INSTALLATION

Electrical installation

The power supply must meet the specifications on the product.

The pump is intended to be used with either a weatherproof

cable connector or permanently connected to the fixed wiring

of the mains system other than by means of a plug and socket.

A 3 amp fuse must be fitted in the mains circuit.

The cores in the supply cable are coloured in accordance with the following

code: Brown = Live, Blue = Neutral, Green/Yellow = Earth.

The electric cable is permanently connected and sealed in the motor body.

If the supply cable is damaged the pump must not be used and must be safely

discarded.

Do not use the supply cable to lift the pump as this may cause damage.

WARNING - THIS PUMP MUST BE EARTHED

A Residual Current Device (RCD), also know as the Residual

Current Circuit Breaker (RCCB), with a tripping current not

exceeding 30mA must be installed in the supply circuit.

A means of disconnection from the supply having a contact separation

of at least 3mm in all poles must be incorporated in the fixed wiring.

For permanent installations to the mains supply, it is necessary to conform to

the regulations of the national and local electricity authority and this would

include the use of a metal or plastic conduit to protect the cable.

Attention has been drawn to the fact that special rules may exist concerning

the installation of your pond pump (i.e. local building regulations).

These pumps must not be used in swimming pools, or areas where people are

in contact with the water.

Always disconnect the mains electricity supply whilst the equipment is being

installed, repaired, maintained or handled. Consult a qualified electrician if in

any doubt about wiring this product to the main supply.

Warning - The Amphibious pump is provided with a thermal cut

out that temporarily switches off the pump in case of overheating,

the pump may automatically restart when it has cooled.

Amphibious Pump Leaflet 2.qxd 30/3/06 13:33 Page 8

Locating your Amphibious Pump

The Amphibious pump should be located on a firm and level base in the

pond/water feature in a depth of at least 10cm, but no more than 4m.

It is advisable to keep the pump off the bottom of the pond to avoid silt

entering the pump causing excessive wear and increasing pre-filter cleaning.

Never run the pump out of water as this may cause irreparable damage.

Fountain

Make sure there is ample cable from mains supply. Place pump in desired

location. Adjust telescopic riser pipe so fountain head is above surface of

the pond. Fountain height can now be adjusted, see "Adjusting dual control

T-piece" diagram below. The fountain ball joint can be used to adjust for uneven

pond floors ensuring the fountain display is kept vertical and within the pond.

See "Getting to know your Amphibious pump" fittings for parts and descriptions.

Tip: Ensure that any fountain, waterfall, filter or feature fitted does not empty water out of

pond/water feature. In windy conditions it may be necessary to shut off or reduce the

height of your fountain display to prevent water loss. Also see the explanatory diagram on

the top face of your Amphibious pump carton.

Warning - Failure to carry out routine maintenance leaving the

pump under reduced or no flow conditions for long periods

(e.g. blocked pre-filter) will result in a shorter pump life and will

invalidate the guarantee.

Blagdon Amphibious pumps are centrifugal pumps with a magnetic impeller

movement driven by a watertight asynchronous motor. They require minimum

cleaning, only periodic cleaning of the pre-filter and impeller is necessary.

Cleaner

The use of Blagdon Pond Pump Cleaner will give improved performance and

pump life by removing built-up lime scale and waste. Use before dismantling

for easier, cleaner handling.

Tip: New ponds and ponds in hard water areas will cause lime scale to build-up more

quickly. Dip your pump more frequently with Blagdon Pond Pump Cleaner to maintain

optimum performance.

MAINTENANCE & CLEANING

INSTALLATION

Water Feature / Filter / Waterfall

Install as for Fountain. Depending on water feature to be supplied, your Amphibious

pump can be used with the dual control T-piece 1"

/4"

/2" hose fitting (see

"Adjusting dual control T-piece" diagram). Hose clips should be used to secure hose.

Tip: The larger 1” hose fitting will give maximum pump flow performance. If you do not

require a fountain a significant increase in performance will be gained by connecting the

hose fitting directly to the pump outlet flange.

• Ensure pipe work is not blocked, leaking or is laid so that it gets crushed

or kinked.

• Keep the height that water is to be pumped from the water surface (called

Head) to a minimum. The higher the head the lower the flow rate and the

more wear on the pump.

• Use the largest diameter, smoothest bore pond hose over the shortest

distance and keep hose fittings to a minimum. This removes frictional loss

of flow and so increases pump flow rates.

Also see the explanatory diagram on the top face of your Amphibious pump carton.

Amphibious Pump Leaflet 2.qxd 30/3/06 13:33 Page 10

MAINTENANCE & CLEANING

Remove the pump motor from the impeller/rotor housing by holding the housing

while turning the motor clockwise (see arrows provided on the pump).

Dismantle the Impeller/Rotor assembly by undoing the centre bolt ensuring the

washer is kept in a safe place. NB: THIS IS A LEFT-HAND THREADED BOLT SO

MUST BE UNSCREWED IN A CLOCKWISE DIRECTION (THE OPPOSITE TO A

NORMAL THREAD DIRECTION). Remove the ceramic thrust washer, the ceramic

shaft and the impeller rotor assembly from the impeller/rotor housing.

Clean all parts of the impeller in fresh water ensuring that the impeller vanes and

impeller inlet are clean.

MONTHLY MAINTENANCE

Routine Maintenance

Carry out routine maintenance when pump flow is visibly reduced.

1. Switch off electricity to the pump, and all other electrical pond equipment.

2. Remove pump from pond (do not use the cable to lift the pump).

3. Open pre-filter by unscrewing the pump flange from the outlet of the pump

and opening the pre-filter lock with a coin.

4. Remove pump (see getting to know your Amphibious Pre-Filter). Wash the

pre-filter and impeller inlet thoroughly in fresh water.

A blocked pre-filter and impeller inlet will reduce the pump flow rate.

Monthly Maintenance

Follow steps 1 to 4 as per Routine Maintenance.

The impeller and impeller inlet can become blocked by pond waste.

Clean the impeller according to the following instructions.

Follow steps 1 to 4 as per Routine Maintenance.

Amphibious Pump Leaflet 2.qxd 30/3/06 13:33 Page 11

MAINTENANCE & CLEANING

Fit the ceramic shaft to the pump housing with the radial groove and chamfered

end towards the pump housing. The shaft and its location in the pump housing

must be clean with no dirt or debris trapped between them. Trapped dirt may

affect the alignment of the impeller, which may damage the pump.

Slide rotor / impeller over ceramic shaft (with the impeller towards the pump

housing).

Lay ceramic thrust washer on top of the shaft. The faces of the shaft and thrust

washer must be clean. Any trapped dirt may cause uneven wear of the ceramic

washer and may allow the rotor to damage the pump.

Fit the centre bolt through centre holes of ceramic washer and shaft, ensuring the

copper centre bolt washer is fitted between the head of the bolt and ceramic thrust

washer.

Carefully tighten the LEFT HAND THREADED BOLT to a maximum torque of 2Nm.

The Impeller assembly should rotate freely after tightening. If it does not, dismantle

and re-check.

DO NOT LUBRICATE THE ROTOR ASSEMBLY WITH ANYTHING OTHER THAN

CLEAN WATER

Ensure impeller/rotor housing O ring seal is correctly seated in its recess and

reassemble motor to pump housing assembly. If the motor to pump housing is

difficult to fit, lubricate the O ring with clean water only.

The impeller assembly consists of the impeller/rotor, ceramic shaft, centre bolt,

copper washer, ceramic thrust washer and sealing O ring. Replacement impeller kits

are available for all models in the range.

Annual Maintenance

Following as for routine and monthly maintenance, once a year you should

service your pump by using Blagdon Pond Pump Cleaner, (this may need to be

done more frequently in hard water areas).

Dismantle pump and examine all parts for wear or damage, replacing any

parts that show obvious wear and/or damage. (See "Getting to know your

Amphibious Pump" for parts/description and replacement parts codes.)

Particular care should be taken to examine the cable entry point and the cable;

if there is any sign of damage the pump should be discarded and safely

disposed of.

Winter Storage

The pump can be run in the pond during the winter but care should be taken

to ensure that it is fully immersed and cannot freeze solid. If the pump is not

used during the winter, follow annual maintenance procedure and store frost-

free in the house or garage until spring.

All maintenance outlined in this booklet must be carried out by competent

personel.

The Amphibious Pump is suitable for use in garden ponds at water

temperatures above freezing and below 35˚C.
