Installation Diagram: Shows placement of indoor and outdoor units with minimum space requirements.

Installation of the Indoor Unit:

1. Decide on indoor and outdoor unit positions, considering minimum space.
2. Do not install in wet rooms (bathroom, laundry).
3. Installation site should be at least 250cm above the floor.
4. Mounting Plate Installation: Mount the rear panel horizontally and vertically. Drill 32mm holes, insert anchors, fix the panel with screws. Ensure it can withstand the weight.
5. Drilling a Hole for Piping: Make a 65mm hole with a slight downward slant towards the outdoor side. Insert a piping-hole sleeve. Keep the drain pipe sloped downwards.
6. Electrical Connections (Indoor Unit): Open front panel, remove cover. Connect wires to screw terminals following numbers. Use appropriate wire size and follow safety codes. Ensure the plug is accessible. Use an efficient ground connection. If the power cable is damaged, contact a Service Center.

Refrigerant Piping Connection:

• Piping can be run in 3 directions. Cut notch if needed.
• Bind copper pipes, drain pipe, and power cables together with tape, drain pipe at the bottom.
• Do not remove pipe caps until connecting.
• Avoid bending or pulling pipes excessively. Do not bend more than three times at one point.
• Straighten rolled pipes by gently unwinding.
• Connections to the indoor unit: Remove pipe cap, insert flare nut, create flange, tighten with two wrenches. For R32/R290, use outdoor mechanical connectors.

Indoor Unit Condensed Water Drainage:

• Place drain hose below piping, ensuring no siphons.
• Drain hose must slant downwards.
• Do not bend, kink, or submerge the drain hose in water. Lag extensions.
• Secure pipes, cables, and drain hose with insulating material.

Installation of the Indoor Unit (Alternative): If piping is embedded or connecting on the wall: Remove bottom plate, hook top of indoor unit, unfold bracket, prop up unit, connect piping/wiring/drainage, replace bracket, secure unit, replace bottom plate.

Installation of the Outdoor Unit:

• Install on a solid wall, fastened securely.
• Decide on position for easy maintenance.
• Fasten support with appropriate screw anchors. Use more anchors than required to prevent vibration.
• Install according to national regulations.

Outdoor Unit Condensed Water Drainage (Heat Pump Models): Fasten drain port in the 25mm hole, connect drain port and pipe. Ensure water drains to a suitable place.

Electrical Connections (Outdoor Unit): Remove handle, connect power cord to terminal board, fix cord with clamp, confirm wire fixing, ensure ground connection, recover handle.

Connecting the Pipes: Screw flare nuts to outdoor unit coupling. Tighten using two wrenches. Ensure correct tightening torque to avoid leakage. Use a fix wrench and torque wrench.

Pipe length and Additional refrigerant:

Dedicated Distribution Device and Wire for Air Conditioner:

• Outdoor Power Cable: H07RN-F

• Signal Cable: H07RN-F

Note: Installation must meet local laws and regulations.

Wiring Diagram: Diagrams are pasted on the indoor unit (under front panel) and outdoor unit (backside of outdoor handle cover). Example wiring shown.

Cable Wires Specification: Table provides wire specifications for different inverter models and capacities.

Air Vacuumizing:

• Use a spanner to remove protective caps from service port, low pressure valve, and high pressure valve.
• Connect manifold gauge hoses to service port and vacuum pump.
• Open low pressure valve, close high pressure valve.
• Operate vacuum pump for 10-15 minutes until vacuum reaches -0.1 MPa (-76 cmHg).
• Close low pressure valve, turn off vacuum pump.
• Hold pressure for 5 minutes; check for rebound.
• Turn low pressure valve counterclockwise to fill refrigerant, then close.
• Check all joints for leakage with soapy water or leak detector.
• Fully open low and high pressure valves.
• Replace protective caps and valve cover.

Bleeding: To remove air and humidity from the refrigerant circulation using a vacuum pump.

• Unscrew and remove caps from 2-way and 3-way valves and service port.
• Connect vacuum pump hose to service port.
• Operate vacuum pump for 10-15 minutes until absolute vacuum of 10 mm Hg is reached.
• With pump running, close low-pressure knob. Stop pump.
• Open 2-way valve by 1/4 turn, close after 10 seconds. Check for leaks.
• Turn 2-way and 3-way valves. Disconnect hose.
• Replace and tighten all caps.

Operation Test:

• Indoor Unit Test: Check ON/OFF, FAN, MODE, set point, TIMER, and lamps. Check flap operation and condensed water drainage.
• Outdoor Unit Test: Check for abnormal noise or vibration. Check if noise, airflow, or drainage disturbs neighbors. Check for coolant leakage.

Note: The electronic controller allows the compressor to start only three minutes after voltage has reached the system.

Maintenance

• Shut down machine and cut off power supply for more than 5 minutes before cleaning.
• Do not flush the air conditioner with water.
• Use a soft dry cloth or wet cloth with neutral detergent. Avoid volatile liquids.
• Clean the filter screen regularly to avoid dust accumulation. Increase frequency in dusty environments.
• Do not touch fins of the indoor unit after removing the filter screen.

Clean the Unit: Wipe with a gentle, damp cloth and dry. Tip: Wipe frequently for appearance.

Disassembly and Assembly of Filter Screen: Grasp the plastic handle, pull the filter screen out. Insert the lower end first, then squeeze the upper end into place.

Clean the Filter Screen: Clean with soapy water and air dry. Tip: Clean regularly for efficiency.

Cleaning of Inner Air Duct: Loosen louver knob, bend outwards. Loosen bottom plate, push downwards. Loosen deflector assembly buckle. Wipe air duct and fan assembly with a clean, wrung wet rag. Clean removed parts with soapy water and air dry. Restore parts.

Service and Maintenance (Long-term storage):

• Take out remote controller batteries and disconnect power supply.
• When starting after long-term shutdown: Clean unit and filter screen. Check for obstacles at air inlets/outlets. Check drain pipe. Install remote controller batteries and check power.

Troubleshooting

Malfunctions and Possible Causes:

• Fine mist from air outlet: Occurs in COOLING or DEHUMIDIFYING/DRY modes when room air is very cold.
• Strange noise: Expansion/contraction of front panel due to temperature variations.
• Insufficient airflow, either hot or cold: Unsuitable temperature setting, obstructed intakes/outlets, dirty air filter, fan speed at minimum, heat sources in room, no refrigerant.
• Appliance does not respond to commands: Remote control not close enough, dead batteries, obstacles between remote and receiver, active LIGHT function.
• Display is off: Power failure, uncommon noises, faulty control board/fuses/switches, spraying water, overheated cables/plugs, strong smells.
• Switch off immediately and cut off power supply in the event of: Power failure, uncommon noises, faulty control board, faulty fuses/switches, spraying water/objects, overheated cables/plugs, strong smells.
