The outdoor unit should be horizontal. This is important for the correct distribution of the oil in the dry lubrication unit. Secondly, the outdoor unit should have a solid base. There should be a power cut within 3 feet of the outdoor unit. Thirdly, the outdoor unit should be about a foot away from the house. This is to allow for proper circulation of air through the condensing unit. Without proper airflow, the unit will have a higher operating pressure and thus consume more electricity.

1. The copper pipe connection between the indoor and outdoor units can easily break, which can lead to poor circulation
2. If you pack the exposed copper pipes incorrectly, there will be some pipes which can lead to clogging of the cooling system
3. if you do not vent the unit after assembly it can also lead to poor cooling and the risk of ice
4. If you add too much refrigerant, it can burn out the compressor. However, the cooling effect is very poor but too little is added.

1,To check if the fan, motor and other electrical equipment are in normal condition and bear heavy oil regularly, please check and adjust the tight fan V-belt regularly.
2,Clean the breakwater, heater and cooler regularly. And check or replace the nozzles (once every six months). One more thing is to clean the spray area water tank and water filter every fortnight
3. You should replace a filter when its resistance exceeds 0.15kPa (H20 15mm).
4. You should drain the water before using the heater and cooler. Clean the inner surface of the pipes chemically every two years
5. The panel frame and all metal parts should be de-rusted and painted once a year.
