Tools
Optimal airflow: As far as possible inject the air into the driest room and
extract from the most humid room to eliminate the risk of leading the moisture
through the rest of the building. The thermostat and sensor should be
protected from other heat sources or direct sunlight. They should be located
in a place with good ventilation, but not directly in the air flow from the
solar collector.
The hole: Please distinguish wooden house and brick wall, so the correct
electric drill is adopted. If it is a brick wall, use a brick wall tool and a
plastic expansion pipe. Take care not to drill into cables, power sockets,
pipes, etc. If the wall or roof is not flat, pay attention to waterproofing.
You can use polyurethane foam caulk, silicone or sealant to level it.
When installing, the outdoor air inlet must be opened downwards, and rainwater
cannot enter; any angle, if there are eaves, or other means of shelter from
the rain. A small amount of water will not burn the line, it is a low-voltage
circuit. After installation, remove the film on the aluminum alloy. It will
be ugly after sun exposure.
The thermostat is a mechanical thermostat or an LCD thermostat, and the indoor
air outlet is automatic or manual. There are different configurations and
installation methods, please refer to the actual product.
Placement: Installed facing south as much as possible. When placed 45 degrees
from due south the system also works, but with an approx. 15% lower
performance. Note that by setting up two panels, e.g. one facing east-
southeast and one south-southwest, you can take full advantage of the
available sunshine throughout the day. 
Each model can be installed in any direction as long as it is protected from rain, eg. Under the eaves. 
It is possible to use only air intakes that heat fresh outdoor air, and don’t
use the air outlet that heat indoor air. 
Activated carbon filter, filter dust, drive off odor, silencer, prevent flying
insects. Plug it in the air intake duct to the fan. It needs to be removed and
cleaned in time to avoid blocking the warm air.
Otherwise please do not use.
Do not over-tighten the No. 9 black screw, the aluminum alloy will be deformed, and the sealing strip may fall out.

The following part is just for
The temperature and humidity meter cannot be directly exposed to the sun.
Avoid placing the photoelectric switch of the air outlet directly at sunlight or incandescent lamps light. Please install the photoelectric switch facing down to avoid possible sunlight.
The following part is just for mechanical thermostat
There is no distinction for negative or positive poles. The panels are thermostatically controlled so that the fan turns off when a certain temperature is reached. It needs to be set above 15℃ for the fan to work. Thermostat installed in the room. If you want to prevent cold air from entering the room, please connect ① and ④, and then put the thermostat inside the air intake duct. When the temperature is lower than the temperature set by the thermostat, such as 12 ℃, the fan will not work.
Operation
Thermostat set value is higher than the room temperature.
Function 1 Standard: Heating outdoor fresh air. Available for all models.
Function 2 Indoor air circularly heating mold:
The distinct internal circulation can keep heating the room air. When the
outdoor temperature is too low, just open the air inlet indoor to keep heating
the indoor air. Just close the air inlet indoor to introduce and heat the
fresh air outdoor. Available for OS22/32/42. In this mode, it is recommended
that the air volume is the largest. The larger the air volume, the better the
heating effect of the whole room.
If you want to increase the heating efficiency and dehumidification effect,
please increase the wind speed, the heat loss will be reduced. Please turn
down the air outlet, if you need air going to the room with higher
temperature; Or feel too noisy. If you want to test the air temperature,
please use a thermometer. Somatosensory temperature is greatly affected by
wind speed, and cannot accurately detect wind temperature and heating effect.
Part of the reason for not working
The solar air heater don’t raise the temperature or ventilate in these
situations:
The power displays abnormal, LCD screen does not turn bright, all the value
displays 0, sometimes it shows only 4V, flickers, the voltage is insufficient.
Solution:
- The day is sunny, however the angle of sunlight is wrong. Maybe the sun is directly above or tilted too much.
- Check if the pv panel is shaded by the trees or buildings etc. Make the whole pv panel is exposed in the sunlight. Any shadows on the pv panel might impact the generation of power. If it’s overcast, the sun isn’t shining or is only shining weakly, during the night, early in the morning or late at night and when the panel is covered by snow or ice or during rain.
- Pull the wires out and try to plug it back in the thermostat. Maybe it’s a hit.
- Just for LCD thermostat. The correct clock must be set for the collector to work normally. The temperature and humidity display, or the operation of the fan and automatic air vent will have some lag. Within 10-40 minutes, the work will start when stable light is detected. It is recommended to check again after half an hour.
If the problem is still not resolved, please open the silver tape. It is possible that a connection cable has been disconnected; It could be a wire collision. Please use an electric tape to connect it back. If you need to replace the fan, please open the fan cover. The rear panel is attached with screws that can be removed. After repairing, just screw the two symmetrical screws back.
Please take photos for us to find the solution. As long as the photovoltaic panel is good, it can be repaired. If you can do a few tests that will help us determine what is wrong with that solar air heater it would be very helpful.
Repair: You can substitute the spare parts except pv panels all by
yourself with easy tools like scissors, tape, screwdriver.
Maintenance: 6 years Warranty for Oscar solar air heater: Aluminum alloy
frame, glass and photovoltaic panels are guaranteed for 6 years. Sunon fan
warrant 40000 hours. Thermostat, air outlet can be replaced free of charge
within 2 years.
Environmental requirements
Waste cartons, foam and plastic bags, please put in the designated bins.

Dear customer,
Thank you very much for purchasing our solar air collector! Are you satisfied
with our products, services, logistics and after-sales?
If you are satisfied, your comment is really important to us.
Our products also ventilate, dehumidify and purify the air. In spring and
autumn, the sun will be much better and the effect will be much better. In
addition, the temperature on the sunny side usually rises by more than 10°C
under the bright sun. Solar products are environmentally friendly and very
useful for reducing greenhouse gas emissions. Reducing the air volume can
increase the temperature and reduce the noise; increasing the air volume can
improve the heating efficiency and dehumidification effect. If you want to
test the air temperature, use a thermometer. The body temperature is greatly
affected by the wind speed, and the air temperature and heating effect cannot
be accurately detected. If you are not satisfied, please contact us, we will
improve.
Thank you very much for your support of our work!
We wish you a happy life!
