When Wiring

When Transporting

Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum ﬁns on the air conditioner can cut your ﬁngers.

When Installing…

Select an installation location which is rigid and strong enough to support or hold the unit, and select a location for easy maintenance.

…In a Room

Properly insulate any tubing run inside a room to prevent “sweating” that can cause dripping and water damage to walls and ﬂoors.

Keep the ﬁre alarm and the air

CAUTION

…In Moist or Uneven Locations

Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents

water damage and abnormal vibration.

…In an Area with High Winds

Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air bafﬂe.

…In a Snowy Area (for Heat Pump-type Systems)

Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents.

outlet at least 5 feet (1.5 m) away from the unit.

When Connecting Refrigerant Tubing

•Ventilate the room well, in the event that is refrigerant gas leaks during the installation. Be careful not to allow contact of the refrigerant gas with a ﬂame as this will cause the generation of poisonous gas.

•Keep all tubing runs as short as possible.

•Use the ﬂare method for connecting tubing.

•Apply refrigerant lubricant to the matching surfaces of

the ﬂare and union tubes before connecting them, then tighten the nut with a torque wrench for a leak-free connection.

•Check carefully for leaks before starting the test run.

WARNING

•When performing piping work do not mix air except for speciﬁed refrigerant (R410A) in refrigeration cycle. It causes capacity down, and risk of explosion and injury due to high

tension inside the refrigerant cycle.

•Check for a leaking refrigerant! Refrigerant gas may produce a toxic gas if it

comes in contact with ﬁre.

•Do not add or replace refrigerant other than speciﬁed type. It may cause product damage, burst and injury etc.

•Do not leak refrigerant while piping work for an installation or re-installation, and while repairing refrigeration parts. Handle liquid refrigerant carefully as it may cause

frostbite.

When Servicing

•Turn the power OFF at the main power box (mains) before opening the unit to check or repair electrical parts and wiring.

•Keep your ﬁngers and clothing away from any moving parts.

•Clean up the site after you ﬁnish, remembering to check that no metal scraps or bits of wiring have been left inside the unit being serviced.

CAUTION

•Do not touch the air inlet or the sharp aluminum ﬁns of the outdoor unit. You may get injured.

•Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped refrigerant gas, on contact with ﬁre or heat, can produce dangerously toxic gas.

•Conﬁrm after installation that no refrigerant gas is leaking. If the gas comes in contact with a burning stove, gas water heater, electric room heater or other heat source, it can cause the generation of poisonous gas.

WARNING

•This product must not be modiﬁed or disassembled under any circumstances. Modiﬁed or disassembled unit may cause ﬁre, electric shock or injury.

•Do not clean inside the indoor and outdoor units by users. Engage authorized dealer or specialist for cleaning.

•In case of malfunction of this appliance, do not repair by yourself. Contact to the sales dealer or service dealer for a repair.

Check of Density Limit

The room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out, its density will not exceed a set limit.

The refrigerant (R410A), which is used in the air conditioner, is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws imposed to protect the ozone layer. However, since it contains more than air, it poses the risk of suffocation if its density should rise excessively. Suffocation from leakage of refrigerant is almost non-existent. With the recent increase in the number of high density buildings, however, the installation of multi air conditioner systems is on the increase because of the need for effective use of ﬂoor space, individual control, energy conservation by curtailing heat and carrying power, etc. Most importantly, the multi air conditioner system is able to replenish a large amount of refrigerant compared to conventional individual air conditioners. If a single unit of the multi air conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its density does not reach the limit (and in the event of an emergency, measures can be made before injury can occur).

Others

CAUTION

•Do not sit or step on the unit, you may fall down accidentally.

•Do not touch the air inlet or the sharp aluminum ﬁns of the outdoor unit. You may get injured.

•Do not stick any object into the FAN CASE. You may be injured and the unit may be damaged.

ASHRAE and the International Mechanical Code of the ICC as well as CSA provide guidance and deﬁne safeguards related to the use of refrigerants, all of which deﬁne a Refrigerant Concentration Level (RCL) of 25 pounds (11.3 kg) per 1,000 cubic feet (28.3 m3) for R410A refrigerant. For additional guidance and precautions related to refrigerant safety, please refer to the following documents:

locations where the remote controller will be splashed with water or affected by dampness or humidity.

●

installing the remote controller behind curtains or furniture.

●

locations where high-frequency emissions are generated.

DO:

●

select an appropriate position from which every corner of the room can be uniformly cooled.

●

select a location where the ceiling is strong enough to support the weight of the unit.

WARNING

●

select a location which can support a load that is four times the indoor unit weight.

●

select a location where tubing and drain pipe have the shortest run to the outdoor unit.

●

allow room for operation and maintenance as well as unrestricted air flow around the unit.

●

install the unit within the maximum elevation difference above or below the outdoor unit and within a total tubing length (L) from the

outdoor unit as detailed in the installation instructions packed with the outdoor unit.

●

allow room for mounting the remote controller about 3.3 ft. (1 m) off the floor, in an area that is not in direct sunlight nor in the flow of cool

air from the indoor unit.
