Min. static pressure at 82° C:
2-3 m (depending on model)
Min. static pressure at 95° C:
4-6 m (depending on model)
Operating temp. ("C"):
-15° C to +120° C 100° C
Airborne sound pressure
FLC 40-5 to FLC 50-8 maximum 43 dB (A)
FLC 50-10 to FLC 80-15 maximum 55 dB (A)
1.2.1 Characteristics of pumped fluid
Clean water, non-aggressive, non-explosive and
solid/fibre-free fluids.
Anti-freeze (water + glycol) up to 50%.
N.B.: no other liquid should be used unless
agreed in advance.
2. SAFETY
Please read these instructions carefully before
assembly and start-up.
In particular, make sure that the points concern-
ing the safety of the material for intermediate or
final users are observed.

2.2 SAFETY REQUIREMENTS
The outer surface of the pump may be
very hot.
When venting the air from the pump
(fig. 4), a small amount of hot water or steam
may leak.
The pumps must be electrically connect-
ed according to current law.
Disconnect the pump from the mains
power supply before moving the speed switch
or working on the terminal block.
3.

TRANSPORT AND STORAGE

Make sure the material has not suffered damage
during transport upon receipt.
If any damage is found, take action against the
carrier in good time.
ATTENTION
store it in a dry area and protect it from
impact and from the weather (humidity,
frost, etc.).
Move the pump with care so as not to alter the
shape and alignment of the hydraulic compo-
nents.
Never hang it from its power cable.
