01. Introduction
Read this manual carefully before installing and using
the product. Improper use of the product can cause
personal injury and damage to property and may void
the warranty. When ordering spare parts use page 15.
02. Use of Booster Set
Water is usually delivered by public supply systems
and the pressure is generally sufficient for the proper
operation of the user's water and sanitary equipment.
When this pressure is not sufficient, booster sets are
installed to increase water pressure and ensure an
acceptable minimum value at the furthest points.
Therefore, the water supply to a building, group of
buildings or to a system, in general, can be considered
satisfactory when all the user points can deliver the
required quantity of water.
03. Schematic Booster Set Connection
Method
Water is supplied by installing a water storage tank
between the users off take and booster set. (Fig.1)
04. Handling
When the booster unit is delivered, check that it has not
been damaged during shipping. Promptly inform our
nearest dealer, if necessary. Do not use the eyebolts,
expansion tanks, inlet and discharge manifolds etc., as
they are not designed to bear the weight of the booster
set. The product must be handled with care using
suitable hoisting equipment; accidents can damage
the product without being necessarily visible on the
outside; hoisting non-packed products by securely
putting them into a sling from the main chassis. Please,
put the unit on to the floor, gently.
05. Applications
The booster sets are suitable for water handling
systems in the civil, industrial and agricultural sectors,
for pressure boosting water supply for small houses,
buildings, factories, industrial plants, holiday villages
and water treatment plants.
They are not suitable for;
• Liquids containing abrasives
• Liquid with solid and fibrous substances - Flammable
and explosive liquids
06. Installation
For booster unit lifting and moving sling it safely. The
unit should not be exposed to the weather or freezing
temperatures. Make sure that there are no obstacles,
preventing normal flow of the cooling air moved by
the motor fan. The booster set must be put on to a
horizontal concrete base or equivalent structure by the
4 pieces of rubber supports, which are provided with
the unit. The bigger industrial models must be firmly
secured by means of appropriate bolts to a concrete
base.
07. Suction and Discharge Pipes
Use pipes suitable for the maximum booster set
working pressure. The suction pipe must be perfectly
sealed and of suitable size for the suction conditions
(suction pipe Ø ≥min. inlet manifold Ø of the booster
set or pump). When the liquid level is lower than the
booster set, a foot valve must be fitted at the end of the
suction pipe (see Fig.2) (Fig.3)
