1. GENERAL
Read this documentation carefully before installation.
Keep this manual with care for further consultation even after the first installation.

2. INSTALLATION

The set must be fitted in a well ventilated place, protected from unfavourable weather conditions, and with an environment
temperature not less than 4°C (10°C if motor pumps are installed too), and not exceeding 40°C. Position the set in such a way that
any maintenance jobs can be carried out without difficulty.
Provide a raised and flat (levelled) support base suitable for supporting the unit and damping the vibrations: the manufacturer is not
liable for any damage caused by vibrations resulting from incorrect installation. If necessary, provide an anti-vibration mat between
the unit and the support base. The unit must not be installed on a slope or only partially in contact with the support base: if
necessary, provide additional supports along the entire length of the frame.
The means of fixing the unit to the support base (screws, bolts) must have suitable characteristics for fixing the unit. The unit must be
fixed avoiding stress and/or twisting on the frame.
The hydraulic connections must have autonomous supports in order not to burden the unit and not to transmit mechanical stress
after fixing.
Ensure that the system pipes are independently supported and do not weigh down on the set manifolds so as to avoid deformation
or breaking of any of its components.
It is advisable to insert vibration-damping couplings when connecting the suction and delivery pipes to the system, especially when installing
Diesel motor pumps.
Ensure that the characteristics of the water supply source are such as always to guarantee the flow rate required in the expected
operating conditions.
Make the intake section following all the precautions necessary to keep load losses to a minimum and to avoid the formation of air pockets, for
example:
a) Position the set as close as possible to the water supply source.
b) Provide each pump with its own intake pipe (EN 12845 - UNI 10779).
c) Lay the suction pipes horizontally or sloping slightly upwards towards the set.
d) Avoid using elbows or couplings that cause sudden changes in direction. If necessary, use bends with a wide radius.
Avoid the "siphon" effect at intake: it risks unpriming the pumps!
The vertical distance between the pump intake and the minimum water level must not exceed 3.2 metres. (EN 12845 point 10.6.2.3 - UNI 10779)
2.1 OPERATIONS NECESSARY FOR STARTING THE DIESEL MOTOR PUMP
ALL THE DIESEL MOTOR PUMP SETS ARE DELIVERED DRY, WITHOUT DIESEL FUEL, MOTOR OIL AND COOLING FLUID!
THE SET MUST NOT BE STARTED UNTIL IT HAS BEEN FILLED WITH DIESEL FUEL, MOTOR OIL AND COOLING FLUID!
IF THE FIRST START-UP OF THE DIESEL MOTOR PUMP SET IS CARRIED OUT MORE THAN 6 MONTHS AFTER THE
INSPECTION DATE, SPECIAL MAINTENANCE MUST BE PERFORMED (AS SPECIFIED IN THE MANUAL OF THE DIESEL
MOTOR IF SUPPLIED WITH THE MOTOR PUMP) BEFORE STARTING THE SET FOR THE FIRST TIME, SO AS TO ENSURE
THAT THERE IS NO DAMAGE CAUSED BY THE LONG PERIOD OF INACTIVITY.
Fill the tank of the Diesel motor pump with diesel fuel up to the maximum level to ensure 3-4-6 hours of autonomy depending on the risk
classes of the system (EN 12845 point 10.9.6 - UNI 10779). DAB motor pump sets guarantee 6 hours of autonomy.
a) FILL THE MOTOR WITH LUBRICATING OIL, as indicated in the table below.
(check the level of the motor lubricating oil with the dipstick provided).
b) Fill the air suction filter with special oil according to the instructions supplied with the Diesel motor
