OPERATION
Figure 1
The manual controls for the electric replace are located on
the right end of the unit (Figure 1).
A. On/Off Switch
The On/Off Switch supplies power to all replace functions.
When the switch is in the “I” position, the unit is on. When
in the “O” position, the replace is off.
B. 3-Position Switch
The 3-Position Switch changes the mode the replace
operates in and has three (3) positions: “MANUAL”; “OFF”;
and “REMOTE”.
When in “REMOTE” mode, the replace’s three levels of
operation are controlled by the ON and OFF buttons of the
remote control.
In “OFF” mode, power to all functions is cut off.
In “MANUAL” mode, the replace’s three levels of
operation are controlled by the Manual Control Buttons.
C. Manual Control Buttons
The Manual Control Buttons operate the replace levels
sequentially (from off): ames only; to ames and low heat;
to ames and high heat.
The level is increased every time the “I” button is pressed,
and the replace can be turned off at any point by pressing
the “O” button.
Resetting The Temperature Cutoff Switch
Should the heater overheat, an automatic switch will turn
the heater off and it will not come back on without being
reset. The temperature cutoff switch can be reset by
unplugging the unit, waiting ve (5) minutes and plugging
the unit back in.
CAUTION: If you need to continuously reset the heater,
unplug the unit and call Dimplex customer service at
1-888-DIMPLEX (1-888-346-7539).
Remote Control
The replace is supplied with a radio frequency remote
control. This remote control has a range of approximately
50 feet (15.25 m), it does not have to be pointed at the
replace and can pass through most obstacles (including
