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
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.
Switch settings
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
The cycle time should be set taking into account
customer requirements and water regulations on the
amount of water used. A 30 minute cycle caters for
most users; 20 minutes recommended for schools
and hospitals.
3 Off
= disable manual flush button
3 On
= enable manual flush button
4 Off
= standard sensitivity detector
4 On
= low sensitivity detector
manual flush
button is hidden below the dolphin's tail
on the front of the unit. (see diagram overleaf)
Switch on to reduce movement detection range and
sensitivity. Recommended if scent spray is nearby.
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
SET
button, tap the external hidden
Manual Flush
button,
then release
SET
button. The red light flashes every 2 seconds; the number of flashes shows the
maintenance flush setting. Each press of the
SET
button changes to the next setting, as follows :-
1 flash = No maintenance flush
2 flashes = 8 hour interval
3 flashes = 12 hour interval, (factory setting)
4 flashes = 24 hour interval
When desired setting is shown, press
Manual Flush
button to save setting. Switch on switch 3.
