1 Notes on documentation EN 1 Notes on documentation 1.3 Symbols used These assembly instructions are aimed at tradespersons who are familiar with assembly and installation of the fan-and-filter unit, and at trained specialists who are familiar with operation of the fan-and-filter unit. Please observe the following safety instructions and other notes in this guide: Symbol for an instructed action: • The bullet point indicates that you should perform an action. Safety and other notes: 1.
2 Safety notes 2 Safety notes 3 Device description Please observe the following general safety notes when assembling and operating the unit: – Assembly, installation and servicing may only be performed by properly trained specialists. – Do not obstruct the air inlet and outlet of the fan-and-filter unit inside and outside the enclosure (see also section “4.2.2 Layout of the components in the enclosure”, page 7).
3 Device description EN 3.1.2 Control Rittal fan-and-filter units may be controlled more efficiently using a thermostat (Model No. SK 3110.000), digital temperature display (Model No. SK 3114.200), temperature-dependent speed control (Model No. SK 3120.200) and/or hygrostat (Model No. SK 3118.000).

5 Carrying out the electrical 5 Carrying out the electrical installation fan. Units SK 3238.xxx to SK 3239.xxx are released by pulling out the clip (see Fig. 4) of the bayonet connection. 5.1 Installing the power supply EN SK 3238.xxx SK 3239.xxx • Complete the electrical installation by following the wiring plans. Note: For technical data refer to the rating plate. • Remove the red cover from the electrical connection. Fig. 4: Release the bayonet connection Units SK 3240.xxx, SK 3241.xxx, SK 3243.
6 Commissioning EN 6 Commissioning • Once all the assembly and installation work is complete, switch on the power supply to the fan-and-filter unit. The fan-and-filter unit operates automatically, in other words, the fan will start up once the power has been switched on. 6.1 Properties – Four voltage variants are supported: – 24 V DC – 115 V, 1~ – 230 V, 1~ – 400/460 V, 3-phase 7 Changing the filter Fig. 6: Release the louvred grille • Insert the filter mat into the louvred grille as shown in Fig.
8 Inspection and maintenance 8 Inspection and maintenance Risk of electric shock! The unit is live. Switch off the power supply before opening, and take suitable precautions against it being accidentally switched back on. 8.1 General The built-in, maintenance-free fan is mounted on a friction bearing (SK 3237.xxx, SK 3238.xxx and SK 3239.xxx) or ball bearing (SK 3240.xxx, SK 3241.xxx, SK 3243.xxx to SK 3245.xxx), and is protected against humidity and dust, and equipped with a temperature monitor.
