- Page 5 ● This system should be installed by personnel certified by HITACHI. Personnel must be qualified according to local, state and national building and safety codes and regulations. Incorrect installation could cause leaks, electric shock, fire or explosion. In areas where "Seismic Performance" requirements are specified, the appropriate measures should be taken during installation to guard against possible damage or injury that might occur in an earthquake if the unit is not installed correctly, injuries may occur due to a falling unit.
- Page 6 This unit is the pressurized system. Never loosen threaded joints while the system is under pressure and never open pressurized system parts. ● HITACHI will not assume any liability for injuries or damage caused by not following steps outlined or described in this manual. Unauthorized modifications to HITACHI products are prohibited as they… ◦...
- Page 7 ▫ Damp or uneven areas: Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the unit to prevent water damage and abnormal vibration. ▫ An area with high winds: Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle. ▫ A snowy area: Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents.
- Page 8 As originally manufactured, this unit contains refrigerant installed by HITACHI. HITACHI uses only refrigerants that have been approved for use in the unit’s intended home country or market. HITACHI distributors similarly are only authorized to provide refrigerants that have been approved for use in the countries or markets they serve.
- Page 9 ● Clamp electrical wires securely with a cable band after all wiring is connected to the terminal block. In addition, run wires securely through the wiring access channel. ● When installing the power lines, do not apply tension to the cables. Secure the suspended cables at regular intervals, but not too tightly.
- Page 10 ● Proper handling of this unit requires two-people. Safe handling and installing the indoor unit requires the strength of two people. Mounting the unit alone may cause injury due to fall of the unit. Although the unit may be girded with steel banding, do not use it for transportation. Avoid contact with finned surfaces of the heat exchanger as sharp edges can cause severe injury to hands and fingers. Use appropriate work gloves for the job. NOTICE ● Check to ensure that the condensate hose discharges moisture properly. If connected incorrectly, it can result in leakage and damage to furniture. ● Make sure to use the factory-supplied condensate hose and hose clamp. Other makes can cause moisture leakage.
- Page 11 Operation WARNING ● Do not insert fingers or objects into an air inlet/outlet. Injury can result from rotating fan blades or energized electrical components. ● Do not touch the wired controller with wet hands. It can result in a malfunction of the wired controller or an electrical shock. ● Hair spray, insecticides, lacquers, and other pressurized substances should not be used within 3.3ft (1m) of any air conditioning unit. It can react with energized electrical components and cause fire. ● Do not install the indoor unit anywhere discharge airflow can pass directly toward nearby heating appliances (space heaters). It may interfere with the combustion process in these units. ● When the indoor unit is operated in an area with heat sources, ventilate a room sufficiently. Any leaked refrigerant gases that happen to come into contact with any heat source can become toxic on contact which can cause asphyxiation in the immediate area.
- Page 12 Other WARNING ● Turn OFF all power at the main power source before performing maintenance work. Failure to do so can result in damage to internal components with severe or fatal electrical shock. ● Insulate all electrical components and connections from exposure to moisture. Failure to do so can result in an electrical short circuit and fire. ● Do not tamper with or attempt to "repair" electrical wiring or connections. Call your installer or electrical contractor. Serious or fatal injury can occur. ● Perform all maintenance work on a firm and stable foundation to minimize the risk of injury. ● Do not attempt to "clean" indoor unit components with liquid or powdered cleaning agents during maintenance. Electric shock, sparks, flame, and serious or fatal injury can occur. ● Inside piping is charged with refrigerant and highly pressurized. ● Do not spray deodorant inside the indoor unit. The copper pipe will corrode and cause gas leakage. ● Hold the air filter and the air inlet grille firmly when attaching or removing it. Carelessness can result in accident or injury. ● Do not operate the unit without the air filter set in place. If the air filter is not installed, dust may accumulate and breakdown may result.
- Page 13 Before Operation NOTICE Apply power to the outdoor unit(s) at least 12 hours prior to operation of the system for preheating of the compressor oil. Make sure that the outdoor unit is not covered with snow or ice. If it is covered with snow or ice, remove it by using hot water approximately 50 If the water temperature is higher than 50 C, it will cause damage to plastic parts.

- Page 27 Maintenance WARNING ● Turn OFF the power source before the maintenance work. If the power source is not turned OFF, the result may be an electric shock or fire. ● Perform the maintenance work with a stable foothold or foundation. This may prevent falling or injury. ● When cleaning, do not allow water inside the air conditioner. Water on electrical equipment may cause electric shock. ● Do not wash the interior of the indoor unit yourself. Use of commercially available cleaning agents may cause cracking of resin parts, deterioration of internal parts, and clogging of drainage channels, causing water leakage and electric shock. ● Do not spray deodorant inside the indoor unit. The copper pipe will corrode and cause gas leakage. ● Hold the air filter and the air inlet grille securely by hand when attaching or removing it. If not, it may cause the product to fall, resulting in an injury. 7.1 Cleaning Air Filter Clean the air filter when the filter sign is turned ON.
