Installation Guidelines

Requires pre-filling; install at system's lowest position to keep impeller immersed
Avoid dry running (automatic stop after 15 minutes)
Use recommended 38mm (1.5 inch) diameter piping
Can be installed vertically or horizontally
Outlet port should be upward when installed vertically
Maintain vertical pipe connections without elbows within 20cm
Not suitable for seawater or liquids with large grain impurities
