Damage prevention and safety instructions (See figure 4)
| A | Warning! Observe limitations of use. |
|---|---|
| 3 | The name plate voltage must be the same as the mains voltage. |
| C | Connect the pump to the mains via an omnipolar switch with at least a 3 mm |
opening between contacts.
Install a high-sensitivity differential switch (0.03A) as extra protection
against lethal electric shocks.
0| If the supply cord is damaged, it must be replaced by an A.T.S.
E| Connect the pump to the ground.
F| Use pump only within performance limits indicated on the name plate.
G| Remember to prime pump.
H| Check for motor self-ventilation.
I| This apparatus may be used by children 8 years or older and persons with
reduced physical, sensory or mental capacities, or lacking experience and
knowledge, if they are supervised or receive adequate training on the safe use
of the apparatus and understand the dangers. Children should not be allowed to
play with the apparatus. Children should not perform the ordinary cleaning and
maintenance tasks without supervision.
J| Be careful with hazardous liquids and environments.
K| Caution! Look out for accidental leaks.
Do not expose pump to bad weather.
L| Caution! Avoid icing.
Cut out power supply before servicing pump.
Safety precautions
This symbol together with one of the following words “Danger” or “Warning”
indicates the risk level deriving from failure to observe the prescribed
safety precautions:
DANGER risk of electric shock
Warns that failure to observe the pre cautions involves a risk of electric
shock.
DANGER Warns that failure to observe the pre cautions involves a risk of
damage to persons and/or things.
WARNING Warns that failure to observe the pre cautions involves the risk
of damaging the pump and/or the facility
GENERAL INFORMATION
Please observe the following instructions to achieve the best pump performance
possible and a trouble free installation.
Read these instructions before installing the pump.
Save them for future reference.
These are single cell centrifugal pumps with built-in filter elements,
especially designed for prefiltering and recirculation of water in swimming
pools.
These pumps are designed to operate with clean water, free from particles in
suspension and with a maximum temperature of 40ºC.
Correct pump operation is assured providing the instructions on electrical
connection, installation and use are strictly adhered to.
Failure to adhere to the instructions can result in premature failure of the
pump and voiding of the warranty.
HANDLING
The pumps are supplied suitably packaged to prevent damage in transit. Before
unpacking, checkthat the packaging has not been damaged or deformed,
Lift and handle the product with care and withthe right tools.
INSTALLATION
The installation of these electric pumps is only permitted in swimming pools
or ponds that comply with standards IEC 60364-7-702 and/or the national
regulations of the country in which the product is to be installed.
3.1. Fixing
The pump should be installed on a solid, horizontal base, secured by screws or
bolts and using the existing holes in the mount.
The pump should be protected from possible flooding and receive dry
ventilation.
3.2. Suction pipe assembly
The pumps must be installed at least two meters from the wall of the pool, and
at the same height as the level of the water, or if possible, below. The end
of the suction pipe must always remain at least 30 cm below the water level.
The suction pipe, if longer than 7 meters, must be of the same or greater
diameter than the pump inlet and installed in an upward inclination to prevent
trapped air pockets forming. If the pump is required to perform a suction
lift, to avoid unnecessary losses of head on the discharge side, the pump
should be installed as close as possible to the water. It is not advisable to
install the pump at more than 3m geometrical height from the water level.
3.3. Discharge pipe assembly
It is recommended to use pipes with a diameter equal or greater than the pump
outlet. This will reduce loss of head caused by friction in longer pipe runs.
Pipework must be supported and their weight must not rest on the pump.
3.4. Electrical connection
The electrical installation must have a multipole isolator with minimum 3 mm
contact openings, The protection of the system will be based on a differential
switch (Δfn = 30 mA)
The power cable must correspond at least to the type H07 RN-F (according to
60245 IEC 66) and having terminals.
The connection and its dimensioning must be performed by a qualified installer
according to the needs of the facility and following the regulations in force
in each country.
The power supply socket for the apparatus must be at least 3.5m from the pool.
Single-phase motors have thermal protection.
All of three phase motor pumps do not incorporate this protection. They must
be connected to a motor-protective circuit breaker that can be adjusted
manually. Set the circuit breaker according to the current given in the rating
plate plus 10%. Follow instructions given on fig.1 for correct electrical
connection.
3.5. Pre-start checks
Ensure the voltage and frequency of the supply corresponds to the values
indicated on the electrical data label.
Ensure that the pump shaft is rotating freely. Fill the pump body with water
through the filter cover to the bottom level of the suction line. Check all
joints and connections for leaks. Set the prefilter cover back in place and
screw it to a suitable tightness. THIS PUMP MUST NEVER BE DRY RUN.
STARTING
Ensure all valves in the pipework are open.
Connect power supply. There will be a delay before water appears at the end of
the discharge pipe. Viewings from the fan ensure that the rotation of the
motor is clockwise. On three phase pumps the motor may rotate anticlockwise.
If this is happening, the flow will be lower than expected. To rectify this
situation the two supply phases need to be reversed. Ensure that the absorbed
current is the same or lower than the maximum shown on the name plate. Adjust
the thermal relay if is necessary. If the pump fails to operate refer to the
possible faults, causes and solutions list for assistance.
MAINTENANCE
Under normal conditions these pumps require no special or planned maintenance.
Clean the pump with a damp cloth without using harsh products.
If the pump is not to be operated for a long period it is recommended to
remove it from the installation, drain down and store in a dry, well
ventilated place.
ATTENTION: In the event of faults or damage occurring to the pump,
repairs should only be carried out by an authorised service agent. The
Official Technical Services list is in
www.espa.com.
DISPOSING OF THE PRODUCT
When the pump is eventually disposed of, please note that it contains no toxic
or polluting material.
All main components are material identified to allow selective disposal.
This product or parts of it must be disposed of in an environmentally sound
way, use the waste collection service. If this is not possible, contact the
nearest ESPA service workshop.
