FITTING INSTRUCTIONS:

Fitting The Pre-Plumbed RO System

Use the bracket as a template to mark the position of the unit on a suitable wall or cupboard panel. Allow a minimum
of 40mm clearance below the filter bowls to allow for filter change out. Drill and plug two holes and screw in 2

screws (not supplied) allowing the screw heads to protrude from the wall by approx.
5mm. Place the bracket over the screws and slide to left or right (as preferred) to lock
bracket in position.

Fitting The Tap

Select a suitable position on the work top or corner of the sink. Before drilling the

hole, check there is nothing directly underneath that could be damaged i.e.
water or waste pipes, cables etc. Also make sure that there is room for the
locating washer and that you can physically reach the tap stud to connect the

brass nut. Use a centre punch to mark the location of the hole to be drilled. Drill

a 3mm pilot hole. Enlarge the hole to 11mm. If you are drilling through
stainless steel, deburr and rough edges around the hole. Wipe clean with a soft
cloth. Check that the tap stud fits easily through the hole. Secure the push fit

connector and firmly push one end of the blue pipe into the collar within the

push-fit connector. Push the other end of the blue tubing into the push fit
connector fitted to the post carbon filter housing.Note: Some taps are supplied
with the blue tubing already permanently fitted. The tap has two ‘ON’

positions. Lift the lever up for continuous flow. Press the lever down for flow
that ceases when the lever is released.

Fitting The Saddle Tapping Valve

Although not essential, we recommend that you turn off the cold water stopcock
and relieve the water pressure by opening cold water tap. If the stopcock is under
the sink, fit the valve after the stopcock. The valve must be fitted on the cold
water supply only, (if you are uncertain, run the hot tap for a minute and feel the
pipes under the sink to distinguish the cold pipe).
Do not fit the valve on a bend, a join or where there is solder on the copper pipe.
Attach the clamp around the pipe and tighten the clamp bolt to ensure a water
tight seal. Do not over tighten the clamp bolt as this may distort the water pipe.
Firmly push the open end of the red tubing attached to the saddle tapping valve
into the collar on the front of the pre carbon filter housing.
Note: Later designs have the red tubing already permanently fitted to the valve.
The saddle tapping valve supplied with the RO-Pro System is designed to comply
with British plumbing codes. (See ‘System Start Up’ Section for further details
regarding the saddle tapping valve.) Note: Later designs have the red tubing already permanently fitted to the

valve. The saddle tapping valve supplied with the RO-Pro System is designed to comply with British plumbing codes.

Fitting The Tank Ball Valve

Remove the plastic cap on the top of the tank. Wrap the thread 3 or 4 times with plumbers tape (Teflon). Connect
the ball valve to the thread and make sure it is tight but not over-tight. Connect the yellow tubing to the tank ball
valve. Turn the tank ball valve off. Note: Do not tamper with the air valve on the low side of the storage tank. It has
been preset at 8-10 psi by the manufacturers.

Mounting The Drain Clamp

Position the drain saddle in the desired location (please see notes below), mark spot through thread outlet, remove
saddle. Drill 1/4” (6.3mm) hole into the drain pipe above the water line of the trap/U-bend. Fix self adhesive foam
seal over the hole in the drain saddle ensuring that the holes line up. Align the hole drilled in the drain pipe with the
drain saddle using a drill bit. Make sure to align drain saddle to drilled hole. Attach drain saddle to drain pipe and
tighten the two screws evenly. Connect the black tubing to the drain clamp.
Note: The drain clamp will fit most standard drain pipe 1 1/2” diameter. It should be installed above the trap/u-bend
and on the vertical or horizontal tailpiece. If a waste disposal unit is fitted, the drain clamp must not be fitted into the
same waste pipe.

SYSTEM START UP:

Turn on the cold water supply at the stopcock and turn the cross piece on the saddle tap valve anti-clockwise

to open. Close the tank ball valve. Open the tap for continuous flow (Lever Up). Check the system for leaks,

tighten as necessary. After 10-30 minutes, water will start to drip out of the tap. Let it drip for about 10

minutes and then flip the tap handle to the closed position. TURN ON THE TANK BALL VALVE NOW.

It may now take several hours for the storage tank to fill, depending on the local water pressure.

Note: DO NOT DRINK THE WATER FROM THE FIRST TANK PRODUCED BY YOUR NEWLY PURCHASED RO-PRO

SYSTEM.

After the tank is full (you will hear the water stop), flush the system by placing the tap in the open position

until all the water is completely discharged. Upon complete discharge of the storage tank, return the tap

handle to the closed position and let the refilling process begin. This process could take 2-3 hours to

complete. After the second tank is filled, you may enjoy the pure water. Check for leaks daily for the first

week and periodically thereafter. You may notice that the water may be milky coloured during the first

week. This is caused by air bubbles in the water released from the carbon filter, they will dissipate on

allowing to stand. It is normal and safe.

NOTE:

DO NOT USE WITH WATER THAT IS MICRO BIOLOGICALLY UNSAFE OR OF UNKNOWN QUALITY WITHOUT

ADEQUATE DISINFECTION BEFORE OR AFTER THE SYSTEM. SYSTEMS CERTIFIED FOR CYST REDUCTION MAY

BE USED ON DISINFECTED WATER THAT MAY CONTAIN FILTERABLE CYSTS.

THIS REVERSE OSMOSIS SYSTEM CONTAINS A REPLACEABLE COMPONENT CRITICAL TO THE EFFICIENCY OF

THE SYSTEM. REPLACEMENT OF THE REVERSE OSMOSIS COMPONENT SHOULD BE WITH ONE OF IDENTICAL

SPECIFICATIONS, AS DEFINED BY THE MANUFACTURER, TO ASSURE THE SAME EFFICIENCY AND

CONTAMINANT REDUCTION PERFORMANCE.

WARNING: DO NOT USE THIS RO-PRO SYSTEM TO PURIFY NON-DRINKABLE SOURCES OF WATER THAT
ARE UNSAFE OR WITH WATER OF UNKNOWN QUALITY/

WARNING: NEVER USE HOT WATER OR ALLOW THE UNIT TO FREEZE.

WARNING: INCORRECT INSTALLATION WILL VOID THE WARRANTY.

FILTER MAINTENANCE AND CHANGE INSTRUCTIONS:

This recommendation is intended for maximum efficiency of RO water production by your system.

1, Filter Maintenance
a, It is OK to put pre & post filters of the shelf for several years.
b, Keep the sealed, non-opened filter in an air tight container to prevent it from absorbing contaminants
from the air.

2, Membrane Maintenance
a, The dry packed membrane usually has a two-year shelf life. To prolong the shelf life, we recommend
you keep the non-opened dry membrane in the refrigerator.

b, Once used, we recommend you run the RO system every day, at least 10-15 minutes (about 1 gallon or 4

litres drinking water.) This helps to maintain the membrane performance.

c, If the RO system is not used for a few weeks, drain the storage tank. To bring the unit into service fill the

tank and drain it twice, to allow to refill. Your RO system will then be ready to reuse.

3, Filter & Membrane Change Procedures:
a, Shut off the water supply.
b, Turn off the tank ball valve by turning the handle through 90 degrees.
c, Open the tap fully for continuous flow.
d, Slide the housing wrench in (bowl spanner) over the filter bowl. Use one hand to hold the system and
the other hand to turn the wrench clockwise to separate the head from the bolw.

NOTE: IF IT IS TOO TIGHT TO OPEN THE HOUSING YOU MAY TRY TO UNPLUG THE FITTING

BETWEEN THE RED TUBING AND THE SYSTEMS IN ORDER TO REDUCE THE AIR AND WATER

PRESSURE INSIDE THE HOUSING.

e, After opening the housing, remove the used filter and put the new filter into the housing. The Carbon

Prefilter can be installed either way up. The blue GAC post filter must be installed the correct way up

with the white tapered cap to the top. Make sure the O-ring is in place and smear a little petroleum jelly
on the O-ring. Replace the filter bowl and tighten bu turning the bowl anti-clockwise.

f, Repeat previous step for all other filter changes. (See separate instructions for membrane change below.)

g, Turn on the water supply and make sure there are no leaks.

h, Let the water drip from the tap for about 10 minutes. If the water flow is less than 1 cup (8 oz or 240 ml)

per minute, it may be a signal to change the membrane.

i, Membrane Change Procedure:
Shut off water supply.
Unscrew the cap of the membrane housing.

Slide out the used membrane and discard. (You may need thin nosed pliers to grip the membrane spigot.)

Insert the new membrane with the 2 O-rings into housing first with the black brine seal at the open end
of the membrane housing.
Be sure it is fully seated into bottom end.
Screw cap back on to the membrane housing, make sure O-ring is still in place.
Turn on water supply & check for leaks.
It may take 10-20 minutes for new membrane to run to normal flow.

Carry out system start up procedure.
