    Safety Precautions • Read these Safety Precautions carefully to ensure correct installation. • This manual classifies the precautions into WARNING and CAUTION. • Be sure to follow all the precautions bellow: they are all important for ensuring safety. WARNING: Failure to follow any of WARNING is likely to result in grave consequences such as death or serious injury. CAUTION: Failure to follow any of CAUTION may in some cases result in grave consequences. • The following safety symbols are used throughout this manual: Be sure to observe this instruction Be sure to establish an earth connection Never attempt • After completing installation, test the unit to check for installation errors. Give the user adequate instructions concerning the use and cleaning of the unit according to the Operation Manual. WARNING • Installation should be left to the dealer or another professional. Improper installation may cause water leakage, electrical shock, or fire. • Install the air conditioner according to the instructions given in this manual. Incomplete installation may cause water leakage, electrical shock, or fire. • Be sure to use the supplied or specified installation parts. Use of other parts may cause the unit to come lose, water leakage, electrical shock, or fire. • Install the air conditioner on a solid base that can support the unit’s weight. An inadequate base or incomplete installation may cause injury in the event the unit falls off the base. • Electrical work should be carried out in accordance with the installation manual and the national electrical wiring rules or code of practice. Insufficient capacity or incomplete electrical work may cause electrical shock or fire. • Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance. • For wiring, use a cable long enough to cover the entire distance with no connection. Do not use an extension cord. Do not put other loads on the power supply, use a dedicated power circuit. (Failure to do so may cause abnormal heat, electric shock or fire.) • Use the specified types of wires for electrical connections between the indoor and outdoor units. Firmly clamp the interconnecting wires so their receive no external stresses. Incomplete connections or clamping may cause terminal over- heating or fire. • After connecting interconnecting and supply wiring be sure to shape the cables so that they do not put undue force on the electrical covers or panels. Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, or fire. • If any refrigerant has leaked out during the installation work, ventilate the room. (The refrigerant produces a toxic gas if exposed to flames.) • After all installation is complete, check to make sure that no refrigerant is leaking out.

    Step 5 - Leak Test and Evacuation Leak Test Hazard of Explosion! Never use an open flame to detect gas leaks. Explosive conditions may occur. Use a leak test solution or other approved methods for leak testing. Failure to follow recommended safe leak test procedures could result In death or serious injury or equipment or 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 Step 5.1 Step 5.2 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, when 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. Step - 5.1 Step 5.3 Step 5.4A Using a tank of nitrogen with attached regulator, charge the system with 500 PSIG of dry nitrogen. Use adapter AD-87 (field supplied) to connect to the 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 Step 5.4B Step 5.5A Step - 5.2 Attach a manifold gauge, micron gauge, and vacuum pump to the suction line port using adapter AD-87 (field supplied).

    Section 9 - Seacoast Application • The outdoor unit should be installed at least 1/2 mile away from the salt water, including seacoasts and inland waterways. If the unit installed from 1/2 mile to 5 miles away from the salt water, including seacoasts and inland waterways, please follow the installation instruction below. • Install the outdoor unit in a place (such as near buildings etc.) where it can be protected from sea breeze which can damage the outdoor unit. Sea breeze Sea breeze • If you cannot avoid installing the outdoor unit by the seashore, construct a protection wall around it to block the sea breeze. • A protection wall should be constructed with a solid material such as Protection walls concrete to block the sea breeze and the height and the width of the wall should be 1.5 times larger than the size of the outdoor unit. Also, secure over 28 in (700mm) between the protection wall and the outdoor unit for exhausted air to ventilate. Sea breeze • Install the outdoor unit in a place where water can drain smoothly. • If you cannot find a place satisfying above conditions, please contact manufacturer. Make sure to clean the sea water and the dust on the outdoor unit heat exchanger. INSTALLATION PAGE 43...
