User Manual DFRA Series | 46 9.10 Differential pressure sensor: The differential pressure sensor is located on the dry air fan module. Before starting the equipment, the pipes connected to this sensor must be correctly configured. This arrangement depends on the pressure differential to be measured, either between the plenum and suction side of the fan (pressure difference for calculating volume flow), or between drive plenum and P.atm (Pa).

User Manual DFRA Series | 48 Commissioning. Once the equipment has been connected to the air ducts and mains power supply, as well as the thermal fluids and/or control elements, where appropriate, the equipment commissioning process should be done as follows: Firstly, identify the PLR (Programmable Logic Relay) on the control panel and/or wiring diagram.
Page 49
User Manual DFRA Series | 49 If the equipment has PLR, please refer to the MMCSA (DFRA Series Operating and Control Manual) to start the equipment. Otherwise, follow the instructions below: 1) Set switch I1. 2) Move the I2 switch to the selected position (manual or automatic) to start the dehumidifier.
Page 50
User Manual DFRA Series | 50 To operate the PLR, refer to the MMCSA (Operation and Control Manual Series DFRA) to start the equipment. 4) If it is the first time the equipment has been used: Check that the flow control dampers are at least 50% open.
User Manual DFRA Series | 51 General maintenance. The following service table is for guidance only, as the frequency will depend on the conditions of each installation. ACTION FREQUENCY According to the dehumidifier's Cleaning the filters instructions. Inspection of the wet air fan impeller (reactivation)
User Manual DFRA Series | 52 12. Maintaining the desiccant 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.
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.
User Manual DFRA Series | 54 14. Maintaining the rotor drive system 14.1 Drive belt replacement (disassembly and assembly) This section has the instructions for the drive belt replacement: 14.1.1 Disassembly 1. If the DFRA equipment is operating, it must be stopped. To do this, set selector I2 to zero (stop) and wait five minutes until the two fans stop completely.
