Special installation instructions
n Position the end of the discharge line higher than the fluid level in the
storage tank to avoid overstraining.
n Position the outlet of the discharge line higher than the fluid level in
the storage tank to avoid overstraining.
n Install an adjustable back pressure valve in the discharge line and
install a shut-off valve in the suction line, which has to be closed when
the pump is at a standstill (preferably a solenoid valve).
n If the system is primed from lines with fluctuating pressure, use a
hopper with a float valve to ensure a regular discharge flow.
