Terminology:

The following technical terms are used in these instructions:

Permeate: Demineralised water produced by the RO-unit which is fed into the integrated

storage tank

Concentrate: Water containing the salts and minerals extracted from the raw water.

Raw water: Water from the mains drinking water supply

Treated water: Demineralised water produced by the RO-unit (permeate).

TDS: Total Dissolved Solids
µS/cm: Term describing the conductivity of the water. The lower the number is, the bet-

ter the water quality is.

3

Location of the RO-unit:

!

The RO-unit must be installed in a location with open floor drain







Install the RO-unit in a frost-free location.
Install the RO-unit on an even horizontal surface, otherwise the storage

tank of the RO-unit may overflow.
The surface must be capable of withstanding a weight of approx.

76 kg – RO-Compact1

125 kg – RO-Compact2
138 kg – RO-Compact3

If you install the RO-unit under a work surface, allow a clearance height
of 101 cm for removing the cover. If sufficient space is not available, the
RO-unit can also be pulled out forwards for servicing. In this case, a
flexible hose must be used for the water connection.

Make room behind the RO-unit for the water in- and outlet installations.
It is important that the drain hose does not fold!

Sufficient space must be allowed to the sides and rear of the RO-unit to
avoid blocking the ventilation grids of the integrated pumps.

 The location has an open gully
 Frost-free, even and horizontal surface
 Surface is capable of withstanding a weight of approx. 76 - 138 kg.
 Sufficient place is allowed to the sides and the rear of the RO-unit for in- and

outlet installation and ventilation.

4

Plumbing:

!

The water connections for the RO-unit must meet the requirements of all
present regulations

The RO-unit must be connected to the cold water supply (max 25o).
Install a water shut-off valve and a water meter in the raw water inlet.
Maximum hardness of inlet water 25 odh .( compact 1)

10 odh .( compact 2 & 3)

The water inlet must be sufficiently large (at least ½”)







We recommend the installation of a pressure gauge before the RO-unit to be
able to monitor the water pressure.

!

To protect the RO-unit from dirt the enclosed ¾” micro filter must be
installed between the inlet hose and the inlet of the RO-unit.

This micro filter must be removed and cleaned every 6th month at a minimum
or if the plumbing of the building is being repaired.

 The raw water meets all requirements of present regulations

 Correctly connected to cold water

 Diameter of inlet hose is ½” at least
 Install the filter strainer before the RO-unit
 Maximum hardness of inlet water 25

odh

.( compact1)

10 odh .( compact 2 & 3)

5

Water quality:

!

The raw water, which will be treated in the RO-unit, must be of drinking water
quality and must not contain more than up to 1000 mg/l TDS as CACO3.

In addition to this the raw water must not exceed these limit values for chemi­cal substances:

Fe: 0,05 mg/l
Mg: 0,02 mg/l
Chlorine, free: 0,1 mg/l
NTU, max: 1,0
Silt index SDI: < 3,0
Temp. Max: 25oC
KmnO4, max: 10,0 mg/l
Water pressure: 2 – 7 bar







In case of doubts about the chemical substances of the raw water a water
analysis must be performed.

 The raw water is of drinking water quality

 The feed water to the RO-unit does not exceed the limit values above.

6

Wiring:

!

The electrical connection must be done in accordance with all local rules and
regulations.







Voltage: 230 V – 50 Hz
Fuse: 10/16 Ampere
Electricity consumption: 1,1 kWh compact1 & 2,
1,7kWh Compact 3

Colour-codes for connection cable wires:
Conductor, blue: 0
Conductor, brown: Live
Conductor, yellow/green Earth

 The wiring has the prescribed voltage of 230 V/50 Hz

 Install fuses. Min. 10/16 Ampere

7

Connecting the RO-unit:

 Connect the feed water with a ¾” flexible water connection tube to the micro filter and

the water inlet of the RO-unit (connection point 1).

 Mount a ¾” flexible water connection tube to the outlet connection point of the RO-

unit (connection point 2) and connect the other end to the user application.

!

The connections must be made with a corrosion-resistant tube or pipe made of
stainless steel, plastic or pressure-proof rubber material to food-safe stand­ards, for example. Fully demineralised water can cause other materials to de­compose.

The user application must have a minimum water usages of 1 l/m.

 Mount the supplied 10 mm. plastic tube at the drain connection (connection point 3).

!

The drain tube is correctly connected when it cannot be pulled out without ac­tuating the lock ring.
Connect the opposite end of the drain tube to an open floor drain.

!

Ensure that the drain tube is without kinks and not blocked in any way as this
will ruin the membranes.

 Use a ½” tube to connect the overflow at the back of the unit to an open floor drain.

Cannot be connected to the drain tube with a Tee.

This is a system safety, and the connection should be made to as a part of a proper
installation. If an error occurs at the level control of the RO-unit, excess permeate will
be led to drain.

8

Start-up the RO-Unit:

!

Before start-up check that all plumbing and wiring has been done in
accordance with all local rules and regulations.

 Open the water shot-off valve.
 Check that all water connections are tight.

 Insert the main plug
 Switch on the RO-unit with the toggle switch.

The “No Water Alarm” light flashes approx. 30 times and 3 horizontal lines appear in

the display.
After approx. 7 seconds, the high-pressure pump switches on in order to produce

permeate in the storage tank.

 For venting the RO-unit, turn off the unit 3-4 times at the on/off switch.

The RO-unit is equipped with 3 level sensors. As soon as the midway level is
reached in the storage tank, the 3 horizontal lines start to flash.
Once the upper level is reached in the storage tank, the output in litres per hour ap­pears at the display.
NOTE: If there is water used before it is finished, the display will still show the 3 hori­zontal lines in the display. Because the count was interrupted.

 Check the temperature of the raw water.

9

 As soon as approx. 9 – 11 litres of permeate have been removed, the high-pressure

pump switches on to start permeate production. The time taken depends on the tem­perature of the raw water, but should average around 3 to 4 minutes.

 „No Water“ message lights up, once the RO-unit switches to „By-Pass“
 If the permeate output per hour is too low the „Membrane Alarm“ message lights up.
 If the permeate output per hour is too high the „Membrane Alarm“ message lights up.

!

Check that the RO-unit shuts of automatically in case of too low raw water
pressure or missing water supply.
This can be done by closing the water shut-off valve while the unit is running.
Once the inlet water pressure drops below 1 bar, the RO-unit will shut-off itself.
When the water shut-off valve is opened again and the pressure exceeds 1 bar,
the RO-unit will run again automatically.

 Slowly close the water shut-off while the RO-unit is still running. As soon as the water

supply has been completely turned off, the RO-unit must automatically turn it self off.

 Slowly open the water shut-off again. As soon as the water supply is back to normal

the RO-unit must be running by itself.
The RO-unit is now running and producing permeate. Wait for the level control to stop

the production, the storage tank will be filled with permeate after approximately 15-

17. Minutes. Hereafter the user application can be used with permeate water.

!

Providing that the power is not turned off, the unit will continuously flush the
concentrate side of the membranes with permeate during non-operation peri­ods. This is to prevent dissolved mineral salts to move to the permeate side of
the membranes. It will ensure a permanently high quality of permeate and a
lengthened longevity of the membranes.
