Page 4: Safety Precautions
'10 • HM-T-149 When install the unit, be sure to check whether the selection of installation place, power supply specifications, usage limitation (piping length, height differences between indoor and outdoor units, power supply voltage and etc.) and installation spaces SAFETY PRECAUTIONS l We recommend you to read this “SAFETY PRECAUTIONS” carefully before the installation work in order to gain full advantage of the functions of the unit and to avoid malfunction due to mishandling. l The precautions described below are divided into and . The matters with possibilities leading to serious consequences such as death or serious personal injury due to erroneous handling are listed in the and the matters with possibilities leading to personal injury or damage of the unit due to erroneous handling including probability leading to serious consequences in some cases are listed in . These are very important precautions for safety. Be sure to observe all of them without fail. l Be sure to confirm no anomaly on the equipment by commissioning after completed installation and explain the operating methods as well as the maintenance methods of this equipment to the user according to the owner's manual. l Keep the installation manual together with owner’s manual at a place where any user can read at any time. Moreover if necessary, ask to hand them to a new user WARNING l Installation must be carried out by the qualified installer. If you install the system by yourself, it may cause serious trouble such as water leaks, electric shocks, fire and personal injury , as a result of a system malfunction. l Install the system in full accordance with the instruction manual. Incorrect installation may cause bursts, personal injury, water leaks, electric shocks and fire. l Use the original accessories and the specified components for installation. If parts other than those prescribed by us are used, It may cause water leaks, electric shocks, fire and personal injury. l When installing in small rooms, take prevention measures not to exceed the density limit of refrigerant inthe event of leakage. Consult the expert about prevention measures. If the density of refrigerant exceeds the limit in the event of leakage, lack of oxygen can occur, which can cause serious accidents. l Ventilate the working area well in the event of refrigerant leakage during installation.
Page 5 '10 • HM-T-149 l Do not open the service valves for liquid line and gas line until completed refrigerant piping work, air tightness test and evacuation. If the compressor is operated in state of opening service valves before completed connection of refrigerant piping work, air can be sucked into refrigerant circuit, which can cause bust or personal injury due to anomalously high pressure in the refrigerant. l Do not put the drainage pipe directly into drainage channels where poisonous gases such as sulphide gas can occur. Poisonous gases will flow into the room through drainage pipe and seriously affect the user’s health and safety l Only use prescribed optional parts. The installation must be carried out by the qualified installer. If you install the system by yourself, it can cause serious trouble such as water leaks, electric shocks, fire. l Do not run the unit with removed panels or protections. Touching rotating equipments, hot surfaces or high voltage parts can cause personal injury due to entrapment, burn or electric shocks. l Be sure to fix up the service panels. Incorrect fixing can cause electric shocks or fire due to intrusion of dust or water. l Do not perform any repairs or modifications by yourself. Consult the dealer if the unit requires repair. If you repair or modify the unit, it can cause water leaks, electric shocks or fire. l Do not perform any change of protective device itself or its setup condition. The forced operation by short-circuiting protective device of pressure switch and temperature controller or the use of non specified component can cause fire or burst. l Be sure to switch off the power supply in the event of installation, inspection or servicing. If the power supply is not shut off, there is a risk of electric shocks, unit failure or personal injury due to the unexpected start of fan. l Consult the dealer or an expert regarding removal of the unit. Incorrect installation can cause water leaks, electric shocks or fire. l Stop the compressor before disconnecting refrigerant pipes in case of pump down operation. If disconnecting refrigerant pipes in state of opening service valves before compressor stopping, air can be sucked, which can cause burst or personal injury due to anomalously high pressure in the refrigerant circuit. CAUTION l Carry out the electrical work for ground lead with care.
Page 6 '10 • HM-T-149 ・Locations with heavy snow. (If installed, be sure to provide base flame and snow hood mentioned in the manual) ・Locations where the unit is exposed to chimney smoke. ・Locations at high altitude. (more than 1000m high) ・Locations with ammonic atmospheres. ・Locations where heat radiation from other heat source can affect the unit. ・Locations without good air circulation. ・Locations with any obstacles which can prevent inlet and outlet air of the unit. ・Locations where short circuit of air can occur. (in case of multiple units installation) ・Locations where strong air blows against the air outlet of outdoor unit. It can cause remarkable decrease in performance, corrosion and damage of components, malfunction and fire. l Do not install the outdoor unit in the locations listed below. ・Locations where discharged hot air or operating sound of the outdoor unit can bother neighborhood. ・Locations where outlet air of the outdoor unit blows directly to plants. ・Locations where vibration can be amplified and transmitted due to insufficient strength of structure. ・Locations where vibration and operation sound generated by the outdoor unit can affect seriously. (on the wall or at the place near bed room) ・Locations where an equipment affected by high harmonics is placed. (TV set or radio receiver is placed within 5m) ・Locations where drainage cannot run off safely. It can affect surrounding environment and cause a claim. l Do not install the remote controller at the direct sunlight. It can cause malfunction or deformation of the remote controller. l Do not use the unit for special purposes such as storing foods, cooling precision instruments and preservation of animals, plants or art. It can cause the damage of the items. l Take care when carrying the unit by hand. If the unit weights more than 20kg, it must be carried by two or more persons. Do not carry by the plastic straps, always use the carry handle when carrying the unit by hand. Use gloves to minimize the risk of cuts by the aluminum fins. l Dispose of any packing materials correctly. Any remaining packing materials can cause personal injury as it contains nails and wood. And to avoid danger of suffocation, be sure to keep the plastic wrapper away from children and to dispose after tear it up. l Pay attention not to damage the drain pan by weld spatter when welding work is done near the indoor unit. If weld spatter entered into the indoor unit during welding work, it can cause pin-hole in drain pan and result in water leakage. To prevent such damage, keep the indoor unit in its packing or cover it. l Be sure to insulate the refrigerant pipes so as not to condense the ambient air moisture on them. Insufficient insulation can cause condensation, which can lead to moisture damage on the ceiling, floor, furniture and any other valuables. l Be sure to perform air tightness test by pressurizing with nitrogen gas after completed refrigerant piping work. If the density of refrigerant exceeds the limit in the event of refrigerant leakage in the small room, lack of oxygen can occur, which can cause serious accidents.

Page 274 '10 • HM-T-149A Service Operation control function by the indoor unit controller Heating curve offset It is possible to offset the heating curve chosen in the menu above in order to obtain higher target supply water temperature. The offset for heating system 1 can be set using the knob on the controller. The set value can be seen in Menu 2.1.1. The figure below shows the case that heating curve 9 is chosen with heating curve offset +2.
