POWER INDICATOR LIGHT:
Once installed and the breaker is turned ON, the YELLOW Power
Indicator Light will glow.
This light stays on as long as power is on at the breaker, even
when the heater is off.
SETTING THE THERMOSTAT:
Press the TIMER Button continuously until the LED screen
displays "O".
1. From “OFF” rotate the knob clockwise to a higher position.
2. Pick the desired power level (I, II or III) at the Control Switch.
3. Once the room reaches the desired comfort level, rotate the
thermostat knob counter-clockwise until it clicks off.
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 cooldown.
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.

MOUNTING BRACKET INSTALLATION
Refer to
Figures 4a and 4b.
1. Locate a ceiling joist or other firm structural element or
support to mount the heater and point at desired direction
of air flow.
2. Drill a ¼” pilot hole in the ceiling joist for the screws.
3. 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).
4. Tighten the screws to secure the heater.
OPERATION
INSTALLING THE HEATER:
LOCATING THE HEATER:
Install the heater out of traffic areas, maintaining the clearances
stated in
Figure 1
above. 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
.
