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 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 (7/16”). 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. Place the nut and then the
plastic olive over the blue tube leaving 3-4mm of blue tube showing. Push tube insert into the open end of
the blue tube. Tighten the nut onto the end of the tap stud.
The tap is off when the lever is pointing down. Turn lever to the right for flow.
Fitting The Saddle Tapping Valve
(Red tubing attached)
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 copper pipe 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 sediment filter housing (Stage 1).
Note:
Later designs have the red tubing already permanently fitted to the valve. The saddle tapping valve
supplied with the Reverse Osmosis System is designed to comply with British plumbing codes. (See
‘System Start Up’ Section for further details regarding the saddle tapping valve.)
Fitting The Tank Ball Valve
Connect the ball valve to the threaded connector on the tank, make sure it is tight but not over-tight.
Connect the yellow tubing to the tank ball valve. Turn the tank ball valve off. ie handle at 90 degrees to the
tube.
Note:
The air valve on the lower side of the storage tank has been preset at 8-10 psi by the
manufacturers. In time it may need topping back up to pressure—see troubleshooting.
Mounting The Drain Clamp
Connect the red tubing to the output of the flow restrictor. Turn off the membrane flush valve.
Note:
The drain clamp will fit most standard drain pipe 1 1/2” diameter. It should be installed above the trap/
u-bend - between the sink and the 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. It is important that the drain is
NOT
connected into the foul side of the sink U Bend.
Position the drain saddle in the desired location by hand, mark a spot on the waste pipe through the tube
connector, remove saddle. Drill 1/4” (6.3mm) hole into the drain pipe above the water line of the trap/U-
bend. 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 self adhesive seal on the inside of the saddle over the drain hole. Attach drain
saddle to waste pipe and tighten the two screws evenly. Connect the red tubing to the drain push fit
connector.
