MARCO 164 740 15 Self Priming Electric Pump Instructions

When starting the pump, or when emptying the tank, slightly open the small valve, in order to let air out and facilitate the priming. As soon as the pump is operating, close the small valve. On the outlet side it is advisable to use at least a short section of 1 m length flexible tubing

ELECTRONIC PRESSURE SENSOR WORKING DIRECTIONS

The electronic pressure sensor, through the use of a microprocessor, controls the pump’s speed to obtain the needed flow rate, with the following advantages:

• Noise reduction during operation
• The optimization of current consumption
• A strong reduction of electrical noise, thanks to the slow speed ramp up and ramp down of the motor.
• A longer life for the whole system, thanks to less wear of pump parts compared to conventional mechanical pressure switches.

The pressure sensor system is equipped with two LEDs: one blue and one multicolored (red, green, and yellow).

During normal operation, the blue LEDwill:

• Turn on if there’s liquid in the hoses.
• Turn off when there’s no liquid in the hoses.
• Flash when in priming mode. The first time it senses liquid it keeps flashing for 10 seconds to make sure that the liquid is being pumped correctly and continuously.

If the pump goes more than five times from “priming” to “no liquid” (blue led off) the circuit turns everything off anyway, to protect the motor and the gears from running without liquid.

The multicolored LED signals:

• With solid yellow LED, that the pressure in the hoses is not the required pressure, but the pump is trying to reach it.

• With solid green LED, that the pump has reached the target pressure, there is still liquid demand, but the pump’s speed won’t be changed because the flow rate is constant.

• With flashing green LED, the pump has reached the target pressure and there is no liquid demand, it’s in stand-by with the motor off.

• With solid or slowly flashing red LED, the motor has been short circuited, something may have blocked the gears or there could be a problem in the connection between the pump and circuit. The red LED flashes for 30 seconds, after which the pump is re-fed up to a maximum of 3 attempts.
  On the fourth attempt, the LED remains solid red, the pump is off and should be checked for possible permanent damage.
  To reset this warning you need to reboot the circuit or press the Reset button on the control panel, if present.

• With fast flashing red LED, the pump is being overloaded (due to viscous liquids or gears overheating). While the pump is running, the speed is reduced to keep the current up to the nominal value for 30 seconds, period after which the circuit tries to release again the motor to its normal operating speed.
  If an overload happens again, the circuit tries three time to lower the speed and it turns the pump off. Please check that the liquid being pumped is correct forthe chosen pump and that the gears move freely without problems.
  To reset this warning you have to reboot the circuit or press the Reset button on the control panel, if present.

There are two warnings that use both LEDs:

• Red and blue LED that blink alternatively, signal that the pump has run without liquid for the time listed in table N.1 and the motor has been stopped for this reason. To reset this warning you have to reboot the circuit or press the Reset button on the control panel, if present.
• Yellow and blue LED that blink togetherindicate that the power supply is providing the wrong voltage. Please check to have the correct wire section for the power supply and a charged battery, if present.
• Steady red and blinking Blue indicate that the pump has run for more than the time listed in table N.1 at very low speeds and that the motor has been stopped to prevent overheating.To reset this warning you have to reboot the circuit or press the Reset button on the control panel, if present.

Warning

An expansion tank of at least ½ literis necessary in the case of short,rigid pipes or in the presence of solenoid valves, to avoid overpressures during the closing phase caused by a water hammer effect which could damage the pressure sensor.

The presence of a few meters of flexible pipe inside the system can prevent the installation of the expansion tank.

Additional pressure regulators or non-return valves on the pump delivery may interfere with the correct operation of the electronic pressure sensor.

AMBIENT CONDITIONS

TEMPERATURE: min.-10°C 14°F-max.60°C 140°F RELATIVE HUMIDITY: max. 90 %

WARNING: the above indicated temperature ranges are applicable to all components of the pump and these limits must be respected in order to avoid any possible damage or malfunctioning

OPERATING CYCLE

Under conditions of high operating pressures the pump can be subjected to elevated stresses and overheating and therefore should not be used for prolonged periods under such conditions

TRANSPORTATION AND HANDLING

Due to limited weight and dimensions the pump does not require the use of any special handling or lifting equipment. When handling manually, normal personal protective gear should be worn (safety shoes with toe piece, etc.). The pump is carefully packed prior to shipment. Upon receiving, the packaging should be inspected for damages and the pump stored in a dry area.

INSTALLATION

It is recommended that the use of the pump be according to normative safety standards and also as per the precautions listed below.

PRELIMINARY CHECKS

Check that there has been no damage to the pump during transportation or storage. Both inlet and outlet ports should be carefully cleaned removing possible dust or residual packaging material. Verify that the available electrical power supply corresponds to the specification requirements.

POSITIONING

The pump can be mounted in any position. Fix the pump utilizing suitable diameter screws corresponding to the holes

To ensure the correct directional flow of the fluid as indicated by the arrow on the top plate, it is necessary to connect the positive pole (+) of the battery supply to the red wire on the motor end-cap and the negative pole (-) to the black wire. Electrical connections must be made using adequate terminal blocks and connectors ensuring a tight fitment of the electrical cables. Bad wiring can cause power losses and/or overheating of the cabling itself

WARNING: it is the responsibility of the installation technician to ensure a correctly designed circuit installation fitted according to regulations. Environmental risks must be taken into account with the installation.

Tubing Connections

• Prior to making any tube/hose connections, check that the inlet ports have no end caps;
• Do not position the pump at a excessive height with respect to the minimum level of the fluid to be transferred. Damage may occur if this height is exceeded as the pump may not draw fluid. Make sure that the outlet tube is empty andwithout chokes;
• Avoid choking the inlet or outlet tubes so that efficiency is optimized.
• The use of an inlet filter is recommended especially with fluids containing impurities (mesh ASTM no. 35).  In this case frequent cleaning and maintenance of the filter is advisable. The standard filter withstands a maximum positive pressure of 0.5 bar.
• Utilize tubes and connection pieces that are resistant to the fluid types handled and avoid any possible environmental dispersion.

Electrical Connection

The electrical installation of the pump must include a protection fuse which is suitably rated as indicated on the motorl abel

WARRANTY EXPIRES IF NO FUSE IS UTILIZED

Always mount the anti vibration rubber fittings supplied with the pump kit. Their usage ensures a consistent reduction in noise and vibration levels. Electrical cabling size should depend on the distance between pump and battery/power supply (see Tab.1 EN). The use of undersized cabling can cause overheating of the electrical wiring and subsequent fire hazard. There will also be a voltage drop at the motor terminals with a consequent reduction in efficiency. The flow rate value indicated on the motor label is obtained with internal tube diameter indicated on Tab.1 EN. Tubes with inferior diameters will cause an increase in current with potentialrisk of motor overheating.

TROUBLESHOOTING

CHECK POINTS IF THE PUMP HAS STOPPED OR WILL NOT START

• Check the effectiveness of the battery power supply (voltage activity);
• Check if the fuse has blown;
• Check for any foreign matter present in the pump body. To do this, disconnect the power supply and unscrew the four fixing screws, remove the front cover plate and inspect the chamber. Replace the cover plate in the same initial position after inspection;
• Avoid running the pump dry for more than a few minutes. Pumps found defective that have run dry in the absence of fluid are not covered by warranty;
• The average life span of the motor commutator brushes is approximately 2500 hours under normal operating conditions. Stoppages are possible due to brush wear and tear after such a time period.

WHY THE PUMP WILL NOT PRIME ITSELF?

• The pump is fitted at an excessive height above the fluid level
• The pump has run dry for too long a period
• Long periods of inactivity. In this case it is advisable to add liquid directly into the chamber before start-up
• Air leak at the suction pipe due to the following reasons, possible cuts in the pipe, inadequate hose clamps, malfunctioning of the filter due to defective/worn seals or filter clogged
• Air leak at the front plate cover due to the following reasons, loose fixing screws, poor effectiveness of the seal
• Faulty electrical cable connections
• Presence of obstructions or restrictions in the suction or delivery pipes or the use of special devices (eg. automatic spray pistol or Aquastop)
• Presence of liquid loops in the outlet tube
• Dirty bypass valve (VP45 series)

GOOD PRACTICES ENSURING A WELL FUNCTIONING PUMP

If it is expected that the pump will not be used for a period of at least 30 days, it is advisable to run liquid through it and to then loosen the front plate screws. Upon re-use, run the pump briefly (a few seconds) and tighten the screws again. Check under conditions of maximum operating pressure that the motor current value is within the motor label specifications

NORMAL MAINTENANCE

• Check frequently and keep the inlet filter clean.
• Check every month the chamber and keep clean from any foreign matter.
• Check every month that electrical wiring is in good condition.
• Replace the rubber impeller every season or every 500 hours (for UP1 series).

INDICATORS THAT THE PUMP IS FUNCTIONING CORRECTLY

• Temperature of body and motor frame is within 60°C and 70°C (140 °F – 158 °F);
• Regular flow and constant noise levels;
• Amp-draw within the limits indicated in the diagrams.

TO OPEN THE PUMP

• It is recommended that a specialized service technician be consulted for any repair work or the replacement of worn out internal components, exclusively with original spare parts; during the warranty period, only by authorized Marco S.p.A. personnel, failing which the warranty will expire.
