Do not use with the water that is microbiologically unsafe or of unknown quality without
adequate disinfection before or after system.
•
System must be installed indoor.
•
It is recommended that installation of the water filter be done by a professional plumber.
Important !
It is recommended to change the 2 pre-filters at least every
TINY-SET-2
3-5 months. It is advised to change them on time to avoid any
damages to the RO System. It is advised to use WECO replacement
filters. Using ‘non-WECO’ and poor quality filters may clog the
RO system and will also damage the membrane.

INSTALLATION INSTRUCTIONS
Tapping into the cold water line
TINY Manual
(Using the water supply adapter model FW 1)
NOTE: The drinking water system must be connected to the COLD
water supply only.
1. Turn off the cold water supply to the sink faucet
by locating the Round or oblong handle on the
right side of the sink cabinet and Turning clockwise
until the water supply is off.
NOTE: If the cold water shut-off valve fails to turn off the water, the
house water supply can be turned off at the main water supply.
2. The water supply adapter can be installed at the faucet Connection (A of Fig. #5) of the cold
water line or at the shut-off Valve connection (B of Fig. #5).
3. Disconnect the threaded nut at the connection and thread the water supply adapter, with
the flat washer in place, onto the connection and tighten. Connect the white tubing to the
water supply adapter with the treaded nut and tighten.
4. Thread the needle valve into the adapter tightly and turn the handle clockwise all the way in.
Turn on cold water supply to the sink faucet and check for leaks.

Drilling the hole for the faucet
NOTE: Safety glasses should be worn to protect your eyes while drilling the faucet hole.
1. For best results, a ½” carbide-tipped drill bit should be used to drill a hole into your sink for the
auxiliary faucet.
2. Carefully select the faucet location making sure it will have a neat water fall pattern and that
the faucet stud will be accessible from below once the hole is completed.
3. For Porcelain Sink: Before starting the drill motor, apply firm downward pressure on the bit until
a crunching occurs. This will help keep the drill bit from moving.
4. For Stainless Steel Sink: Before using a ½” carbide drill bit, an indent should be made with a
center punch to keep the drill bit from moving. A small pilot hole will also aid the ½” drill bit.
5. For best results, keep steady firm pressure during the start of the hole will cause excess wear
on the bit and progress will be slow.
6. Once the hole is complete, clean the area of metal chips and roughness around the hole.
Metal chips will stain Porcelain.

Positioning the system
1. The head assembly will stand up in the sink cabinet or can be hung on screws provided.
2. The storage tank may be laid on its side.
3. The head assembly and/or storage tank maybe placed up to 15 feet from the point of use
with nominal pressure loss.
Fig. #10
CONNECTING THE SYSTEM
Use the color coded tubing to make the following connections:
• The white tubing connects the water supply adapter to the inlet side.
• The blue tubing connects the faucet to the outlet side.
• The Black tubing connects to the drain clamps.
• Tha yellow tubing connects the storage tank to the inlet side of the post
carbon.

START-UP PROCEDURE
1. Check to see all connections are made
2. Check that the pre-filter and pre-carbon sumps are secure using the housing wrench provided.
3. Slowly turn on the water by turning the needle valve counterclockwise.
4. The valve handle on top of the tank should be in the open position, parallel to the valve body
5. The handle of the faucet should be perpendicular to the spigot (closed).
6. Check for leaks.
7. The RO/NF ro drinking water system makes 2 gallons of drinking water per hour and requires
1 to 2 hours before water is readily available.
8. During this initial fill period, you will hear water being discharged through the black drain line.
This is normal as the contaminated water is being rejected by the reverse osmosis membrane.
DO NOT DRINK THE WATER FROM THE FIRST TANK PRODUCED BY THE SYSTEM.
DISCHARGE THE WATER FROM THE STORAGE TANK BY OPENING THE FAUCET.
DISCHARGING MIGHT TAKE UP TO 15 MINUTES.
If you have any difficulties with the installation, or require additional information on your unit,
please consult with our factory technicians.
We thank you for purchasing our Reverse Osmosis / Nanofiltration unit for your high quality processed drinking
water. In order to maintain this high quality water, it is important that scheduled maintenance be followed.
RECOMMENDED SYSTEM MAINTENANCE
To properly maintain your WECO drinking water system, please use
only genuine WECO water replacement filters at
www.wecofilters.com or call us at 1 (888) 675-5187

TINY Manual
Sediment Pre-filter: The pre-filter protects the system and should be
maintained regularly, a clear housing has been provided for your
convenience. The show-white pre-Filter should be changed when the
outside discolors to a cardboard brown color and before the inner
surface discolors. The life of the pre- filter will depend upon the
condition of your water supply and should be checked at 3-month
intervals until a filter life is established (average life 6 months).
Carbon Block: Designed to remove chlorine form the water supply, as
well as organic and inorganic substance before entering the TFC
membrane (average life 12 months).
Post-Carbon: The post-filter should be changed
when you experience an unusual taste and/or
odor to the water and has a nominal life of
1 year.
Membrane: The high quality Thin Film
Composite membrane should last between
2 to 4 years depending on the quality of your
local water.
Drain your storage tank twice each month to extend the membrane and have the freshest water
in the storage tank. Drain the storage tank by lifting the faucet handle into the parallel position
with the spigot until water flow stops from the tank. Return the faucet handle to the closed position
and the tank will refill in 2 hours. It is best to drain the system before retiring for the evening.

CHANGING THE PRE-FILTERS
1. Turn OFF cold water supply to RO system. Turn OFF tank’s ball-valve. Lift up RO faucet lever
briefly to relief the built-up pressure inside the RO system. This will make opening the housings
easier.
2. Open housing: Have the RO standing upright. Slip the plastic wrench onto the #1 housing.
Looking down from a top view, you should open the housing turning clockwise. If necessary,
lay RO down on the floor to get a better leverage. If the housing is too tight, use a hammer
and tap on the wrench handle to help turn the wrench.
3. Discard 3 used filters, wash housings with mild soap, rinse off. Put 3 new filters into their
respective housings: sediment filter in stage-1, carbon block filters in stages 2 & 3.
4. Close up the housings. Make sure each housing has a black O-ring in the thread groves. Use
wrench to tighten each housing.
5. Remember: Turn ON the cold water supply and OPEN the tank valve after finished changing
filters!

6. Check for leaks!
CHANGING THE MEMBRANE
CAUTION: ANY REPLACEMENT FILTERS OR MEMBRANE NOT RECOMMENDED BY THE
FACTORY CAN CAUSE SEVERE DAMAGE TO THE SYSTEM AND VOIDS ALL WARRANTIES.
1. Shut off the feed water to the system by turning the saddle valve on the water supply adapter
clockwise until it stops.
2. Close the storage tank ball valve by turning the handle perpendicular to the valve body.
3. Open the drinking water faucet relive pressure.
4. Allow 3-5 minutes for pressure in the system to drop.
5. Disconnect the tubing from the membrane cap by pushing in and holding down the end
collar ring surrounding the quick connect elbow fitting while gently pulling back on the tubing.
6. Remove the membrane housing cap by turning counter-clockwise.
7. Using a pair of needle nose pliers, remove and discard the used membrane.
8. Rinse the inside of membrane housing with warm water.
9. Using pliers, insert the new membrane all the way into the housing (double o-ring end first),
making sure it is properly seated.
10. Replace and hand-tighten the membrane housing cap by turning clockwise.
11. Reconnect the removed tubing by pushing it into the elbow fitting in the housing cap.
12. Gently pull back on the tubing to insure a leak free connection.
