Introduction
Aquaphor RO operates by removing contaminants from water at the molecular level. By using your household water pressure to squeeze the water against a special  membrane, the water molecules are separated from any impurities that exist.
Rejected dissolved solids are automatically rinsed away through the drain leaving you with only high-quality, delicious water for your use.

Operational parameters

(1.9 bar / 27.6 psi)
| The operating pressure in your home should be tested over a 24 hour period to attain the maximum pressure. If it is above 0.63 MPa (6.3 bar / 91.4 psi), then a pressure regulator is necessary, and will be required.

Hardness:| Recommended water hardness should not exceed 350 ppm as CaCO3 (20.5 grains per gallon). The system will operate with hardness over 350 ppm (20.5 gpg), but the membrane cartridge life may be shortened. The addition of a water softener may lengthen the membrane cartridge life.

Table 1. The dependence of minimum necessary operating pressure of the water purifier from mineralization.

ATTENTION!
The efficiency of RO depends on the incoming tap water mineralization and tap water pressure (please see Table 1). The recommended operation of RO requires tap water pressure of at least 0.2 MPa (2 bar / 29.01 psi).
When tap water pressure is less than illustrated in the Table 1, it is highly recommended to install a booster pump in order to obtain drainage ratio.

Safety instructions

WARNING: RO must be applied to potable water only.
It is highly recommended that a water treatment specialist be hired to install and maintain this appliance.
When installing the appliance into a local water supply, it is recommended that you conduct a full water analysis. If the water analysis does not correspond with the  requirements, the life of the filtration and membrane cartridges may be significantly reduced. In this case, it is recommended to use auxiliary water treatment systems (e.g. mechanical filter, de-ironing filter with, or alongside a water softener). Only use microbiological safe water with your Reverse Osmosis system appliance.

CAUTION: Do not use water that is microbiologically unsafe or water of unknown quality without adequate disinfection before or after using the appliance.

CAUTION: Reverse Osmosis water should not be run through copper tubing as the purity of the water will leach copper and cause an objectionable taste in the water. Additionally, it will form pinholes in the tubing. Be sure to follow any state or local regulations.
CAUTION: The Reverse Osmosis system is designed to be connected to cold water only. Never run warm or hot water through your appliance.

RO design and operation principles

• RO housing (1) consists of an upper plate, with four collectors fixed onto it, to place the replacement cartridges and the RO-hydro automatic unit RO. The upper lid comes with a decorative cover, fixed in place with three plastic latches. An integral part of the RO housing is the treated water storage tank (6). Treated water goes into the storage tank upon exiting the membrane cartridge. This storage tank ensures availability of the required amount of filtered water always.
• Preliminary water treatment block (2, 3) includes replacement filter cartridge includes replacement filter cartridge K5 (for RO-101S, RO-102S, Aquaphor RO-101S IL, Aquaphor RO-102S IL) (3) or cartridge K1 (for RO-101S EU, RO-102S EU) (3) and K2 (2). The preliminary water treatment block removes any impurities that can damage membrane cartridge, such as ferric hydroxide and active chlorine.
• Reverse Osmosis membrane block (4) includes the replacement membrane cartridge Aquaphor RO-50S (for RO-101S, RO-101S EU, Aquaphor RO-101S IL) or Aquaphor RO-100S (for RO-102S, RO-102S EU, Aquaphor RO-102S IL) and purifies water by removing organic compounds, non-organic compounds, and salts while sof- tening water.
• Water conditioning block (5) includes the mineralizing cartridge K7M (for RO-101S, RO-102S, Aquaphor RO-101S IL) or K7BM (for RO-101S EU, RO-102S EU, Aquaphor RO-102S IL). The water conditioning block eliminates unwanted odors and flavors from water while mineralizing the water.

How RO works
The water coming from the cold water mains enters RO and passes through the preliminary water treatment block. From there, water enters the Reverse Osmosis membrane block via the automatic check valve. The unit housing the membrane cartridge has two outlets: the treated water outlet and the drain water outlet. On its way to the drain, the water will also pass through a flow restrictor. The flow restrictor flushes the drain water that goes down the drain. The treated water enters the storage tank that has a built-in membrane. This separates the tank into two chambers: storage and technical. The storage chamber contains the fully purified drinking water, while the technical chamber contains water from the mains. As clear water collects, water from the mains is forced from the technical chamber into the drain, also preventing the accumulation of clear water. When the storage tank is full, the automatic check valve cuts off the water intake into RO.

When the clean water faucet is opened, water from the mains enters the technical chamber via the shutoff valve and forces treated water from the storage chamber through the faucet via the conditioning block. The automatic check valve then triggers and opens water supply to the RO-storage tank.

RO installation

ATTENTION!
Only install your RO by a qualified plumber who is certified to perform the installation in accordance with state law. Locate the appropriate installation place for the faucet and RO. Take care to ensure that the delivery tubes are pulled freely, without over bending. RO must be installed on a flat, even solid surface as installation on an uneven surface may cause vibration or noise. Additionally, RO must be located away from heat sources, such as kitchen ovens, hot water supply pipes, dishwashers or washing machines, or at least isolated from such heat sources.

Picture 4. RO installation scheme

Connection node assembly

• Turn the water off at the cold water main.
• Open the kitchen faucet to discharge pressure into the water line.
• Unscrew the nut from the flexible line cap, leading to the faucet on the cold water main.

ATTENTION! Residual water will be left inside of the flexible JG tube after discharge of water.
When disconnecting the flexible line, please use a 200 ml or similar size container to drain the water left behind in the tube.

• Screw the cap nut off the connection node and on the cold water main thread.

• Screw the cap nut off the flexible line, and then on the connection node thread.

• Set the shutoff valve on the connection node to the closed position and then make sure that the connection is completely leak-proof by supplying water to the cold water
  main.

• Connect JG tube (follow the instructions below to correctly connect the JG tubes).

ATTENTION! Make sure that the sealing O-Ring is located correctly in its place and not damaged during installation.

Connection of JG tubes
Pull the locking clip (2) off the plastic plug (1). Then install the previously wetted end of the tube (3) into the fitting piece approx.15 mm up to the stop. Next, put the locking clip (2) back.
Make sure that the tube (3) is tightened correctly: the tube should not be pulled out by force greater than 8-10 kgf.
Figure 6. Connection of JG tubes

Disconnection of JG tubes
Pull the locking clip (2) off the plastic plug (1), then pull the tube (3) out by applying pressure on the face of the connecting piece. To apply pressure, use the tube  disconnection key (4) included in the water filter set.
Figure 7. Disconnection of JG tubes

Clean water faucet installation

• Drill the hole in the sink (table top) 12 mm diameter;
• Put on the thread tail of the faucet (11) rubber gasket (2), decorative stand (3), rubber gasket (4) and insert the faucet into the hole in the sink;
• Underneath the sink, put plastic (5) and metal (6) lock washers on the thread bushing and screw on the fastening nut (7);
• Put on the captive-nut (9) on the plastic pipe (10) with pressed metal bushing (8) (fig. 8) and screw on the nut onto the tail end of the faucet.

ATTENTION!

• When you replace the original tap with a different one, there may be noise when you open it, and clean water flow reduction from the tap may occur.
• When you replace the original pipes with the longer ones, there may be noise and clean water flow reduction from the tap.
• If the water filter has not been used for a long time, the valves may turn on, making short-term noise. It is not a sign of the system malfunction.
• Open the clean water tap fully when you use the water filter, otherwise noise may occur. It is not a sign of the water filter malfunction.

Figure 8. Tube connecting to the clean water faucet procedure

Drain saddle installation

Figure 9a. Drain saddle components

It is best install the drain saddle on the sink drain before the siphon trap or bend (the drain saddle on most drain pipes is of ~40 mm diameter).

1. Apply the part of the collar with the fitting to the pipe to determine the optimal position of the collar and the pipe hole.
2. Drill a 7 mm hole in the planned tube location on the tube pipe.
3. Remove the cut circle from the sealing gasket (1).
4. Remove the protective tape (2) from the sealing gasket (1). Place the sealing gasket (1) on the collar inner side, so that the hole in the gasket meets the hole in the collar fitting.
5. Install the collar onto the pipe, carefully align- ing the hole in the fitting with the drilled hole; tighten the bolts (3). The bolts must be tightened evenly in such a way that the two parts of the collar are located in parallel.
6. Put the plastic nut onto the JG drain tube (1/4”, black) so that the tube is protruding from the other side of the nut by a length of 20 mm (see figure 9b).

To eliminate any noise from the water in the drain saddle, push the JG tube deeper into the pipe.

Slotted plug installation

ATTENTION! To avoid any incorrect installation of the membrane cartridge and the resulting loss of sealing of the RO connections, it is not recommended to dissemble it without a fully qualified maintenance specialist. If the RO connections are leaking, immediately close the tap on the connection unit and check the cartridges for correct installation.

Recommended filter replacement

The frequency at which the filter and membrane cartridges should be replaced depends on the quality of the water that enters the appliance. Contact your water treatment  specialist for replacement filters and parts.
NOTE: The installation of the RO appliance on a pre-treated water supply will greatly increase the life of its filters.

Table 3. Recommended filter replacement

Once purchased, the cartridges can be stored for three years from the manufacturing date.

Recommended filter maintenance

The frequency at which the filter and membrane cartridges should be replaced depends on your tap water quality.
Note: Any filter that demonstrates reduced water production or a slower rate of flow is likely to be overdue for a change.

WARNING: Shut off the water to the appliance before beginning any maintenance work.

• Depending upon storage, transportation and operation conditions, complete flushing of the membrane cartridge may take up to 24 hours.

Replacement of filter cartridge К5 / К1 (1)
Reduces dirt and other sediment particle matter of 5 micron or larger in the incoming water. Replace the К5 / К1 filter cartridge every three months.

Replacement of filter cartridge K2 (2)
This reduces free chlorine from the incoming water and protects the membrane from any chlorine degradation. Changing frequency of the replacement filter cartridge K2 should be based on the free chlorine levels in the incoming water. If the free chlorine is 1 ppm or less, then the replacement filter cartridge K2 should be replaced once a year. If the free chlorine level is greater than 1 ppm, then the replacement filter cartridge K2 should be replaced once in every six months.

Replacement membrane cartridge RO-50S / RO-100S (3)

The semi-permeable membrane cartridge (3) separates the majority of the remaining suspended solids and most of the dissolved solids from the water molecules. These separated impurities are then washed down the drain. The membrane cartridge (3) is critical for the effective reduction of total dissolved solids (TDS). The treated water should be tested periodically to verify that the appliance is performing satisfactorily. A noticeable change in water quality and taste may occur. If this happens, it is an indicator that a filter change is needed. Replace the membrane cartridge at least once a year.

Replacement filter cartridge K7M / К7ВМ (4)

The replacement filter cartridge K7M or К7ВМ (4) is the final stage of filtration. It filters the water and enriches it with useful minerals that improve not only the taste, but also maintains the correct drinking water salt balance. You should replace the post filter every 6 months.
