Warning: : Indicates a part which must be grounded. Describes precautions that must be observed to prevent danger of injury or death to the user. Warning: Caution: Carefully read the labels affixed to the main unit. Describes precautions that must be observed to prevent damage to the unit. Before installing the unit, make sure you read all the “Safety precau tions”. Please report to your supply authority or obtain their consent before connecting this equipment to the power supply system. After installation work has been completed, explain the “Safety Precautions,” use, and maintenance of the unit to the customer according to the information in the Operation Manual and perform the test run to ensure normal operation. Both the Installation Manual and Operation Manual must be given to the user for keeping. Warning: • Ask a dealer or an authorized technician to install the unit. • For installation work, follow the instructions in the Installation Manual and use tools and pipe components specifically made for use with refrigerant specified in the outdoor unit installation manual. • The unit must be installed according to the instructions in order to minimize the risk of damage from earthquakes, typhoons, or strong winds. An incorrectly installed unit may fall down and cause damage or injuries. • The unit must be securely installed on a structure that can sustain its weight. • If the air conditioner is installed in a small room, measures must be taken to prevent the refrigerant concentration in the room from exceeding the safety limit in the event of refrigerant leakage. Should the refrigerant leak and cause the concentration limit to be exceeded, hazards due to lack of oxygen in the room may result. • Ventilate the room if refrigerant leaks during operation. If refrigerant comes into contact with a flame, poisonous gases will be released. • All electric work must be performed by a qualified technician according to local regulations and the instructions given in this manual. • Use only specified cables for wiring. • The terminal block cover panel of the unit must be fi rmly attached. • Use only accessories authorized by Mitsubishi Electric and ask a dealer or an authorized technician to install them. • The user should never attempt to repair the unit or transfer it to another location. • After installation has been completed, check for refrigerant leaks. If refrigerant leaks into the room and comes into contact with the fl ame of a heater or portable cooking range, poisonous gases will be released. 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, fi re 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.
