Peristaltic Pump Service Procedure
1.
Flush the feed pump and tubing with fresh water. The filtration system must be running
to perform this task. Change filtration mode to ON if required, and use the ACID PRIME
or LCHL PRIME function in the ASP TOOLS menu to flush water through the tubing.

Note: This procedure is never guaranteed to flush all chemicals from the
system, especially if the pump has not been performing well. Always wear
appropriate protective clothing and proceed with caution when handling
liquid chlorine and/or acid while servicing the dosing system.
2.
To prepare the system for servicing, turn OFF and disconnect the filtration pump. Relieve
the plumbing of any pressure or vacuum.
a) Change the FILTRATION MODE to OFF using the MODE button.
b) Disconnect the filtration pump power cord to prevent accidental start up.
