Step 2. Run the power cable to the vent hole (Fig. 4).
Step 3. Remove the front panel from the fan. Then remove the circuit board cover (Fig. 5).
Step 4. Mark and drill holes for mounting the fan, fasten the sealing gasket, and then install the fan (Fig. 6-8).
Step 5. Connect the fan to power mains according to the wiring diagram (Fig. 12-20).
