1. Safety precautions

1.1. Before installation (Environment) Caution:
· Do not use the unit in an unusual environment. If the air conditioner is installed in areas exposed to steam, volatile oil (including machine oil), or sulfuric gas, areas exposed to high salt content such as the seaside, the performance can be significantly reduced and the internal parts can be damaged.
· Do not install the unit where combustible gases may leak, be produced, flow, or accumulate. If combustible gas accumulates around the unit, fire or explosion may result.
· Do not keep food, plants, caged pets, artwork, or precision instruments in the direct airflow of the indoor unit or too close to the unit as these items
can be damaged by temperature changes or dripping water.

· When the room humidity exceeds 80% or when the drainpipe is clogged, water may drip from the indoor unit. Do not install the indoor unit where
such dripping can cause damage.
· When installing the unit in a hospital or communications office, be prepared for noise and electronic interference. Inverters, home appliances, high- frequency medical equipment, and radio communications equipment can cause the air conditioner to malfunction or breakdown. The air conditioner may also affect medical equipment, disturbing medical care, and communications equipment, harming the screen display quality.

1.2. Before installation or relocation Caution:
· Be extremely careful when transporting the units. Two or more persons are needed to handle the unit as it weighs 20 kg, 44lbs or more. Do not grasp the packaging bands. Wear protective gloves as you can injure your hands on the fins or other parts.
· Be sure to safely dispose of the packaging materials. Packaging materials, such as nails and other metal or wooden parts may cause stabs or other injuries.
· Thermal insulation of the refrigerant pipe is necessary to prevent condensation. If the refrigerant pipe is not properly insulated, condensation
will be formed. · Place thermal insulation on the pipes to prevent condensation. If the drainpipe
is installed incorrectly, water leakage and damage to the ceiling, floor, furniture, or other possessions may result.

· Do not clean the air conditioner unit with water. Electric shock may result. · Tighten all flare nuts to specification using a torque wrench. If tightened too
much, the flare nut can break after an extended period. · If the unit is run for long hours when the air above the ceiling is at high
temperature/high humidity (dew point above 26 ºC, 79 ºF), dew condensation may be produced in the indoor unit or the ceiling materials. When operating the units in this condition, add insulation material (10-20 mm, 25/64-25/32 inch) to the entire surface of the unit and ceiling materials to avoid dew condensation.

1.3. Before electric work Caution:
· Be sure to install molded case circuit breakers. If not installed, electric shock may result.
· For the power lines, use standard cables of sufficient capacity. Otherwise, a short circuit, overheating, or fire may result.
· When installing the power lines, do not apply tension to the cables.

· Be sure to ground the unit. If the unit is not properly grounded, electric shock may result.
· Use circuit breakers (ground fault interrupter, isolating switch (+B fuse), and molded case circuit breaker) with the specified capacity. If the circuit breaker capacity is larger than the specified capacity, breakdown or fire may result.

1.4. Before starting the test run Caution:
· Turn on the main power switch more than 12 hours before starting operation. Starting operation just after turning on the power switch can severely damage the internal parts.
· Before starting operation, check that all panels, guards and other protective parts are correctly installed. Rotating, hot, or high voltage parts can cause injuries.

· Do not operate the air conditioner without the air filter set in place. If the air
filter is not installed, dust may accumulate and breakdown may result. · Do not touch any switch with wet hands. Electric shock may result. · Do not touch the refrigerant pipes with bare hands during operation. · After stopping operation, be sure to wait at least five minutes before turning off
the main power switch. Otherwise, water leakage or breakdown may result.

· Drain pipes should have an inclination of 1/100 or more. · For extension of the drain pipe, use a soft hose (inner dia. 15 mm, 19/32 inch)
available on the market or hard vinyl chloride pipe (VP-16 mm, 5/8 inch/O.D. ø22 mm, ø55/64 inch PVC TUBE). Make sure that there is no water leakage from the connections. · Do not put the drain piping directly in a drainage ditch where sulphuric gas may be generated. · When piping has been completed, check that water flows from the end of the drain pipe.
Caution:
The drain pipe should be installed according to this Installation Manual to ensure correct drainage. Thermal insulation of the drain pipes is necessary to prevent condensation. If the drain pipes are not properly installed and insulated, condensation may drip on the ceiling, floor or other possessions.
