Introduction
AQUAPHOR RO-101S 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 sepa-
rated 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.
1. Operational parameters
Operating temperatures: Maximum 100.4 ºF (38 ºC) Minimum 41 ºF (5 ºC)
Operating pressure: Maximum 91.4 psi (6.3 bar) Minimum 27.6 psi (1.9 bar)
The operating pressure in your home should be tested over a 24 hour
period to attain the maximum pressure. If it is above 91.4 psi, then a
pressure regulator is necessary, and will be required.

ATTENTION
The efciency of RO-101S depends on the incoming tap water mineralization and tap water
pressure (please see Table 1). The recommended operation of RO-101S requires tap water
pressure of at least 29.01 psi / 2 bar.
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.
2. Safety instructions
Warning: RO-101S must be applied to potable water only.
It is highly recommended that a water treatment specialist is 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 ltration and membrane
cartridges may be signicantly reduced. In this case, it is recommended to use auxiliary water treatment sys-
tems (e.g. mechanical lter, de-ironing lter with, or alongside a water softener). It is recommended that you 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-101S housing (1) consists of an upper plate, with four collectors xed onto it, to place the
replacement cartridges and the RO-hydro automatic unit RO-101S. The upper lid comes with a decorative
cover, xed 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 ltered water always.

Preliminary water treatment block (2, 3) includes replacement lter cartridge K5 (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 and puries water by removing organic compounds, non-organic compounds, and
salts while softening water.
Water conditioning block (5) includes the mineralizing cartridge K7M. The water conditioning
block eliminates unwanted odors and avors from water while mineralizing the water.
Attention!
The mineralizing cartridge K7M can be replaced with the K7 cartridge.
How RO-101S works
The water coming from the cold water mains
enters RO-101S and passes through the pre-
liminary 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 out-
lets: the treated water outlet and the drain
water outlet. On its way to the drain, the wa-
ter will also pass through a ow restrictor.
The ow restrictor ushes 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 puried drinking water, while the techni-
cal 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-101S.
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.

ATTENTION! To avoid any incorrect installation of the membrane cartridge and the resulting
loss of sealing of the RO-101S connections, it is not recommended to dissemble it without a
fully qualied maintenance specialist. If the RO-101S connections are leaking, immediately
close the tap on the connection unit and check the cartridges for correct installation.
11. Recommended lter replacement
The frequency at which the lter and membrane cartridges should be replaced depends on the quality of
the water that enters the appliance. Contact your water treatment specialist for replacement lters and parts.
* The K7 cartridge is not included in the water lter set and is sold separately.
** Depending upon storage, transportation and operation conditions, complete ushing of the membrane cartridge may take
up to 24 hours.

AQUAPHOR RO-101S REVERSE OSMOSIS SYSTEM 17
Note: The installation of the RO-101S appliance on a pre-treated water supply will greatly in-
crease the life of its lters.

Replacement lter cartridge K7M (4) 12
Once purchased, the cartridges can be stored for three years from the manufacturing date.
12. Recommended lter maintenance
The frequency at which the lter and membrane cartridges should be replaced depends on your tap water
quality.
Note: Any lter that demonstrates reduced water production or a slower rate of ow is likely
to be overdue for a change.
Warning: Shut off the water to the appliance before beginning any maintenance work.
Replacement of lter cartridge K5 (1)
Reduces dirt and other sediment particle matter of 5 micron or larger in the incoming water.
The replacement of the lter cartridge K5 is necessary every three to six months.
Replacement of lter cartridge K2 (2)
This reduces free chlorine from the incoming water and protects the membrane from any chlorine degradation. Chang-
ing frequency of the replacement lter 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 lter cartridge K2 should be replaced once a year.
If the free chlorine level is greater than 1 ppm, then the replacement lter cartridge K2 should be replaced once
in every six months.
Replacement membrane cartridge Aquaphor RO-50S (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 lter change is needed. Replace the
membrane cartridge at least once a year.
Replacement lter cartridge K7M (4)
The replacement lter cartridge K7M (4) is the nal stage of ltration. It lters 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 lter every 6 months.
