Pump Set Up (contd.)
4. Pump Speed - Fine Setting:
This setting is required to fine tune the speed at
flow rates other than that used to set the main flow
rate.

a. 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 by
pressing the OK '
Note: For pumped showers 2ltr increments may not be
possible. Use the selections on the shower.
b. Repeat the above process. The narrow
adjustment corrects the flow rate over a band 1
ltr/min either side of the flow rate that is being
calibrated.
When the maximum flow rate is set then proceed
to the next setting by pressing the '>' key.

5. Pump Shut Down:
Over Run (Auto-Sense) Preferred Option
Auto-Sense operates by recognising when the
pump is drawing air through the pump (after waste
water is removed from the tray). This is done by
recording the lowest current taken by the pump as
a limit value. In subsequent shower operations
when this value is reached the pump turns off.

When the pump has removed the water remaining
in the tray the pump current will decrease. When it
has reached the lowest value (by observing when
the value stops falling) press OK '
store this value.
Over Run (Time-Delay)
Alternatively to set a fixed Over Run delay select
Time-Delay.

6. Start Volume:
This selects the initial amount of water (litres) in
the tray before pumping starts. To minimise noise
the water should be above the level of the gulley.

(Factory default is the minimum setting of
0.6 ltrs). Pressing the up arrow will increase the
amount of water from 0.6 ltrs to 4 ltrs passing
through the shower head before the pump starts.
Make this adjustment during final commissioning.
