• Keep this manual in a safe place, so that it will always be available for further consultation.
• The pump complies with EEC directives No.89/336 regarding “electromagnetic compatibility” and No.73/23 regarding “low voltages”, as also the subsequent modification No.93/68.
• The pump has been constructed in accordance with best practice. Both its life and it electrical and mechanical reliability will be enhanced if it is correctly used and subjected to regular maintenance.
• WARNING: Any intervention or repair to the internal parts of the pump must be carried out by qualified and authorized personnel. The manufacturers decline all responsibility for the consequences of failure to respect this rule.
• GUARANTEE: 2 years (the normal wearing parts are excluded, i.e.: valves, nipples, tube nuts, tubing, filter and injection valve). Improper use of the equipment invalidates the above guarantee. The guarantee is exactor or authorized distributors.

Shipping and transporting the pump

The pump should always be moved in a vertical (and never in a horizontal) position. No matter what the means of transport employed, delivery of the pump, even when free to the purchaser’s or the addressee’s domicile, is always at the purchaser’s risk. Claims for any missing materials must be made within 10 (ten) days of arrival, while claims for defective materials will be considered up to the 30th (thirtieth) day following receipt. Return of pumps or other materials to us or the authorized distributor must be agreed beforehand with the responsible personnel.

Proper use o f the pump
The pump should be used only for the purpose for which it has been expressly designed, namely the dosing of liquid additives. Any different use is to be considered improper and therefore dangerous. The pump should not therefore be used for applications that were not allowed for in its design. In case of doubt, please contact our offices for further information about the characteristics of the pump and its proper use. The manufactures cannot be held responsible for damage deriving from improper, erroneous or unreasonable use of the pump.

Risks

• After unpacking the pump, make sure it is completely sound. In case of doubt, do not use the pump and contact qualified personnel. The packing materials (especially bags made of plastics, polystyrene, etc.) should be kept out of the reach of children: they constitute potential sources of danger.
• Before you connect the pump, make sure that the voltage ratings, etc., correspond to your particular power supply. You will find these values on the rating plate attached to the pump.
• The electrical installation to which the pump is connected must comply with the standards and good practice rule in force in the country under consideration.
• Use of electrical equipment always implies observance of some basic rules: In particular:
  • do not touch the equipment with wet or damp hands or feet;
  •  do not operate the pump with bare feet (Example: swimming pool equipment);
  • do not leave the equipment exposed to the action of the atmospheric agents;
  • do not allow the pump to be used by children or unskilled individuals without supervision;
• In case of breakdown or improper functioning of the pump, switch off, but do not touch. Contact our technical assistance for any necessary repairs and insist on the use of original spares. Failure to respect this condition could render the pump unsafe for use.
• When you decide to make no further use of an installed pump, make sure to disconnect it from the power supply.

Before carrying out any service on the item, check:

• Disconnect the pins from the mains or by means of a two poles switch with 3 mm minimum distance between the contacts.
• Relieve all the pressure from the peristaltic pump and injection tube.
• Drain or flush all dosing liquid from the peristaltic.

In case of any losses in the hydraulic pump (rupture of the injection valve, filter, pipes), you have to stop operation of the pump depressurize the discharge pipe and then proceed with the maintenance using appropriate security measures (gloves, goggles, overalls, etc..). Dosaggio di liquidi nocivi e/o tossici.

Toxic and/ or dangerous liquid dosage
To avoid risk from contact with the hazardous liquids or toxic fumes, always adhere to the notes in this instruction manual:

• Follow the instructions of the dosing liquid manufacturer.
• Check the hydraulic part of the pump and use it only if it is in perfect condition.
• Use only the correct materials for the tubing, valves and seals to suit the liquid to be dosed; where possible shield the tubing with PVC conduit.
• Before disconnecting the metering pump, make sure to flush out and neutralize the pump head with the proper reagent liquid.

Assembly

All metering pumps are normally supplied fully assembled. For greater clarity, please consult the exploded view of the pump appended at the end of the manual, which shows all the pump details and a complete overview of all the pump components. These drawings are in any case quite indispensable whenever defective parts have to be re-ordered. For the same purpose, the appendix also contains other drawings showing the hydraulic parts (pump head and valves).

Dismantlement

• Proceed as follows before you dismantle the pump or before performing any other operation on it:
  • Disconnect the pins from the mains or by means of a two poles switch with 3 mm minimum distance between the contacts.
  • Relieve all the pressure from the peristaltic pump and injection tube.
  • Drain or flush all dosing liquid from the peristaltic.
• This operation calls for special attention, and you should therefore consult the drawings in Appendix and Chapter “RISKS” before you commence work.

PERISTALTIC PUMP Racer SERENITY SERIES

Operating principle
Peristalsis is a wave of automatic contractions propelling contents along channel or tube, this led to a peristaltic action. By mechanical simulation of biological peristalsis rollers crush tube walls together to form a seal while roller moves along the tube, then the previously compressed tube regains original form and sucks fluid into the formed vacuum. The fluid will follow the roller until tube is not compressed any more, then to avoid a flow back a second roller compress the tube, pushing the fluid out of the pump and repeating the suction action while the pump continues to operate the rollers which are fitted on a special rotor create suction lift and outlet pressure.

Common features

• The products are manufactured according regulation
• Plastic housing in PP
• Level control (supplied with probe)

Standard power supply (fluctuations not to exceed ±10%): 230 V a.c. 50 Hz single phase.

Liquid ends materials

• Hose: Santoprene®
• Filter: Standard: Polypropylene
• Suction hose: PVC Cristal®
• Discharge hose: Polyethylene

INSTALLATION

• Install the pump in a dry place and well away from sources of heat and, in any case, at environmental temperatures not exceeding 40°C. The minimum operating temperature depends on the liquid to be pumped, bearing in mind that it must always remain in a liquid state.
• Carefully observe the regulations in force in the various countries as regards electrical installations (Fig.2). When the supply cable is devoid of a plug, the equipment should be connected to the supply mains by means of a single-pole circuit breaker having a minimum distance of 3 mm between the contacts. Before accessing any of the electrical parts, make sure that all the supply circuits are open.
• You can connect auxiliary inputs 1 and 2 of the pump RACER SERENITY (1) the circulation pump (2). The dosage is enabled only when the circulation pump is in action. This feature must be enabled in the programming menu.
• Locate the pump as shown in fig. 3 bearing in mind that it may be installed either below or above the level of the liquid to be dosed, though the level difference should not exceed 2 meters. In case of liquids that generate aggressive vapours, do not install the pump above the storage tank unless the latter is hermetically sealed.
• Slide the hoses over the nipples, pushing them right home and then fix them with appropriate tube nuts. Try to keep both the suction and discharge hose as straight as possible, avoiding all unnecessary bends. Select the most appropriate injection point on a pipe of the plant to be treated and there fit a 3/8″ female steel gas thread connector (similar to        BSPm). This connector is not supplied with the pump. Screw the injection valve to the gas connector, inserting a gasket tape as Teflon. Then connect the discharge hose to the conical connector on the injection valve and fix it with the supplied tube nut. The injection valve also acts as no return valve by means of a cylinder sleeve.

Racer SERENITY PH – RX

Features of Racer SERENITY

• Racer SERENITY is a friendly user equipment, made by a peristaltic pump and an electronic controller able to measure and settle the chemical-physical values of a swimming pool, like the pH and the ORP (mV) values. The pump operate in proportional mode.
  • pH factory defaults : Setpoint= 7,2 pH; intervention: ACID
  • RX factory defaults : Setpoint= 700mV; intervention: OXIDANT

Controls

1. Button to increase the value
2. Button to decrease the value
3. Button MENU/ESC
4. Button to CAL/OK
5. Button to set the stpoint7 segments display
6. Digital display

Alarm measure LOW / HIGH
If the value of the measure is below 3.5 pH or higher of 11 pH, the display will show a message of error low or high concentration of the acid in the swimming pool. For the REDOX the only type of dosification is only oxidant direction, so it is possible only a low error for values of mV below 100.

• Stand- by
  Press in the same time arrow up (1) and arrow down (2), (fig. 4).

• Priming
  With the pump in stand-by at the same time press MENU/ESC (3) and CAL/OK (4) (FIG.4).

Configuration procedure BASIC

PUSH the MENU button for 5 seconds to enter into BASIC setup menu of the operating parameters.

EXPERT Configuration procedure
Simultaneously press the buttons UP ARROW (1) and the button MENU/ESC (3) for 5 secs to enter the EXPERT menu configuration of all the parameters.

• LANGUAGE
  It is possible to choose on language between the following: ENGLISH, DEUTSCH, NEDERLANDS, PORTUGUES, ESPANOL, ITALIANO, FRANCAIS.

• TYPE OF INSTRUMENT
  RACER SERENITY are supplied as pH or Redox mode however it is possible to change to either pH or Redox..

• DOSAGE TYPE
  pH mode can be ACID (pH -) or ALKALINE (pH +), while for the REDOX instrument it is OXIDANT only

• AUX INPUT
  It is possible to enable a 230V input coming from a recirculation pump. Using Terminals 1 and 2, and enabling the AUX INPUT, will enable an additional relay output of 230 Vac (terminals 4 and 5).

• PUMP FLOW RATE
  It is possible to choose change flowrate between 1.5 l/h and 3 l/h. This change will change the cycle time of the motor (300 or 450 seconds).

• PUMP ACTIVATE TIME

  • In this menu, we are able to modify the time proportionality of the pump. This is achieved by defining the number of seconds of activation of the peristaltic in proportion with the signal coming from the ph/Rx electrode.
  • The operating activation time for pH is 3 to 30 seconds for each 0.1 pH.
  • The operating activation time for RX is 1 to 15 seconds per mV.

Example for pH

• Setpoint: 7,2 pH
• Electrode measure: 8,00 pH
• ACTIVATION TIME: 20 sec.
• FLOW RATE OF THE PUMP 1,5 l/h (motor cycle time 300 sec.)
• T on (dosage time) = (8 – 7,2) = 0,8 = (8 decimal pH of increase); 8 x 20 = 160 secondi
• T off (pause time) = 300 – 160 = 140 secondi

| Example for Redox

• Setpoint: 700 mV
• Electrode measure: 680 mV
• ACTIVATION TIME: 9 sec.
• FLOW RATE OF THE PUMP 3,00 l/h (motor cycle time 450 sec.)
• T on (dosage time) = (700 – 680) x 9 = 180 secondi T off (pause time) = 450 – 180 = 270 secondi

---|---

• OVERDOSE ALARM
  

  • It is possible to set an overdose alarm, relating to the number of litres dosed during 4 hours of operation. It is also possible to deactivate the alarm for 24h or 48h, in the next menu called OFF ALARM
  • The possible choices are: Active Alarm (immediately), Alarm Off 24h, Alarm off 48h.
  • This delay is automatically disabled if the instrument is powered off.

• N° CALIBRATION POINT
  For pH it is possible to choose between one or two calibration points. For REDOX instrument, the calibration point is always 1, signal point).

• MEASURE OFFSET
  The instrument allows the movement of the OFFSET with maximum +/- 0.4 pH (or +/- 30 mV in the case of redox). By performing the calibration, it will reset the displacement offset.

• DELA Y START
  The instrument has the ability to adjust the delay time from start up to allow correct control measurement. This feature is present only in the REDOX mode.

• RESET
  Allows the operator to return the instrument to the original configuration (factory configuration) performing a TOTAL RESET of all parameters.

• Setpoint setting
  Press the SET click for after 3 seconds until the screen does not appear in “SET POINT” To change the value in the same time click the button to decrease or increase the value. Note that the pH-value can be set is from 3,5 to 11 and the ORP from 300 mV to 900 mV

• Calibration
  Press for 5 seconds the CAL/OK bottun. The Calibration menu appears on the screen. You can look down the procedure of the calibration for pH, please note that if calibration is for the redox measure there will be only one point calibration with the buffer solution 650 mV. After calibration on the display will appear a life persentage of the probe, down 25% there will be a calibration error, this means that the probe has to be replaced. PLEASE NOTE: Standard buffer solution for the pH measure are pH 7 and pH 9, there will be an calibration error if a buffer solution 4 pH is used.

NOTE: After calibrating the electrode with the solution pH 9 the instrument could show the alarm concentration error, this alarm will disappear when the electrode is put into operation.

Level alarm
If the level probe switch is connected to the controller unit, the pump will be stopped and an alarm message will applier on the display,“TANK LEVEL LOW”, if the chemical is finish in the tank.

SERVICE CONNECTOR WIRING DIAGRAMS AND FUNCTIONS

In figure 5 is shown the scheme of the service connector for the connection of the various services. To the service connector is accessed by removing the protective cover as shown in fig. 2.

• Connectors 1-2 (PMP)= Connection for the recirculation pump. Input at 230V. (Fig.2).
• Connectors 4-5 (AUX)= Output relay. This output is powered at 230V and it work in proportional mode by time like the peristaltic pump.
• Connectors 7-8 (ALM)= Alarm relay. Free contact
• Connectors 10-11 (LEV)= Level probe connexion
• Connectors 12-13-14-15-16-17-18= It is not used

MAINTENANCE

• Check from time to time the chemical solution into the tank to avoid peristaltic pump to dry running. In case this should happen no damages will occur to the pump. The level control sensor provided as a standard accessory will stop the pump in case of chemical low level in the tank, anyway a systematic check to avoid lack of chemical in the system is advisable.
• For finding eventual tears and wear, a three months check to the pump hose is recommended as well as a periodical cleaning for foot filter and injection valve (see next point). Screws and seals status check is also advisable each 3 months time or at the end of the season. The use of very aggressive or solid suspended chemicals require more frequent controls.
• As above mentioned, the wetted parts are to be maintained from time to time using the most appropriate cleaning reagent. Considering the large number of chemicals available in the market a general advice is not possible.

That said, we can suggest in the case the pump works with sodium hypochlorite:

1. Make sure that the pump is deactivated electrically (both polarities) by detaching the conductors from the contact points of the mains through an omni polar switch with a minimum distance between the contacts of 3mm.
2. Disconnect the delivery pipe from the connector
3. Remove the suction pipe (with filter) from the tank and dip it into clean water
4. Start the peristaltic pump and have it work with water for 5-10 minutes
5. With the pump disconnected dip the filter into a solution of 10% hydrochloric acid and wait for the acid to finish its cleaning action
6. Start again the pump making it work with 10% hydrochloric acid for 5 minutes, creating a closed circuit with suction and discharge immersed in the same container
7. Repeat the operation with water
8. Connect again the peristaltic pump to the system

TROUBLE-SHOOTING COMMON TO RACER SERENITY

Mechanical faults
As the system is quite robust there are no apparent mechanical problems. Occasionally there might be a loss of liquid from the nipple because the tube nut has loosened, or more simply the peristaltic tube has broken. In this case they have to be replaced. After repair, the peristaltic pump will need to be cleaned of additive residues which can damage the pump casing.

PERISTALTIC TURNING BUT THE ADDITIVE IS NOT INJECTED

1. Check the integrity of peristaltic tube. Should the tube be swollen, check tube material against our chemical resistance compatibility chart.
2. Check clogging of the filter.
3. Check clogging of the injection valve.

Electrical faults

• THE PUMP DOES NOT MEASURE CORRECTLY
  • Check the calibration of controller
  • Check the efficacy of the electrode
• THE PERISTALTIC PUMP FAIL TO DOSE
  • Make sure the “Setpoint” has been correctly set
  • Make sure the “ACID/ALK” jumper is in the right position, i.e. that it concords with the required dosing.

IN CASE THE ADDITIVE LEVEL IS BELOW THE LEVEL PROBE AND LEVEL ALARM IS STILL OFF

• Check the level switch connection, short circuit poles connector (Chapter SERVICE CONNECTOR WIRING DIAGRAMS AND FUNCTIONS) in case the alarm is on, replace the switch; if the alarm is off, contact Manufacturer, Customer Service, Dealer or Distributor.
• Attention: when removing the peristaltic pump from the plant, use great care in detaching the delivery hose from the connector nipple, because it could contain some residual additive.
