  • Page 3 IMPORTANT NOTICE ● HITACHI pursues a policy of continuing improvement in design and performance of products. The right is therefore reserved to vary specifications without notice. ● HITACHI cannot anticipate every possible circumstance that might involve a potential hazard. ● This heat pump air conditioner is designed for standard air conditioning only. Do not use this heat pump air conditioner for other purposes such as drying clothes, refrigerating foods or for any other cooling or heating process. ● Do not install the unit at the following places. It may cause a fire, deformation, corrosion or failure. * Places where oil (including machinery oil) may be present in quantities. * Places where a lot of sulfide gas drifts, such as hot springs. * Places where inflammable gas may be generated or flow. * Places where strong salty wind blows, such as coast regions. * Places with an atmosphere of acidity or alkalinity. ● Do not install the unit in the place where silicon gas drifts. If the silicon gas attaches to the surface of the heat exchanger, the fin surface repels water. As a result, drain water splashes outside of the drain pan and splashed water runs inside of the electrical box. In the end, water leakage or electrical devices’ failure may occur. ● Pay attention to the following points when installing the unit in a hospital or other facilities where electromagnetic waves are generated from medical equipment. * Do not install the unit in the place where electromagnetic waves are directly radiated to the electrical box, controller cable or wired controller. * Install the unit at least 3 meters away from devices generating electromagnetic waves, such as a radio. ● Do not install the unit in the place where animals and plants catch the direct outlet air. It could adversely affect animals and plants. ● The installer and system specialist shall secure safety against the refrigerant leakage according to the local regulations or standards. The following standards may be applicable, if the local regulations are not available; International Organization for Standardization, ISO5149 or European Standard, EN378 or Japan Standard, KHKS0010. ● No part of this manual may be reproduced without written permission.
  • Page 4 CHECKING PRODUCT RECEIVED ● Upon receiving this product, inspect it for any shipping damage.

  • Page 6 SAFETY SUMMARY DANGER ● 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. ● Use the specified refrigerant (R410A or R32) to the outdoor unit in the refrigerant cycle. Do not charge the unit with material other than R410A or R32, such as hydrocarbon refrigerants (propane or etc.), oxygen, flammable gases (acetylene or etc.) or poisonous gases when installing, maintaining and moving the unit. These flammables are extremely dangerous and may cause an explosion, fire, and injury. ● Do not pour water into the indoor or outdoor unit. These products are equipped with electrical parts. If water is poured, it will cause a serious electrical shock. ● Do not open the service cover or access panel for the indoor or outdoor unit without turning OFF the main power supply. ● Do not touch or adjust safety devices inside the indoor unit or outdoor unit. If these devices are touched or readjusted, it may cause a serious accident. ● Refrigerant leakage can cause difficulty with breathing due to insufficient air. Turn OFF the main switch, extinguish any naked flames and contact your service contractor, if refrigerant leakage occurs. ● Make sure that a refrigerant leak test has been performed. Refrigerant (Fluorocarbon or Difluoromethane) for this unit is non-toxic, and odorless. If the refrigerant should somehow escape and come into contact with flame, toxic gas will form. This gas is heavier than air and will settle near floor areas and spread where it can cause suffocation to those nearby. In addition, difluoromethane is flammable and can cause fire. ● The installer and system specialist shall secure safety against refrigerant leakage according to the local regulations or standards. ● Use an ELB (Earth Leakage Breaker). In the event of fault, there is danger of an electric shock or fire if it is not used. ● Do not install the outdoor unit where there is high level of oil mist, flammable gases, salty air or harmful gases such as sulfur. ● For installation, firmly connect the refrigerant pipe before the compressor starts operating. For maintenance, relocation and disposal, remove the refrigerant pipe after the compressor stops.
  • Page 7 SAFETY SUMMARY WARNING ● Do not use any sprays such as an insecticide, lacquer or hair spray, or other flammable gases within approximately one (1) meter from the system. ● If the circuit breaker or fuse is often activated, stop the system and contact your service contractor. ● Check that the ground wire is securely connected. If the unit is not correctly grounded, it will lead to electric shock. Do not connect the ground wiring to a gas piping, water piping, lighting conductor or ground wiring for telephone. ● Connect a fuse of specified capacity. ● Before performing any brazing work, check to ensure that there is no flammable material around. When handling the refrigerant, be sure to wear leather gloves to prevent cold injuries. ● Protect the wires, electrical parts, etc. from rats or other small animals. If not, rats may gnaw at unprotected parts, which may lead to a fire. ● Fix the cables securely. External forces on the terminals could lead to a fire. ● Provide a sufficiently strong foundation. If not, the unit may fall down and it may lead to injuries. ● Do not install the unit in a place where oil, vapor, organic solvent and corrosive gas (ammonia, sulfur compound and acid) may be present in quantities. It may cause refrigerant leakage due to corrosion, electrical shock, deteriorated performance and breakage. ● Perform the electrical work according to Installation Manual and all the relevant regulations and standards. If the instructions are not followed, an electrical shock and fire may occur due to insufficient capacity and inadequate performance. ● Use specified cables between units and choose the cables correctly. If not, an electrical shock or fire may occur. ● Ensure that the wiring terminals are tightened securely with the specified torques. If not, a fire or an electrical shock at the terminal connection part may occur. CAUTION ● Do not step on the product nor put any material on it.
  • Page 8 SAFETY SUMMARY NOTICE ● Do not install the indoor unit, outdoor unit, wired controller and cables within approximately 3 meters from strong electromagnetic wave radiators, such as medical equipment. ● Supply electrical power to the system to energize the crankcase heater for 12 hours before startup after a long shutdown. ● Make sure that the outdoor unit is not covered with snow or ice, before operation. ● The packaged air conditioner may not be operated normally under the following cases. * In case that electrical power for the packaged air conditioner is supplied from the same power transformer as the device with high electricity consumption*. * In case that the power source wires for the device* and for the packaged air conditioner are located close to each other. Device*: (Ex) Lift, container crane, rectifier for electric railway, inverter power device, arc furnace, electric furnace, large-sized induction motor and large-sized switch. Regarding the cases mentioned above, surge voltage may be inducted in the power supply wiring for the packaged air conditioner due to a rapid change in power consumption of the device and an activation of switch. Therefore, check the field regulations and standards before performing electrical work in order to protect the power supply for the packaged air conditioner. NOTE ● It is recommended that the room be ventilated every 3 to 4 hours. ● The heating capacity of the heat pump unit decreases according to the outdoor air temperature. Therefore, it is recommended that auxiliary heating equipment be used in the field when the units is installed in a low temperature region. TCI-20007-rev.1...
