INITIAL START-UP
FOREWORD
- Check that the quantity of fluid in the suction tank is
greater than the amount you wish to transfer.
- Make sure that the residual capacity of the delivery tank
is greater than the quantity you wish to transfer.
- Make sure that the piping and line accessories are in
good condition.
WARNING :
TOXIC FLUID OR FUMES HAZARD
- Never start or stop the pump by connecting or cutting
out the power supply.
- Prolonged contact with some fluids can damage the
skin. The use of goggles and gloves is recommended.
NOTICE
Do not run the pump dry for more than 20 minutes.
This can cause serious damage to its components.
Fluid leaks can damage objects and injure persons.
NOTICE
Extreme operating conditions with duty cycles long-
er than 20 minutes can cause the motor temperature
to rise thus damaging the motor. For each duty cycle
of 20 minutes, allow for a rest phase of 20 minutes
with motor switched off.
NOTE
During the priming phase, the pump must discharge
all the air that is initially present from the delivery
line. Therefore it is necessary to keep the outlet open
to permit the evacuation of the air.
NOTICE
If an automatic type dispensing nozzle is
installed on the end of the delivery line, the
evacuation of the air will be difficult because
of the automatic stopping device that keeps
the valve closed. It is recommended that the
automatic nozzle be temporarily removed during
initial start-up.
IF THE PUMP
DOES NOT PRIME
Depending on the system characteristics, the priming
phase can last from several seconds to a few minutes. If
this phase is prolonged, stop the pump and verify:
- that the pump is not running completely dry (fill with
fluid f om the delivery line);
- that the suction pipe guarantees against air infilt ation;
- that the suction fil er is not clogged;
- that the suction height is not higher than 2 mt. (6.5 ft)
- that all air has been released from the delivery pipe.
AT THE END OF
THE INITIAL
START-UP
When priming has occurred, verify that the pump is
operating within the anticipated range, in particular:
- that under conditions of maximum back pressure, the
power absorption of the motor stays within the values
shown on the identific tion plate;
- that the suction pressure is not greater than 0.5 bar (7
psi);
- that the delivery back pressure does not exceed the
maximum back pressure for the pump.
