1. Safety precautions 1.1. Before installation (Environment) Caution: • Do not use the unit in an unusual environment. If the air conditioneris 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 explo sion 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. 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 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 condensa tion. If the refrigerant pipe is not properly insulated, condensation will be formed. 1.3. Before electric work Caution: • Be sure to install 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. 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. 2. Installation location • 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. • Place thermal insulation on the pipes to prevent condensation. If the drain pipe 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. EN • 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. • 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.
