Safety Precautions

Read and Understand All Safety Precautions Prior to Installation

Improper installation due to negligence of instructions may result in serious damage or injury. The magnitude of potential damages or injuries is classified as either a WARNING or a CAUTION.

This symbol indicates that ignoring the related instructions may cause death, or

serious

This symbol indicates that ignoring the related instructions may cause moderate injury to nearby persons, and/or damage to your appliance or other property.

injury.

This symbol indicates that

DANGER

you must never perform the action shown.

WARNING

Do not power the system using an extension cable or with wiring smaller than the specified gauge. Do not share the electrical circuit with other appliances. Improper or insufficient power supply can cause undesirable operation, fire, or electrical shock.

When connecting refrigerant piping, do not let any 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 also cause explosion and injury, as well as permanent equipment failure. Remember: No dust, humidity or air is allowed to enter.

Do not allow children to play with or around the air conditioner. Children near the unit must be supervised at all times.

Installation must be performed by a licensed and trained technician. Defective installation can cause water leakage, electrical shock, or fire. The usage of proper tools is a requirement.

Installation must be performed according to the installation instructions. Improper installation can cause water leakage, undesired performance, electrical shock, or fire. (In North America, installation must be performed in accordance with the requirements of NEC and CEC, by authorized personnel only.)

Contact a qualified and licensed HVAC technician for any repairs or maintenance of this unit.

Only use the included accessories, parts, and specified items for installation. Using non-standard

parts can cause water leakage, electrical shock, fire, and can cause total unit failure.

Install the unit on top of a firm structure that can fully support its weight. If the chosen location cannot support the unit’s weight, or the installation is not done properly, the unit may fall and cause serious injury and damage.

WARNING

For all electrical work, follow all local and national wiring standards, regulations, and especially this Installation Manual. You must use an independent circuit and a dedicated breaker to supply power. Do not connect other appliances to the same circuit. Insufficient electrical capacity or defects in electrical work can cause electrical shock or fire.

For all electrical work, use the specified cables. Connect cables tightly, and clamp them securely to prevent external forces from damaging the terminals. Improper electrical connections can overheat and cause fire, and may also cause shock.

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.

In certain functional environments, such as kitchens, server rooms, etc., the use of specially designed

9. air-conditioning units is highly recommended. This is intended as a general comfort cooling system.

If the supply cord is damaged, it must be replaced by a certified service agent or similarly qualified

10. technicians, in order to avoid a hazard.

11.

This appliance can be used by children aged 8 years and above, as well as persons with reduced physical, sensory, or mental capabilities, or lack of experience or 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 or near the appliance. Cleaning and user maintenance shall not be done or attempted by children or untrained personnel without proper 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 gas accumulates around the unit, it may cause fire.

Do not operate your air conditioner in a highly humid space, such as bathrooms or laundry rooms. Exposure to high humidity or water can cause electrical components to short circuit.

The product must be properly grounded at the time of installation, else electrical shock may occur.

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

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.

Installation, service, maintenance, and repair of this unit must be performed by a certified HVAC technician.

3. Product uninstallation and recycling must be performed by a certified HVAC technician.

Replacement of Batteries

Remove the battery cover from the rear of the remote controller, by sliding it downward in the direction of the arrow as depicted below. Install batteries according to the depicted directions (+ and -) as shown on the remote controller. The cover then slides back into place.

Use 2x AAA batteries. Do not use re-chargeable batteries. Replace old batteries with new ones of the same type when the display is no longer legible. Do not dispose of batteries as unsorted municipal waste. Disposal of such waste separately for special treatment is necessary. If the system will not be used for a long time, remove batteries to prevent leakage.

Note

Please remove batteries to avoid

leakage damage when not being used for a long time.

Configuring Remote Controller Settings (some models)

Depending on the system, the control type (Cooling Only or Heat Pump) must be set after a battery swap is done. As soon as the batteries are inserted, the symbols and will begin flashing. Operate as below:

• When the symbol is displayed, push any button to set the control type to Cooling Only.

• When the symbol is displayed, push any button to set the control type to Heat Pump.

Note: If the remote control is used to set the control type to Cooling Only, the heating function cannot be activated in systems with a heat pump. To modify or reset this setting, first remove the batteries and then reinstall and repeat.

The temperature display can be set to show degrees in either °C or °F by doing the following:

1. Press and hold the TURBO button for 5+ seconds to activate the change prompt.

2. Repeat this process once more to switch between °C and °F options.

3. Release the button, and the setting will be active after 5 seconds have elapsed.

Operating the Remote Controller Successfully and Safely

• Ensure no objects come between the remote controller and signal

receptor of indoor unit.

• Keep the remote at least 3 ft away from televisions and other

electrical appliances.

• Always direct the remote controller toward the air conditioner.

• Don’t leave the remote exposed to sunrays.

Regarding the Airflow of the Indoor Unit

The air that is pulled in by the fan (the “return air”) enters the grille and is passed through the filter. It is then cooled/dehumidified/heated through the heat exchanger.

The direction of the air output is manipulated up and down by the motorized louver, and left to right via manually controlled vertical deflectors. Some models may come with “dual-swing” capability, which offers both a horizontal and vertical motorized air flow swing.

Controlling the System’s Airflow

1. Pressing the SWING buttons activate the louver.

Filter

Heat

Fan

• Press the button to trigger the horizontal flaps to swing up and down. Press this button again to stop swing movement at the current angle.

• Press the button to trigger the vertical flaps to swing left and right. Press this button again to stop swing movement at the current angle.

2. If the vertical deflectors (which are located underneath the flaps) are adjusted manually, they can be used to fix the airflow in a certain vertical position before turning the system on.

CAUTION

• Do not manipulate the louvers themselves

manually, or serious damage may occur.

• Deflector adjustments should be made

only when the system is switched off.

• Never poke fingers, sticks, or other

objects into the air inlet/outlet vents.
