AUTHORISED PERSONNEL
Only people that have the right skills should be al-
lowed to operate, adjust, perform maintenance or re-
pair on DAE Pumps equipment.
It is the responsibility of management to appoint op-
erators with the appropriate training and skill for each
category of job.
Skill level 1: Operator
An operator is trained in all aspects of operating the
unit with the push-buttons, and is trained to know the
safety aspects.
Skill level 2: Mechanical technician
A mechanical technician is trained to operate the unit
the same as the operator. In addition, the mechanical
technician is also trained to perform maintenance and
repair, as described in the instruction manual, and is
allowed to change settings of the control and safety
system. A mechanical technician does not work on
live electrical components.
Skill level 3: Electrical technician
An electrical technician is trained and has the same
qualifications as both the operator and the mechanical
technician. In addition, the electrical technician may
carry out electrical repairs within the various enclo-
sures of the unit. This includes work on live electrical
components.
Skill level 4: Specialist from the manufacturer
This is a skilled specialist sent by the manufacturer or
its agent to perform complex repairs or modifications
to the equipment.
In general it is recommended that not more than two
people operate the unit, more operators could lead to
unsafe operating conditions.
DANGERS WHEN NOT FOLLOWING SAFETY
INSTRUCTIONS
Not observing the safety instructions may lead to per-
sonal injury, damage to the equipment and environ-
mental hazards. Not observing the safety instructions
will void any warranty claim.
SAFETY-CONSCIOUS WORKING METHOD
All safety instructions in this manual as well as na-
tional accident preventing regulations and company-
internal regulations regarding labour, operation and
safety have to be observed.
PERSONAL SAFETY
Stay alert, watch what you are doing and use common
sense when operating a pump. Do not use pumps
while tired or under influence of drugs, alcohol or
medication. A moment of inattention while operating
pumps can result in serious personal injury.
Dress properly. Do not wear loose clothing or jewel-
lery. Contain long hair. Keep your hair, clothing, and
gloves away from moving parts. Loose clothes, jewel-
lery, or long hair can be caught in moving parts.
Use approved safety equipment. Always wear eye
protection, protective shoes and gloves.
SAFETY DURING MAINTENANCE
The owner is responsible for adequate training of the
personnel maintaining the pumps. In principle all
maintenance has to be performed on a non-energised
pump. Observe the procedures as mentioned in the
manual.
ELECTRICAL SAFETY
Pumps must be plugged into an outlet that is properly
installed and grounded in accordance with all codes
and ordinances. Never remove the grounding prong or
modify the plug in any way. Do not use any adaptor
plugs. Check with a qualified electrician if you are in
doubt as to whether the outlet is properly grounded.
Do not abuse the power cable. Never use the power
cable to carry the pumps or pull the plug from an out-
let. Keep the power cable away from heat, oil, sharp
edges or moving parts. Damaged power cables in-
crease the risk of electric shock.
Use a network protected by a ground fault circuit in-
terrupter.
CONVERSION AND SPARE PARTS
Conversions are only allowed after written consent of
the manufacturer. Always use original spare parts.
Unauthorised conversion and / or the use of nonorigi-
nal spare parts will void any warranty claims.
6
UNINTENDED USE
The reliability of the pump is only guaranteed when it
is used according the specifications in this manual.
The limits as indicated are not to be exceeded under
any circumstances.
Do not use the pump to transport water for human
consumption, for water well pumping or for installa-
tion in an explosive atmosphere.
Caustic, slightly inflammable and other explosive
substances such as petrol, petroleum, diluted nitrogen,
greases, oils and waste water from toilets as well as
sludgy water that has a slower flow capacity than wa-
ter, should not be transported using the pump. Salt
water may be transported provided that a zinc anode
kit is used for protection against galvanic corrosion,
see section options.
The temperature of the transported fluids should not
exceed 40°C.
The appliance is not suitable for use as a stationary
installation (such as a lifting device, fountain pump).

General description
Sonora dewatering pumps are electrical submersible
pumps for dewatering applications in construction
sites, industry, mining, tanks, pools etc. The range
consists of several dewatering pumps, all designed for
though pumping in demanding applications. The
compact design and light weight make the pumps very
versatile and easy to install.
The design with outer jacket for cooling and motor
protector keeps the pump running safely under vari-
ous conditions. (Cooling flanges for Sonora S330
provides the cooling function in ab-sence of outer
casing). The double mechanical seal runs in an oil
bath and assures a long life time.
Features:
• Dry running capability. Motor protector.
• Plug and pump.
• Built-in high torque capacitor (1ph).
• The double seal runs in an oil bath and assures a
long life time.
• Impeller from high chrome steel minimizes mainte-
nance.
• The bearings are greased for life with high temper-
ature grease and anti-corrosion additive.
Sonora S330 are compact versatile dewatering pumps
for various pumping needs. The high chrome steel
impeller is designed to handle the water in
construction sites, manholes and industrial pits etc.
with very low risk of clogging.
HOUSING AND WET END
The housing is made of aluminum and parts of wet
end are rubber lined.
IMPELLER
The Sonora S330 pumps are equipped with a high
chrome steel impeller.
OVERLOAD PROTECTION
The pump is supplied with automatically resetting
thermal overload protection switches in the motor
windings.

3081690557 - Float switch kit (CSA)
(Float switch kit for local retro fit assembly.)
Use the pump with a float switch if automatic starting
and stopping is required.
The pump starts if the float switch reaches an angle of
+45° and stops at an angle of -45°.
For continuous operation block the float switch verti-
cally, pointing upwards.
Note! For non CSA pumps with mo-
tor voltage above 400V
, the float
switch kit must be complemented by
a step down transformer as the float
is not approved above 400V.
MOTOR PROTECTION PLUG

3 Indicator lamp for phase control
4 Plug with phase inverter
To protect the motor against over current it is strongly
recommended to use an external motor protector.
For pumps with 400V 50Hz- 3ph motor an external
motor protector can be ordered separately. It com-
bines the on/off switch and the overload protection in
one device, thus creating optimal operating comfort
and protection for the pump.
If the indicator lamp 3 is lighting red, reverse two
phases with a screw driver in plug 4.
After a fault the pump must be restarted manually
pressing the switch on the external motor protector.
SUPPLY CONTROL RELAY
The Sonora pumps can be equipped with a built-in
supply control relay.
Features
Pump protection, the pump will stop in case of:
• Wrong phase sequence.
• Phase failure
A pump equipped with a supply con-
trol relay will not start when phase
sequence is wrong, or in case of
phase failure. To start the pump
when phase sequence is wrong, shift
two of the three phases.

Operating instructions
TRANSPORT
Always use the handle to lift the
pump. Never use the power cable to
lift or transport the pump. Always be
careful not to let it fall or bump it
against the wall or other equipment.
STARTING
The pump may not be used in an ex-
plosive / inflammable environment or
used to pump inflammable liquids!
If the pump is being used for pump-
ing water out of a swimming pool:
• nobody is allowed to be in the pool
during pumping,
• the pump must be connected via a
residual current device having a
rated residual operating current
not exceeding 30 mA.
Check the power cable with mains plug for damage
before every use. If the power cable is damaged, ex-
change it immediately.
Check whether the power supply matches the rating
on the Data plate.
Check whether the fluid to be pumped matches the
characteristics mentioned in section Technical de-
tails.
The minimum start water level is approx.:
150 mm
Never operate the pump without the
strainer.
The Sonora Sludge pumps are de-
signed for solids handling and
there-fore has no strainer.
Rotating parts. Never put your hand
into the volute.
Attach a suitable hose to the outlet and make sure it is
thoroughly tightened. Avoid making excessive bends
in delivery hoses or piping, as this may cause reduced
flow. Turn discharge in horizontal (1) or vertical (2)
direction according to application.
Run the electric cable so that sharp bends are avoided
and there is no danger of the cable being pinched or
otherwise being damaged.
Never install the pump directly on a weak soil layer
or muddy ground. The pump may sink and mud/soil
may enter the pump and reduce the flow. Check that
the pump is pumping.
The start kick can be powerful.
Make sure nobody is close to the
pump during the start.
At start the pump will jerk counter-clockwise when
viewed from above. If direction is wrong, switch po-
sition of two phase conductors.
In case the motor stops due to overload or a blocked
impeller, first pull the plug out of the socket before
removing the pump from the pump site to check for
why the pump has stopped. Remove the blockage, let
the pump cool down and resume pumping.
For Sonora Sludge pumps, water level can be too low
for sufficient cooling. Lay the pump down.
11

STOPPING
Take the plug out of the socket and take the pump out
of the pump site. If the pump has been operating in
dirty water, allow it to run in clean water for a short
period or flush clean water through the discharge port.
If clay, cement or other sticky dirt remain in the pump
this may clog the impeller and seal area.
STORAGE
If the pump is stored more than six months the seal
must be inspected to ensure that it is not stuck before
operation.
To avoid the seal getting stuck it is
recommended to rotate the impeller
every other month.
The pump must be stored in a cov-
ered and dry location free from heat,
dirt and vibrations.

Check the condition of the pump lifting handle and
replace if damaged or worn. Replace any external part
that appears worn or damaged.
MOTOR INSULATION RESISTANCE
Use a 500 V DC Megger and measure the insulation
between the phases and between any phase and
ground. Resistance values should be over 1 M ohm. If
abnormal readings are obtained, immediately hand
the pump in for repair.
Also observe any local requirement regulations. The
stricter one will prevail.
IMPELLER
Inspect the impeller by removing the strainer and dif-
fusor. Replace the impeller if it is damaged or severe-
ly worn.
POWER CABLE
Inspect the cable for cuts, scrapes or sharp bends. If
the outer jacket is damaged, replace the cable. Do not
make splices within wet wells.
