Davey XJ Ultra User Manual

Agoodqualitynon-returnvalvemustbeinstalled
inthepressurepumpoutletpipeworkbeforethe
hotwaterservice.Failuretoinstallthisnon-return
valvemayresultinpumpdamage.Suchdamage
isnotcoveredbyguarantee.
Connection of Mains Scheme or Town Wa-
ter Supply to either Suction or Discharge of
Pumps & Pressure Systems
MostWaterSupplyAuthoritieshavestrictregu-
lationsregardingdirectconnectionofpumpsto
mainswatersupplies.Inmostcasesanisolating
tankisrequiredbetweenmainssupplyandpump.Daveyalsorecommendthis
method.Directlyappliedmainspressurecanexceedpumpoperatingpressure
anddamagepump.

Connection to your Water Source
BELOW GROUND WATER SOURCES
Whenevertheinstallationpositionofthepumpishigherthan1m(3.3ft)above
thelowestwaterlevel,afootvalvemustbeusedontheendofthesuctionpipe
asillustratedin(C)below.Ensurethatthefootvalveisatleast

metrebelow
minimumwaterlevel.
SPEAR POINT INSTALLATIONS
WhenaDynajet®isinstalledonaspearorwellpoint,acheckvalvemustbe
ttedimmediatelyontopofthespearpointitself,asshownin(D)above.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.

WARNING: Some insects, such as small ants, nd electrical devices
attractive for various reasons. If your pump enclosure is susceptible
to insect infestation you should implement a suitable pest control plan.
Choosing a Site
Chooseasitewitharmbaseandasclose
tothewatersourceaspossiblewithcorrect
powersupply.Makesureyourpressure
systemisalwaysconnectedtoanadequate,
reliablesourceofcleanwater.
Housing your Davey Pressure System
Toprotectyourpressuresystemfromtheweather,
makesurethepumphouseisbothwaterproof,
frostfreeandhasadequateventilation.Thepump
shouldbehorizontallymountedonarmbase
allowingfordrainage,toavoiddamagetoooring
etc.,thatovertimemayoccurfromleakingpipe
jointsorpumpseals.Donotmountthepump
vertically.
Pipe Connections
ForbestperformanceuseP.V.C.orpolythenepipesatleastthesame
diameterasthepump’sinletanddeliveryoutletopenings.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.Topreventstrain
onpumpthreadsalwayssupportheavyinletandoutletpipes.Ifthereisa
likelihoodthewatersupplymaycontainsolidparticlessuchaspiecesofplant
orvegetablematter,asuctionstrainer
shouldbeinstalledbeforethepumpto
avoidblockingofthepump.Laysuction
pipeataconstantgradienttoavoid
airpocketswhichmayreducepump
efciency.
Where to use Check Valves and Foot Valves
Installationswithasuctionliftover1mrequire
agoodqualityfootvalvetoavoidlossofprime.
Inthiscase,thepoppetvalveinsidethepump
shouldberemoved.Installationswithooded
suctionrequireagatevalvesowatersupplycan
beturnedoffforpumpremovalandservicing.
Priortousingthispumpyoumustensurethat:
• Thepumpisinstalledinasafeanddryenvironment
• Thepumpenclosurehasadequatedrainageintheeventofleakage
• Anytransportplugsareremoved
• Thepipe-workiscorrectlysealedandsupported
• Thepumpisprimedcorrectly
• Thepowersupplyiscorrectlyconnected
• Allstepshavebeentakenforsafeoperation
AppropriatedetailsforalloftheseitemsarecontainedinthefollowingInstallationand
OperatingInstructions.Readtheseintheirentiretybeforeswitchingonthispump.Ifyou
areuncertainastoanyoftheseInstallationandOperatingInstructionspleasecontact

Power Connection
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.
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 Dynajet®
XJ pump is designed to handle clean water. It should not be used for any other purpose
without specic referral to Davey. The use of the pump to handle ammable, corrosive
and other materials of a hazardous nature is specically excluded.
Do not use this pump to pump ammable uids, such as petrol or
diesel fuels.
Do not use pipe thread sealing compounds on any part of this pump.
ONLY use Teon sealing tape.
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.
IMPORTANT
For Automatic Pressure Pumps Installed with a Mains Pressure Hot
Water System.
Abrasive Materials
The pumping of abrasive materials will cause damage to the
pressure system which will then not be covered by the guarantee.
Spear point ow capacities vary considerably. Check with the supplier
to ensure the pump and spear point are correctly matched.
