OPERATING CYCLE

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.

It is recommended that the use of the pump be according to normative safety standards

and also as per the precautions listed below.

The pump can be mounted in any position. Fix the pump utilizing suitable diameter

screws corresponding to the holes.

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.

The pump can operate on a continuous cycle with the following conditions:

It is possible to operate at higher pressures/ampere draw if On/Off cycles are used. This will

allow the motor to cool down to the indicated temperatures.

Long pipelines and / or reduced diameters, bottlenecks and dispensing guns, affect the

operating pressure (which is not automatically limited): in these cases, check that the

pressure and the electrical draw do not exceed the values of the attached diagrams.

pressures not exceeding 50% of the maximum pressure indicated in the technical

data (not for OIL type)

temperature of the motor below 60/70°C.

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.

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.

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 and without 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).

Utilize tubes and connection pieces that are resistant to the fluid types handled and

avoid any possible environmental dispersion.

In this case frequent cleaning and maintenance of the filter is

advisable. The standard filter withstands a maximum positive pressure of 0.5 bar.

The electrical installation of the pump must include a protection fuse which is suitably rated

as indicated on the motor label.

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 potential risk of motor overheating.

WARRANTY EXPIRES IF NO FUSE IS UTILIZED

WARNING: DUE TO THE EMI FILTER THE PUMP IS NOT SUITABLE FOR

SWITCHING APPLICATIONS

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.

TROUBLESHOOTING

WHY THE PUMP WILL NOT PRIME ITSELF?

CHECK POINTS IF THE PUMP HAS STOPPED OR WILL NOT START

GOOD PRACTICES ENSURING A WELL FUNCTIONING PUMP

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.

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 aqua-stop)

Presence of liquid loops in the outlet tube

ØDirty bypass valve (VP45 series)

If it is expected that the pump will not be used for a period of at least 30 days, especially in the

case of usage with water, it is advisable to run fresh water 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.

ENVIRONMENTAL DISPOSAL

WARRANTY

PACKAGING ENVIRONMENTAL DISPOSAL

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.

ØReplace the rubber impeller every season or every 500 hours (for UP1 series).

Temperature of body and motor frame is within 60°C and 70°C (140 °F - 158 °F);

Amp-draw within the limits indicated in the diagrams.

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.

Do not dispose of pumps into household waste: pumps that are no longer usable, must

be collected separately and and disposed of in an enviromentally correct manner.

The user is invited to effect a proper waste separation, in order to facilitate the recycling

of the materials of which the packing is composed.

1) The Warranty period is 2 years from date of purchase on production of the

appropriate sales invoice.

2) Should the original sales invoice not be available, then the 2 year warranty

period will be valid from production date.

3) The Warranty becomes null and void in the case of incorrect utilization or

disregard of the instructions contained herein.

4) The Warranty only covers original production defects.

5) The Warranty does not cover any related installation costs involved.

6) Transport costs are refundable only in the case where warranty has been duly

accepted by Marco Spa and they will be limited to the actual shipment costs

between Marco Spa warehouse and the client's delivery address.

7) No credit notes or replacement items will be issued prior to the receipt and

proper testing of any Marco goods that are deemed faulty.
