Page 46: Replacing The Fuse
Malfunctions and Maintenance Replacing the fuse Repairs and maintenance may only be performed by a specialist. Before working on the unit, switch off the power supply and secure it against being switched on again! Check for the absence of power! Danger Only use the supplied spare fuses or fuses of the same design with the following specifi cations: T2A / 250V . - Page 47 Useful notes/tips and tricks Instead of setting the flow rate for the system using a flow rate limiter, it is better to adjust the flow rate using the switch on the pump and by means of the “max. speed” setting on the controller (see. „6.2.6. - max. speed“ on page 30).
