pump need to be serviced?
The Apex pump has a mean time between failure (MTBF) of at least 2500hrs. It is recommended that a service be performed when this time has been reached. The Apex pump will automatically warn the user when this time has elapsed. (The message ‘Serv due’ will appear at power up). The Apex pump also stores the total amount of hours that it has been used, and displays this in the configuration mode. Items typically replaced during routine service can include pump diaphragm rubbers, bearings and motor.
