1.0 - HINTS AND WARNINGS Please read the warning notices given in this section very carefully, because they provide important information regarding safety in installation, use and maintenance of the pump. • Keep this manual in a safe place, so that it will always be available for further consultation. •...
1.5 - 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 instruc- tion 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. •...

The pump doses in proportional way to the power signal Operating range: 0 – 20 mA pulses per minute 0-120 pump pulses per minute Minimum and maximum cutoff points are adjustable: Stop/Continue dosing The pump can dose directly in PPM. User can set the following parameters: Water meter liter/contacts 0.1, 0.25, 0.5, 1, 2.5, 5, 10, 25, 50, 100, 250, 500, 1000.
3.0 - INSTALLATION a. - Install the pump in a dry place and well away from sources of heat and, in any case, at environmental tem- peratures 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.
Fig. 8 Whenever the pump is dismantled from the pipework, you will be well advised to replace the caps on the connectors to avoid residual liquid being spilled. Before attaching the delivery hose to the plant, prime the metering pump by going through the sequence shown in Fig. 8. Before finalizing the installation of the dis- charge hose, make sure that the pump strokes will not cause it to move and bump into rigid bodies.
4.0 - MAINTENANCE 1. Periodically check the chemical tank level to avoid the pump operating without liquid. This would not dam- age the pump, but may damage the process plant due to lack of chemicals. 2. Check the pump operating condition at least every 6 months, pump head position, screws, bolts and seals; check more frequently where aggressive chemicals are pumped, especially: - pulse and power L.E.D.;...

8.0 DESCRIPTION OF OPERATING MODE MANUAL In this mode, the pump operates with its flow rate manually controlled the keypad. Stroke rate can be set in three ways: • Pulses per minute (this is common for normal metering pump operations). •...
• The volume per pump pulse, from 0.01 to 20.00 cc. Our pumps have cc/pulse ratings, but for greater accuracy due difference in liquid properties, the user would need to calibrate the volume of each pump pulse at site, using a measuring cylinder. •...
9.0 - TROUBLE-SHOOTING COMMON TO DLX - DLXB MF SERIES 9.1 - 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 discharge tubing-has broken. Very rarely there may be losses caused by the breakage of the membrane, or by the membrane seals in which case they have to be replaced by disassembling the four screws of the pump head fig.
THE PUMP JUST SWITCHED ON GIVE TWO OR THREE INJECTION AND THEN STOP Check the Remote Control Menù and the Alarm Menù for proper setting. If setting are correct, reset the pump follow- ing the procedure described in chapter 6.3. IN CASE THE ADDITIVE LEVEL IS BELOW THE LEVEL PROBE AND THE LEVEL ALARM IS STILL OFF Check the level switch connection, short circuit poles connector (Section 3.2 pos.
