Page 5: General Safety Instructions
General safety instructions Explanations of symbols and instructions This operating manual contains important information on the safe operation of the system. This operating manual, in particular the chapter “Safety instructions” must be observed by all persons working on the system. This applies to the installation company as well as to the system operator. -
Page 6: Personnel Obligations
Personnel obligations All persons who are commissioned to work on the system or who carry out such work inde- pendently undertake the following before commencing work: T o read the chapter on safety and the warnings in this operating manual and to acknowl- edge with their signature that they have understood them. -

C heck the electrical equipment of the installation regularly. Remove loose connections and scorched cables immediately. T he switch cabinet must be kept locked at all times. Access is only allowed to authorised person- nel. I f work on live parts is required, a second person must be called in who can switch off the main switch if necessary. -
Page 8: Safety Instructions For Maintenance Work
Safety instructions for maintenance work T he operator must ensure that all maintenance, inspection, and assembly work is carried out by authorised, qualified technicians who have sufficiently informed themselves by studying the operating manual in detail. B efore carrying out any repair or maintenance work, the system must be switched off and secured against being accidentally put into operation.

Page 9: Safety Instructions For Storage
1.12 Safety instructions for storage CAUTION! The reverse osmosis system is protected by a preservative against microbial contamination and against risk of frost down to -10°C. At room temperature (< 25°C), this preservative must be purged and replaced within 6 months at the latest. At higher temperatures, the protection period is correspondingly shorter (3 months at 30°C). -
Page 10: Principles Of Reverse Osmosis Systems
Principles of reverse osmosis systems Calculation equations The permeate output, the concentrate output and the permeate conductivity are determined by read- ing the corresponding measuring equipment on the system. If no indicating instruments (e.g. variable area flow meter) are present, the permeate output and the concentrate output are determined by manual volumetric measurement. Feed water output permeate output + concentrate output (permeate output [l/h]) Yield [%]... -

Page 12: Transport And Storage
Transport and storage Transport to the customer CAUTION! During transport, all units must be secured against slipping and falling over! Tipping from a fixed position is not permitted! If parts of the equipment protrude from the base area of the pallet, then such protruding parts must not be damaged when further parts/equipment are loaded. T he transport weight corresponds to the tare weight and can be found in the technical data. H owever, the system may be damaged by extreme frost. The units are filled with a preservative/ antifreeze mixture prior to delivery. -

Page 14: Application Limits
Application limits The membranes are wear parts in the longer term. Their service life depends on the feed water qual- ity and the operating conditions. In order to achieve a projected membrane service life of 3 years, the reverse osmosis systems should be operated with softened water or with hard water according to the system type, in each case in the same quality as drinking water according to the German Drinking Water Ordinance and according to the following additional specification: Parameter... -

Page 16: Function
4.3.2 Function The RO feed water reaches the HP pump via a residual hardness monitor (optional accessory, only when using softened water) and a protective cartridge filter (grade of filtration 5 µm). This pump con- veys the water at high pressure (level depends on the size of the system and the desired permeate pressure) through the semi-permeable membranes. Water largely freed from salts passes through the membranes and forms the permeate (desired product). -

Installation and assembly Installation 5.1.1 Requirements of the installation site T he space required for the unit is derived from the dimensions specified in the technical data. In addition, there should be 0.8 m of space in front of the unit to allow access for operation and 1.0 m of space to the side for maintenance. T he place of installation must comply with the ambient conditions as specified in the technical data. -

Page 34: Flushing The Concentrate
W hen flushing the concentrate, the concentrate side of the membrane(s) is flushed at a higher speed due to the increase in the concentrate volume flow and, due to the associated increase in shear forces, easily detachable deposits are removed and flushed out. Flushing the concentrate should last at least 60 minutes and should be carried out as follows: Log the actual values (enter in operations log according to chapter H) Open the concentrate control valve completely or remove the concentrate screen (depending on the type of system). -
