6.2 Installation for AD362AHERA
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 users 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 ceiling The 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.

(2) If necessary, cut the opening installation and checking needed on the ceiling. (If has ceiling) Before installation, finish the preparation work of all the pipes (refrigerant, drainage) and wire (wire controller connection wire, indoor and outdoor unit connection wire) of indoor unit, so that after installation, they can be immediately connected with outdoor unit. Cut the opening on the ceiling. Maybe it needs to strengthen the ceiling to keep the ceiling even and flat and prevent the ceiling from vibration. For details, please consult to the builder.

Note When the dimensions of main unit and ceiling holes does not match, it can be adjusted with the slot holes of hanging bracket. Adjusting to the levelness (a) Adjust the out-of levelness using a level or by the following method. Make adjustment so that the relation between the lower surface of the unit proper and water level in the hose becomes as given below.
Piping side Supply water Water level 0~5 mm (0~0.2")
PVC hose
Bring the piping side slightly lower.
(b) Unless the adjustment to the levelness is made properly, malfunctioning or failure of the float switch may occur.
5. Drain Piping
(a) Drain piping should always be in a downhill grade (1/50~1/100) and avoid riding across an elevation or making traps.
Improper piping
Good piping Suspension 1.5m ~ 2m bolts
Avoid riding across an elevation Keep free from traps
Air vent
Do not pipe under water A downhill grade Heat insulation of 1/100 or more
(b) When connecting the drain pipe to unit, pay suffcient attention not to apply excess force to the piping on the unit side. Also, fix the piping at a point as close as possible to the unit. Stage (c) For drain pipe, use hard PVC general purpose pipe VP-25(I.D.1") which can be purchased locally. When connecting, insert a PVC pipe end securely into the drain socket before tightening securely using the attached drain hose and clamp. Adhesive must not be used connection of the drain socket and drain hose (accessory).

(f) Avoid putting the outlet of drain hose in the places with irritant gas generated. Do not insert the drain hose directly into drainage, where the gas with sulfur may be generated. (g) Backwater bend Because 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.
H1=100mm or the static pressure of air sending motor H2=1/2H1 (or between 50~100mm)
Drainage Test 1 2 3 4
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 water leaks 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 1 2
Supply about 1000 cc of water to the unit through the air outlet using a feed water pump. Check the drain while cooling operation.

Please consult the after-sales service worker of Haier Air Conditioner for the choosing and installation of suction inlet, suction duct, discharging outlet and discharging duct. Calculating the design drawing and outer static pressure, and choose the discharging duct with proper length and shape. The length difference among every duct is limited below 2:1. Reduce the length of duct as possible as can. Reduce the amount of bend as possible as can. Use heat insulation material to bind and seal the part connecting main unit and the flare part of air discharging duct. Perform duct installation work, before the ceiling fit. Bad example

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.
Special air discharging outlet Use screw bolt to fix Duct Air

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) Maybe exceeding the unit operation limit (for example: when indoor dry bulb temperature is 35degree, web bulb temperature is 24degree), it may lead to overload of compressor. 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. 22

Air discharging fan Improper example 10. The operation method of fan controller Through the fan controller switch in the electric box, the air volume of this unit can be continuously adjusted. It is unnecessary to adjust air volume through the duct side wind level (unit outside static adjustment). The air volume set should be in the operation air volume range. Figure I shows the position of fan controller in the electric box and operation method. After finishing the electric work, perform test run. According to the main points in Figure II making the chosen switch No. accordant. And confirm if it reaches the needed air volume. Note: 1) When operating the fan controller, it is possible to touch the electric charging part, so do cut off the power supply. 2) Do not set the dial at the position less than 1. 3) The figure circled in Figure II indicate the capacity number of fan controller. The non-listed capacity number may exceed the permitted operation capacity range, so it is impossible to operate. 4) When delivering from factory, the capacity number of fan controller is set at No.5.
