|
|
|
||
• After reading this manual, be sure to keep it together with the instruction manual in a handy place . |
|
WARNING
Do not install it yourself (customer).
•Incomplete installation could cause injury due to fire, electric shock, the unit falling or a leakage of water. Consult the dealer from whom you purchased the unit or special installer.
Install the unit securely in a place which can bear the weight of the unit.
•When installed in an insufficient strong place, the unit may fall and result in serious problem.
Use the specified wires to connect the indoor and the outdoor units securely and attach the wires firmly to the terminal board connecting sections so the stress of the wires is not applied to the sections.
• Incomplete connecting and fixing could cause fire.
Check that the refrigerant gas do not leak after installation is completed.
Perform the installation securely referring to the installation manual.
•Incomplete installation could cause a personal injury due to fire, electric shock, the unit falling or a leakage of water.
Perform electrical work according to the installation manual and be sure to use an exclusive circuit.
•If the capacity of the power circuit is insufficient or there is incomplete electrical work, it could result in a fire or an electric shock.
Attach the electrical part cover to the indoor unit and the service panel to the outdoor unit securely.
•Not being attached securely, it may cause electric problem or electric shock due to dust or water etc.
Be sure to use the part provided or specified parts for the installation work.
•The use of defective parts could cause an injury or leakage of water due to a fire, electric shock, the unit falling, etc.
CAUTION
Perform grounding
•Do not connect the ground wire to a gas pipe, water pipe arrester or telephone ground wire. Defective grounding could cause an electric shock.
Perform the drainage/piping work securely according to the installation manual.
•If there is a defect in the drainage/piping work, water could drop from the unit and household goods could be wet and damaged.
Do not install the unit in a place where an inflammable gas leaks.
•If gas leaks and accumulates in the area surrounding the unit, it could cause an explosion.

NOTE:
• Avoid the following installatation location.
1.Such places as restaurants and kitchen where considerable amount of oil steam and flour is generated.
These may cause heat exchange efficiency reduction, or water drops, drain pump mal-function. In these cases, take the following actions;
•Make sure that ventilation fan is enough to cover all noxious gases from this place.
•Ensure the enough distance from cooking room to install the air conditioner in such a place where it may not suck oily steam.
Air conditioner
Take enough distance
Use the ventilation fan for smoke-collecting hood with sufficient
capacity.
Cooking table
2.Avoid installng air conditioner in such circumstances where cooking oil or iron powder is generated.
3.Avoid places where inflammable gas is generated.
4.Avoid place where noxious gas is generated.
5.Avoid places near high frequency generators.

4.Remote Controller Installation
•Although the room temperature sensor is in the indoor unit, the remote controller should be installed in such places away from direct sunlight and high humidity.
Installation of the remote controller
•Select places that are not splashed with water.
•Select control position after receiving customer approval.
•The room temperature sensor is built in the indoor unit.
•This remote controller equipped with liquid crystal display. If this position is higher or lower, display is difficult to see.(The standard height is 1.2 ~ 1.5m high)
Routing of the remote controller cord
•Keep the remote controller cord away from the refrigerant piping and the drain piping.
•To protect the remote controller cord from electrical noise, place the cord at least 5cm away from other power cables (audio equipment, television set, etc.)
•If the remote controller cord is secured to the wall, provide a trap at the top of the cord to prevent water droplets from running.
