– 4 –• The hot water module has been designed to be fitted at floor level.Installation• Install the hot water module securely in a location where the base cansustain the weight adequately. If the strength is not enough, the unitmay fall down resulting in injury.• Follow the instructions in the Installation Manual to install the hotwater module. Failure to follow these instructions may cause theproduct to fall down or topple over or give rise to noise, vibration,water leakage or other trouble.• Carry out the specified installation work to guard against thepossibility of earthquake. If the hot water module is not installedappropriately, a unit may topple over or fall down, causing anaccident.• If refrigerant gas has leaked during the installation work, ventilate theroom immediately. If the leaked refrigerant gas comes in contact withfire, noxious gas may generate.• Use forklift to carry in the hot water module units and use winch orhoist at installation of them.• Helmet must be worn to protect your head from falling objects.Especially, when you work under an inspection opening, helmet mustbe worn to protect your head from falling objects from the opening.• The unit can be accessed from the service panel.Refrigerant piping• Install the refrigerant pipe securely during the installation work beforeoperating the hot water module. If the compressor is operated withthe valve open and without refrigerant pipe, the compressor sucks airand the refrigeration cycles is over pressurized, which may cause ainjury.• Tighten the flare nut with a torque wrench in the specified manner.Excessive tighten of the flare nut may cause a crack in the flare nutafter a long period, which may result in refrigerant leakage.• After the installation work, confirm that refrigerant gas does not leak.If refrigerant gas leaks into the room and flows near a fire source,such as a cooking range, noxious gas may be generated.• When the hot water module has been installed or relocated, follow theinstructions in the Installation Manual and purge the air completely sothat no gases other than the refrigerant will be mixed in therefrigerating cycle. Failure to purge the air completely may cause thehot water module to malfunction.• Nitrogen gas must be used for the airtight test.• The charge hose must be connected in such a way that it is not slack.Water piping• Do not install water pipes in a location that is susceptible to freezing.Electrical wiring• Only a qualified installer (*1) or qualified service person (*1) isallowed to carry out the electrical work of the hot water module. Underno circumstances must this work be done by an unqualified individualsince failure to carry out the work properly may result in electricshocks and / or electrical leaks.• To connect the electrical wires, repair the electrical parts or undertakeother electrical jobs, wear gloves to provide protection for electriciansand from heat, insulating shoes and clothing to provide protectionfrom electric shocks.
