Installation Instructions ­ Indoor unit
PRIOR TO INSTALLATION
Before installing the indoor unit, refer to the label on the product box to make sure that the model number of the indoor unit matches the model number of the outdoor unit.
Step 1: Select installation location Before installing the indoor 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:
Good air circulation Convenient drainage Noise from the unit will not disturb other
people Firm and solid–the location will not vibrate Strong enough to support the weight of the
unit A location at least one meter from all other
electrical devices (e.g., TV, radio, computer)
DO NOT install unit in the following locations:
Near any source of heat, steam, or combustible gas
Near flammable items such as curtains or clothing
Near any obstacle that might block air circulation
Near the doorway
In a location subject to direct sunlight

NOTE ABOUT WALL HOLE:
If there is no fixed refrigerant piping:
While choosing a location, be aware that you should leave ample room for a wall hole (see Drill wall hole for connective piping step) for the signal cable and refrigerant piping that connect the indoor and outdoor units. The default position for all piping is the right side of the indoor unit (while facing the unit). However, the unit can accommodate piping to both the left and right.
Refer to the following diagram to ensure proper distance from walls and ceiling:
15cm (5.9in) or more

12cm (4.72in) or more

12cm (4.72in) or more

2.3m (90.55in) or more
Step 2: Attach mounting plate to wall The mounting plate is the device on which you will mount the indoor unit.
Take out the mounting plate at the back of the indoor unit.

Secure the mounting plate to the wall with the screws provided. Make sure that mounting plate is flat against the wall.
NOTE FOR CONCRETE OR BRICK WALLS:
If the wall is made of brick, concrete, or similar material, drill 5mm- diameter (0.2in-diameter) holes in the wall and insert the sleeve anchors provided. Then secure the mounting plate to the wall by tightening the screws directly into the clip anchors.

5-7mm (0.2-0.275in)

Step 3: Drill wall hole for connective piping
1. Determine the location of the wall hole based on the position of the mounting plate. Refer to Mounting Plate Dimensions.
2. Using a 65mm (2.5in) or 90mm(3.54in) (depending on models )core drill, drill a hole in the wall. Make sure that the hole is drilled at a slight downward angle, so that the outdoor end of the hole is lower than the indoor end by about 5mm to 7mm (0.2-0.275in). This will ensure proper water drainage.
3. Place the protective wall cuff in the hole. This protects the edges of the hole and will help seal it when you finish the installation process.

CAUTION
When drilling the wall hole, make sure to avoid wires, plumbing, and other sensitive components.

Step 4: Prepare refrigerant piping
The refrigerant piping is inside an insulating sleeve attached to the back of the unit. You must prepare the piping before passing it through the hole in the wall. 1. Based on the position of the wall hole relative
to the mounting plate, choose the side from which the piping will exit the unit. 2. If the wall hole is behind the unit, keep the knock-out panel in place. If the wall hole is to the side of the indoor unit, remove the plastic knock-out panel from that side of the unit. This will create a slot through which your piping can exit the unit. Use needle nose pliers if the plastic panel is too difficult to remove by hand. 3. Groove has been made in the knock-out panel in order to cut it conveniently. The size of the slot is determined by the diameter of piping.
Knock-out Panel
4. If existing connective piping is already embedded in the wall, proceed directly to the Connect Drain Hose step. If there is no embedded piping, connect the indoor unit’s refrigerant piping to the connective piping that will join the indoor and outdoor units. Refer to the Refrigerant Piping Connection section of this manual for detailed instructions.
NOTE ON PIPING ANGLE Refrigerant piping can exit the indoor unit from four different angles:Left-hand side,Right-hand side, Left rear, Right rear.

Step 5:Connect drain hose
By default, the drain hose is attached to the lefthand side of unit (when you’re facing the back of the unit). However, it can also be attached to the right-hand side. To ensure proper drainage, attach the drain hose on the same side that your refrigerant piping exits the unit. Attach drain hose extension (purchased separately) to the end of drain hose.
Wrap the connection point firmly with Teflon tape to ensure a good seal and to prevent leaks.
For the portion of the drain hose that will remain indoors, wrap it with foam pipe insulation to prevent condensation. Remove the air filter and pour a small amount of water into the drain pan to make sure that water flows from the unit smoothly.
NOTE ON DRAIN HOSE PLACEMENT
Make sure to arrange the drain hose according to the follo.wing figures.

CORRECT
Make sure there are no kinks or dent in drain hose to ensure proper drainage.

NOT CORRECT
Kinks in the drain hose will create water traps.

Refrigerant Piping Connection

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

Note on Pipe Length

The length of refrigerant piping will affect the performance and energy efficiency of the unit. Nominal efficiency is tested on units with a pipe length of 5 meters (16.5ft)( In North America, the standard pipe length is 7.5m (25′). A minimum pipe run of 3 metres is required to minimise vibration & excessive noise. In special tropical area, for the R290 refrigerant models, no refrigerant can be added and the maximum length of refrigerant pipe should not exceed 10 meters(32.8ft).
Refer to the table below for specifications on the maximum length and drop height of piping.

Connection Instructions ­ Refrigerant Piping

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.

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.

6. Place flaring tool onto the form. 7. Turn the handle of the flaring tool clockwise
until the pipe is fully flared. 8. Remove the flaring tool and flare form, then
inspect the end of the pipe for cracks and even flaring.
Step 4: Connect pipes
When connecting refrigerant pipes, be careful not to use excessive torque or to deform the piping in any way. You should first connect the low-pressure pipe, then the high-pressure pipe.
MINIMUM BEND RADIUS
When bending connective refrigerant piping, the minimum bending radius is 10cm.

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 edge of the flare form in accordance with the dimensions shown in the table below.

Note on Adding Refrigerant
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 7.5m (25′). In other areas, the standard pipe length is 5m (16`). The refrigerant should be charged from the service port on the outdoor unit’s low pressure valve. The additional refrigerant to be charged can be calculated using the following formula:
