  • Page 30 2. Duct Construction. (1) Series ART side flow units are equipped with horizontal supply and return air openings. Duct connection to the unit should be made with duct flanges and secured directly to the air openings with flexible duct connectors to avoid normal noise transmission. (2) For vertical air supply, a field supply plenum should be used.
  • Page 31 3. Lifting Method. When the unit is to be lifted and moved, attach ropes to the hoisting hangers (4 pieces) provided on the top corners of the unit. When the unit is lifted, its center of gravity tends to shift the unit to one side.

  • Page 33 7. Special Precautions When Dealing With Refrigerant R407C Unit (1) What Is New Refrigerant R407C? R407C is a zeotropic refrigerant mixture which has Zero Ozone Depletion Potential (ODP = 0) and thus, conforms to the Montreal Protocol regulation. It requires Polyol-ester (POE) oil for its compressor’s lubricant.
  • Page 34 c) Ensure that the compressor is not exposed to open air for more than the recommended time specified by its manufacturer (typically less than 10 minutes). Remove the seal-plugs only when the compressor is about to be brazed. d) The system should be thoroughly vacuumed to 1.0 Pa (-700mmHg) or lower. This vacuuming level is more stringent than R22 system so as to ensure no incompressible gas and moisture in the system.
  • Page 35 8. Electric Wiring Construct The Earth Connection. All electrical work must be carried out by a suitable qualified electrical trades-person and in accordance with local supply authority requirements and associated regulators. The unit is to be wired directly from an electrical distribution board either by a circuit breaker (preferred) or HRC fuse.
