Stainless Steel Submersible Pump- Brochure

30 equally spaced6 mm50°C continuous duty3 mm7 m with 10 mt. of power cordCHAP.1 FEATURESDRENOX® range pumps are particularly suitable to pump rain water, drain water; they are used to de-water flooded rooms, toirrigate gardens and back yards, to transfer clear or muddy water, with pumps operating totally or partially immersed.Each pump is tested and packed very attentively.Please ensure pump has not been damaged during transport; if this occurs please phone the dealer, within 8 daysfrompurchasing day.CHAP. 2 USE AND HIS LIMITATIONSMAX.

(See Pict. 1A-1B ref.A)DRENOX® 80/7 can drain water up to 3mm. from ground, once pump is priming . (See Pict. 1A ref.B)Single phase versionSingle phase pumps are equipped with double ground contact plugs at top end of supply cord ; in this case grounding is done whenplugging in.Three phase versionIn this case the ground wire ( yellow-green cable ) of supply cord must be connected to ground wire of electric current network.Ensure connection to electric current network by using an omnipolar-sectionned magneto thermic circuit-breaker.This will ensure effective disconnection from electric current network.The linear express measures in chart are in millimeters Please refer to Pict. 1A and Pict. 1B CHAP. 3 INSTALLATIONWhen installing, please ensure pump is disconnectedfrom electric current network. DANGER Electric shock riskPlease use handlebar to remove or lift pump up.Please use a non-return valve in case pump is connected to fixed installation with rigid piping; this will avoid liquid circulating whenpump has been turned off; use of a pipe fitting will allow easy disconnection of pump for maintenance.Dimensions of drain well must allow max. 30 on/off cycles/hour. ( See USE AND HIS LIMITATIONS )Please use flexible pipe connected to pump by means of plastic fitting in case of temporary use of pump. Use a rope to immerse pump and fasten it to pump's handlebar.DRENOX® is equipped with a pre-rated float switch ( See Pict. 1/A and 1/B ); please increase or decrease the free piece of floatswitch cable by making it sliding through the proper seat on the handlebar, when modifying the rating of float switch.Pumps used besides or inside swimming pools, garden ponds or similar places may have special requirements. CHAP. 4 ELECTRIC CONNECTIONElectric shock riskDANGERInstaller must make sure that electric current networkhas ground wire conforming to current laws.Make sure that electric current network is provided with ahigh-sensitivity circuit-breaker =30 mA (DIN VDE 0100T739)REMARK Ensure tension and frequency of pump ( read motor plate ) and supply network are same.Electric shock riskDANGERMake sure that float switch turns off pump, when at min.level of liquid.REMARKMake sure no obstacles stand in the way of float switch,during up/down swinging.REMARK5GB Overload ProtectionDRENOX® range pumps have a built-in thermal overload with automatic reset.Further protections are not required.DRENOX® range three phase pumps can be protected by using a magneto-thermic motor protector or a contactor with thermalrelay; in both cases they have to be rated conforming to nominal power showed on motor plate.Eventual electric float switch must be connected to auxiliary connector buckles. Rotation direction testing three phase pumpsWater head and delivery are terribly effected by wrong rotation of shaft of pump motor.Clock wise rotation is correct ( upside view of pump ).When starting the pump, motor will ungergo an anti-clock wise back-kick.In this case test is positive; on contrary case, please disconnect pump from network and inverse two phases.CONNECTIONS DIAGRAM:1) START ( green )2) RUN ( red )3) COMMON ( black )4) CAPACITOR5) SUPPLY CORD6) GROMMET7) PLUG8) YELLOW-GREEN9) WHITE10) LIGHT BLUE < LINE >11) BROWN < LINE >12) FLOAT SWITCH See Pict. 2A) Single phase manual pumpB) Single phase automatic pumpC) Three phase pumpSee diagrams Pict.2No maintenance is required when DRENOX® range pumps operate in normal conditions.Occasionally maintenance of liquid ends and replacement of impeller may be required. FAULT POSSIBLE CAUSE REMEDY1) No electric current supplying.2) Incorrect plugging in .3) Circuit-breaker come into operation.4) Impeller blocked.5) Motor or capacitor damaged.2) Verify presence of electric current supply andplug in.3) Reinforce circuit-breaker.Please call electrician in case circuit-breakercomes again into operation.4) Remove obstacle.5) Call dealer.PUMP DOES NOT DELIVER,MOTOR DOES NOT RUN.1) Filter obstructed.2) Non return valve blocked.PUMP DOES NOT DELIVER,MOTOR RUNS.PUMP DELIVERS REDUCEDWATER1) Filter partially obstructed .2) Delivery pipe partially obstructed.3) Impeller worn off.4) Anticlockwise rotation ( three phaseversion).1) Clean filter.2) Remove obstacles.3) Replace impeller.4) Inverse two phases.1) Clean filter.2) Clean or replace valve.INTERMITTENT WORKING(SINGLE PHASE VERSION)1) Solids obstruct impeller.2) Too warm liquid.3) Motor broken.1) Remove obstacles.3) Call dealer.
