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 the following table:

The Maximum Length And Drop Height Based on Models. (Unit: m/ft.)

Type of model| Capacity (Btu/h)| Length of piping| Maximum drop height
---|---|---|---
North America, Australia and the eu frequency conversion Split Type| <15K| 25/82| 10/32.8
³15K – <24K| 30/98.4| 20/65.6
³24K – <36K| 50/164| 25/82
³36K – £60K| 65/213| 30/98.4

CAUTION

Oil traps
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 6m(20ft) of vertical suction line riser (＜36000Btu/h unit). An oil trap should be installed every 10m(32.8ft) of vertical suction line riser (≥36000Btu/h unit).

Connection Instructions – Refrigerant Piping

CAUTION
Insulate both the gas and liquid piping to prevent water leakage.

Step 1: 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.

Measure the distance between the indoor and outdoor units.
Using a pipe cutter, cut the pipe a little longer than the measured distance.
Make sure that the pipe is cut at a perfect 90°angle. ****

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.

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

Hold the pipe at a downward angle to prevent burrs from falling into the pipe.
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.

After removing burrs from cut pipe, seal the ends with PVC tape to prevent foreign materials from entering the pipe.
Sheath the pipe with insulating material.
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.
Remove PVC tape from ends of pipe when ready to perform flaring work.
Clamp flare form on the end of the pipe. The end of the pipe must extend beyond the flare form.
Place flaring tool onto the form.
Turn the handle of the flaring tool clockwise until the pipe is fully flared. Flare the pipe in accordance with the dimensions.

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.

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

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

CAUTION

Ensure 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.

Install the unit by following local switches and regulations , there may be differ slightly between different regions.
