LOCATING HEATER
Install heater out of traffic areas, maintaining clearances stated in figure 3. The directionof air
flow should not be restricted is by columns or machinery and the air flow shouldwipe exposed
walls rather than blowing directly on them. When more than one heater is usedin an area, the
heaters should be arranged so that the air discharge of each heatersupports the air flow of the
others to provide best circulation of warm air as indicated in figure4.

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 witha
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.

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 selection
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 0cleaned 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.
