CAUTION

- Do not install the unit at altitude over 2000m for both indoor and outdoor.

REFRIGERANT PIPING

If the pipe is too long, both the capacity and reliability of the unit will drop. As the number of bends increases, resistance to the flow of refrigerant system increases, thus lowering cooling capacity. As a result, the compressor may become defective. Always choose the shortest path and follow the recommendations as tabulated below:

Notes:
1. Equivalent piping length is obtained with actual length of gas piping.
2. 90° bend of piping is equivalent to L joint.
Bending must be carefully made so as not to crush the pipe. Use a pipe bender to bend a pipe where possible.

Piping Works And Flaring Technique

• Do not use contaminated or damaged copper tubing. If any piping, evaporator or condenser had been exposed or had been opened for 15 seconds or more, the system must be vacuumed. Generally do not remove plastic, rubber plugs and brass nuts from the valves, fittings, tubing and coils until it is ready to connect suction or liquid line into valves or fittings.
• If any brazing work is required, ensure that nitrogen gas is passed through coil and joints while the brazing work is being done. This will eliminate soot formation on the inside wall of copper tubings.
• Cut the pipe stages by stages, advancing the blade of pipe cutter slowly. Extra force and a deep cut will cause more distortion of pipe and therefore extra burr. See Figure I.
• Remove burrs from cut edges of the pipes with remover. See Figure II. Hold the pipe on top position and burr remover at lower position to prevent metal chips from entering the pipe. This will avoid unevenness on the flare faces which will cause gas leak.
• Insert the flare nuts, mounted on the connection parts of both the indoor unit and outdoor unit, into the copper pipes.
• The exact length of pipe protruding from the top surface of the swaging block is determined by the flaring tool. See Figure III.
• Fix the pipe firmly on the swaging block. Match the centers of both the swaging block and the flaring punch, then tighten the flaring punch fully.

Piping Connection To The Units

• Align the center of the piping and tighten the flare nut sufficiently with fingers. See Figure IV.
• Finally, tighten the flare nut with torque wrench until the wrench clicks.
• When tightening the flare nut with the torque wrench, ensure that the tightening direction follows the arrow indicated on the wrench.
• The refrigerant pipe connection are insulated by closed cell polyurethane.

• Used the correct screwdriver for terminal screws tightening. Unsuitable screwdrivers can damage the screw head.
• Over tightening can damage the terminal screws.
- Do not connect wire of different gauge to same terminal.
- Keep wiring in an orderly manner. Prevent the wiring from obstructing other parts and the terminal box cover.

Connect wires of the same gauge to both side.

Do not connect wires of the same gauge to one side.

Do not connect wires of different gauges.

SPECIAL PRECAUTIONS WHEN DEALING WITH R410A UNIT

R410A is a new HFC refrigerant which does not damage the ozone layer. The working pressure of this new refrigerant is 1.6 times higher than conventional refrigerant (R22), thus proper installation/servicing is essential.

• Never use refrigerant other than R410A in an air conditioner which is designed to operate with R410A.
• POE or PVE oil is used as lubricant for R410A compressor, which is different from the mineral oil used for R22 compressor. During installation or servicing, extra precaution must be taken not to expose the R410A system too long to moist air. Residual POE or PVE oil in the piping and components can absorb moisture from the air.

- To prevent mischarging, the diameter of the service port on the fl are valve is different from that of R22.

• Use tools and materials exclusively for refrigerant R410A. Tools exclusively for R410A are manifold valve, charging hose, pressure gauge, gas leak detector, fl are tools, torque wrench, vacuum pump and refrigerant cylinder.
• As an R410A air conditioner incurs higher pressure than R22 units, it is essential to choose the copper pipes correctly.
• If the refrigerant gas leakage occurs during installation/servicing, be sure to ventilate fully. If the refrigerant gas comes into contact with fire, a poisonous gas may occur.
• When installing or removing an air conditioner, do not allow air or moisture to remain in the refrigerant cycle.

VACUUMING AND CHARGING

Vacuuming is necessary to eliminate all moisture and air from the system.

Vacuuming The Piping And The Indoor Unit

Except for the outdoor unit which is pre-charged with refrigerant, the indoor unit and the refrigerant connection pipes must be air-purged because the air containing moisture that remains in the refrigerant cycle may cause malfunction of the compressor.

• Remove the caps from the valve and the service port.
• Connect the center of the charging gauge to the vacuum pump.
• Connect the charging gauge to the service port of the 3-way valve.
• Start the vacuum pump. Evacuate for approximately 30 minutes. The evacuation time varies with different vacuum pump capacity. Confirm that the charging gauge needle has moved towards -760mmHg.

Caution

• If the gauge needle does not move to -760mmHg, be sure to check for leakage at fl are type connection of the indoor and outdoor unit and repair the leak before proceeding to the next step.
• Close the valve of the changing gauge and stop the vacuum pump.
• On the outdoor unit, open the suction valve (3 way) and liquid valve (2 way) (in anti-clockwise direction) with 4mm key for hexagon sacked screw.

Charge Operation

This operation must be done by using a gas cylinder and a precise weighing machine. The additional charge is topped-up into the outdoor unit using the suction valve via the service port.

• Remove the service port cap.
• Connect the low pressure side of the charging gauge to the suction service port center of the cylinder tank and close the high pressure side of the gauge. Purge the air from the service hose.

- Start the air conditioner unit.

- Open the gas cylinder and low pressure charging valve.

- When the required refrigerant quantity is pumped into the unit, close the low pressure side and the gas cylinder valve.

- Disconnect the service hose from service port. Put back the service port cap.

Air Flow Control

• For more effective air circulation, you can manually adjust the air discharge grille to the left or right.
• During cool mode operation and dry mode operation, do not direct the air discharge louver downwards for too long. If operating continues in this way, condensation may occur on the louver, thus resulting in drippings.

Overheating Protection (for heat pump unit only)

- In case the internal and/or the external temperature is too high, or that the filter is dirty and clogged up, the refrigerant may be overheated. The compressor will cut out when the condensing temperature reaches 62^ C/143.6°F.

Frost Prevention

• When the air filter is dirty, the evaporating temperature will decrease and eventually cause frosting.
• If the evaporating temperature reaches -1^ / 33.8^ , the unit will trip.

Fan Speed And Rated Cooling Capacity

• The rated cooling capacity is provided at the HIGH fan speed.
• The cooling capacity is lower when the unit is operating at MEDIUM and LOW fan speed.

Notes On Flaps And Louvers Angles

- When "SWING button" is selected, the flaps swinging range depends on the operation mode. (See the figure.)

ATTENTION

• Always use a remote controller to adjust the flaps angle. If you attempt to move it forcibly with hand when it is swinging, the mechanism may be broken.
• Be careful when adjusting the louvers. Inside the air outlet, a fan is rotating at a high speed.

NOTE : When the option is selected, the power supply of the unit need to be reset in order to activate the function.
