OPERATING INSTRUCTIONS

OPERATION AND TEMPERATURE SETTING

1. This heater is designed to maintain a comfortable room temperature. Always operate the heater in the upright position following all instructions and recommendations listed in this manual.
   When the heater is turned on by pressing the POWER button, it will operate on HIGH setting (7,500W) continuously. The LED display panel will show the ambient temperature. Press the MODE button on either the unit or remote to change the heat setting to LOW (6,250W). The fan will start running about 10 seconds after initial start to push the heat out. The sequence is HIGH-LOWFAN- ONLY. To  operate the unit on FAN ONLY setting, press the MODE button again. In FAN ONLY mode, the LED display panel will show FA to indicate the heater is in FAN ONLY mode. From FAN ONLY mode, pressing the MODE button will make the heater operate in HIGH setting again, and the ambient temperature will appear on the LED display.

2. The temperature setting can be adjusted between 45°F (7°C) to 95°F (35°C). To change the temperature, press the TEMP+ or TEMP – buttons on either the unit or the remote. (See Figure 2).

3. The temperature display will blink while it is being adjusted. When the desired temperature is reached, it will take about 5 seconds to accept the setting. Once the display stops flashing, the room temperature will reappear on the LED screen to indicate the desired temperature is set.

4. In any temperature mode, the unit will stay in that mode, cycling on and off to maintain the set temperature. The heater will reach the set temperature faster in HIGH setting.

5. The heater can be turned OFF by pressing the POWER button. Once the unit is turned off, the fan will continue to run to cool down the unit and there will be a 90 seconds countdown on the digital display.

TIMER FUNCTION:

The Timer function allows you to set the length of operation from 1 to 12 hours.
Each time the TIMER button is pressed the length of operation will increase 1 hour. The duration the timer is set for will be displayed on the LED screen in hour increments.
TO TURN THE TIMER FUNCTION OFF: Press the TIMER Button continuously until the LED screen displays “O”.
NOTE: The timer function is not an excuse to leave the heater unattended.
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.
FAHRENHEIT OR CELSIUS DISPLAY:
To switch the display between Fahrenheit and Celsius, press the °F/°C on either the unit or the remote.

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.

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.)
