8 . OPERATING PROBLEMS

Before carrying out any repair or maintenance
CAUTION ! work, DISCONNECT THE PUMP FROM THE
ELECTRICITY SUPPLY.
To prevent an operating incident with respect to the parts under-
pressure, these should be decompressed in advance (ventiation of
anti-reflux device and draining of reservoir, if necessary with the
hand pump).
OPERATING
TROUBLE
8.1. THE PUMP FAILS TO START
8.2. THE PUMP DOES NOT
DELIVER OR THERE IS
INSUFFICIENT FLOW
8.3. CURRENT INPUT TOO
HIGH
8.4. DISCHARGE HEIGHT TOO
SMALL
8.5. INPUT POWER TOO HIGH
8.6. THE PUMP OPERATES IN
AN IRREGULAR MANNER
AND MAKES A LOT OF
NOISE
CAUSE
a) Lack of current :
b) Pump inlet obstructed :
c) Motor winding or conducting
wire in bad condition :
d) Non-return valve obstructed :
e) Winding temperature too high,
winding temperature probe
cut :
f) The degassing pipe of the pump
is obstructed :
a) Pump inlet or impeller
obstructed :
b) Incorrect rotation direction :
c) Internal components worn
(wheel, bearing) :
d) Non-return valve obstructed :
e) Excessive drop in water level in
reservoir :
f) The discharge valve is not open
completely :
g) Unacceptable air or gas
content in the pumped liquid :
a) Incorrect rotation direction :
b) Operating voltage too low :
