Page 36: Drain Piping
Magnus Series Outdoor Unit 3 Drain Piping 3.1 Design Considerations Drain piping design should take account of the following considerations: ▪ Indoor unit condensate drain piping needs to be of sufficient diameter to carry the volume of condensate produced at the indoor units and installed at a slope sufficient to allow drainage. Discharge as close as possible to the indoor units is usually preferable. - Page 37 Magnus Series Outdoor Unit Figure 3-5.5: Drain piping air vents Vent ▪ Air conditioner drain piping should be installed separately from waste, rainwater and other drain piping and should not come into direct contact with the ground. ▪ Drain piping diameter should be not less than the indoor units’ drain piping connection. ▪...

Page 43: Installation In Areas Of High Salinity
Magnus Series Outdoor Unit 6 Installation in Areas of High Salinity 6.1 Caution Do not install outdoor units where they could be directly exposed to sea air. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient performance. Outdoor units installed in seaside locations should be placed such as to avoid direct exposure to the sea air and additional anticorrosion treatment options should be selected, otherwise the service life of the outdoor units will be seriously affected. -
