Figure 1.
The air flow from the heater must not be restricted or obstructed by any items
in the room. When more than one heater is used in an area, the heaters should
be arranged so that the air discharge of each heater supports the air flow of
the others to provide best circulation of warm air, as indicated below in
Figure 3.
MOUNTING BRACKET INSTALLATION
Refer to Figures 4a and 4b.
- Locate a ceiling joist or other firm structural element or support to mount the heater and point at desired direction of air flow.
- Drill a ¼” pilot hole in the ceiling joist for the screws.
- Place the screws and washers as shown in the Figures 4a or 4b. Fig. 4a: For Single-Screw Mounting (center bracket hole only). (If you want to swivel the heater, a longer Lag bolt may be required to properly secure the heater, not included.) Fig. 4b: For Double-Screw Mounting (both off-center holes are used).
