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-LOW-

FAN-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 ashing, 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 o 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 o, the fan will continue to run to cool down the unit and there will be a

90 seconds countdown on the digital display.

WARNING: The installation of main power supply is highly recommended to be

carried out by a certied electrician. The installation process involves working with

electrical components, which can be dangerous and potentially life-threatening if

handled incorrectly.

1. With the power o at the breaker,

remove all screws from the bottom lid

for access to the electrical section of

the heater.

2. Attach exible cable through a knock-

out in the side of the heater following

NEC and local codes, See Figure 6 and

SPECIFICATIONS for recommended

wiring and circuit breakers.

NOTE: For certain applications, conduit

may be required. See Figure 6. Check local

electrical codes. If you run the wiring in

conduit and wish to be able to turn the

heater be sure to purchase enough exible

conduit to allow the heater to be turned.

3. Pull enough wire into the heater and

connect to wire to the Power Block

located in the electrical area of the

heater. See Figure 7.

4. Be sure to torque all terminal screws

and power block lugs tight, see

SPECIFICATIONS and NEC/local

codes, for required torque values,

failure to do so can overheat the

power blocks.
