LOCATING HEATER

Install heater out of traffic areas, maintaining clearances stated in figure 3. The direction of air flow should not be restricted is by columns or machinery and the air flow should wipe exposed walls rather than blowing directly on them. 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 in figure 4.

INSTALLATION

Hardware needed
You will also need the following hardware, which can be purchased from your local hardware store or electrical supply store:

• Electric wire in the adequate gauge and length for your application.
• Proper size fuse or breaker for your heater’s amperage.
• Proper wire connectors for your application.
• Fasteners appropriate for your application that are strong enough to hold the unit.

MOUNTING THE HEATER ON THE CEILING
Refer to Figures 5a and 5b.

1. Locate a wood stud in the wood ceiling joist. If you cannot locate a wood stud, you have to install a wood piece on the ceiling as this heater must be securely fastened.
2. Remove the mounting bracket from the heating unit by loosening bracket screws with a wrench and slipping the handle off over the screw heads.
3. Place a washer on screws before inserting through the holes in the mounting bracket and screw them securely into a ceiling joist.

NOTE: If you want to swivel the heater either to the right or left adding a washer to both sides of the bracket is recommended. A longer lag bolt may be required to properly secure the unit. See Figure 5a.

HANGING THE HEATER

1. Lift the heater up and into the mounting bracket.
2. Align the bracket screws with the keyhole slots in the mounting bracket.
3. If the heater is to be tilted it must be positioned in the keyhole slots – see figure 6.
4. Tighten the bracket screws with a wrench so the unit is securely suspended at horizontal or vertical level.

     
USE BOTTOM KEYHOLE SLOTS IF HEATER IS TO BE TILTED DOWN

OPERATING INSTRUCTIONS

Note: After setting an external thermostat to control the heater, the power selection & timer switch on the remote will be the only working function on the heater itself.

Control Panel

Figure: 14

Figure: 15

Once the room temperature reaches the set point, the heater will automatically stop running. After each operation for 5 seconds, the LED displays the current Timer Power !Power Timer room temperature.

Instructions in Normal mode (temperature controlled by built-in thermostat)

Power button
You can use the power button as the Power switch.
The power button is also used to change the heating output between low & high (L/H); the LED will display “L” or “H” accordingly
Model HA24-50EB: Low (L) →3000W; High (H) →5000W

Temperature selection
Press the “F/℃” button to change the temperature displayed between Fahrenheit and Celsius.
Press the “+” or “-” button to set the desired temperature between 5 ℃ and 35 ℃.
Hold down the “+” or “-” button to speed up the selection process.

Timer selec tion
Use the “Timer” button to set the operating time of your heater, from 1 hour to 24 hours. With each press of the “Timer” button, the timer will increase by 1 hour on the LED screen.

TO PROTECT THE HEATING ELEMENT
The heater includes a fan delay function to prevent risk of overheating. When turning the heater off, the unit will close the heating element first and then the fan will continue working for 90 seconds to dissipate residual heat.

THERMAL CUT-OUT
The heater will automatically turn off when parts of it overheat. When this happens, the red indicator will turn on. The heater will turn ON again and the red indicator will turn off when the unit cools down back to normal levels, but the reason of the overheating must be determined and corrective action taken before further operation.

THE HEATER MUST STOP WORKING WHEN THE CAUTION INDICATOR IS GLOWING RED.

NOTE: When the thermal cut-out is activated, the caution indicator will turn red. In this case, immediately turn the heater OFF and inspect for any objects on or adjacent to the heater that may cause high temperatures. Let heater cool off completely before turning on again.

MAINTENANCE INSTRUCTIONS

1. Before cleaning, make sure the power has been turned off at the circuit breaker panel and the heating element of the heater is completely cool.
2. To maintain the appearance of the heater, it need only be wiped over occasionally with a dry duster. During the summer months, or at other times when the appliance is not in use and is completely cold, it can be cleaned by wiping it with a damp cloth. Do not let water drip inside the heater.
3. Do not use abrasive clearing powders or furniture polish to clean this appliance. Do not use chemical or abrasive products, metallic scourers and similar items; they may deteriorate the surface.
4. All servicing should be performed by qualified service personnel. Do not try to repair the heater yourself.
