FIG 2
DRAIN CONNECTION
(black elbow under head)
• 2.5mtrs of white low pressure drain hose is supplied with the unit. This is to be used for both the
drain and overflow. The drain connection is the black barbed elbow under the rear top cover. To
remove rear top cover, simply slide forward out of fixing, and lift off. Fix drain hose to black barbed
elbow with jubilee clip (supplied).
• Run the drain hose to either an upstand or an outside drain. Connect the drain hose to the spigot
of the Air Gap provided to ensure a 20mm air gap existsat the end of the drain line.
• If you need to extend the drain hose, this can be done by connecting to a 15mm copper tube for a
maximum run of 4 metres, with a minimum daytime pressure of 40 psi. Over 4 metres please use
22mm (or similar) copper tube.
• Ensure that the drain hose is adequately fixed to the copper pipe.
• The drain hose must not dip or be kinked in any way, as this will lead to an overflow of the
machine.
• UPHILL? The white flexible drain hose can run uphill internally, for a maximum of 3 feet, with a
minimum water pressure of 40 psi.
• Softened water will have no adverse effect on a septic tank.
• Under no circumstances should the softener drain and overflow share the same pipe. This could
lead to foul smells entering the salt cabinet from the main drain via the overflow. Also if the
common drain ever gets blocked, the regen water can re-enter the softener via the overflow pipe.
/ L. OVERFLOW CONNECTION - IMPORTANT (White elbow connection on back of cabinet)
• The hose for the overflow should be cut from the white low pressure hose supplied with the unit.
• The overflow connection is the ½” hose spigot on the rear right hand corner of the cabinet – no
jubilee clip required.
• The overflow must be run downhill and terminate immediately through an outside wall without
kinks or restriction.
• A 22mm (or similar) copper protective sleeve through the Fig 1 outside wall will help prevent
kinking of the hose.
/ M. TEST INSTALLATION FOR LEAKS
Place the bypass handles in the horizontal Bypass position. Open mains stopcock slowly to flush the new
pipe work. This can be done using a ‘soft’ mains tap i.e. utility room cold tap or wash hand basin in a
bathroom. Check all connections for leaks.
/ J. INLET & OUTLET CONNECTIONS - See Fig 2
• Remove both salt lid and main cover to access inlet and
outlet connections.
• Remove grey retaining clips and also BSP connection
points. Connect hoses to male BSP connection points,
tighten to seal, then reinsert BSP connection points back
into valve body. Fit grey clips. The connection points are
designed to rotate once inserted in valve body. This
removes any stress/ pressure.
• We recommend you fit the elbow end of the hose to the
inlet/outlet connection points on the softener.
Under no circumstances use washing machines hoses or
plumb the softener in solid copper pipe.
