Be sure to keep the unit unobstructed connect the indoor and outdoor units. in at least two of the three directions (M, N, P) 1. Determine the location of the wall hole (See Fig. 6.8) based on the location of the outdoor unit.
7 Refrigerant Piping Connection Safety Precautions WARNING • All field piping must be completed by a When preparing refrigerant pipes, take extra care to cut and flare them properly. This will ensure efficient operation and minimize the need for future maintenance. For R32/R290 refrigerantmodels, the pipe connection points must be placed outside of room. The connection pipes can not be reused. 1. Measure the distance between the indoor and outdoor units. 2.

Fig. 7.2 Refrigerant Piping Connection Step 3: Flare pipe ends Proper flaring is essential to achieve an airtight seal. 1. After removing burrs from cut pipe, seal the ends with PVC tape to prevent foreign materials from entering the pipe. 2. Sheath the pipe with insulating material. 3. Place flare nuts on both ends of pipe.
NOTE: Use both a spanner and a torque wrench when connecting or disconnecting pipes to/from the unit. 7. Thread this pipeline through the wall and connect it to the outdoor unit. 8. Insulate all the piping, including the valves of the outdoor unit. 9. Open the stop valves of the outdoor unit to start the flow of the refrigerant between the indoor and outdoor unit. CAUTION Check to make sure there is no refrigerant leak after completing the installation work.
8 Wiring Safety Precautions WARNING • • • • • • Wiring • • Be sure to disconnect the power supply before working on the unit. All electrical wiring must be done according to local and national regulations. Electrical wiring must be done by a qualified technician. Improper connections may cause electrical malfunction, injury and fire. An independent circuit and single outlet must be used for this unit. DO NOT plug another appliance or charger into the same outlet.

9 Air Evacuation Safety Precautions CAUTION • Use a vacuum pump with a gauge reading lower than -0.1MPa and an air discharge capacity above 40L/min. • The outdoor unit does not need vacuuming. DO NOT open the outdoor unit’s gas and liquid stop valves. • Ensure that the Compound Meter reads -0.1MPa or below after 2 hours. If after three hours of operation and the gauge reading is still above -0.1MPa, check if there is a gas leak or water inside the pipe.
Note On Adding Refrigerant CAUTION • Refrigerant charging must be performed after wiring, vacuuming, and the leak testing. • DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system. Doing so can damage the unit or impact it’s functioning. • Charging with unsuitable substances may cause explosions or accidents. Ensure that the appropriate refrigerant is used. • Refrigerant containers must be opened slowly. Always use protective gear when charging the system.
Safety And Leakage Check Electrical safety check Perform the electrical safety check after completing installation. Cover the following areas: 1. Insulated resistance The insulated resistance must be more than 2M . 2. Grounding work After finishing grounding work, measure the grounding resistance by visual detection and using the grounding resistance tester. Make sure the grounding resistance is less than 4 . 3.
Test Run Before Test Run A test run must be performed after the entire system has been completely installed. Confirm the following points before performing the test: a) The indoor and outdoor units are properly installed. b) Piping and wiring are properly connected. c) No obstacles near the inlet and outlet of the unit that might cause poor performance or product malfunction. d) The refrigeration system does not leak. e) Drainage system is unimpeded and draining to a safe location.
Function of Automatic Wiring/Piping Correction 11 Automatic Wiring/Piping Correction Function More recent models now feature automatic correction of wiring/piping errors. Press the "check switch" on the outdoor unit PCB board for 5 seconds until the LED displays "CE”, indicatomg that this function is working, Approximately 5-10 minutes after the switch is pressed, the "CE" disappears, meaning that the wiring/piping error is corrected and all wiring/piping is properly connected.
European Disposal Guidelines 12 Users in European Countries may be required to properly dispose of this unit. This appliance contains refrigerant and other potentially hazardous materials. When disposing of this appliance, the law requires special collection and treatment. DO NOT dispose of this product as household waste or unsorted municipal waste. When disposing of this appliance, you have the following options: • Dispose of the appliance at designated municipal electronic waste collection facility.
Information Servicing (Required for the units adopt R32/R290 Refrigerant only) 13 1. Checks to the area Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimised. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system. 2.
the charge size is in accordance with the room size within which the refrigerant containing parts are installed; the ventilation machinery and outlets are operating adequately and are not obstructed; if an indirect refrigerating circuit is being used, the secondary circuits shall be checked for the presence of refrigerant; marking to the equipment continues to be visible and legible.
11. Repair to intrinsically safe components Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use. Intrinscially safe components are the only types that can be worked on while live in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating. Replace components only with parts specified by the manufacturer.
When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipe-work are to take place. Ensure that the outlet for the vacuum pump is not closed to any ignition sources and there is ventilation available. 16.
18. Labelling Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant. 19. Recovery When removing refrigerant from a system, either for service or decommissioning, it is recommended good practice that all refrigerants are removed safely.
