  • Page 3: General Information

    1. General Information 1.1 Safety • This manual should always be accessible and close to this air condition equipment. • There are two types of indications, " WARNING" and " CAUTION". The indication preventing from death or heavy injury is listed as " WARNING".
  • Page 4 CAUTION • Grounding wire should be connected with the grounding bar. The grounding wire can not be connected to the gas pipe, water pipe, lightening rod or the telephone grounding wire. Improper grounding may cause electric shock. • Units installed on roof should have appropriate access and handrail. •...

  • Page 203 Product introduction • Water Cooled VRF is a water-air heat pump air condition equipment which can deliver cooling and heating by taking water as its heat source. Water acts as the heat-extraction source when heating, while heat-absorption source when cooling. Thus there is no risk of frost formation on condenser’s surface. •...

  • Page 205 Water system Cooling water system guarantees Water Cooled VRF reliable operation. Water volume and water temperature should reach the design index (see the technical parameter) during the designing of VRF water system in order to not cause cooling volume dropping or tripping protection because of inadequate water or lack water or water temperature too high.
  • Page 206 ③ Water treatment and control When the Circulating cooling water runs for a long time, it will produce algae, and salinity will rise, resulting in heat exchanger fouling, which will affect the heat transfer efficiency. It is better to process timely. Electronic water treatment meters should be included for scale resistance protection and water quality stabilization.

Water in heat exchanger should all be drained out during long shutdown in the winter to avoid icing; 4. The diameter of water pipe should be the same as the diameter of unit connection (1-1/4 inch) or larger. 5.
  • Page 209 ⑤ Auxiliary Thermal Source: In winter, circulating water temperature is maintained from 15 to 25°C. When in heating mode, the water temperature will drop down gradually, so there should have auxiliary heating source to maintain the water temperature in rating range. There are many types of auxiliary heating source, such as boiler, wasted heating source from factory, or civilian steam system.
