'22 • HM-T-415 When install the unit, be sure to check whether the selection of installation place, power source specifications, usage limitation (piping length, height differences between indoor and outdoor units, power source voltage and etc.) and installation spaces. SAFETY PRECAUTIONS l We recommend you to read this “SAFETY PRECAUTIONS”...
Page 4 '22 • HM-T-415 l Ensure that no air enters in the refrigerant circuit when the unit is installed and removed. If air enters in the refrigerant circuit, the pressure in the refrigerant circuit becomes too high, which can cause burst and personal injury.
Page 5 '22 • HM-T-415 l Do not install the unit where corrosive gas (such as sulfurous acid gas etc.) or combustible gas (such as thinner and petroleum gases) can accumulate or collect, or where volatile combustible substances are handled. Corrosive gas can cause corrosion of heat exchanger, breakage of plastic parts and etc. And combustible gas can cause fire. l Secure a space for installation, inspection and maintenance specified in the manual.
Page 6 '22 • HM-T-415 l Do not shut off the power source immediately after stopping the operation. Wait at least 5 minutes, otherwise there is a risk of water leakage or breakdown. l Do not control the system with main power switch. It can cause fire or water leakage.
