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
in the main system other than by means of a plug and socket.
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.
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.
INSTALLATION
For permanent installations to the mains supply, it is necessary to conform to
the regulations of the 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 Hydratech Multi pump is provided with a
thermal cut out that temporarily switches off the pump in case
of overheating and the pump may automatically restart.

Warning - Failure to carry out routine maintenance leaving the
pump under reduced or no flow conditions for long periods
(i.e. blocked pre-filter cage) will result in a shorter pump life
and will invalidate the guarantee.
Blagdon Hydratech Multi pumps are centrifugal pumps with a magnetic
impeller movement driven by a watertight synchronous motor. They require
minimum cleaning, only periodic cleaning of the pre-filter cage 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 and cleaner handling.
Routine Maintenance
Carry out routine maintenance when pump flow is visibly reduced.
1. Switch off electricity.
2. Remove pump from pond (do not use the cable to lift the pump).
3. Open pre-filter cage and remove pump (see page 2). Wash thoroughly in
fresh water. A blocked pre-filter cage will reduce the pump flow rate.
MAINTENANCE & CLEANING
8 9
Locating your Hydratech Multi
The Hydratech Multi 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 2m.
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.
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 (not 800 model). See “Getting to know your
Hydratech Multi” for parts and descriptions.
Tip: Ensure that any fountain, waterfall, filter or feature fitted does not empty
water out of pond/water feature.
INSTALLATION INSTALLATION
BELL FOUNTAIN
Adjust bell by
moving head
higher for small
bell and lower for
a wider bell shape.
ADJUSTING DUAL CONTROL ‘T’ PIECE
AND TELESCOPIC RISER PIPE
Adjust height by pushing or
pulling 24cm telescopic riser pipe.
17cm extension pipe can be added
if required (see “Getting to know
your Hydratech Multi” for parts
descriptions).
1” OUTLET FLOW
CONTROL VALVE
Supply water features,
waterfalls and filters by
adding 1” hose. Adjust flow

Water Feature / Filter / Waterfall
Install as for Fountain. Depending on water feature to be supplied, your Hydratech
Multi can be used with the dual control ‘T’ piece 1" hose fitting (see “Adjusting
dual control ‘T’ piece” diagram). Hose clips should be used to secure hose.
Tip: The larger 1" hose will give maximum performance when fitted to the
Hydratech Multi 1500, 2500, 3250, 4000 or 6000.

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
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. On models 1500, 2500, 3250
and 4000 also check ‘O’ ring seal (see diagram below)
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.

your retailer.
GUARANTEE
IMPORTANT
Problem
Low flow from pump
1. Follow routine cleaning procedure.
2. Follow monthly cleaning procedure.
3. Ensure pipe work is not blocked, leaking or is laid so that it gets crushed
or kinked.
4. 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.
5. 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.
Poor fountain performance
• Reduced height.
• Jets blocked.
Clean flow adjuster and fountain
head. Wash under a tap or hose.
Blagdon Pond Pump Cleaner
should be used to remove lime
scale build-up/waste (see diagram)
for improved results.
No flow from pump
1. Check power supply is on.
2. Check fuse and wiring (SEE ELECTRICAL INSTALLATION).
3. Follow low flow procedure as above.
If none of the above works contact Interpet (Blagdon) Consumer Advice
Department (See Faults problem procedure Page 13).
TROUBLESHOOTING

DAISY
To clean, remove
head and rinse.
Or in hard water
areas, use Blagdon
Pond Pump Cleaner.
