Page 3: Introduction
Introduction 1. Introduction 1.2 Safety Cautions 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. - Page 4 Introduction Warning 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.
- Page 5 Introduction Warning Be sure to use an exclusive power circuit for the equipment, and follow the technical standards related to the electrical equipment, the internal wiring regulations and the instruction manual for installation when conducting electrical work. Insufficient power circuit capacity and improper electrical work can cause an electrical shock or fire. Be sure to use the specified cable to connect between the indoor and outdoor units.
- Page 6 Introduction Do not install the equipment in a place where there is a possibility of combustible gas leaks. If a combustible gas leaks and remains around the unit, it can cause a fire. Be sure to install the packing and seal on the installation frame properly. If the packing and seal are not installed properly, water can enter the room and wet the furniture and floor.
- Page 7 Introduction Check the grounding, and repair it if the equipment is not properly grounded. Improper grounding can cause an electrical shock. Be sure to measure the insulation resistance after the repair, and make sure that the resistance is 1 M ohm or higher.
