The flow rates must fall between the minimum flow and pressure and maximum values. Flow rates below the minimum values shown will result in laminar flow that will drop reduce efficiency, cause erratic operation of the electronic expansion valve and could cause low temperature cut-out.

    Maintenance ESIE07-04 System Maintenance General To ensure proper operation at peak capacity and to avoid damage to package components, a program of periodic inspections should be set up and followed. The following items are intended as a guide and are to be used during inspection and must be combined with sound coming from compressor and electrical practices to ensure troublefree performance.
  • Page 331 ESIE07-04 Maintenance Evaporator The units are supplied with new optimised counter-flow evaporator, single refrigerant pass. It is direct expansion (2 evaporators for units with 4 compressors) with refrigerant inside the tubes and water outside (shell side) with carbon steel tube sheets, with straight copper tubes that are spirally wound internally for higher efficiencies, expanded on the tube plates.

    No maintenance is ordinary required except the occasional removal of dirt and debris from the outside surface of the fins. Daikin recommends the use of foaming coil cleaners available at air conditioning supply outlets. Use caution when selecting such cleaners as some may contain potentially harmful chemical.
