Congratulations Contents Congratulations and thank you for choosing our Inverter split system room air conditioner. We are sure you will find your new air conditioner a pleasure to use. Before you use the air conditioner, we recommend that you read through the entire user manual, which provides the description of the air conditioner and its functions. Important Safety Instructions..................................................
Important safety instructions Please read this installation manual and the user manual before installation and carefully store in a handy place for later reference. Inside you will find many helpful hints on how to install and test the air conditioner properly. Incorrect installation due to ignoring this instruction may cause harm or damage, which may not be covered by warranty.
Choosing a location to mount unit Indoor unit Outdoor unit • Do not install the unit near any heat source, ammable gas or steam. • • Choose a location where the air circulation is good, and where there are no obsticles blocking the air ow. If an awning is built over the unit to prevent direct sunlight or rain, be careful that heat radiation from the condenser is not obstructed. • Select a place that will be convenient to run a drain to suitable location outside.

The installation plate should be installed on a wall which can support the weight of the indoor unit.
Indoor unit installation Drilling the wall 1. Fig. 3 Indoor Wall Outdoor Choose the hole position to be either on the left or right side of the installation plate and mark the position according to the dimensions shown in figure 2. Note most simple installation is with hole on the right side. 2. Drill the piping hole with a hole core drill of the following size: 65mm for models: KSV25CRH, KSV25HRH, KSD25HRH, KSV35CRH, KSV35HRH, KSD35HRH.
Indoor unit installation Drain piping Connect the cable to the indoor unit 1. Run the drain hose as shown in figure 6, ensuring it has a constant downward fall. 2. The installer must supply a suitable drain hose extension to run from the indoor unit drain hose to the desired drain location. The drain hose extension should be fitted and sealed tightly with the indoor unit drain hose, and secured in place with vinyl tape.

Outdoor unit installation WARNING caution Drain elbow installation • Install the outdoor unit on a rigid base to prevent excessive noise level and vibration. • Choose an outdoor unit location where the air outlet direction is not blocked, and the clearances as per the assembly diagram (figure 1) are followed.
Outdoor unit installation Refrigerant pipe connection NOTE: • The connectors used to join the indoor and outdoor refrigeration pipes must be located outside. They cannot be located inside or within a wall cavity where refrigerant may build up in the case of a leak. • Refrigeration pipe length will affect the capacity and energy efficiency of the unit. The nominal efficiency is tested based on the pipe length of 5 meters.
Outdoor unit installation Flaring work Fig. 12 " 90° ✓ ✗ Oblique ✗ Roughness ✗ Burr TIPS & INFORMATION important For installer It is critical that the installer follows the correct flaring procedure using the right tools to produce good quality flares in order to ensure installation without refrigerant gas leaks. Pipe Fig. 13 Reamer Service calls caused by poor installation are the responsibility of the installer, and these service calls will be referred back to the installer accordingly.

Outdoor unit installation Electrical connection Magnetic ring installation Wiring diagram Please note that different models are supplied with a different combination of magnetic rings that must be installed by a licensed electrician. These magnetic rings (if required) help to minimise electro magnetic interference, which if not installed correctly may impact television and radio operation.
Test running Air purging Air and other foreign matter in the refrigerant circuit causes abnormal pressure rise, which may result in equipment damage and even injury. Therefore, the indoor unit and tubing between the indoor and outdoor unit must be leak tested and evacuated to remove any non condensable and moisture from the system. NOTE: Any brazed connections must be completed before evacuation and prior to release of any refrigerant into the refrigeration system. Low temperature solder must not be used.
Outdoor unit installation • Make sure the refrigerant added into the air conditioner is liquid form. Fig. 20 Outdoor unit Caution in handling the service valve • • A. Low pressure valve (3-way) Refrigerant gas side. C Gas side Liquid side To open the service valve, remove the cap then open the valve stem using an Allen key until it hits the stopper, do not try to open it further. Service valve B.
Electrical and gas leak check Electrical safety check Operation test Perform the electric safe check after completing installation: After confirming the electrical safety has passed and confirmed there are no gas leaks, follow the below steps to complete an operation test: 1. 2. Earth connection - Check the earth connection visually and with a multi meter following national wiring rules to confirm good earth connection of both the indoor unit and the outdoor unit.
Information servicing Checks to the area Checks to the refrigeration equipment Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimised. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system. Where electrical components are being changed, they shall be fit for the purpose and to the correct specification.
Information servicing Repairs to sealed components Removal and evacuation 1. During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
Information servicing Charging procedures k) In addition to conventional charging procedures, the following requirements shall be followed: Labelling • Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them. • Cylinders shall be kept upright. • Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
