Outdoor Unit Installation

Install the unit by following local codes and regulations, which may differ slightly from region to region. Installation Instructions – Outdoor unit
Step 1: Select installation location
Before installing the outdoor unit, you must choose an appropriate location. The following are standards that will help you choose an appropriate location for the unit.
Proper installation locations meet the following standards:

• Meets all spatial requirements shown in Installation Space Requirements above.
•  Good air circulation and ventilation
• Firm and solid—the location can support the unit and will not vibrate
•  Noise from the unit will not disturb others
• Protected from prolonged periods of direct sunlight or rain
• Where snowfall is anticipated, raise the unit above the base pad to prevent ice buildup and coil damage. Mount the unit high enough to be above the average accumulated area snowfall. The minimum height must be 18 inches

DO NOT install unit in the following locations:

• Near an obstacle that will block air inlets and outlets
• Near a public street, crowded areas, or where noise from the unit will disturb others
• Near animals or plants that will be harmed by hot air discharge
•  Near any source of combustible gas
• In a location that is exposed to large amounts of dust
•  In a location exposed to excessive amounts of salty air

Special Considerations For Extreme Weather
If the unit is exposed to heavy wind:
Install unit so that air outlet fan is at a 90° angle to the direction of the wind. If needed, build a barrier in front of the unit to protect it from extremely heavy winds.
See Figures below. If the unit is frequently exposed to heavy rain or snow:
Build a shelter above the unit to protect it from the rain or snow. Be careful not to obstruct air flow around the unit.
If the unit is frequently exposed to salty air (seaside):
Use outdoor unit that is specially designed to resist corrosion.
Step 2: Install drain joint (Heat pump unit only)
Before bolting the outdoor unit in place, you must install the drain joint at the bottom of the unit. Note that there are two different types of rain joints depending on the type of outdoor unit.
If the drain joint comes with a rubber seal (see Fig. A), do the following:

1. Fit the rubber seal on the end of the drain joint that will connect to the outdoor unit.
2.  Insert the drain joint into the hole in the base pan of the unit.
3. Rotate the drain joint 90° until it clicks in place facing the front of the unit.
4. Connect a drain hose extension (not included) to the drain joint to redirect water from the unit during heating mode.

If the drain joint doesn’t come with a rubber seal (see Fig. B), do the following:

1. Insert the drain joint into the hole in the baseman of the unit. The drain joint will click in place.
2. Connect a drain hose extension (not included) to the drain joint to redirect water from the unit during heating mode.

IN COLD CLIMATES
In cold climates, make sure that the drain hose is as vertical as possible to ensure swift water drainage. If water drains too slowly, it can freeze in the hose and flood the unit.
Step 3: Anchor outdoor unit
The outdoor unit can be anchored to the ground or to a wall-mounted bracket with bolt (M10). Prepare the installation base of the unit according to the dimensions below.
Unit Mounting Dimensions
The following is a list of different outdoor unit sizes and the distance between their mounting feet. Prepare the installation base of the unit according to the dimensions below.

1/2H<L≤H| 11.8 in/30 cm or more
L>H| Can’t be installed

Notes On Drilling Hole In Wall
You must drill a hole in the wall for the refrigerant piping, and the signal cable that will connect the indoor and outdoor units.

1. Determine the location of the wall hole based on the location of the outdoor unit.

2.  Using a 2.5 in (65 mm) core drill, drill a hole in the wall.
   NOTE: When drilling the wall hole, make sure to avoid wires, plumbing, and other sensitive components.

3.  Place the protective wall cuff in the hole. This protects the edges of the hole and helps seal it when you finish the installation process.

Notes On Drilling Hole In Wall
When Selecting a 24k Indoor Unit
The 24k indoor unit can only be connected with an A system. If there are two 24k indoor units, they can be connected with A and B systems. Connective pipe size an A and B systems.

Refrigerant Piping Connection

When connecting refrigerant piping, do not let substances or gasses other than the specified refrigerant enter the unit. The presence of other gasses or substances will lower the unit’s capacity, and can cause abnormally high pressure in the refrigeration cycle. This can cause explosion and injury.
Connection Instructions – Refrigerant Piping
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.

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.

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.
3.  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.

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.  Sheath the pipe with insulating material.
3. 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
4. Remove PVC tape from ends of pipe when ready to perform flaring work.
5. Clamp flare form on the end of the pipe. The  end of the pipe must extend beyond the flare form.
6. Place flaring tool onto the form.
7.  Turn the handle of the flaring tool clockwise until the pipe is fully flared. Flare the pipe in accordance with the dimensions .

8. 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 them 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 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
   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.

6. 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 cablewith any other wiring.

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

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

9. Open the stop valves of the outdoor unit to start the flow of the refrigerant between the indoor and outdoor unit.

CAUTION
After completing the installation work, make sure there is no refrigerant leak. If there is, ventilate the area immediately and evacuate the system (refer to the Air Evacuation section of this manual).

CAUTION
After the confirmation of the above conditions, prepare the wiring as follows:

• Never fail to delegate an individual power circuit specifically for the air conditioner. For the method of wiring, use the circuit diagram posted on the inside of the control cover as a guide.
• The screws which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit will be subjected during the course of transportation. Check to make sure they are all tightly fastened. (If they are loose, the wires could burn out.)
• Specification of power source.
• Confirm that the electrical capacity is sufficient.
• See that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate.
• Confirm that the cable thickness is as specified in the power source specification.
• Always install an earth leakage circuit breaker in a wet or moist area.
• The following could be caused by a voltage drop: The vibration of a magnetic switch (which will damage the contact point), the breakage of a fuse, or the disturbance of the normal function of the overload.
• The means for disconnection from a power supply must be incorporated in the fixed wiring and have an air gap contact separation of at least 0.12 in (3 mm) in each active (phase) conductor
• Before terminals are accessed, all supply circuits must be disconnected.

Air Evacuation

Safety Precautions
CAUTION

• Use a vacuum pump with a gauge reading lower than -0.1 MPa and an air discharge capacity above 40 L/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 -0.1 MPa or below after 2 hours. If after 3 hours of operation the gauge reading is still above -0.1 MPa, check if there is a gas leak or water inside the pipe. If there is no leakage, perform another evacuation for 1 or 2 hours.
• DO NOT use refrigerant gas to evacuate the system.

Evacuation Instructions
Before using the manifold gauge or vacuum pump, read their operation manuals to familiarize yourself with how to use them properly.

1. Connect the charge hose of the manifold gauge to the service port on the outdoor unit’s low-pressure valve.

2.  Connect another charge hose from the manifold gauge to the vacuum pump.

3. Open the low-pressure side of the manifold gauge. Keep the low-pressure side closed.

4.  Turn on the vacuum pump to evacuate the system.

5.  Run the vacuum for at least 15 minutes, or until the compound meter reads -76 cmHG (-1×105 Pa).

6. Close the low-pressure side of the manifold gauge and turn off the vacuum pump.

7. Wait 5 minutes, then check that there has been no change in the system pressure.
   NOTE: If there is no change in the system pressure unscrew the cap from the packed valve (high-pressure valve). If there is a change in the system pressure, there may be a gas leak.

8. Insert a hexagonal wrench into the packed valve (high-pressure valve) and open the valve by turning the wrench counterclockwise a 1/4 turn. Listen for gas to exit the system, then close the valve after 5 seconds.

9. Watch the Pressure Gauge for one minute to make sure that there is no change in pressure. The pressure gauge should read  slightly higher than atmospheric pressure.

10. Remove the charge hose from the service port.

11. Using a hexagonal wrench, fully open both the high-pressure and high-pressure valves.
    OPEN VALVE STEMS GENTLY
    When opening valve stems, turn the hexagonal wrench until it hits against the stopper. DO NOT try to force the valve to open further.

12. Tighten the valve caps by hand, then tighten them using the proper tool.

13.  If the outdoor unit uses all vacuum valves, and the vacuum position is at the main valve, the system is not connected with the indoor unit and must be tightened with a screw nut. Check the gas leakage before operation to prevent leakage.

Note on Adding Refrigerant
CAUTION

• Refrigerant charging must be performed after wiring, vacuuming, and the leak test.
• DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system.
• Doing so may damage or impact the unit’s function.
• 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.
• DO NOT mix refrigerant types

N=2 (one-twin models), N=3 (one-three models), N=4 (one-four models), N=5 (one-five models). Some systems require additional charging depending on pipe lengths. The standard pipe length varies according to local regulations. For example, in North America, the standard pipe length is 25 ft (7.5 m) In other areas, the standard pipe length is 16 ft (5 m). The additional refrigerant to be charged can be calculated using the following formula:
Additional Refrigerant Per Pipe Length

1/4”) (Total pipe length – standard pipe length x N) x 15 g/m. (Total pipe length
– standard pipe length x N) x 0.16 oZ/ft| Liquid Side: Ø 9.52 (Ø 3/8”) (Total pipe length – standard pipe length x N) x 30 g/m. (Total pipe length
standard pipe length x N) x 0.32 oZ/ft

Safety And Leakage Check
Electrical safety check
Perform the electric safety check after completing installation:

1. Insulated resistance The insulated resistance must be more than 2 MΩ.
2. Grounding work After finishing the grounding work, measure the grounding resistance by visual detection and with a grounding resistance tester. Make sure the grounding resistance is less than 4 Ω.
3. Electrical leakage check (performed during test running) During test operation after installation is finished, the service man can use the electroprobe and multimeter to perform the electrical leakage check. Turn off the unit immediately if there is leakage. Look for a solution to the problem until the unit operates properly.

Gas leak check

1. Soapy water method:
   To check for leakage in the connecting points of the piping, use a soft brush to apply soapy water or a liquid neutral detergent to the indoor or outdoor unit connections. If bubbles come 0out, there is leakage.

2. Leak detector Use the leak detector to check for leakage.
