The unit should be installed only by personnel certified by Mitsubishi Electric according to the instructions detailed in the Installation/Operation Manual. Improper installation may result in refrigerant leakage, water leakage, injury, electric shock, or fire. Periodically check the installation base for damage. If the unit is left on a damaged base, it may fall and cause injury. Remove packing materials from the unit before operating the unit. Note that some accessories may be taped to the unit. Properly install all accessories that are required. Failing to remove the packing materials or failing to install required accessories may result in refrigerant leakage, oxygen starvation, smoke, or fire. Consult your dealer and take appropriate measures to safeguard against refrigerant leakage and resultant oxygen starvation. An installation of a refrigerant gas detector is recommended. Any additional parts must be installed by qualified personnel. Only use the parts specified by Mitsubishi Electric. Take appropriate safety measures against wind gusts and earthquakes to prevent the unit from toppling over and causing injury. The unit should be installed on a surface that is strong enough to support its weight. Be sure to install the unit horizontally, using a level. If the unit is installed at an angle, it may fall and cause injury or cause water leakage. As an anti-freeze, use ethylene glycol or propylene glycol diluted to the specified concentration. The use of other types of anti-freeze solution may cause corrosion and resultant water leakage. The use of flammable anti-freeze may cause fire or explosion. CAUTION Pipe installation WARNING To prevent explosion, do not heat the unit with refrigerant gas in the refrigerant circuit. CAUTION To keep the ceiling and floor from getting wet due to condensation, properly insulate the pipes. Electrical wiring To reduce the risk of wire breakage, overheating, smoke, and fire, keep undue force from being applied to the wires. To reduce the risk of injury or electric shock, switch off the main power before performing electrical work. To reduce the risk of electric shock, smoke, or fire, install an inverter circuit breaker on the power supply to each unit. Do not install the unit on or over things that are vulnerable to water damage. When the indoor humidity exceeds 80% or if the drain water outlet becomes clogged, condensation may drip from the indoor unit onto the ceiling or floor. All drainage work should be performed by the dealer or qualified personnel according to the instructions detailed in the Installation Manual. Improper drainage work may cause rain water or drain water to enter the buildings and damage the furnishings. Check for refrigerant leakage at the completion of installation. If leaked refrigerant comes in contact with a heat source, toxic gas may be generated. Check that no substance other than the specified refrigerant (R744) is present in the refrigerant circuit. Infiltration of other substances may cause the pressure to rise abnormally high and cause the pipes to explode. Piping work should be performed by the dealer or qualified personnel according to the instructions detailed in the Installation Manual. Improper piping work may cause water leakage and damage the furnishings. All electric work must be performed by a qualified electrician according to the local regulations, standards, and the instructions detailed in the Installation Manual. Capacity shortage to the power supply circuit or improper installation may result in malfunction, electric shock, smoke, or fire. Properly secure the cables in place and provide adequate slack in the cables so as not to stress the terminals. Improperly connected cables may break, overheat, and cause smoke or fire. Use properly rated breakers and fuses (inverter breaker, Local Switch , or no-fuse breaker). The use of improperly rated breakers may result in malfunctions or fire. 4
