SAFETY SUMMARY < Sgnal Words > l Signal words are used to identify levels of hazard seriousness. Definitions for identifying hazard levels are provided below with their respective signal words. : DANGER indicates a hazardous situation which, if not avoided, DANGER will result in death or serious injury. : WARNING indicates a hazardous situation which, if not avoided, WARNING could result in death or serious injury.
Page 6 SAFETY SUMMARY DANGER l Do not perform the installation work, refrigerant piping work, drain pump, drain piping and electrical wiring connection without referring to our installation manual. If the instructions are not followed, it may result in a water leakage, electric shock or fire. l Use the specified non-flammable refrigerant (R410A) to the outdoor unit in the refrigerant cycle.
Page 7 SAFETY SUMMARY WARNING l Do not use any sprays such as an insecticide, lacquer, hair spray or other flammable gases within approxmately one (1) meter from the system. l If the circuit breaker or fuse is often activated, stop the system and contact your service contractor. l Check that the ground wire is securely connected.
Page 8 SAFETY SUMMARY NOTICE l Do not install the indoor unit, outdoor unit, remote control switch and cable within approximately 3 meters from strong electromagnetic wave radiators such as medical equipments. l Supply electrical power to the system to energize the crankcase heater for 12 hours before startup after a long shutdown.

Deﬁnitions for identifying hazard levels are provided below with their respective signal words. : DANGER indicates a hazardous situation which, if not avoided, DANGER will result in death or serious injury.
Page 183 WALL TYPE DANGER l Do not perform the installation work, refrigerant piping work, drain pump, drain piping and electrical wiring connection without referring to our installation manual. If the instructions are not followed, it may result in a water leakage, electric shock or a ﬁre. l Use the speciﬁed non-ﬂammable refrigerant (R410A) to the outdoor unit in the refrigerant cycle.
Page 184 WALL TYPE WARNING l The installation work shall be performed by the specialist installer. If it is not completed, it may cause a water leakage, an electric shock, a ﬁre or falling down the unit. l Perform the electrical work according to Installation Manual and all the relevant regulation and standards. If the instructions are not followed, an electrical shock and ﬁre may occur due to insufﬁcient capacity and inadequate performance.
Page 185 WALL TYPE l When the indoor unit is operated with heating appliances, ventilate a room sufﬁciently. If not, it may cause suffocation. l Turn OFF the main power source immediately if the protection device is frequently activated or the main power source switch does not work.
Page 186 WALL TYPE CAUTION l Do not step or put any material on the product. l Do not put any foreign material on the unit or inside the unit. l Do not turn OFF the main power source of the indoor unit during the season of heating and cooling. The water can not be discharged forcedly so that overﬂows from the drain pan.
Page 187: System Description
WALL TYPE System Description A maximum total capacity of 130% and a minimum total capacity of 50% can be chosen by combination of the indoor units (Table 2.1). The heat pump air conditioner is designed to offer cooling, heating, dry and fan operations. These operation modes are controlled by the remote control switch (optional).
Page 188: Before Operation
WALL TYPE Before Operation Supply electrical power to the system for approximately 12 hours before start-up after long shutdown. Do not start the system immediately after power supply, it may cause a compressor failure, because the compressor is not heated well. Make sure that the outdoor unit is not covered with snow or ice. If covered, remove it by using hot water (approximately 50 If the water temperature is higher than 50 C, it will cause damage to plastic parts.
