F-RO-4 Reverse Osmosis System I & O Manual
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 tap and blue tubing as shown in the diagram to
the left. Firmly push the lose end of the blue tubing into the push fit connector fitted
to the inline post carbon filter (Stage 4)
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. Note: Some taps are supplied with the blue tubing already permanently fitted.
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 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 F-RO-4 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
Remove the plastic cap on the top of the tank. Wrap the thread 3 or 4 times with plumbers tape (PTFE/Teflon).
Connect the ball valve to the thread and make sure it is tight but not over-tight. Connect the white 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. 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 orange 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.
