SAFETY OVERVIEW

ENGLISH

Read These Safety Precautions

Be sure to read the safety precautions before conducting work. The items are classified into “Warning” and “Caution.” The “Warning" items are especially important since they can lead to death or serious injury if not followed closely. Under certain conditions, the "Caution" items can also lead to accident or injury if they are not followed. Therefore, be sure to observe all safety precautions listed here.

∆ This symbol means be careful when doing this procedure or touching this equipment.

ᴏ This symbol indicates a prohibited action.

• This symbol means that an action must be taken; the action will be listed next to the symbol.

After the repair work is complete, be sure to conduct a test operation to ensure that the equipment operates properly; explain the safety precautions for operating the equipment to the customer.

Warning

Disconnect the power cable from electrical supply before disassembling equipment for repair.

If the refrigerant discharges during the repair work, DO NOT touch the discharging refrigerant. The refrigerant can cause frostbite.

Before disconnecting the suction or discharge pipe of the compressor at the brazed connections, recover the refrigerant in a well-ventilated area. If refrigerant remains inside the compressor, the refrigerant or the refrigerating machine oil will discharge when the pipe is disconnected and may cause injury.

If the refrigerant leaks during the repair work, ventilate the area. The refrigerant can generate toxic gases when it contacts flames.

The step-up capacitor supplies high-voltage electricity to the electrical components of the outdoor unit. Be sure to discharge the capacitor completely before conducting repair work. A charged capacitor can cause electrical shock.

Be sure to use parts listed in the service parts of the applicable model and appropriate tools to conduct repair work. Never attempt to modify

the equipment. The use of inappropriate parts or tools can cause electrical shock, excessive heat generation, or fire.

When relocating the equipment make sure that the new installation site has sufficient strength to withstand the weight of the equipment. If the new installation site does not have sufficient strength and if the installation work is not conducted securely, the equipment can fall and cause injury.

Be sure to install the product correctly by using the standard installation frame provided. Incorrect use of the installation frame and improper installation can cause equipment to fall, resulting in injury.

Do not repair the electrical components with wet hands. Working on equipment with wet hands can cause electrical shock.

Do not clean the equipment by splashing water. Washing the unit with water can cause an electrical shock.

Make sure that the unit is grounded when reparing the equipment in a wet or humid place to avoid electrical shocks.

Be sure to turn off the power switch when cleaning the equipment; the internal fan rotates at a high speed and may cause injury.

Do not tilt the unit when removing it. Water inside the unit can spill, wetting the floor.

Be sure to check that the refrigeration cycle section has cooled down sufficiently before conducting repair work. Working on the unit when the refrigerating cycle is hot can cause burns.

Use the brazing equipment in a well-ventilated place. Using the brazing equipment in an enclosed room can cause oxygen deficiency.

Be sure to use a dedicated power circuit for the equipment; follow appropriate technical standards for 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.

INTRODUCTION

SAFETY OVERVIEW

Read These Safety Precautions

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.

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.

If the cover is not mounted properly, the terminal connection section can cause an electrical shock, excessive heat generation, or fire.

Do not damage or modify the power cable.

Damaged or modified power cables can cause electrical shock or fire. Placing heavy items on the power cable and heating or pulling the power cable can damage the cable.

Do not introduce air into the refrigerant system. If air enters the refrigerant system, an excessively high pressure results, causing equipment damage and injury.

If the refrigerant leaks, be sure to locate the leak and repair it before charging the system with additional refrigerant. If the leak cannot be located and the repair work cannot be stopped, be sure to perform pump-down and close the service valve to prevent the refrigerant from leaking into the room. The refrigerant itself is harmless, but it can generate toxic gases when it contacts a heat source such as another appliance or an open flame.

When replacing the remote control battery, be sure to safely dispose of the battery.

Do not install the equipment in a place where there is a possibility of combustable gas leaks. If combustible gas leaks and remains near the unit, it may cause a fire.

Be sure to install the packing and seal on the installation frame correctly. If the packing and seal are not properly installed, water can spill out, wetting furniture and the floor.

Replace power cables and lead wires if they are scratched or deteriorated. Damaged cable and wires can cause electrical shock, excessive heat generation, or fire.

Check to see if the parts are mounted correctly, that the wires are connected correctly, and that connections at soldered or crimped terminals are secure. Improper installation and connections can cause excessive heat generation, electrical shock, and fire.

If the installation platform or frame has deteriorated or corroded, replace it. Corroded platform or frames can cause the unit to fall, resulting in injury.

Check to make sure that the equipment is grounded. Repair it if it is not properly grounded. Improper grounding can cause an electrical shock.

Be sure to measure the installation resistance of the repair. Be sure that the resistance is 1 M ohm or higher. Faulty installation can cause an electric shock.

Be sure to check the drainage of the indoor unit after the repair. Faulty drainage can cause a water leak from indoor unit and could cause property damage.

Important Safety Related Installation Information

Indoor Clearances: If noncompliant may lead to temperature control complaints.

Wire Sizing: If noncompliant may lead to communication errors and inverter irregular operation.

Splices in Field Wiring: Splices between the wires that connect between the outdoor and indoor unit should be avoided.

Sealing Penetrations: If penetrations at back of unit are not sealed, unconditioned air may be drawn into the back of the indoor wall mount unit. Temperature control and capacity complaints may occur.

property damage.

Use only dry nitrogen with a pressure regulator for pressurizing unit. Do not use acetylene, oxygen or compressed air or mixtures containing them for pressure testing. Do not use mixtures of a hydrogen containing refrigerant and air above atmospheric pressure for pressure testing as they may become flammable and could result in an explosion. Refrigerant used as a trace gas should only be mixed with dry nitrogen for pressurizing units. Failure to follow these recommendations could result in death or serious injury or equipment or property damage.

3.1 Step - 3.1

SECTION A

Using a tank of nitrogen with attached regulator, charge the system with 150 PSIG of dry nitrogen. Use adapter AD-87

(field supplied) to connect to the service valve. Check for leaks at the flare fittings using soap bubbles or other detection methods. If a leak is detected, repair and recheck. If no leaks are detected, proceed to evacuate the system.

System Evacuation

3.2 Step - 3.2

Attach a manifold gauge, micron gauge, and vacuum pump to the suction line port using adapter AD-87 (field supplied).

(Illustration 5)

Evacuate the system to 350 microns.

Close the vacuum pump valve and check the micron gauge. If the gauge rises above 500 microns in 60 seconds, evacuation is incomplete or there is a leak in the system. If the gauge does not rise above 500 microns in 60 seconds, evacuation is complete.
