PRECAUTIONS DURING INSTALLATION

WARNING

| ●      Do not reconstruct the unit.

Water leakage, fault, short circuit or fire may occur if you reconstruct the unit by yourself.

●      Please ask your sales agent or qualified technician for the installation of your unit. Water leakage, short circuit or fire may occur if you install the unit by yourself.

●      Please use the earth line.

Do not place the earth line near water or gas pipes, lightning-conductor, or the earth line of the telephone. Improper installation of the earth line may cause electric shock.

●      Be sure to use the specified piping set for R32. Otherwise, this may result in broken copper pipes or faults.

●     Do not use refrigerant other than the one indicated on the outdoor unit (R32) when installing, moving or repairing. Using other refrigerants may cause trouble or damage to the unit, and personal injury.

CAUTION

| ●     A circuit breaker should be installed depending on the mounting site of the unit. Without a circuit breaker, the danger of electric shock exists.

●     Do not install near locations where there is flammable gas. The outdoor unit may catch fire if flammable gas leaks around it.

●      Please ensure smooth flow of water when installing the drain hose.

●     Do not install the indoor unit in a machine shop or kitchen where vapour from oil or its mist flows to the indoor unit. The oil will deposit on the heat exchanger, thereby reducing the indoor unit performance and may deform and in the worst case, break the plastic parts of the indoor unit.

PRECAUTIONS DURING SHIFTING OR MAINTENANCE

| ●   Should an abnormal situation arise (like a burning smell), please stop operating the unit and turn off the circuit breaker. Contact your agent. Fault, short circuit or fire may occur if you continue to operate the unit under abnormal situations.

●   Please contact your agent for maintenance. Improper self-maintenance may cause electric shock and fire.

●   Please contact your agent if you need to remove and reinstall the unit. Electric shock or fire may occur if you remove and reinstall the unit yourself improperly.

●   If the supply cord is damaged, it must be replaced by the special cord obtainable at authorized service/parts centres.

●   If the air conditioner is not cool, one possible cause could be due to refrigerant leakage, so consult your dealer.

The refrigerant gas used in the air conditioner is harmless. But if refrigerant gas leaks into the room, harmful products are generated when in contact with fire from appliances such as a stove heater.

When there is refrigerant gas accumulation in the room, immediately stop the air conditioner. Open the windows for ventilation and contact your agent.

 | PRECAUTIONS DURING OPERATION
|

●    Avoid an extended period of direct air flow for your health.

●    Do not insert a finger, a rod or other objects into the air outlet or inlet. As the fan is rotating at a high speed, it will cause injury. Before cleaning, be sure to stop the operation and turn the breaker OFF.

●     Do not use any conductor as fuse wire, this could cause a fatal accident.

●    During thunderstorms, disconnect and turn off the circuit breaker.

●   Spray cans and other combustibles should not be located within a meter of the air outlets of both indoor and outdoor units. As a spray can’s internal pressure can be increased by hot air, a rupture may result.

PRECAUTIONS DURING OPERATION

|

●   The product shall be operated under the manufacturer’s specification and not for any other intended use.

●  Do not attempt to operate the unit with wet hands, this could cause a fatal accident.

●   When operating the unit with burning equipment, regularly ventilate the room to avoid oxygen insufficiency.

●   Do not direct the cool air coming out from the air-conditioner panel to face the household heating apparatus as this may affect the working of apparatus such as the electric kettle, oven etc.

●  Please ensure that the outdoor mounting frame is always stable, firm and without defects. If not, the outdoor unit may collapse and cause danger.

●  Do not splash or direct water to the body of the unit when cleaning it as this may cause a short circuit.

●  Do not use any aerosol or hair sprays near the indoor unit. This chemical can adhere on the heat exchanger fin and block the evaporation water flow to the drain pan. The water will drop on the tangential fan and cause water to splash out from the indoor unit.

●  Please switch off the unit and turn off the circuit breaker during cleaning, the high-speed fan inside the unit may cause danger.

●   Turn off the circuit breaker if the unit is not to be operated for a long period.

●  Do not climb on the outdoor unit or put objects on it.

●  Do not put a water container (like a vase) on the indoor unit to avoid water dripping into the unit. Dripping water will damage the insulator inside the unit and cause a short circuit.

●  Do not place plants directly under the airflow as it is bad for the plants.

●  When operating the unit with the door and windows opened, (the room humidity is always above 80%) and with the air deflector facing down or moving automatically for a long period, water will condense on the air deflector and drip down occasionally. This will wet your furniture. Therefore, do not operate under such conditions for a long time.

●  If the amount of heat in the room is above the cooling or heating capability of the unit (for example: more people entering the room, using heating pieces of equipment, etc.), the preset room temperature cannot be achieved.

●  This appliance can be used by children aged 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 the use of the appliance in a safe way and understand the hazards involved.

Information

Capabilities

Heating Capability

CAUTION: Do not use a stove or any other high temperature devices in proximity to the indoor unit.

• This room air conditioner utilizes a heat pump system that absorbs exterior heat and brings it into a room to be heated. As the ambient temperature gets lower, heating capability will also lower. In such a situation, the inverter work to increase compressor rpm to keep the unit’s heating capability from decreasing. If the unit’s heating performance is still unsatisfactory, other heating appliances should be used to augment this unit’s performance.
• The air conditioner is designed to heat an entire room so that it may take some time before you feel warm. Timer operation is recommended for effective preheating ahead of the desired time.

Cooling and Dehumidifying Capabilities

• If the heat present in a room exceeds the unit’s cooling capacity (for example, if there are many people in the room or other heating appliances are used), the preset room temperature may not be reached.

Refrigerant Information

• For the refrigerant charge information, please refer to the outdoor unit installation manual or specifi cation label.

MAINTENANCE

CAUTION: Cleaning and maintenance must be carried out only by qualifi ed service personnel. Before cleaning, stop operation and switch off the power supply.

PRE-FILTER

Clean the Pre-filter, as it removes dust inside the room. In case the Pre- filter is full of dust, the air flow will decrease and the cooling capacity will be reduced. Further, noise may occur. Be sure to clean the Pre-filter following the procedure below.

PROCEDURE

1. Open the front panel and remove the Pre-filter
   • Gently lift and remove the air purifying filters from the air purifying filter frame.
2. Vacuum dust from the Pre-filter and air purifying fi lter using vacuum cleaner. If there is too much dust, rinse under running tap water and gently brush it with soft bristle brush. Allow filters to dry in shade.
