Introduction SiENBE37-704 1. Introduction 1.1 Safety Cautions Cautions and Warnings ! Be sure to read the following safety cautions before conducting repair work. ! The caution items are classified into Warning and Caution. The Warning items are especially important since they can lead to death or serious injury if they are not followed closely. The Caution items can also lead to serious accidents under some conditions if they are not followed.
SiENBE37-704 Introduction Caution Do not repair the electrical components with wet hands. Working on the equipment with wet hands can cause an electrical shock. Do not clean the air conditioner by splashing water. Washing the unit with water can cause an electrical shock. Be sure to provide the grounding when repairing the equipment in a humid or wet place, to avoid electrical shocks. Be sure to turn off the power switch and unplug the power cable when cleaning the equipment.
Introduction SiENBE37-704 Warning Be sure to use the specified cable to connect between the indoor and outdoor units. Make the connections securely and route the cable properly so that there is no force pulling the cable at the connection terminals. Improper connections can cause excessive heat generation or fire. When connecting the cable between the indoor and outdoor units, make sure that the terminal cover does not lift off or dismount because of the cable.
SiENBE37-704 Introduction Caution Check to see if the parts and wires are mounted and connected properly, and if the connections at the soldered or crimped terminals are secure. Improper installation and connections can cause excessive heat generation, fire or an electrical shock. If the installation platform or frame has corroded, replace it. Corroded installation platform or frame can cause the unit to fall, resulting in injury.
