Installing, starting up, and servicing
Only trained, qualified installers and service mechanics should install,
When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment.
Follow all safety codes. Wear safety glasses and work gloves. Keep quenching cloth and fire extinguisher nearby when brazing. Use care in handling, rigging, and setting bulky equipment.
Read these instructions thoroughly and follow all warnings or cautions included in literature and attached to the unit. Consult local building codes and National Electrical Code (NEC) for special requirements. Recognize safety information. This is the
DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.
WARNING
•Ask an authorized dealer or qualified installation professional to install/maintain the air conditioner. Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
•Be sure to ground the equipment
Improper grounding may cause an electric shock.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires.
•Turn off the circuit breaker before attempting any electrical work and maintenance. Make sure the circuit breaker is off. Failure to do so may cause electric shock.
Use an exclusive power circuit for the air conditioner. Use the rated voltage.
•When moving the air conditioner for installation to another place, be very careful not to allow the specified refrigerant (R410A) to become mixed with any other gaseous body into the refrigeration cycle.
If air or any other gas mixes with the refrigerant, the gas pressure in the refrigeration cycle will become abnormally high and it may result in the pipe bursting or personal injuries.
•Do not modify this unit by removing any of the safety guards or by
•Do not touch the intake or aluminium fins of the outdoor unit. Doing so may result in injury.
•Tighten the flare nut with a torque wrench in the specified manner.
Excessive tightening of the flare nut may cause a crack in the flare nut after a long period, which may result in refrigerant leakage.
•Install the air conditioner securely in a location where the base can sustain the weight of the unit adequately.
•If refrigerant gas has leaked during the installation work, ventilate the room immediately. If the leaked refrigerant gas comes in contact with fire, noxious gas may be generated.
•After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas may be generated.
•Electrical work must be performed by a qualified electrician in accordance with the NEC or local code. Make sure the air conditioner uses an exclusive power supply.
An insufficient power supply capacity or inappropriate installation may cause fire.
•Use only the specified wiring during the unit installation. Ensure that all terminals are securely fixed, so preventing any external forces having a negative effect on the terminals.
