NOTE: Check the pressure on the pressure gauge while
the sand filter is operating. Generally, when the pressure
of the recommended sand filter pump is less than 0.2 bar
(3 psi) (green area), it runs normally. Note: Maintenance
can only be performed after the sand filtration pump has
been disconnected. Otherwise, serious personal injury or
even death may result. Note: While the sand filtration
pump is running, record the reading on the pressure
gauge. When the pressure gauge shows 0.2 bar (3 psi) or
higher, clean the sand bed or replace the sand. Use the
"backwash" and "rinse" functions. Note: depending on the specific application, we
recommend periodic flushing.
