Installation of the outdoor unit • Try to ship the product to the installation location in its original package. • During shipping, the outdoor unit must not be slanted to over 45 degrees. (Do not store the unit in a horizontal way.) • As the gravity centre of the unit is not at the installation centre, special caution should be taken when using hoisting cables to lift it up. • Use expansion bolts to fix the mounting supports on the wall. • Use bolts and nuts to fix the outdoor unit firmly on the supports and keep on the same level. • If the unit is to be installed in areas with strong wind, such as in coastal areas or at places high above sea level, or on a rooftop, the outdoor unit should be installed against a wall and the supports firmly fixed to ensure normal fan operation. • If installing parellel units, make sure to maintain the clearances below (Fig.14).
Installation (Cont.) Pipe connection and air purging * * The following pipe connection and air purging instructions are only suitable for air conditioner models other than quick coupler models. Instructions for quick coupler models follow on page 13. The air conditioning system must be installed in way that ensures that no dust, foreign articles, air or moisture can enter the system. Pay particular attention when connecting the pipes for the outdoor unit. • Try to avoid repeated curves as much as possible, otherwise the copper pipes may harden or crack. • Use suitable wrenches for connecting the pipes so as to ensure appropriate torque. Refer to the torque table below for torque values (Table 1). Excessive torque might damage the joints while too little torque might lead to leakage.
Table 1: Torque values, based upon the wrench to be used
Installation (Cont.) Air purging with a vacuum pump After having connected the indoor and outdoor units, make sure all pipes have been properly connected, then bleed the air and humidity from the refrigerant circuit by following the below steps. 1. Remove the charging port cap and connect the manifold gauge and the vacuum pump to the charging valve by service hoses, as illustrated (Fig.15). 2. Open the valve of the low pressure side of the manifold gauge, then run the vacuum pump. Vacuum the indoor unit and the connecting pipes for about 10 minutes until the pressure in them has dropped to below 1.5mmHg. When the desired vacuum has been reached, close the low pressure valve of the manifold gauge and stop the pump. 3. Disconnect the service hoses and fit the cap to the charging valve. 4. Remove the blank caps and fully open the spindles of the 2-way and 3-way valves with a service valve wrench. 5. Tighten the blank caps of the 2-way and 3-ways valves, applying the appropriate torque as listed on page 11 (Table 1).
Adding refrigerant Refrigerant must be added if the piping measures more than 5 metres in length. This operation can only be performed by a professional technician. For the additional amount of refrigerant required, see the Table 2 below.
Installation (Cont.) Gas leakage inspection After the pipeline connection is done, use a leakage inspection device or soap suds to carefully check if there is any leakage at the joints. This is an important step to ensure the quality of installation. Once a leakage is detected, proper treatment should be taken immediately.
Pipe connection for split type quick coupler models If you have purchased the air conditioner for split type quick coupler models, follow the below pipe connection instructions. (This section does not apply to the AK-9000-RC Air Conditioner.) Fig.16 1. Remove the dust caps from the indoor and outdoor units, and the connecting pipe. 2. Align the joint counter of the connecting pipe with the proper indoor and outdoor joint conic surfaces and tighten the connecting nut manually. Then secure the connection with a wrench (Fig.16), applying the appropriate torque as listed on page 11 (Table Fig.17 1). 3. Remove the two valve core caps from the outdoor unit (Fig.17). 4. Turn on the high and low pressure valve cores with a socket wrench, then tighten the two valve core caps of the outdoor unit (Fig.17). 5. Finally, wrap the hot insulating cotton around the joints of the indoor and outdoor units.

Installation (Cont.) Installation checklist • Check and ensure that the installation place is solid and strong enough to support the weight of the unit. • Check and ensure that condensation water can easily drain away. • Check and ensure that in the vicinity of the unit: XX There is nothing that prevents ventilation or obstructs operation in front of the unit. XX There is suitable protection for the outdoor unit in case of direct exposure to sea breezes. XX There is a minimum distance of 1m between the indoor unit and remote controller and a TV or radio XX There are no flammable gas leaks. XX There is no oil splashing. • Check and ensure that the installation place does not increase the unit’s operation noise or vibration. If there is a possibility that vibration can be transmitted to the house, fix the unit by inserting vibration-proof pads between the unit and fittings. • Things left near the outlet and inlet of the outdoor unit cause malfunction or increased operation noise. Do not leave obstacles near the outlet and inlet. • If irregular sound is heard during operation, consult with the distributor of the unit using the information at the bottom of the page.
Inspection and maintenance According to the service conditions and operating environment, the inside of the air conditioner will become dirty after several seasons (3 to 5 years) of service, resulting in decreased operating performance. While the air conditioner may be still be used for a longer period, we recommend getting the unit professionally inspected and maintained during an off season, in addition to regular cleaning. To book a service call, contact our after sales support centre using the details at the bottom of the page.

Installation (Cont.) Quick connector installation instruction* * Only relevant for the installation of stainless quick connector pipes -- this section does not apply to the AK-9000-RC Air Conditioner • To expand the connecting pipe, hold one side then expand it following the right direction. • Make sure the angles have a radian at some extent while installing the stainless soft pipe. Angels need to be around, not bent (to the quick connecting spot and drilled point in the wall). • To prevent the stainless soft pipe from getting bent or stretched, always fix these soft connecting pipes while installing them.
Installation guide • To keep the allowed bending radius, take care when unwinding the packed soft pipes. Do not expand only one side of the pipes. • Use a semicircle pulley to maintain the appropriate bending radius. Extreme bending could damage the pipes. • Use a twisting wheel to avoid improper bending. Overlength soft pipes will lead to irregular bending. • Use a rigid elbow to keep the bending radius while soft pipes operating. Undersize bending will damage the soft pipe. • Make sure the soft pipe is not too short so the minimum bending radius can be maintained.
