DEAR CUSTOMER!
1. PURPOSE OF THE PRODUCT
Thank you for choosing our products.
We want you and your family to enjoy clean drinking water. With Ecoso lter you will forget
the trouble of using large boles. Pure spring water for drinking, cooking and making drinks will
always be at hand. Please read this instrucon manual and check validity of the warranty card
before using the system.
Reverse osmosis is by far the most advanced technology of water puricaon in use today. Special
semipermeable membrane structure similar in its properes to the membrane of a living cell
is capable of purifying drinking water from virtually all harmful impuries (see Figure 1). The
membrane can be conceived of as having ny pores, 200 mes smaller than viruses and 4000
mes smaller than bacteria. Domesc water lters with reverse osmosis membranes harness the
principle of body’s metabolism on a cellular level. Only molecules of certain size can penetrate
cellular membrane.
Direct ow reverse osmosis lter CROSS 90 is a four-stage in three steps ltraon unit with
three cartridges funconing as follows (see secon (2.3) for reference numbers). Filter rack is
connected to cold water supply with feed water adapter (4). White tube (3/8”) carries water from
feed valve through low pressure switch and inlet solenoid valve to the CF lter cartridge. Incoming
water then passes through pre-lter cartridge (7). Pre-lter cartridge is a complex cartridge with
(2) stages inside. It is designed to remove solids (such as rust, sand, silt, etc), residual chlorine,
and organochlorines from water. Aer undergoing pre-treatment steps in the pre-lter, water
enters into the third (and the most important) stage: reverse osmosis membrane (7) contained in
a cartridge RO. One of the two outlets supplies puried water (permeate), and the other carries
away water with rejected impuries (concentrate). The membrane puries water at the molecular
level by passing through its pores only the water molecules and the molecules of dissolved oxygen.

2. SPECIFICATIONS AND COMPONENTS
2.1 SPECIFICATIONS AND REQUIREMENTS
Inside the membrane, water is separated into two streams: concentrate, which is discharged into
drain, and permeate, which enters next step – post-lter (7).
Aer opening the puried water valve (3), the pressure in the system drops and the high pressure
switch is acvated, opening the inlet valve and starng the pump, automacally resuming the
ow of water through the pretreatment cartridge to the membrane. Aer opening the puried
water valve (3), the pressure in the system drops and the high pressure switch is acvated,
opening the inlet valve and starng the pump, automacally resuming the ow of water through
the pretreatment cartridge to the membrane. The puried water aer the membrane enters
the fourth stage of puricaon — the CB carbon post-lter, designed for nal water puricaon.
The puried water aer the membrane enters the fourth stage of puricaon — the CB carbon
post-lter, designed for nal water puricaon. It contains extruded acvated carbon. This lter
improves the taste and smell of the puried water. This lter is direct-ow, so no water storage
tank is required. With a capacity of 600 GPD (90 l/h), it takes only 8 seconds to ll a 200 ml glass.
* If supply water pressure is below required value, purchase pumped model or t your exisng
lter with booster pump. If the pressure in the water system is above the limit, it is necessary to
install a pressure regulator on the main pipe. If pressure in tank bladder is outside this range, it is
necessary to pump up or release the pressure unl it conforms to the requirement.
** If supply water temperature is up in the range of +20…+30 °C, rejecon of impuries will be
decreased and system capacity increased, bringing about an increase in TDS. Using the product
with supply water temperature in excess of +30 °C is not recommended.

Do not use with water that is microbiologically unsafe or of unknown quality without adequate
disinfecon before or aer the system.
* If water supply does not meet the requirements, service life of membrane and/or pre-lter
cartridges may be shortened.
** If your home is supplied with raw well water, perform laboratory test of your water before
in- stalling a reverse osmosis lter. If any of your water indices exceed the limit, consider using a
water treatment system to correct supply water quality. Refer to water treatment specialists or
companies for advice and proper equipment selecon.
* Values are determined under the following
condions: temperature of supply water is
25 °C, supply water quality and operaon
condions correspond to manufacturer’s

1. Remove the reverse osmosis system from its packaging and check the equipment.
2. Shut o water supply in your kitchen or whole home and open water tap where you are about
to install the system (on your kitchen sink) for 1 minute to relieve pressure in the system, and
then close it.
3. Screw the feed water adapter with valve (4) into the cold water plumbing.
Connecons size is selected to t most common size ½ inch pipe. If your pipe is of another size,
prepare an appropriate adapter.
4. Unscrew the compression nut from the feed valve (4) and put it on the 3/8” white tube. Push
the white tube on the end of feed valve’s ng and screw on the compression nut. Connect the
free end of the 3/8” white tube with the quick connect ng “Inlet” on the connecon panel of
the rack. Insert the 3/8“ quick coupling lock plate between the quick connect and the claw of the
water inlet pipe.

5. Connect the drain saddle (6) with drain pipe from
the kitchen sink. The drain saddle is compable
with most standard drain pipes. Drill a hole of 5.0
mm (0.2”) diameter in the kitchen sink drain pipe,
apply rubber gasket with scky base (included in
the package).
Install the drain saddle (6) on the drain pipe over
the hole. Tighten screws on drain saddle with a
screwdriver. Insert red tube into the connecon on
the clamp. Connect the other end of the red tube
with concentrate outlet “Waste” on the connecon
panel of the rack. Insert 1/4” quick coupling lock
plate between quick coupling and jack catch of pipe.
6. Connect one end of 1/4” white tube to
the “Filtered” output on the connecon
panel of the rack. Insert the 1/4”quick
coupling lock plate between the quick
connect and the claw of the water inlet
pipe.
CAUTION! If RO systems do not use air gap faucets, it is required that they be plumbed in with
a physical air gap between the waste water outlet and the drain. This is so if the drain backs
up, sewage will not push up into the RO system.
