CAREL Industries reverse osmosis (RO) systems are advanced products,

whose operation is specied in the technical documentation supplied

with the product or can be downloaded, even prior to purchase, from the

website www.carel.com. Each CAREL product, in relation to its advanced

level of technology, requires setup/conguration/programming to be able

to operate in the best possible way for the specic application. Failure to

complete such operations, which are required/indicated in the user manu-

al, may cause the nal product to malfunction; CAREL accepts no liability in

such cases. The customer (manufacturer, developer or installer of the nal

equipment) accepts all liability and risk relating to the conguration of the

product in order to reach the expected results in relation to the specic

nal installation and/or equipment. CAREL may, based on specic agree-

ments, act as a consultant for the installation/commissioning/use of the

unit, however in no case does it accept liability for the correct operation

of the RO system and the nal installation if the warnings or suggestions

provided in this manual or in other product technical documents are not

heeded. In particular, as well as observing the above warnings and sug-

gestions, the following warnings must be observed for correct use of the

product:

ELECTRIC SHOCK HAZARD: the RO system contains live electrical com-

ponents.Disconnect the mains power supply before accessing inside

parts or during maintenance and installation.

WATER LEAK HAZARD: the RO system automatically and constantly lls/

drains certain quantities of water. Malfunctions in the connections or in

the humidier may cause leaks.

Environmental conditions, fuel and power supply voltage must all com-

ply with the specied values. All other uses and modications made to

the appliance that are not authorised by the manufacturer are considered

incorrect. Liability for injury or damage caused by the incorrect use of the

appliance lies exclusively with the user.

Please note that the appliance contains live electrical devices. All service

and/or maintenance operations must be performed by specialist and

qualied personnel who are aware of the necessary precautions and are

capable of performing the operations correctly and in accordance with

the safety standards and legislation in force, with specic reference to:

1. Italian law no. 46/90: “Safety standards relating to systems in buildings”;

2. Italian Presidential Decree no. 447 of 6 December 1991:“Regulations for

the enforcement of law no. 46, dated March 5, 1990, on safety relating

to systems in buildings”;

3. Italian law no. 10/91: “Regulations for the enforcement of the national

plan for energy savings and the development of renewable sources of

energy”

Safety Instructions

WTS +0300130EN rel. 1.0 - 05.09.2022

2. SAFETY INSTRUCTIONS

These safety instructions are required by law. They promote workplace safety and accident prevention.

2.1 Guidelines for Safe Operation

2.1.1 Scope

Comply with the accident prevention regulation„DGUV Regulation 3“ to prevent injury to yourself and others. Beyond

that, national regulations apply without restrictions. This way you can protect yourself and others from harm.

2.1.2 Unit control

Do not perform any work which compromises the safety of the unit. Obey all safety instructions and warnings present

on the unit.

In case of a malfunction or electrical power disruption, switch off the unit immediately and prevent a restart. Repair

malfunctions promptly.

Caution: Restricted use.

IEC 60335-1 stipulates as follows:

This device may be used by children of eight years of age and above as well as by persons with reduced physical,

sensory or mental capabilities or lack of experience and knowledge so long as they are supervised or have been

instructed regarding the safe use of the device and understand the hazards that may result from it. Cleaning and

maintenance of the unit must not be undertaken by children without supervision.

Notice: The installation room must be adequately ventilated and be equipped with a floor drain. A water stop

mechanism (e.g. leakage detector) can be used as an alternative.

2.1.3 Unit operation

Caution: Danger of scalding!

Hot surfaces can cause injuries. Protect yourself with suitable protective equipment.

Notice: Water leaks possible due to defective connections or malfunctions.

• Before starting work, the water supply to the reverse osmosis system (RO system) must be shut o.

• The system may be under pressure. Release pressure before starting work.

• The reverse osmosis (RO) systems continuously produce permeate (product water) and concentrate (waste water).

Connections and water-carrying components must be checked regularly for correct functionality.

Notice: Risk of material damage!

• The unit may be damaged if switched on repeatedly following a malfunction without prior repair. Rectify defects immediately!

• Regularly check that all safety and monitoring devices are functioning normally. Do not remove or disable safety devices.

Notice: It is essential to leave the RO system connected to the power supply permanently. Only then the automatic

rinsing can be carried out (protection against germs).

Switch device ON/OFF

The system can be switched on/off in different ways:

» Interrupt the power supply (pull the plug) or

» operate the main fuse switch (only ROL units) or

» press the ESC key (for about 2 seconds).

2.1.4 Mounting, dismantling, maintenance and repair of the unit

Notice: the CAREL reverse osmosis units are IP20 protected. Make sure that the unit is not object to dripping water

in the mounting location.

Notice: Do not install CAREL reverse osmosis systems above electrical equipment such as fuse boxes, electrical

appliances, etc. In the event of a leakage, leaking water can damage the underlying electrical systems.

Notice:

• Use genuine spare parts only

• After any repair work, have qualied personnel check the safe operation of the unit

• Attaching or installing of additional components is permitted only with the written consent of the manufacturer

ENG

Safety Instructions WTS +0300130EN rel. 1.0 - 05.09.2022

2.1.5 Electrical

Caution: Risk of electrical shock!

Hazardous electrical voltage!

Any work on the electrical system to be performed by certified expert staff (electricians or expert personnel with

comparable training) only.

During maintenance or installation work, the device must be disconnected from the power supply and secured against

being switched on again. The absence of voltage must be ensured by a measurement.

After electrical installation or repair work, test all safety mechanisms (such as grounding resistance).

Notice

Use only original fuses with the appropriate amperage rating.

Regularly check the unit‘s electrical equipment. Promptly repair any damage such as loose connections or burned

wiring.

Responsibility for intrinsically safe installation of the CAREL reverse osmosis unit is incumbent on the installing specialist

company.
