Pumping flow rate:
Pump speed settings
Prior to making adjustments turn the
shower on and wait till the pump runs.
Set the shower flow rate to 8 ltrs/min.
Watch the level of water within the shower
using the gulley cover as a guide. If the water
level is lowering then reduce the speed of the
pump by pressing the Down arrow. Use initial
increments of 5 until fine tuning is required.
When the water level is rising then increase
the speed of the pump by using the
Up arrow.
After making a change watch the water level.
Wait at least 30 seconds, as the system
needs to stabilise, until you see if the water is
rising or falling. When the water level is
slightly over pumping, program in the speed
setting by pressing the Mode button firmly
until the LED blinks

Pump speed – Narrow setting
This setting is required for higher flow rates.
a.
'Pump speed' must be set first as per
above using a mid-range flow setting.
b.
Increase the flow from the shower in
increments of 2 litres and watch the
water level around the shower gulley. If
this is rising or falling over time make
adjustments until a constant level is
observed then programme in the
setting.
c.
This process is repeated in 2 ltr
increments. The narrow adjustment
corrects the flow rate over a band 1
ltr/min either side of the flow rate that is
being calibrated.

Pump shut down:-
Over Run (Auto Sense) preferred option
To set Auto Sense Over Run (indicated by
'AS' on the LED) you must turn off the
shower when you have selected this mode.
When the pump is drawing air there will be a
gurgling noise at the gulley, press down the
Mode button so the controller stores the
loading on the pump at this point.
Over Run (Fixed)
Alternatively to set a fixed Over Run delay
use the Up and Down arrows. Each digit
represents a delay of 5 seconds
(i.e. 2 =10 seconds over run).
Hold the Mode button down to program.
Commissioning Checklist
a.
All push fit fittings must have the twist
lock in the locked position.
b.
Check all plumbing for leaks.
c.
Check waste water plumbing for leaks
while pump is running.
d.
Ensure flow sensor is unstressed.
After programming all the settings, turn the
shower on and check for correct operation.
Make final adjustment to the Start Delay if
required.
Note: 15 minutes after showering is finished, the
pump will switch on for a brief period in order to
remove any water that may have pooled.
