entail the risk of getting cut.
Take necessary cautions to avoid injuries and
use protective equipment (wear protective
gloves).
WARNING! Risk of personal injury!
Do not stand or put members under the sus-
pended parts during handling and installation.
Use protective clothing to prevent accidents
(wear helmet and safety shoes).
WARNING! Risk of impact!
Be careful of prominent parts and parts at head
level. Use protective clothing to prevent acci-
dents.
DANGER! Risk of fall!
Prohibit access to wells or tanks, where pumps
are installed. Wells must be covered.
WARNING! Risk of irritation!
During handling, avoid spillage of battery acid
solution which could cause irritations or mate-
rial damage. Use special protections to avoid
contact.

necessary measures to prevent pollution of soil,
water, etc.
4 Intended use
The pressure boosting systems for fire extinguish-
ing purposes are designed for professional use.
They are used when an increase of pressure or a
maintaining under pressure of the fire network is
necessary.
The system must be installed in a special room
which is protected from frost and rain, fireproof
and ventilated enough, with necessary spaces
around pumps for movements and regular main-
tenance. The room must be in accordance with the
EN 12845 standards. Airflow for ventilation and
for cooling of engines, more specifically diesel
engine -if present- has to be sufficient.
