OPERATING AND MAINTENANCE MANUAL PART 2 THE USER SHOULD KEEP THIS DOCUMENT
INTRODUCTION
This instruction manual is split into two booklets: PART 1, con-taining
general information regarding our whole product range; and PART 2, containing
information specific to the motor-driven pump you have purchased. The two
publications are comple-mentary 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 AND USE OF MOTOR-DRIVEN PUMP
3.1. DESCRIPTION
Description: Model:
SUBMERSIBLE MOTOR-DRIVEN PUMPS OPTIMA/BEST RIGHT DW – DW VOX
3.2. USE FOR WHICH PUMPS ARE DESIGNED
The motor-driven pumps can be used for: — handling clear water (OPTIMA/BEST)
as well as dirty or sew-
age water (RIGHT-DW) with solids in suspension up to the diameter indicated in
chap. 4; — pumping water out of garages, cellars, basements, tanks,
reservoirs, fountains, rainwater drains; flood irrigation of vegetable patches
and gardens and oxygen-ating water. The DW series can also be used to drain
rainwa-ter drains, cesspits and septic tanks, and trenches etc..
WARNING!
ONLY USE RIGHT- AND DW-SERIES MOTOR-DRIVEN PUMPS FOR CONTINUOUS DUTY IF THEY
ARE FULLY SUBMERSED. DO NOT USE RIGHT – DW MOTOR-DRIVEN PUMPS WITH THE MOTOR
OUT OF WATER FOR MORE THAN 15 MINUTES.
Use the motor-driven pumps based on their technical speci-fications.
3.3. USE FOR WHICH PUMPS ARE NOT DESIGNED The pumps cannot be used to handle:
— water containing acids or bases, and corrosive liquids in gen-eral; — water
with a temperature over the temperature limit given in chap. 4. — seawater; —
flammable liquids and hazardous liquids in general; — cannot be used in
swimming pools (accordingto EN 60335-2-41); — pumps with a cable less than 10m
long cannot be used out- doors. (OPTIMA MS with 5 m cable is excluded from
outdoor usage)
The motor-driven pumps must never be made to work without liquid.

4.5. INFORMATION ON AIRBORNE NOISE
Given the type of use, the motor-driven pumps do not exceed an A-weighted
sound pressure emission level of 70 dB (A).
PREPARING FOR USE
WARNING!
USE A ROPE FASTENED AROUND THE HANDLE TO LIFT OR LOWER THE MOTOR-DRIVEN PUMP:
NEVER PULL THE POWER CABLE AND/OR FLOAT CABLE AND SWITCH (FIG. 12).
5.1. INSTALLATION (FIG.1-5)
To install the pumps, proceed as directed in PART 1, chapter 7.2 and in the
following point: a) It is best to use rigid pipes (metal pipes on DW series)
for permanent installations and flexible pipes for temporary installations,
with sizes as given in chap. 4, observing the distances illustrated.
5.2. INSTALLING DW PUMP WITH DN 50 FLANGE (FIG. 6-7) a)
Using the relevant screws, fasten the mount on the sur-faces due to support
the pump; b) screw the delivery pipe onto the mount; c) the mount features a
rod with a guide along which you slide the hook required to lower the pump; d)
lower the motor-driven pump, holding it by the rope fas-tened around the
handle, until the flange slots into place on the mount; e) the motor-driven
pump couples with the mount under its own weight.
STARTING
New pumps may feature a small amount of oil (the food kind), which does not
present a source of health risk.
6.1. VERSION WITH FLOAT (MA-MS) (SEE FIGURE)
Plug into the power mains and/or turn on with the switch: the motor-driven
pump starts working. Once the pump has sucked in enough water to reach the
minimum level (“OFF” level), regulated by the float, it will turn off auto-
matically. The float’s working position is factory set so as to assure a
minimum immersion level in the “OFF” position. NB: If the liquid is overly
contaminated, the operation of the magnetic-type float (MS versions) may be
compromised, meaning it needs to be cleaned on a regular basis. Moreover, do
not use in liquids polluted with iron dust or magnetic material as this would
compromise the operation of the float.
6.2. VERSION WITHOUT FLOAT
Plug into the power mains and/or turn on with the switch: the motor-driven
pump starts working. Once the pump has sucked in enough water to reach the
minimum level, unplug from the power mains and/or turn off with the switch.
6.3. RIGHT- DW PUMPS
a) There is a vent hole on the side of the pump casing of RIGHT and DW
versions for priming. During operation, there will be a small recycling jet
from it.
b) The three-phase version of the DW pumps features a 3-wire + earth power
cord with the addition of two white and grey wires with a smaller cross-
section con-nected to the thermal overload protector inside the mo-tor (FIG.
13). – Connect the power cord’s yellow/green wire to an ef-ficient earthing
system, which must be in compliance with the regulations in force in the
user’s country; – overload protection and use of the signal provided by the
thermal overload protector are the user’s responsi-bility; – overload trip
units must have suitable thermal-magnet-ic devices set appropriately for the
motor-driven pump installed; – for the heat sensor, the two white and grey
wires must be connected to an electrical circuit that can cut power to the
motor-driven pump.
MAINTENANCE
To maintain the motor-driven pumps properly and ensure their long service
life, the filter and/or suction port must not be clogged and the impeller must
be clean. During maintenance work on the motor-driven pumps, dis-connect the
power supply.
7.1. OPTIMA – BEST ONE – ONE VOX MOTOR-DRIVEN PUMP (FIG. 8)
To reach the impeller, proceed as follows: – wear work gloves to avoid cutting
your hands; – unscrew the two screws (1) securing the filter; – remove the
filter (2); – unscrew the two spacers (3) and remove the volute (5); – using a
small straight screwdriver, remove the nylon washers (4) and replace with new
ones; – take care not to damage the 0-ring (6). At this point, the impeller is
exposed: make sure it is clean.
7.2. BEST 2-5 MOTOR-DRIVEN PUMPS (FIG. 9)
To reach the impeller, proceed as follows: – wear work gloves to avoid cutting
your hands; – unscrew the three screws (1) securing the filter; – remove the
filter (2); – unscrew the three spacers (4) and three nuts (5) and re-move the
distancing plate (3); – using a small straight screwdriver, remove the nylon
washers (6) and replace them before reassembling the unit as they break when
the volute is removed; – take care not to damage the 0-ring (7).

7.3. RIGHT MOTOR-DRIVEN PUMP (FIG. 10)
a) If the suction port is clogged, you must clean it, remem-bering to wear
work gloves at all times to avoid cutting your hands;
b) If the impeller is dirty, proceed as follows: – wear work gloves to avoid
cutting your hands; – unscrew the three screws (1) securing the feet and suc-
tion cover side (2) – remove the 0-ring (3); – take care not to damage the
0-ring (3); – make sure the space between the impeller and casing is also
clean.
c) There is a small opening in the pump casing for air vent-ing; keep it
unclogged and clean. It is normal for fluid to come out during priming.
7.4. DW MOTOR-DRIVEN PUMP (FIG. 11)
a) If the suction port is clogged, you must clean it, remem-bering to wear
work gloves at all times to avoid cutting your hands;
b) If the impeller is dirty, proceed as follows: – wear work gloves to avoid
cutting your hands; – unscrew the six screws (1) keeping the pump casing
closed (not the nut as it is welded to the pump casing); – remove the pump
casing, pulling it off (2); – remove the 0-ring (3); – take care not to damage
the 0-ring (3); – make sure the space between the impeller and casing is also
clean.
7.5. REASSEMBLY To reassemble, repeat the procedure given in reverse
order.
