- Caution 11
- Do not install the unit in the following locations 11
- In areas that store flammable materials or gas 11
- In areas with oil drilling or fracking 11
- In areas with power fluctuations such as factories in enclosed spaces such as cabinets 11
- In areas with strong electromagnetic waves 11
- In coastal areas with high salt content in the air in areas with caustic gases in the air such as near hot springs 11
- In kitchens that use natural gas 11
- In rooms with high humidity such as bathrooms or laundry rooms 11
- Note panel installation should be done after piping and wiring 11
- Caution 12
- The unit body should align perfectly with the hole ensure that the unit and the hole are the same size before moving on 12
- Caution 13
- Be sure to remove any obstacles that may block air circulation 14

- Cm 9 or more 16
- Note make sure the water drains to a safe location where it will not cause water damage or a slipping hazard 16
- Note the minimum distance between the outdoor unit and walls described in the installation guide does not apply to airtight rooms be sure to keep the unit unobstructed in at least two of the three directions m n p see fig 4 0 16
- Note when drilling the wall hole make sure to avoid wires plumbing and other sensitive components 16
- Caution 17
- Drainpipe installation 17
- All feld piping must be completed by a licensed technician and must comply with the local and national regulations 19
- An oil trap should be installed every 10m 32 ft of vertical suction line riser see fig 6 19
- Caution 19
- If the indoor unit is installed higher than the outdoor unit 19
- Oil traps 19
- Refrigerant piping connection 19
- Ventilate the area immediately if there is refrigerant leakage during the installation leaked refrigerant gas is both toxic and flammable ensure there is no refrigerant leakage after completing the installation work 19
- When installing the refrigeration system ensure that air dust moisture or foreign substances do not enter the refrigerant circuit contamination in the system may cause poor operating capacity high pressure in the refrigeration cycle explosion or injury 19
- When the air conditioner is installed in a small room measures must be taken to prevent the refrigerant concentration in the room from exceeding the safety limit in the event of refrigerant leakage if the refrigerant leaks and its concentration exceeds its proper limit hazards due to lack of oxygen may result 19
- Caution 20
- Note use both a spanner and a torque wrench when connecting or disconnecting pipes to from the unit 21
- Carefully bend the tubing in the middle according to the diagram below do not bend the tubing more than 90 or more than 3 times 22
- Caution 22
- Check to make sure there is no refrigerant leak after completing the installation work if there is a refrigerant leak ventilate the area immediately and evacuate the system refer to the air evacuation section of this manual 22
- Ensure to wrap insulation around the piping direct contact with the bare piping may result in burns or frostbite 22
- Make sure the pipe is properly connected over tightening may damage the bell mouth and under tightening may lead to leakage 22
- Note do not intertwine signal cable with other wires while bundling these items together do not intertwine or cross the signal cable with any other wiring 22
- Caution 23
- Warning 23
- Wiring 23
- Before performing any electrical or wiring work turn of the main power to the system 24
- Note while connecting the wires please strictly follow the wiring diagram found inside the electrical box cover 24
- Warning 24
- Caution 25
- The refrigerant circuit can become very hot keep the interconnection cable away from the copper tube 25
- While connecting the wires please strictly follow the wiring diagram 25
- Air evacuation 26
- Caution 26
- Appropriate refrigerant is used refrigerant containers must be opened slowly always use protective gear when charging the system 27
- Caution 27
- Charging with unsuitable substances may cause explosions or accidents ensure that the 27
- Do not mix refrigerants types 27
- For the r290 or r32 refrigerant model make sure the condtions within the area have been made safe by control of fammable material when the refrigerant added into air conditioner 27
- Liquid side diameter 27
- Note on adding refrigerant 27
- Refrigerant charging must be performed after wiring vacuuming and the leak test do not exceed the maximum allowable quantity of refrigerant or overcharge the system doing so can damage or impact the unit s function 27
- Some systems require additional charging depending on pipe lengths the standard pipe length varies according to local regulations for example in north america the standard pipe length is 7 m 25 in other areas the standard pipe length is 5m 16 the additional refrigerant to be charged can be calculated using the following formula 27
- Caution 28
- Do not place the panel facedown on the floor against a wall or on uneven surfaces 28
- Panel installation 28
- Caution 30
- Failure to perform the test run may result in unit damage property damage or personal injury 30
- If the unit malfunctions or does not operate according to your expectations please refer to the troubleshooting section of the owner s manual before calling customer service 30
- Test run 30
- European disposal guidelines 31
- Note disposing of this appliance in the forest or other natural surroundings endangers your health and is bad for the environment hazardous substances may leak into the ground water and enter the food chain 31
- Information servicing 32
- Required for the units adopt r32 r290 refrigerant only 32
- The area shall be checked with an appropriate refrigerant detector prior to and during work to ensure the technician is aware of potentially flammable atmospheres ensure that the leak detection equipment being used is suitable for use with flammable refrigerants i e no sparking adequately sealed or intrinsically safe 32
- Works shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being present while the work is being performed 32
