CAUTION

• The drain pipe of the indoor unit must be heat insulated, or it will condense dew, as well as the connections of the indoor unit.
• Hard PVC binder must be used for pipe connection, and make sure there is no leakage.
• With the connection part to the indoor unit, please be noted not to impose pressure on the side of the indoor unit pipes.
• When the declivity of the drain pipe downwards is over 1/100, there should not be any winding.
• The total length of the drain pipe, when pulled out transversely, shall not exceed 65.62ft/20m, when the pipe is overlong, a prop stand must be installed to prevent winding.
• Refer to Fig.7-1 for the installation of the pipes.

Drainage test

• Check whether the drainpipe is unhindered.
• New built house should have this test done before paving the ceiling.

INSTALL THE CONNECTING PIPE

Safety Precautions

WARNING

• All field piping must be completed by a licensed technician and must comply with the local and national regulations.

• 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.

• 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.

• 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.

Notes On Pipe Length and Elevation
Ensure that the length of the refrigerant pipe, the number of bends, and the drop height between the indoor and outdoor units meets the requirements shown in your outdoor IOM.

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. 8.1)

CAUTION
If the outdoor unit is installed higher than the indoor unit: It is recommended that vertical suction risers not be upsized. Proper oil return to the compressor should be maintained with suction gas velocity. If velocities drop below7.62m/s(1500fpm (feet per minute)), oil return will be decreased. An oil trap should be installed every 6m(20ft) of vertical suction line riser. (See Fig. 8.2)

• The indoor unit is installed higher than the outdoor unit
• The outdoor unit is installed higher than the indoor unit

Refrigerant Piping Connection Instructions

CAUTION

• The branching pipe must be installed horizontally. An angle of more than 10° may cause malfunction.
• DO NOT install the connecting pipe until both indoor and outdoor units have been installed.
• Insulate both the gas and liquid piping to prevent water leakage.

Step1: Cut pipes
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.

1. Measure the distance between the indoor and outdoor units.
2. Using a pipe cutter, cut the pipe a little longer than the measured distance.

CAUTION
DO NOT deform pipe while cutting. Be extra careful not to damage, dent, or deform the pipe while cutting. This will drastically reduce the heating efficiency of the unit.

1. Make sure that the pipe is cut at a perfect 90° angle. Refer to Fig. 8.3 for examples of bad cuts

Step 2: Remove burrs.
Burrs can affect the air-tight seal of refrigerant piping connections. They must be completely removed.

1. Hold the pipe at a downward angle to prevent burrs from falling into the pipe.
2. Using a reamer or deburring tool, remove all burrs from the cut section of the pipe.

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. Place flare nuts on both ends of pipe. Make sure they are facing in the right direction, because you can’t put them on or change their direction after flaring. See Fig. 8.5
3. Remove PVC tape from ends of pipe when ready to perform flaring work.
4. Clamp flare form on the end of the pipe. The end of the pipe must extend beyond the flare form.
5. Place flaring tool onto the form.
6. Turn the handle of the flaring tool clockwise until the pipe is fully flared. Flare the pipe in accordance with the dimensions shown in table 8.2.

Table 8.2: PIPING EXTENSION BEYOND FLARE FORM

Remove the flaring tool and flare form, then inspect the end of the pipe for cracks and even flaring.

Step 4: Connect pipes
Connect the copper pipes to the indoor unit first, then connect it to the outdoor unit. You should first connect the low-pressure pipe, then the high- pressure pipe.

1. When connecting the flare nuts, apply a thin coat of refrigeration oil to the flared ends of the pipes.
2. Align the center of the two pipes that you will connect.
3. Tighten the flare nut as tightly as possible by hand.
4. Using a spanner, grip the nut on the unit tubing.
5. While firmly gripping the nut, use a While firmly gripping the nut, use a torque wrench to tighten the flare nut according to the torque values in table 8.2.

NOTE: Use both a spanner and a torque wrench when connecting or disconnecting pipes to/from the unit.

CAUTION

• Be sure to wrap insulation around the piping. Direct contact with the bare piping may result in burns or frostbite.
• Make sure the pipe is properly connected. Over tightening may damage the bell mouth and under-tightening may lead to leakage.

NOTE ON MINIMUM BEND RADIUS

• 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.

• After connecting the copper pipes to the indoor unit, wrap the power cable, signal cable and the piping together with binding tape.
  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.

• Thread this pipeline through the wall and connect it to the outdoor unit.

• Insulate all the piping, including the valves of the outdoor unit.

• 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. If there is a refrigerant leak, ventilate the area immediately and evacuate the system (refer to the Air Evacuation section of this manual).

AIR EVACUATION

Safety Precautions

CAUTION

• The outdoor unit does not need vacuuming. DO NOT open the outdoor unit’s gas and liquid stop valves.
• DO NOT use refrigerant gas to evacuate the system.

Evacuation Instructions
