Clarke IVP13A Installation and operation manual

1103

Thank you for purchasing this Clarke Submersible Pump.
This highly efficient centrifugal pump is designed for pumping clean water, or water
containing sand or solids in suspension, up to a maximum 12mm in diameter, (please see
Pump Features, page 6).
It is ideally suited for draining ponds, pools, cellars, drains, building excavations , etc., where
water temperature does not exceed 50°C. Additionally, due to its compact shape, ease
of manoeuvrability, and its vertical delivery port, it is ideally suited for emergency uses such
as drawing water from tanks or rivers, excavations, flooded underpasses etc.
The pump is NOT suitable for pumping salt water, aggressive or chemical substances, or for
permanent installation in fish ponds, as the acidity, found in fish ponds, will damage the
pump seals. It MUST NOT be used for pumping hydrocarbons (petrol, diesel fuel, oils, solvents
etc.).
Before using the pump, please read this instruction manual thoroughly and carefully follow
all directions given. This is for your own safety and for that of others around you, and will
also help you achieve long and trouble free service from your pump.

SAFETY PRECAUTIONS
1. This pump is designed to pump WATER ONLY. Never use for pumping
flammable liquids or chemicals of any kind.
2. NEVER allow the pump to run dry.
3. An approved Residual Current Device (RCD) MUST be used when pumping
from ponds or swimming pools.
4. Your submersible pump may ONLY be used for pumping water from a swimming
pool when there is no person or animal in the pool.
5. ALWAYS disconnect the pump from the electrical supply
before placing into, or removing from water, and
before any cleaning or maintenance.
6. When raising or lowering the pump, ALWAYS use
a rope or chain attached tothe handle. NEVER
lift or carry the pump by the mains cable or the
float switch cable.
7. DO NOT run the pump with the body exposed
for longer than 10 minutes.
8. DO NOT install the pump on sand, silt, mud etc.,
or ground which is likely to shift.
9. If pumping water which is liable to freeze, the pump MUST
be run continuously, otherwise the pump must be
removed from the water and stored in a frost free location.
10. If the pump is to be used where there may be silt or mud (e.g., garden ponds),
ALWAYS keep the pump clear of any sediment by standing it on a platform or
bricks or suspending from a rope or chain attached to the handle.
11. DO NOT use for permanent installation in pumping clean or pure water,
(particularly drinking water), as there is the remote risk of contamination, should
there be a leak in the seal device.
12. If the mains cable becomes damaged, it MUST be replaced - NOT repaired.
(see Electrical Installation).
13. If used in a confined space - in a shaft or sump etc., ENSURE the float has
sufficient room to operate correctly (see Installation on page 7).
WARNING
Failure to comply with these safety precautions could be extremely
hazardous, not only causing a risk to personal safety but also damage to
the pump, which could invalidate your guarantee.

ELECTRICAL CONNECTIONS
The mains lead should be connected to a standard 230Volt (50Hz) electrical supply
through an approved 13Amp BS 1363 plug or a suitably fused isolator switch. We
recommend that the pump be connected via a Residual Current Device (RCD).
I MPORTANT:
If used for draining swimming pools or ponds, it is mandatory that the pump be
fitted with a Residual Current Device (RCD), with a rated residual operating current
of no greater 30mA.
If the pump is to be connected to an outdoor electrical supply, make sure that
both the plug and the socket are of a BS approved waterproof design.
In the event that the pump is hard wired into the electrical system, it must be
carried out in accordance with IEE regulations.
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in the mains lead are coloured in accordance with the
following code:
Green & Yellow - Earth
Blue - Neutral
Brown - Live
As the colours of the flexible cord of this appliance may not correspond with the
coloured markings identifying terminals in your plug proceed as follows:
Connect GREEN & YELLOW cord to plug terminal marked with a letter “E” or
Earth symbol “ ” or coloured GREEN or GREEN & YELLOW.
Connect BROWN cord to terminal marked with a letter “L” or coloured RED
Connect BLUE cord to terminal marked with a letter “N” or coloured BLACK
FUSE RATING
The fuse in the plug for this appliance must be rated at 13 amps.
If this appliance is fitted with a plug which is moulded onto the electric cable (i.e.
non-rewirable) please note:
1. The plug must be thrown away if it is cut from the electric cable. There is a
danger of electric shock if it is subsequently inserted into a socket outlet.
2. Never use the plug without the fuse cover fitted.
3. Should you wish to replace a detachable fuse carrier, ensure that the correct
replacement is used (as indicated by marking or colour code).
4. Replacement fuse covers can be obtained from your local dealer or most
electrical outlets
5. The fuse in the plug must be replaced with one of the same rating (13 amps)
and this replacement must be ASTA approved to BS1362.

6
If the power cable becomes damaged, IT MUST BE REPLACED, DO NOT REPAIR.
Return the pump to your Clarke dealer, or contact Clarke Service Department on:
020 8988 7400
IMPORTANT:
If you are in any doubt regarding electrical installation, you should consult a
qualified electrician. DO NOT attempt any electrical repairs yourself.
PUMP FEATURES
The pump is of rugged and durable construction, designed for long lasting
continuous operation and its’ stainless steel body provides good anticorrosive
properties. The motor is provided with built in overload protection.
For your information, the chart on page 10 shows the flow rate for the pump at
various heads. (HEAD is the distance, or height, from the surface of the water to
the point of discharge)
The pump is designed to pump water containing solids in suspension. That is - with
a maximum of 5% solid content, and a maximum 12mm solid dia.
It is NOT designed for pumping slurry, sludge, mud or heavily polluted water, and
should NOT be used for permanent installation in fish ponds or any water containing
chemicals or other acidic contaminants including salt water.
Whenever the pump is used to pump contaminated water, e.g. to drain fish ponds
etc., you must ALWAYS immerse the pump in clean water and run it for a few
minutes on completion to ensure it is completely cleansed of all contaminants.
The maximum depth to which the pump should be submerged is 10 Metres.
The pump is fitted with a Float Switch and is suitable for permanent or semi-
permanent installations, e.g. installations where it is necessary to maintain a water
at a particular level.
As the water level rises, so will the float. At a certain point the switch will operate
and start the pump. As the water level falls, so will the float until the switch operates
again and stops the pump.
Float switches are adjusted at the factory to provide the correct ON-OFF switching
mode, however, you can adjust the level at which the pump cuts in and out by
sliding the float switch cable through the clip attached to the main body. Shorten
or lengthen it as the case may be. The shorter it is, the earlier the pump will cut out,
and the water therefore will be deeper at this point. Similarly, it will cut in earlier
and the water will therefore be shallower when it does so.
It should not normally be necessary to change the length of cable (from the clamp
to the float switch), but should you do so, remember that the cable length should
NEVER be so long that the float switch fails to operate and switch the pump OFF.
ALWAYS check its operation before use.
Similarly, the cable length must not be so long so as to allow the water level to
drop below the level of the top of the strainer.

INSTALLATION
The pumps’ delivery outlet is provided with a 1.5” BSP female thread, for connection
to a suitable adapter (not provided). It is advisable to seal the thread with PTFE, or
similar tape, to ensure maximum performance from your pump.
The delivery hose used should be of the same ID as the delivery outlet and
completely sound. Any holes, no matter how small, will reduce the efficiency of
the pump, or even prevent the pump from delivering water at all. Smaller diameter
hose will reduce capacity and put additional strain on the motor.
Where it is necessary for long horizontal stretches of delivery hose to be used, the
hose ID should be greater than that of the delivery outlet.
Having connected the delivery hose, secure a suitable length of rope or chain to
the pump handle, and plunge the pump into the water.
The pump must be in a vertical position on a solid flat surface. If this is not available,
sit the pump on house bricks, or something similar, and ensure that this type of
support is not likely to shift.
The pump should be well clear of silt, mud or any type of marine growth.
IMPORTANT:
ALWAYS raise and lower the pump using a rope attached to the lifting
handle, NEVER by the power cable.
7
Ensure the sump, or bore hole, has
adequate dimensions so as not to restrict
the movement of the float switch (see
fig.1 for recommended minimum size).
The calculation, for the dimensions of the
bore hole, must also take into account
the quantity of water arriving and the
pump flow rate, so as not to subject the
motor to excessive starting operations,
bearing in mind, the pump should not be
started more than 20 times per hour.
Take all necessary precautions as
described on page 4 before plugging in,
and switching ON.
NOTE:
a. The symbol on the pumps’ Rating Plate, denotes the MAXIMUM depth to
which the pump may be submerged, in metres.
b. When the pump is used in a permanent or semi-permanent installation, a
check valve MUST be fitted in the delivery pipe.
IMPORTANT: In such situations, care must be taken to ensure that all air is
expelled from the delivery side of the pump when immersing in water.

MAINTENANCE
WARNING
Before checking the condition of the pump, ensure it is unplugged from the
mains supply. If the unit is hard wired, ensure the circuit breaker is open.
The pump should require no maintenance other than regular cleaning. Its’
mechanical seal is lubricated in an oil chamber, and its’ bearings are ‘sealed for
life’. If the pump starts to show signs of wear or damage, contact your CLARKE
dealer for advice. Do not use the pump if there is any damage to the mains
supply cable, or to the float switch or its cable.
Check the pump installation regularly to ensure the base inlet is clear of leaves or
other debris.
Note that the pump is fitted with automatic thermal overload protection. If it
overheats due to an obstruction in the pump, or pumping warm water in excess
of 50oC for example, it will shut off automatically. Switch the pump OFF and
disconnect from the mains supply. Check for blockages and allow the motor to
cool (at least 15 minutes) before attempting to restart.
Do not attempt to repair the pump yourself, as you may damage the seals and
invalidate your guarantee. Repairs must be carried out by a qualified pump
engineer, your CLARKE dealer, or contact the CLARKE Service Department, on:
020 8988 7400
If the pump becomes badly clogged, the stainless steel strainer may be removed
and cleaned by removing the three screws FROM THE BASE ONLY. DO NOT attempt
to remove any other screws.
Backflush the pump chamber by directing a jet of clean water through the outlet
port.
WARNING:
Do not attempt to strip the pump further as this will invalidate the guarantee
ANNUALLY OR EVERY 2000 WORKING HOURS (Whichever is sooner)
The sealing oil must be checked by a qualified pump engineer. Consult your Clarke
dealer, or Clarke International Service Department.

TROUBLE SHOOTING
A. PUMP WILL NOT START
1. Check to ensure Power is switched on.
2. Check fuse (consult an electrician if in doubt).
3. If extension lead is fitted, check connections (consult an electrician if
in doubt).
4. Internal thermal cutout has not reset. Leave for 15 minutes and try again.
5. The Impeller may be jammed. Disconnect from the mains supply, remove
the bottom strainer and remove any objects that may be obstructing the
impeller. Replace the strainer and try again.
6. Float switch may be jammed against side wall or prevented from moving.
7. Water level too low - float switch in OFF position - Lift float to check
switch.
If the pump still fails to start, consult your CLARKE dealer for advice.
B. PUMP WILL START BUT NOT PUMP
1. Check to ensure strainer is not blocked - clean as necessary
2. Discharge tube clogged or obstructed - clear as necessary.
3. The head may be too great, i.e. you are trying to lift the water too great a
distance for the pump to cope with. (See specifications pages 10 ).
4. Impeller may be damaged - Consult your CLARKE dealer
C. PUMP WILL NOT STOP
1. Float switch may be prevented from moving to the fully down position.
2. Float switch may be faulty. Consult your CLARKE dealer for advice.
D. PUMP STOPS RUNNING
1. Thermal overload has operated. If this condition persists, investigate the
cause. Are you attempting to pump liquid which is too dense for the pump
(mud, slurry etc.), or too high a temperature.
2. Pump has run dry, or float switch has cut in.
3. A foreign object has jammed the impeller.
