Rotate the drain joint 90° until it clicks in place facing the front of the unit. 4.
6 Drainpipe Installation The drainpipe is used to drain water from the unit. Improper installation may cause unit and property damage. 1-1.5m (39-59”) CAUTION Downward slope 1/100 Insulate all piping to prevent condensation and water damage. • If the drainpipe is bent or installed incorrectly, water may leak and cause a malfunction of the water-level switch. • In HEAT mode, the outdoor unit will discharge water.
3. Using a 65-mm (2.5”) core drill, drill a hole in the wall. Make sure that the hole is drilled at a slight downward angle, so that the outdoor end of the hole is lower than the indoor end by about 12mm (0.5”). This will ensure proper water drainage (See Fig. 6.4). Place the protective wall cuff in the hole. This protects the edges of the hole and will help seal it when you finish the installation process. Wall Outdoor Indoor Drainpipe Installation ≈ 12mm / 0.5 inch Fig. 6.

CAUTION • CAUTION Oil traps If the indoor unit is installed higher than the outdoor unit: -If oil flows back into the outdoor unit’s compressor, this might cause liquid compression or deterioration of oil return. Oil traps in the rising gas piping can prevent this. An oil trap should be installed every 10m (32.8ft) of vertical suction line riser. (See Fig. 7.2) If the outdoor unit is installed higher than the indoor unit: -It is recommended that vertical suction risers not be upsized.

8 Wiring Safety Precautions WARNING • • • • • • • CAUTION • • • • Connect the outdoor wires before connecting the indoor wires. Make sure you ground the unit. The grounding wire should be away from gas pipes, water pipes, lightning rods, telephone or other grounding wires. Improper grounding may cause electrical shock. DO NOT connect the unit with the power source until all wiring and piping is completed.

Using wire strippers, strip the rubber jacket from both ends of a signal cable to reveal about 15cm (5.9”) of the wires inside. c. Strip the insulation from the ends of the wires. d. Using a wire crimper, crimp u-lugs on the ends of the wires. NOTE: While connecting the wires, strictly follow the wiring diagram (found inside the electrical box cover). 2.
CAUTION • While connecting the wires, please strictly follow the wiring diagram. • The refrigerant circuit can become very hot. Keep the interconnection cable away from the copper tube. 5. Clamp down the cable with the designated cable clamp to secure it in place. The cable should not be loose and should not pull on the u-lugs. 6. Reattach the electric box cover.

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.
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) 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) Refrigeration system does not leak. e) Drainage system is unimpeded and draining to a safe location.
European Disposal Guidelines 11 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) 12 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.
