Safety Precautions
Read Safety Precautions Before Installation
Incorrect installation due to ignoring instructions can cause serious damage or injury.
The seriousness of potential damage or injuries is classified as either a WARNING or CAUTION.
This symbol indicates that ignoring instructions may cause death or serious injury.
WARNING
This symbol indicates that ignoring instructions may cause moderate injury to your person, or damage to your unit or other property.
CAUTION
This symbol indicates that you must never perform the action indicated.
WARNING
Do not modify the length of the power supply cord or use an extension cord to power the unit.
Do not share the electrical outlet with other appliances. Improper or insufficient power supply can cause fire or electrical shock.
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.
Do not allow children to play with the air conditioner. Children must be supervised around the unit at all times.
1.Installation must be performed by an authorized dealer or specialist. Defective installation can cause water leakage, electrical shock, or fire.
2.Installation must be performed according to the installation instructions. Improper installation can cause water leakage, electrical shock, or fire.
(In North America,installation must be performed in accordance with the requirement of NEC and CEC by authorized personnel only.)
3.Contact an authorized service technician for repair or maintenance of this unit.
4.Only use the included accessories, parts, and specified parts for installation. Using non-standard parts can cause water leakage, electrical shock, fire, and can cause the unit to fail.
5.Install the unit in a firm location that can support the unit’s weight. If the chosen location cannot support the unit’s weight, or the installation is not done properly, the unit may drop and cause serious injury and damage.
Page 4
WARNING
6.For all electrical work, follow all local and national wiring standards, regulations, and the
Installation Manual. You must use an independent circuit and single outlet to supply power. Do not connect other appliances to the same outlet. Insufficient electrical capacity or defects in electrical work can cause electrical shock or fire.
7.For all electrical work, use the specified cables. Connect cables tightly, and clamp them securely to prevent external forces from damaging the terminal. Improper electrical connections can overheat and cause fire, and may also cause shock.
8.All wiring must be properly arranged to ensure that the control board cover can close properly. If the control board cover is not closed properly, it can lead to corrosion and cause the connection points on the terminal to heat up, catch fire, or cause electrical shock.
9.In certain functional environments, such as kitchens, server rooms, etc., the use of specially designed air-conditioning units is highly recommended.
10.If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
11.This appliance can be used by children aged from 8 years and above and persons with reduced Physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.
CAUTION
For units that have an auxiliary electric heater, do not install the unit within 1 meter (3 feet) of any combustible materials.
Do not install the unit in a location that may be exposed to combustible gas leaks. If combustible gas accumulates around the unit, it may cause fire.
Do not operate your air conditioner in a wet room such as a bathroom or laundry room. Too much exposure to water can cause electrical components to short circuit.
1.The product must be properly grounded at the time of installation, or electrical shock may occur.
2.Install drainage piping according to the instructions in this manual. Improper drainage may cause water damage to your home and property.
Note about Fluorinated Gasses
1.This air-conditioning unit contains fluorinated gasses. For specific information on the type of gas and the amount, please refer to the relevant label on the unit itself.
2.Installation, service, maintenance and repair of this unit must be performed by a certified technician.
3.Product uninstallation and recycling must be performed by a certified technician.
4.If the system has a leak-detection system installed, it must be checked for leaks at least every 12 months.
5.When the unit is checked for leaks, proper record-keeping of all checks is strongly recommended.

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.

Step 2: Attach mounting plate to wall |
Step 3: Drill wall hole for connective piping |
The mounting plate is the device on which you will mount the indoor unit.
1.Remove the screw that attaches the mounting plate to the back of the indoor unit.
2.Place the mounting plate against the wall in a location that meets the standards in the Select Installation Location step. (See Mounting Plate Dimensions for detailed information on mounting plate sizes.)
3.Drill holes for mounting screws in places that:
•have studs and can support the weight of the unit
•correspond to screw holes in the mounting plate
4.Secure the mounting plate to the wall with the screws provided.
5.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.
You must drill a hole in the wall for refrigerant piping, the drainage pipe, and the signal cable that will connect the indoor and outdoor units.
1.Determine the location of the wall hole based on the position of the mounting plate. Refer to Mounting Plate Dimensions on the next page to help you determine the optimal position. The wall hole should have a 65mm (2.5in) diameter at least, and at a slightly lower angle to facilitate drainage.
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 (0.2-0.27in). This will ensure proper water drainage. (See Fig. 3.2)
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.
