Page 10: About The Refrigerant
About The Refrigerant WARNING The following applies to R32 refrigerant systems. Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimized. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system. - Page 11 During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
- Page 12 i) Do not exceed the maximum working pressure of the cylinder, even temporarily. j) When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off. k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.

Installation Carefully read this manual before installing the indoor unit.. Installation Precautions WARNING Make sure to carry out the installation according to local legislation. Ask your local dealer or professionals to install the product. This unit must be installed by pqualified persons. Users MAY NOT install the unit themselves; otherwise, faulty operations may cause the risks of fire, electrical shock, injury, or leakage, which could harm you or others or damage the air conditioner. - Page 20 short circuit. Do not store the unit in a humid basement or expose it to rain or water. Make sure the installation base and lifting are robust and reliable; Insecure installation of the base may cause the air conditioner to fall, leading to an accident. Take into full consideration the effects of strong winds, typhoons and earthquakes, and reinforce the installation.
- Page 21 Precautions For Transporting And Lifting The Air Conditioner Before transporting the air conditioner, determine the path that will be used to move it to the installation site. Do not unpack the air conditioner until it is transported to the installation site. When unpacking and moving the air conditioner, must hold the Lifting Lugs and do not apply force to other parts, especially the refrigerant piping, drain pipe and plastic accessories, so as to avoid damaging the air conditioner and causing personal injury.
- Page 22 Recommended Installation Sites It is recommended to install the air conditioner according to the design drawing of the HVAC engineer. The selection principle for the installation site is as follows: Ensure that the airflow in and out of the indoor unit is reasonably organized to form an air circulation in the room. Prevent the air conditioner from blowing directly at the human body.

Page 64: Safety Warning
Maintenance and Service Safety Warning WARNING For safety reasons, always turn off the air conditioner and turn off the power before cleaning the air conditioner. Do not disassemble or repair the air conditioner by yourself; otherwise, it may cause fire or other hazards. Only professional service personnel can carry out the maintenance. - Page 65 Cleaning The Air Filter CAUTION Air filters can be used to remove dust or other particles from the air, and if clogged, the effectiveness of the air conditioner will be greatly reduced. Therefore, be sure to clean the air filter frequently when using it for an extended period.If it is installed in a place with a lot of dust, it is recommended that you clean the filter once a month.
- Page 66 CAUTION To avoid deformation of the filter, do not use fire or a burning appliance to dry the filter. If the filter is dirty, use a soft brush and neutral detergent to clean it, then shake off the water and dry it in a cool place.
