♣ Tip
· In order to be operated, the setting temperature should be higher than current temperature.
· After power On, the default mode is temperature control mode.
· During the operation if you push On/Off button, the heater is stop and the off timer fuction is
cancelled.
· The model equipped "pre-heater" is operating its heater for 1min. after burner ignition.
By this device, the oil warms up before being supplied to the burner, which improve remarkably
the ignition and inflammability.
The model equipped solenoid valve (by-pass device) makes the remaining oil returned to the oil tank.
For 10sec. from the time of burner off, the solenoid valve is operation, which makes remaining oil
returned to the oil tank, and by this device, the smell caused by unburned gas
are remarkably shrunk.

HOW TO USE
SELF-DIAGNOSIS FOR THE SAFETY DEVICE
1. AUTO CHECK FOR NOT BURNING - DISPLAY "Err"
· If not burning, it try to re-start, and if still not burning,
then Not burning lamp is ON and post fuggy is worked,
all other operation is stop.
2. SAFETY CHECKING SENSOR FOR OVER HEATING
· During the heater operation, if the inner temp is reached
to 105℃, the over-heating sensor is worked, and over
heating indication lamp is ON and all other function is
stop. (Displaying "Err")
(If time passing and the inner temp. is cool down below
the temp. which is detected by the over heating sensor,
automatically heater start to operation.)
3. AUTO CHECK FOR EXTERNAL IMPACT OR
PHYSICAL SHOCK AND INCLINATION
· Display "Err" If this heater is inclined more than 30°,
or strong external impact is applied to the heater,
tilt light is ON, post fuggy is worked, and all other
operation is stop
4. LACK OF FUEL LAMP - DISPLAY "OIL"
· If continuing operation even after display of the oil shortage
and amount of oil is reached to the below limitation level,
oil shoarge lamp is ON and post fuggy is worked and all
other operation is stop.
5. SAFETY OPERATION - DISPLAY "Er1"
· If detected fire before burner operation, post fuggy is
worked and all other operation is stop.
6. CHECK FOR TEMP. SENSOR - "Er2" DISPLAY
· If the temp. sensor which detects current temp. has
problem, display error and operation is only by Time
control operation. Display "Er2" and press On/Off button,
it go to Time control operation.
♣ Notice
· Post fuggy : For the safety purpose, ventilate out the remain
gas which is existing in burner side.
· When error message is displayed, please remove
the problem factors and press the On/Off button.
· Then, display error is disappear and lamp is off.

DAILY CHECK POINTS & ADJUSTMENT
DAILY CHECK POINTS
Soft
clothes
A

■ IN CASE OF SUDDEN STOP DURING OPERATION
· Please check if now is operating in the time control operation. If so, the heater can be rest for 5min.
· Please check if now the setting temp. is less than the current temp.
· Please check if the heater is stop by pressing On/Off switch by remote controller or front controller.
· Please check if the heater is stop by sleep timer function.
· Please check if the heater is stop by auto-self-checking.
■ AIR FLOW-OUT
In case that Electric pump so noisy and burner no ignition, main cause of the problem is air flow into the electric
pump and not distribute oil. If oil is all consumed without remaining in the tank, air can be flow into inside electric pump.
· The method to flow-out air
①Operate the heater
②When the electric pump operated, turn on the air outflow screw to counter-clockwise. And you wait till air flow out
and oil start to come out.
③When you see oil start to come out, turn off the air outflow screw to clockwise
(In case much air inside, please repeat same way 2~3times.)
