Page 6: Information About The Refrigerant
EWYT_B units are designed and built for cooling/heating buildings or industrial processes. The first commissioning on the final plant must be carried out by Daikin technicians, specifically trained for this purpose. Failure to follow this start-up procedure affects the warranty of the supply. - Page 7 • A remote switching (emergency type) for stopping the refrigerating system shall be provided outside the room (near the door). A similar acting switch shall be located at a suitable location inside the room. • All piping and ducting passing through floors, ceiling and walls of machinery room shall be sealed. •...
