Precautions for refrigerant piping
Do not twist or crush piping.Be sure that no dust is mixed in piping.Bend piping with as wide angle as possible.Keep insulating both gas and liquid piping.Check flare-connected area for gas leakage.
Connecting method (indoor unit)Apply refrigerant oil at half union as large and flare nut.To bend a pipe, give the roundness as possible not to crush the pipe.When connecting pipe, hold the pipe centre to centre then screw nut on by hand, refer to Fig.Be careful not to let foreign matters, such as sands enter the pipe.
(4) Piping connection
Forced fastening without centering may damage the threads and cause a gas leakage.
In the first to third test steps, if the pressure drops, check the leakage in each jointuse sense of hearing, feeling and soap water, etc. methods to find the leaking point.After confirming the leaking point, welding it again or tighten the nut tightly again.
From pressurizing to 24 hours later, each 1* difference of ambient temperaturewill make 0.01MPa(0.1kg/cm2g) pressure change. It shall be corrected during test.
Checking the leaking point
Check if the pressure dropsThe pressure does not drop-passedThe pressure drops-check the leaking point.
First step: 0.3MPa (3.0kg/cm2g) pressurize over 3 minutes.
Second step: 1.5Mpa (15kg/cm2g) pressurize over 3 minutes. Large leakage will be found.
Third step: 3.0 MPa (30kg/cm2g) pressurize about 24 hours. Little leakage will be found.
5. Air discharging methodAfter finishing connection of refrigerant pipe, it shall perform air tightness test.The air tightness test adopts nitrogen tank to give pressure according to the pipe connectionmode as the following figure shown.The gas and liquid valve are all in close state. In order to prevent the nitrogen entering thecirculation system of outdoor unit, tighten the valve rod before giving pressure (both gasand liquid valve rods).

It shall use the vacuum pump of (lower than -755mmHg)high vacuum degree and large air discharging (over 40l/min).The vacuumizing time depends on the length of the connecting pipe, generally is 1~2 hours.When vacuumizing, it shall be confirmed both gas and liquid side valves are closed.If after 2 hours vacuumizing, it cannot reach the vacuum degree below -755mmHg, it can bevacuumized for other 1 hour.If after 3 hours vacuumizing, it still cannot reach the vacuum degree below -755mmHg, check if there is any leaking point and repair the them.If after over 2 hours vacuumizing, the vacuum degree is below -755mmHg, close the VLand VH on the meter separator and stop vacuumizing. 1 hour later to confirm if the vacuumdegree changes. If changes, it indicates there is leaking point in the system. Check the leaking point and repair.After finishing the above vacuumizing, change the vacuum pump into refrigerant pump tocharge the refrigerant.
Use vacuum pump to perform vacuumizing. It is strictly forbidden to use the refrigerant to remove the air inside the system.After air tightness test and discharging all the nitrogen, connect the vacuum pumpas the following figure shown.
When the total length (L) of the two indoor units' connecting pipe is less than 5m, it is unnecessary to charge additional refrigerant.If the connecting pipe (L) exceeds 5m, it shall charge Mg additional refrigerant per meter.That is: Refrigerant charging amount = (L-5) x M (g)
For AU242AHBEA, M=65
Only in COOLING operation can charge the additional refrigerant.When charging, the refrigerant shall be charged from the charging nozzle of low pressure vavle.Be carefull when charging refrigerant, do not let the air mix into the system,and must charge the additional refrigerant in liquid condition.

Note · Do grounding work. Do not connect the grounding wire to gas pipe, tap, lighting rod or telephone line. Improper grounding will cause electric shock. ·In some places the electric leakage breaker shall be installed. If do not install the breaker, electric shock may occur. ·After installation, power on to do electric leakage detecting test.
5.3 Special Work and Main Points in Installation Warning
· During installation, if refrigerant leakage occurs, take ventilation measurement immediately. ·As soon as the leaked refrigerant gas meets fire, poisonous gas will generate.
·After finishing installation, confirm the refrigerant gas dose not leak. ·If the refrigerant gas leaks in the room, once it meets heater, burner and gas stove etc. fire source, the poisonous gas will generate.
A. Choosing of pipes According to the following indoor unit and unit installation diagram to choose the material and size of pipes and branch pipes.
B. Connection of pipes 1. Method of pipe connection ·The pipe shall be as short as possible to guarantee efficiency ·Daub the refrigerant oil on the connection and flare nut · When bending the pipes, give the roundness as large as possible, to avoid crashing the pipes ·To connect the pipe, fit the center and screw the nut with hand, the use spanner or torque wrench to tighten it. The fastening torque showed in below table, and shown in figure. ·Be careful alien matter, such as sands, water etc. shall not enter the pipes. Forced fastening without careful centering may damage the threads and cause gas leakage 2. Welding of pipes
·In welding, the nitrogen shall be used to avoid oxidation of the pipe inner part. ·The refrigerating pipe shall use clean new pipes. When working, it shall take steps to prevent
water and dust from entering. ·When loosening and tightening the nuts, two spanners shall be used. If using one spanner, it can
not reach the desired degree of tightness. Using the specified fastening torque to fasten nuts.
After the installation, please to check the connection of wire: If the wire have the same diameter in the two sides of the terminal If the wire placed on both the side of terminal but one side

Pour water into a convex joint.
When constructing drain piping for several units, positionthe common pipe about 100 mm below the drain outletof each unit as shown in the sketch. Use VP-30(11/4")or thicker pipe for this purpose.Be sure to provide heat insulation to hard PVC pipes ofindoor placement.Do not ever provide an air vent.The height of the drain head can be elevated up to apoint 500 mm above the ceiling, and when an obstacleexists in the ceiling space, elevate the piping to avoidthe obstacle using an elbow or corresponding gadget.When doing this, if the stretch for the needed height ishigher than 500 mm, the back-flow quantity of drain atthe event of interruption of the operation gets too muchand it may cause overflow at the drain pan. Therefore,make the height of the drain pipe within the distancegiven in the sketch below.Avoid positioning the drain piping outlet at a place wheregeneration of odor may be stimulated. Do not lead thedrain piping direct into a sewer from where sulfur gas
Drainage Test
Conduct a drainage test after completion of the electrical work.During the trial, make sure that drain flows properly through the piping and that no waterleaks from connections.In case of a new building, conduct the test before it is furnished with the ceiling.Be sure to conduct this test even when the unit is installed in the heating season.
Procedures
Supply about 1000 cc of water to the unit through the air outlet using a feed waterpump.

1. Before installation [Before finishing installation, do not throw the attached parts installation needs]
Confirm the way to move the unit to the installation place.Before moving the unit to the installation place, do not remove their packages.When have to remove the package, use a soft material or protection board with rope to lift the unit assembly to avoid unit damage or bumping a scrape.
2. Choose installation place(1) The chosen installation place should meet the following requirements and get the userís consent.
Place ensures ideal airflow distribution.The passage of airflow has no obstacles.When importing outside air, it should be imported directly from outdoors. (if the pipe can not be extended, it also can not be imported from top)Place ensures enough space for maintenance.The pipe length between indoor and outdoor unit is in the permitted limit (referring to outdoor unit installation part).The indoor unit, outdoor unit, electric wire and connection wire is at least 1m away from television and radio. This is to avoid the image disturbance and noise caused by the above-mentioned home appliance. (Even if 1m away, if the electromagnetic wave is too strong, it can also cause noise.)
(2) The height of ceilingThe indoor unit can install on the ceiling, which height is no more than 3m.
(3) Install and use the hoisting screw. Check if the installation place can bear the weight of unit assembly.
If not certain, strengthen it before install the unit.

Do not insert the drain hose directly into drainage, where the gas with sulfur may be generated.Backwater bendBecause the drain spout is at the position, which negative pressure may occur. So with the rise of water level in the drain pan, water leakage may occur. In order to prevent water leakage, we designed a backwater bend.The structure of backwater bend should be able to be cleaned. As the below figure shown, use T type joint. The backwater bend is set near the air conditioner.
As figure shown, set a backwater bend in the middle of drain hose.

8. The attentive matters in installation of air suction and discharging duct
Recommend to use anti-frost and sound-absorbing duct. (locally bought)The duct installation work should be finished before the fitment of ceiling.The duct must be heat insulated.
The specific air-discharging outlet should be installed at the place where the airflow can be reasonably distributed.The surface should leave a checking meatus for checking and maintenance.
9. The examples of improper installation
Do not use air in duct and take the ceiling inner side instead. The result is because of the irregular outer air mass, strong wind and sunshine, the humidity is increased.There may be water drop on the outside of duct. For cement and other new constructions, even if not taking ceiling inner side as duct, the humidity will also be so high. At this time, use glass fiber to perform heat preservation to the whole. (use iron net to bind the glass fiber)
Affected by the capacity of air discharging fan, the strong wind in the outer duct and wind direction, when unit air sending volume exceeds the limit, the discharged water of heat exchanger will overflow, leading to water leakage.
