Note the changes of DVM PLUS III, IV by comparing to DVM PLUS II Cautions Correctpipingwork Wrongpipingwork The refrigerant piping should be the same level or lower than connecting position of piping to outdoor units. Piping work should be run with side direction for better uniform distribution of refrigerant and oil like next diagram. Outdoor joint kits should be installed in a horizontal direction, even it is a low pressure pipe. Horizontal length = over 100mm Minimum 100mm When the piping length between outdoor and branch joints is 2m or more, a vertical trap has to be installed like right diagram. 200~300mm Less than 1m 2m or over 2m or over 26_ installing the unit The examples of the refrigerant pipe installation HeatPumpmodel ExampleofpipinglayoutsforDVMPLUSIV ENGLISH Using Y- joint Using Header joint Do not use Y-joint between Header joint and indoor units.
