RO-202S
REVERSE OSMOSIS SYSTEM
**Operation manual

**

Introduction

RO-202S REVERSE OSMOSIS SYSTEM (hereinafter referred to as RO-202S) is manufactured by WestaquaInvest OÜ (Estonia).
RO-202S is intended to purge of mechanical and colloidal particles, organic impurities and to remove foreign flavour, odour and colour when post-treating cold drinking water supplied via municipal and local water supply networks (water from artesian boreholes, wells, etc.) to meet the requirements, specified in this Manual.
RO-202S works on the principle of transferring water molecules through a semipermeable membrane by applying a overbalanced osmotic pressure. This pressure increases with increasing water salinity, so the higher the water salinity, the greater water supply pressure is required to keep RO-202S operating.
RO-202S is made of safe, non-toxic materials ensuring that no substances hazardous to human health and the environment are released into the water. RO- 202S meets EC hygiene requirements.

Design and Function of RO-202S

1. The RO-202S housing (1) consists of a top plate, a cover, a stand, a storage tank and a front panel.
   Four collectors (for removable filter cartridges) and a hydraulic unit are fixed in the top plate.
   The top plate is covered with a decorative cover, equipped with a handle fixing the cover in its central part. A pump is installed in the lower part of the housing (stand) to increase the water pressure in RO-202S.
   RO-202S is equipped with a storage tank for treated water to provide with a desired quantity of the water at any time.
   At the front, the RO-202S housing is covered with a decorative panel where an electronics unit and control elements are located.

2. K1 and K2 replaceable filter cartridges are part of the water pre-treatment unit (2). The water pretreatment unit is designed to remove impurities from the water such as iron hydroxide and active chlorine that can damage the reverse osmosis membrane.

3. The reverse osmosis membrane unit (3) includes a replaceable membrane cartridge. The reverse osmosis membrane unit removes organic and inorganic compounds and salts from water as well softens it.

4. The water conditioning unit (4) includes a К7ВМ microfiltration mineralizing cartridge. The water conditioning unit removes bacteria from the water, including Lamblia cysts*, foreign odours, improves the water taste, as well as mineralizes the water.

ATTENTION! The RO-202S performance depends on the pressure in the water supply system. No proper operation of RO-202S is guaranteed at pressures below 90 kPa in the water supply system.

• Tested on: Escherichia coli 1257, Enterobacter cloacae, Pseudomonas aeruginosa, coliphage f-2, Bac. thuringiensis.

Safety

RO-202S is designed to post-treat and soften water from municipal water supply systems that meet sanitary standards.
It is recommended to analyse the source water for compliance with national standards for drinking water when installing RO-202S outside municipal water supply systems.

• The service life of the pre-treatment unit and the reverse osmosis membrane may be reduced if the source water does not meet the requirements of national standards for drinking water.
• It is recommended to install additional water treatment systems (iron removers, softeners, disinfectants, mechanical filters, etc.) if the source water significantly differs from the  requirements of national standards for drinking water.
• It is recommended to analyse the treated water for compliance with national standards for drinking water after your RO-202S is installed.
• Further, the treated water should be tested regularly (once a year) to make sure your RO-202S functions properly.
• An additional test is recommended if the taste or smell of the water changes.
• If the test results are unsatisfactory, it is not allowed to drink the water, and you should contact your service provider.
• It is recommended to use RO-202S as a posttreatment unit for microbiologically safe water, although this reverse osmosis system can trap out bacteria and viruses from the source water.
• Do not use the system to treat unknown water without additional disinfection.

Empty and refill the tank 3 times for flushing before use if you have not used your system for more than 2 weeks. Treated water is not subject to long-term storage.
It is recommended to use fresh filtered water. It is disposed of in accordance with environmental, sanitary and other requirements set forth in national standards for environmental protection and ensuring the sanitary and epidemiological welfare of the population.
