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 guard switch which stops the
pump if the pumphead track is opened. The 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.
