SPRINGWELL SMARTFLUSH SF4M FITTING INSTRUCTIONS
Pack contains: sensing/control unit for 230V power; low-voltage latching valve (as supplied could be
open or closed), assembled valve cable with gland and connector; clips, screws, wallplugs.
How Smartflush works
Smartflush stands by until movement is detected, then waits before filling and flushing the cistern
Cycle of operation
Installation
THIS UNIT MUST BE FITTED ONLY BY A COMPETENT ELECTRICIAN
1) Fit back box of control unit on the wall or ceiling where it can be seen.
2) Fit valve : Ensure that there is an isolating valve in the feed to the new valve (to comply with
water regulations). Isolate water supply. Cut out 30mm of pipe feeding cistern and fit valve, with coil
not below centre line of pipe. Direction is IMPORTANT; Valve is marked 'IN' for inlet. Fully open
any existing trickle cock except for very hard water, when a partly open cock avoids excessive wear.
3) Fit cable and gland to box. (If too short, replace with longer similar cable, polarity important).
4) Set internal switches 1 and 2 which adjust the cycle time, i.e. the time from detection to end of
flush. (see diagram above) and ensure switch 3 is on.
1 Off & 2 off = 20 minute cycle
1 On & 2 off = 30 minute cycle (default)
1 Off & 2 on = 40 minute cycle
1 On & 2 on = 60 minute cycle
3 Off = disable manual flush button
3 On = enable manual flush button
4 Off = standard sensitivity detector
4 On = low sensitivity detector
5) Use 3-core flex to connect via a 1A fused spur to connections marked N (neutral), E (earth) and
L (live). Seal entry hole with a cable gland so that the unit is watertight. Plug in valve. Power on;
the red light on the power board should light. Press manual flush button a few times to confirm
operation of the valve, sharp click with red flash in the lens for "on", dull click with no flash for "off".
Leave valve closed. N.B. As supplied, the valve might be latched open or closed, this is normal.
6) Turn on water with isolating valve fully open. Smartflush is factory pre-set to activate a
maintenance flush at 12 hour intervals if no-one is seen. Go to step 7 if this setting is okay.
Switch off switch 3. Hold down internal
