How to install
1. Solar air heater can be mounted on outside of the wall or on top of the roof. Secure the
product in a place where it can have the best exposure to sunlight. And there is no shadow
will cast onto the product. So that product can work with max efficiency.
2. Drill a hole on the wall/roof to allow the pipe to pass through. Follow below steps:
- Use the pipe to mark two circles on your desired position. The circles should be slightly
bigger than the diameter of the pipe itself.
- Drill two holes where the mark is made.
- Measure the thickness of your wall, and cut the pipe to the length that matches the
thickness. Please note that pipe #2 should be longer, because its flange is secured deeper
into the product.
3. Secure both flanges onto the air inlet and outlet at back of the product with provided screws.
Remember to put the silicon rubber sealer as per diagram in the following page.
4. Secure both pipes onto flange. Longer pipe is put into the deeper flange.
5. Secure lead wire coming out of the solar air heater alongside the pipe with tapes.
6. Secure product on the outside wall or roof in a way that the both pipes can pass through the
holes.
7. Secure diffuser onto the pipe at the inside end of the wall/roof. Remember to pull the lead wire
out.
8. Seal the gap between the wall hole and the pipe.
9. Secure the thermostat besides the diffuser, and connect the lead wire coming from solar air
heater to thermostat. Connect the red wire to terminal 2, and the black wire (or blue wire) to
terminal 3. Turn the knob to your desire temperature, the DC fan in the solar air heater will stop
blowing hot air, when the room temperature is higher than the set temperature.
