Page 21: Pressure Test And Evacuating System
Outdoor Unit Installation Pressure test and evacuating system WARNING • Do not mix any substance other than the specified refrigerant (R410A) into the refrigeration cycle. • If refrigerant gas leaks should occur, ventilate the room as soon and as much as possible. • R410A, as well as other refrigerants, should always be recovered and never be released directly into the environment. • Use a vacuum pump for R410A exclusively. Using the same vacuum pump for different refrigerants may damage the vacuum pump or the unit. • When piping work is complete, it is necessary to perform a pressure test Compound Pressure High-pressure... -
Page 22: Refilling Refrigerant
Refilling refrigerant Check the type of refrigerant to be used on the machine nameplate. Precautions when adding R410A Fill from the liquid pipe in liquid form. This is a mixed refrigerant, so adding it in gas form may cause the refrigerant composition to change, preventing normal operation. - Page 23 Wiring WARNING • Do not use tapped wires, extension cords, or starburst connections, as they may cause overheating, electrical shock, or fire. • Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc., from the terminal block.) Doing so may cause electric shock or fire. • Be sure to install a ground fault circuit interrupter. (One that can handle higher harmonics.) (This unit uses an inverter, which means that a ground fault circuit interrupter capable of handling harmonics must be used in order to prevent any malfunction of the ground fault circuit interrupter itself.) • Use an all-pole disconnection type circuit breaker with at least 1/8 inch (3mm) between the contact point gaps.
