4. 15 If there is a refrigerant leakage make sure that it does not exceed the concentration 9 TEST RUN limit 9 1 Test run using Outdoor unit If a refrigerant leakage exceeds the concentration limit it can lead to accidents such as oxygen starvation 9 2 Test run using Remote Controller Do not touch refrigerant that has leaked from the refrigerant pipe connections or other 10 CHECK LIST 15 area Touching the refrigerant directly can cause frostbite 11 ERROR CODES 15 If a refrigerant leakage occurs during operation immediately vacate the premises and thoroughly ventilate the area If the refrigerant comes in contact with a flame it produces a toxic gas 1 SAFETY PRECAUTIONS Be sure to read this Manual thoroughly before installation The warnings and precautions indicated in this Manual contain important information pertaining to your safety Be sure to observe them Hand this Manual together with the Operating Manual to the customer Request the customer to keep them on hand for future use such as for relocating or N WARNING To install a unit that uses the R410A refrigerant use dedicated tools and piping materials that have been manufactured specifically for RA10A use
5. En 7 Install an earth leakage breaker In addition install the earth leakage breaker so that the entire AC main power supply is cut off at the same time Otherwise electric shock or fire could result Always connect the earth ground cable Improper earthing grounding work can cause electric shocks Install the remote controller cables so as not to be direct touched with your hand Perform wiring work in accordance with standards so that the air conditioner can be operated safely and positively Connect the connection cable firmly to the terminal board Imperfect installation may cause a fire If the supply cable is damaged it must be replaced by the manufacturer its service agent or similarly qualified persons in order to avoid a hazard N CAUTION Earth Ground the unit Do not connect the earth ground cable to a gas pipe water pipe lightning rod or a telephone earth ground cable Improper earthing grounding may cause electric shock Do not connect power supply cables to the transmission or remote controller terminals as this will damage the product Never bundle the power supply cable and transmission cable remote control cable together Separate these cable by 50 mm or more Bundling these cables together will cause miss operation or breakdown When handling PCB static electricity charged in the body may cause malfunction of the PCB Follow the cautions below
6. Because the pressure of the R410A refrigerant is approximately 1 6 times higher than the R22 failure to use dedicated piping material or improper installation can cause rupture or injury repairing the unit Furthermore it can cause serious accidents such as water leakage electric shock or fire This mark indicates procedures which if improperly Z WARNING performed might lead to the death or serious injury of the user Tool name Contents of change Request your dealer or a professional installer to install the unit in accordance with this Manual An improperly installed unit can cause serious accidents such as water leakage electric shock or fire If the unit is installed in disregard of the instructions in the Installation Manual it will void the manufacturer s warranty Pressure is huge and cannot be measured with a conventional R22 gauge To prevent erroneous mixing of other refrigerants the diameter of each port has been changed It is recommended to use a gauge manifold with a high pressure display range 0 1 to 5 3 MPa and a low pressure display range 0 1 to 3 8 MPa Gauge manifold Do not turn ON the power until all work has been completed Turning ON the power before the work is completed can cause serious accidents such as electric shock or fire To increase pressure resistance the hose material and base Charging hose size were changed If refrigerant leaks while work i
