Davey HS50-06 User Manual

IP55 Compliant Connection
Forsomeinstallations,suchaswetareasindairies,thepumpisrequiredtobe
IPX5compliant.TheDynaoHSpumpisIP55compliant.
Pipe Connections
For best performance use P.V.C. or
polythene pipe at least the same
diameter as the pump’s inlet. Larger
diameter pipe may be used to minimise
resistancetoowwhenpumpinglonger
distances.
Use unions at pipe connections to enable easy
removalandservicing.Usesufcienttapeto
ensureairtightsealandhandtightenonly,do
notscrewconnectionsallthewayintosuction
port.Topreventstrainonpumpthreadalways
support heavy inlet and outlet pipes.
Lay suction pipe at a constant gradient to avoid
airpocketswhichmayreducepumpefciency.
Connection to your Water Source
ABOVE GROUND WATER SOURCES
Installationswithoodedsuctionrequireagatevalvesowatersupplycanbe
turned off for pump removal and servicing.
Leavethein-builtone-waycheck
valveinstalledtoavoidwaterdraining
backpastthepumpwhilenotin
operation and causing possible pump
damage.

level,afootvalvettedtotheendofthesuctionpipeasillustratedin(A)below
is required. Ensure that the foot valve is at least
1

SPEAR POINT INSTALLATIONS
WhenaDynaoHSisinstalledonaspearorwellpoint,thein-builtcheckvalve
MUSTberemovedandacheckvalvettedimmediatelyontopofthespear
pointitself,asshownin(B)above.
Removal of in-built check valve (wheretted)
If your installation requires the removal of the in-built check valve or the in-
builtcheckvalverequiresremovalforservicing,thiscanbeachievedwithout
difculty.
Thein-builtcheckvalveisacassettedesign,whichisscrewedinthroughthe
suction inlet.
Removal of the check valve cassette is achieved by inserting any suitable tool
(eg:apairofpliersorthehandlefromanadjustingspanner)intotheinlet.
Thecheckvalvecassettehasvariousribsandrecessestoallowavarietyof

Before installing your new pump, please read all instructions carefully as failures
caused by incorrect installation or operation are not covered by the guarantee.
Your Dynao HS Electric Pump is designed to handle clean water. The pump
should not be used for any other purpose without specic referral to Davey.
The use of the pump to pump ammable, corrosive and other materials of a
hazardous nature is specically excluded.
Connect lead to power supply designated on pump label, do not
use long extension leads as they cause substantial voltage drop,
poor pump performance and may cause motor overload.
The electrical connections and checks must be made by a
qualied electrician and comply with applicable local standards.
DO NOT USE THREAD SEALING COMPOUNDS, HEMP OR PIPE
DOPE!
NOTE: Suction leaks are the largest
cause of poor pump performance
and are difcult to detect. Ensure
all connections are completely
sealed using thread tape only.
DO NOT USE SEALING COM-
POUNDS OR PIPE DOPE.
NOTE: DO NOT install the check valve at the pump or at the top of
the well. DO NOT run the pump without water.
NOTE: Be certain to select the spear point to suit the well conditions
and regulate the ow rate from the pump accordingly.
NOTE: Prior to installation remove the red transport plugs & associated seals from
the suction and/or discharge ports.
NOTE: HS models are tted with an in-built suction check valve
which should be removed on all suction lift applications and a
foot valve or check valve installed in the suction pipework as
appropriate.
