1. INTRODUCTION

1.1 KMS MF Series KMS MF is designed for low/middle dosing of chemicals.

The pump has different working modes: Constant, Divide, Multiply, ppm, perc, mlq, batch, volt, mA.

KMS MF has got:

- STAND-BY input

- SEFL (flow sensor) input

- LEVEL input

- ALARM contact output.

Flow rate is determined by the stroke length and by the stroke speed. The stroke length is adjustable from 0 to
100% using the stroke length adjustment knob. However dosing accuracy is guarantee within an adjustment
range from 30% to 100%.

All control and setup parameters are available through a digital keyboard and they are displayed on a LCD backlit display.

✎

Note: some functions described into this manual may need accessories not included into the

pump packaging.

1.2 KMSA MF Series KMSA MF is the KMS MF version with self-venting pump head.

Self-venting pump head must be used when using chemicals that produce gas (i.e. hydrogen peroxide, ammonium,
sodium hypoclorite at particular conditions).

For connections ⎘ “Self-Venting pump head installation”.

1.3 KMS AC MF Series KMS AC MF is the KMS MF version with double supply: compressed air and power supply. Compressed air
without lubrifiant and/or condensed water. Air supply pressure range must be from 6 to 10 bar.

For connections ⎘ p. 5.

Pump can work in differents ways:

MODE WORKING MODES

CONSTANT

Pump doses at a constant rate set in “SPH” (strokes for hour), “SPM” (strokes for minute) or
“LPH” (litres per hour) parameters set during program session.

DIVIDE

External pulses from a water meter are divided by a value set during program session. The pump
doses with a rate determined by this parameter.

MULTIPLY

External pulses from a water meter are multiplied by a value set during program session. The
pump doses with a rate determined by this parameter.

PPM

Dosing rate is determined by pulses from a water meter on the base of set PPM, chemical
product concentration (%) and quantity for each single stroke set during program session.

PERC

Dosing rate is determined by pulses from a water meter on the base of set PERC (%), chemical
product concentration (%) and quantity for each single stroke set during program session.

MLQ

Dosing rate is determined by pulses from a water meter on the base of set MLQ (milliliters
per quintal), chemical product concentration (%) and quantity for each single stroke set during
program session.

BATCH Signal from an external contact starts the pump to dose the set quantity.

VOLT

Voltage from an external device drives the pump that doses proportionally using a minimum
and maximum of strokes for minute set during program session (0–10 VDC).

mA

Current from an external device drives the pump that doses proportionally using a minimum
and maximum of strokes for minute set during program session.

✎ In MULTIPLY, DIVIDE, PPM, PERC, MLQ working modes, the pump, connected to a pulse emitter water

meter, shows the instant flow.

4. BEFORE TO INSTALL WARNINGS

Pump’s installation and operativity is made in 4 main steps:

Pump’s installation

Hydraulic Installation (hoses, level probe, injection valve)

Electrical Installation (main power connection, SEFL installation, priming)

Programming the pump.

Before to start, please read carefully the following safety information.

Protective clothes

Wear always protective clothes as masks, gloves, safety glasses, ear
plugs or ear muffs and further security devices during ALL installation
procedure and while handling chemicals.

Installation location

Pump must be installed in a safety place and fixed to the table / wall to
avoid vibration problems!

Pump must be installed in a easy accessible place!

Pump must be installed in horizontal position!

Avoid water splashes and direct sun!

Hoses and Valves

Suction and delivery hoses must be installed in vertical position!
All hoses connections must be performed using only hands’ force!
No tongs required!

Delivery hose must be firmly fixed to avoid suddenly movements

that could damage near objects!

Suction hose must be shorter as possible and installed in vertical
position to avoid air bubbles suction!

Use only hoses compatibles with product to dose! See chemical
compatibility table. If dosing product is not listed please
consult full compatibility table or contact chemical’s manufacturer!

Feeder should be interlocked with a no-flow protection device to automatically shut-off
the pumps when there is no flow!

Adequate measures shall be taken to prevent cross connection of chemicals!

Chemical feeding must be stopped during backwash cycles and periods of noflow as these
conditions may introduce the potential for chemical overdosing. Not doing so may result
in elevated chemical concentrations and hazerdous gas introduction into the pool or spa.

7. ELECTRICAL INSTALLATION

All electrical connections must be performed by AUTHORIZED AND QUALIFIED personnel only.
Before to proceed, please, verify the following steps:

- verify that pump’s label values are compatible with main power supply.

- pump must be connected to a plant with a differential switch (0,03A

sensitivity) if there isn’t a good ground.

- to avoid damages to the pump do not install it in parallel with heavy

inductance load (for example: engines). A relay switch must be used. See
below picture.

P - Dosing Pump

R - Relay

I - Switch or safety device

E - Electrovalve or inductance load

A - Main Power

WARNING

IF EQUIPMENT IS NOT SUPPLIED WITH A PLUG:

a) a switch or circuit-breaker shall be included in the building installation

b) it shall be in close proximity to the equipment and within easy reach of the operator

c) it shall be marked as the disconnetting device for the equipment

WARNING

IF EQUIPMENT IS SUPPLIED WITH A PLUG:

If an appliance coupler or separable plug is used as the disconnecting device, it shall be readily identifiable

and easily reached by the operator. For single-phase portable equipment, a plug on a cord of length not

greater than 3m is considered to be easily reached.

17

Once verified previous steps proceed as follows:

- check that “BNC” of level probe has been connected as described in “Hydraulic

Installation” chapter.

- connect “BNC” and external signal to pump’s “INPUT” connectors.

-braided shield cable; +center conductor

This input may be used as follows:

- as pulse sender water meter or

- as startup contact for “BATCH” mode or

- as voltage input for “VOLT” mode or

- as current input for “mA” mode

- connect alarm and/or stand-by signal as described below fig (E):

- proceed to “SEFL” connection (Flow sensor is optional) as described in page 56.

To activate a working mode (Constant, Divide, Multiply, PPM, PERC, MLQ, Batch, Volt, mA) select the required mode and
confirm it using “E” key.

Turning on and off the pump

“ESC” key has a double function. It can be used to discard all changes made into setup mode or to turn on/off the pump. To

turn on/off the pump press and keep pressed this key while in main screen (fig.3). The pumps will show:

To return into operating mode press “ESC” key.

Alarm output logical working.

The pump has an “Alarm” output that changes its status (from N.O. to N.C. or viceversa) when a signal is received from “LEVEL”
and/or “SEFL” and/or “STAND-BY”. To set this alarm refer to related chapter.

Full menu / Short Menu mode

When entering into SETUP display shows access mode menu:

If this is the first time into SETUP menu then the pump will automatically set itself into “FULL” menu mode as shown in fig. A.
Just press “E” key to confirm. This mode will show all pump functions and working modes.

Next time the SETUP menu will be reached it will possible to operate with “SHORT” menu configuration to change only selected

the pump will show the “Delay” (pump’s activation delay) as shown fig.2:

Press any key to skip the “Delay”. Pump will show “Srokes” (actual strokes) as shown in fig.3:

In any working mode, if a SEFL is installed and enabled (see SEFL Setup procedure), the display will show the icon (asterisk
as in fig. 4):

- if SEFL works correctly, the asterisk blinks to any pulses given by the solenoid;

- if the asterisk does not appear, there is an anomaly (i.e.: hoses and/or valves are obstructed, SEFL in not connected, etc.).

Press and keep pressed the “RIGHT” key to enter into priming mode. Pump will go for 30 seconds into priming mode as shown
in fig.5.

When the chemical begins to flow out from the outgassing hose then completely close the outgassing knob (except for self­venting pump heads). This ends the priming procedure. If countdown for priming is not yet ended press “ESC” key.

Now the pump is operative. Proceed to setup and programming.
