OPERATING AND MAINTENANCE MANUAL PART 2
THE USER SHOULD KEEP THIS DOCUMENT
1. INTRODUCTION
This instruction manual is split into two booklets: PART 1,
containing general information regarding our whole product
range; and PART 2, containing information specific to the
motor-driven pump you have purchased. The two publica-
tions are complementary to each other, so make sure you
have both.
Comply with the instructions contained in them to get the
most out of your motor-driven pump and assure its proper
operation. If you need further information, get in touch with
your nearest authorized dealer.
If information in the two parts contradict each other, take
PART 2 containing the product's specific information as
valid.
NO PART OF THESE ILLUSTRATIONS AND/OR TEXT MAY BE
REPRODUCED FOR ANY REASON.
The following symbols have been used in the compilation of
this instruction booklet:

Description
MOTOR-DRIVEN SURFACE PUMPS
MODEL / Type
LPS / Vertical in-line centrifugal
3.2. USE FOR WHICH PUMPS ARE DESIGNED
For handling of clean water, water and glycol solutions and
other liquids compatible with AISI 304 steel in general (do-
mestic, commercial and industrial circulation, heating, cool-
ing and air-conditioning systems; handling of hot sanitary
water, low-pressure liquids).
Use the motor-driven pump based on its technical specifica-
tions.
3.3. USE FOR WHICH PUMPS ARE NOT DESIGNED
Pumps cannot be used to handle dirty water, water contain-
ing acids and corrosive liquids in general, water with tem-
peratures higher than those mentioned in chap. 4, saltwater,
flammable liquids and hazardous liquids in general.
The motor-driven pumps must never be made to work with-
out liquid, and must always operate below the maximum
suction pressures (see chap. 4).
