2 HOW THE LINEGUARD WORKS
2.1 Filtration mode
The LineGuard membrane modules contain hundreds of capillary ultrafiltration (UF) membranes. The porous walls of these hollow fibers contain billions of microscopic pores which act as an ultra-fine sieve. The water pressure pushes water molecules and vital minerals from the inside-out through the pores of the membrane fibers, while retaining larger contaminants such as bacteria, parasites and viruses. Automated cleaning cycles periodically flush out the contaminants retained inside the membranes. Once the LineGuard has been installed on the main water supply line, the water is filtered by the membrane modules.
2.2 Cleaning cycles
Contaminants in the water foul the inner surface of the membranes, which affect the performance of the system. The LineGuard is equipped with a control unit that sets automated cleaning cycles so that this fouling is periodically flushed out. There are two types of cleaning cycles: a forward flush and a backwash.
In a forward flush the membranes are flushed with feed water. The feed water flows through the inner part of the membranes at a much greater speed than in the filtering mode. Because of this high flow and the resulting turbulence, the fouling on the membrane is released and discharged. The flush water is discharged to the system drain. Particles that are caught in the membrane pores are not released and can only be removed with a backwash. Please note that the backwash needs backpressure from the water line after the system for an optimal cleaning cycle. Whenever the LineGuard discharges to an open system, like a water tank, the backwash will be not be performed at an optimal level.
A flow sensor will prevent the system from flushing when in use. Whenever water is used at the moment of a scheduled cleaning cycle the system will wait and resume the cleaning cycle 30 seconds after the water usage has stopped. Whenever large quantities of water are used, additional cleaning cycles should be performed. This is done by setting a flush volume in the control unit. Upon reaching this volume a cleaning cycle will be performed. A volume flush will overrule the normal flush interval.
Whenever low quality feed water is used, the performance of the system might decrease rapidly. The performance of a filter module is determined by the “flux” (defined as the quantity of permeate that passes through the membrane surface per amount of time). A cleaning cycle can also be performed by setting a flux flush. For example, when a flux flush of 10% is set, a cleaning cycle will be performed when the flux over the filter modules is decreased by 10%. A flush flux will overrule the normal flush time interval. A cleaning cycle will take place whenever the flush volume or flux flush is reached. After the cycle, these settings will be reset.
2.3 Parallel installation of multiple LineGuards
A LineGuard UF-100 has a initial flow rate of 60 l/min (3.6 m3/h). In case more capacity is needed, parallel installation of up to five LineGuard systems is possible. Please contact your installation company for details and a preferred installation scheme. In case multiple LineGuards are installed, they will be part of bigger installation which might have a constant demand for water that will permantently overrule the flushing cycles. This will have a negative influence on performance of the system. In this case a flushing overrule should be set (see 4.3.2.7). The flushing cycles of multiple LineGuard need to be set out-of-phase (see 4.3.2.1)
A backwash is performed by reversing the filtration process. Filtered water (or permeate as it is called) is flushed from the outside to the inside of the membranes. This way, particles that are caught in the membrane pores are released and discharged. In a backwash the LineGuard uses permeate from one module to backwash the other so that the modules will not foul at the ‘clean side’. The flush water is discharged to the system.
The LineGuard is set to automatically perform one 30 second flush cycle a day at 01:00 am. Frequency, duration and time can be adjusted by setting the control unit of the system. The optimal duration and frequency of the flush cycle depends on the water quality and usage. On average one flush per day should be sufficient. Your installation company can advise you on the right settings.

3 INSTALLATION OF THE LINEGUARD
1 - Drain
The LineGuard membrane filtration system should be installed in the main water supply line near its entry into the building. It should be placed at any point past the main shut-off valve, before the pipes branch off into multiple directions. This manual provides general guidelines for the installation. Please keep in mind that the installation must always comply with all local and national plumbing guidelines and should be carried out by a certified installation company.
3.1 Mounting the LineGuard
The LineGuard should be attached to the wall with suitable fasteners. The wall has to be flat and the material must be strong enough to support the LineGuard. In order to allow enough built-in space for the water pipes and for the display to be at a readable height it is recommended to mount the LineGuard at 600 mm (2 feet) above floor level. At least 100 mm (4 inches) of clear space is recommended at the top for releasing the modules.
3.2 Piping installation
The LineGuard membrane filtration system should be placed on the main water supply line near its entry into the building. It can be situated at any point past the main shut-off valve, but before the pipes branch off into multiple directions. To install the LineGuard, three 22 mm pipe ends must be connected. See the figure below. An adapter 22 mm to 3/4 inch is included.
Please review the recommended piping schematic below for a correct installation. A full installation scheme is included in the back of this manual. Please note that any alteration to this might lead to problems with servicing the LineGuard.

A shut-off valve should be placed directly on both the feed and filtered water pipes of the LineGuard (figure 2, position 1 and 3). A shut-off valve with an integrated drain valve is recommended for ease of installation. We strongly recommend using a fully integrated controllable check valve (a backflow preventor) at the feed water side. This offers a efficient protection against pollution of the drinking water system. The maximum system pressure should not exceed 4 bar. In case of potentially higher water pressure, a pressure reducing and relief valve (figure 2, position 7 and 8) must be installed between the main shut-off valve and the LineGuard. The diameter of the drain should at least be two pipe diameters (44 mm or 2 inch).
Figure 1: Connecting the LineGuard
Warning: before installing the LineGuard please thoroughly disinfect the piping structure behind the LineGuard. Any biofilm that may be in the piping could contaminate the filtered water from the LineGuard!
Please note that the capacity of the drain should be large enough to discharge the flow during flushing cycles. A ‘rule of thumb’ in this: measure the flow of the waterline system without mounting the LineGuard (the maximum flow at this point of the system). The capacity of the drain should at least meet that flow. If this is somehow not possible, we advise you to mount a valve on the drain pipe. You should set this valve during the start-up procedure (see 3.5). Make sure you seal this valve afterwards.
