    The line connection must be made at the power terminals of terminal block X1 (PE-L1- L2-L3) or directly on the terminals of the circuit breaker (depending on the model). Figure 11: Terminal block X1 for DFLEX series without PLR.

  • Page 35: Control And Signalling Connections

    Figure 12: Terminal block X1 for DFLEX series with PLR. Control and signalling connections All equipment with a Fisair electric control panel has the remote signalling card SEF-013, which provides remote information about the equipment status. The SEF-013 consists of 3 relays (NC-NA) identified on the terminal block as Rx1, Rx2 and Rx3.

  • Page 37: Flow Adjustment

    User Manual DFLEX Series | 37 Flow adjustment Steps for adjusting the process air flow (if the differential pressure sensor is not available): 1) Measure the differential pressure with a pressure gauge on the differential pressure ports located on the side of the basic unit (module 4).

  • Page 38: Differential Pressure Sensor

    User Manual DFLEX Series | 38 IMPORTANT: The reactivation fan has been designed to overcome a certain pressure or load loss. If this pressure or load loss is low, the closing of the reactivation damper for adjusting the nominal flow rate could produce areas of excessive heating in the elements of the heater.

  • Page 45: Maintaining The Dessicant Rotor

    User Manual DFLEX Series | 45 11.1 Maintaining the dessicant rotor The desiccant rotor is the only component of the dehumidifier that needs special attention. The desiccant rotor fitted to these units does not require specific ongoing maintenance. The speed of rotation is very slow, and the bearings and desiccant material are designed for continuous operation.

  • Page 46: Maintenance Of Air Filters

    1) Turn off the dehumidifier and wait for it to cool down. 2) Extract the filters from the unit. 3) Wash the filters using neutral pH soap and water or replace them. 4) Only replace the filters when they are completely dry. Always use FISAIR filters or filters with equivalent properties.
