Electric shock hazard.
Some components have capacitors charged to over 60VDC. When power
is switched off, they keep their charge for a time. Residual voltages
from the filter capacitors can cause electric shocks all the way back to
the mains plug. Wait 5 minutes after power-off before commencing any
work on the appliance.
Users are advised to observe the precautions presented below during
any maintenance operation on the pump and, more especially, any
operations requiring the disassembly of sub-assemblies.
