SAFETY INFORMATIONS

Read the safety information before installing the water purifier

2.1 WARNING LABELS

Before reading the manual, please get familiarized with the following icons used in this manual.

Electric Shock

Warnings

2.2 SAFETY INSTRUCTIONS

To ensure the product SECURITY and RELIABILITY, all repairing must be realized with spare parts

available with our after-sales service. If the power cable is damaged, it must be replaced.

Unplug the water purifier power plug. Don’t pull on the wire.

Before all maintenance on the water purifier, turn off the power supply switch and

unplug the power plug.

Use exclusively tap water to supply the water purifier.

- MAXIMUM NETWORK PRESSURE = 6 BARS

- Maximum supply water temperature = 38 °C.

This water purifier needs a main tension 230 volts ~ / 50 Hz.

Don’t connect too much instruments on the same plug in order to not risk fire

or electric shock.

INTRODUCTION TO THE SYSTEM

3.1 INTRODUCTION

The DiaSys water purifier « O MINI » is a purified water production system allowing two water

treatment leading-edge technologies:

The BI-REVERSE OSMOSIS, which is currently the most effective and elaborated - membranous

separation process,

The demineralization principle by IONS EXCHANGERS RESINS.

These two associated technologies allow getting water with excellent quality regarding

physical composition, chemical composition (mineral and organic) and micro organic

population.

3.3 OVERVIEW OF THE SYSTEM (BACK VIEW)

3.4 GENERAL DESCRIPTION

The "o mini" osmosis system is a water treatment system that includes a series of

prefiltration cartridges for the network water: Sediment filter 5 μm + Block carbon filter.

Once this water is treated, it is then injected via a booster pump into the reverse osmosis

membrane.

The water obtained is thus discharged of 90% of its organic and inorganic compounds.

In order to complete the complete treatment, this water is then injected into an ion exchange

resin container and then filtered by a 5 μm post-treatment filter.

The electromechanical assembly is managed by an electronic control unit.

3.5 DESCRIPTION OF THE CONTROL UNIT

PUMP indicator turned on

Pump functioning: means the water purifier is either producing or

rinsing.

FLUSH indicator turned on

The water purifier makes an automatic rinsing cycle of the reverse

osmosis membrane; a rinsing (of around 2 min) happens:

- following to the instrument starting,

- following a frequency of around 6 hours,

- following a pressure on the MANUAL button.

SOURCE indicator turned on

Lack of flow or pressure on water supply.

FULL indicator turned on

Full storage tank.

POWER indicator turned on

water purifier under tension; this indicator is switched on

permanently, whatever the other indicators states are.

MANUAL push button

Press this button makes starting a forced rinsing of the membrane

during 2 min.

INSTALLING THE WATER PURIFIER

5.1 INSTALLATIONS CONDITIONS

Water inlet (2 to 5 bars) equipped with a turn hand valve or a male exit tap of 15/21 or 20/27.

Protected electric input (230 V ~, 50 Hz + EARTH).

Drain

5.2 CONNECTIONS

Connect to tap water inlet by

using « male simple union » –

Integrate an « isolation hand

valve »

Purified water outlet to be

connected via a tubing to an

"isolation valve" allowing water

to be drawn for the analyzer

To be connected to the storage

tank

Drain of the osmosis unit to be

connected directly to the

sewer (to avoid to damage the

system, must be always open

; do not connect a valve )

Connect to tape water inlet by

using « male simple union » –

Integrate an « isolation gate »

5.3 INSTALLATION OF THE WATER PURIFIER MEMBRANE

1. Remove the membrane holder out of its two plastic stirrups . (Figure 1)

2. Disconnect the water inlet pipe from the membrane holder by disconnecting the quick fit

coupling. (Figure 2)

3. Unscrew (by turning to the right) the high streaked part ("big cap") of the membrane holder.

4. Once the membrane door is opened. Insert the new membrane (Figure 3), peripheral seal at

the top, to the complete stop: the end of the collecting tube must be closed to the top of the

membrane holder. (Figure 4)

Figure 1 Figure 2

Figure 3 Figure 4

5. Check that the O-ring is well-positioned at the bottom of the retaining wall of the membrane

holder (see the drawing).

6. Unscrew (by turning to the right) the high streaked part ("big cap") of the membrane holder.

7. Clip the membrane on its stirrups.

SYSTEM START UP

1. Connect the water purifier hydraulically then electrically.

2. Check all hydraulic connections.

3. Close the storage tank valve.

4. Open the water purifier exit hand valve.

5. Open the city water supply valve.

6. Electrically switch on the water purifier.

7. The control unit goes through the following phases:

1 /

8. Wait (a few minutes) for purified water to drain from the water purifier exit hand valve, then

let about 20 liters flow.

9. Then carry out a conductivity. The value obtained must be 0 to 0.1 μS / cm. Then close the

water purifier exit hand valve.

Open the storage tank valve and wait for its full refill: "Full" indicator lit in green

The control unit goes through the following phase:

The water purifier is then operational

The power indicator indicates that the osmosis

unit is energized.

The pump indicator indicates that the pump is

running.

The flush indicator indicates that the system is in

the rinse phase of membrane.

When the flush light goes off the system enters its

production phase.
