Pumphead replacement
Always isolate the pump from the mains power supply before opening any
guard or track, or performing any positioning, removal or maintenance
operation.
Primary safety is provided by the tool-lockable pumphead track. Secondary
(backup) protection is provided in the form of an optional guard switch which
stops the pump if the pumphead track is opened. The optional guard switch on
cased pumps should never be used as primary protection. Always disconnect
the mains power supply to the pump before opening the pumphead guard.
