Main downpipe valve adjustment
To raise the water level in the overflow box, rotate the valve clockwise.To
lower the water level in the overflow box, rotate the valve counter clockwise.
The main downpipe flow valve provides a very fine control of the flow
rate however after making adjustments it takes the system a few
minutes to stabilize at the new setting.
Once you have established the approximate setting for the valve make
very small adjustments and wait for a few minutes each time. It may
take a number of occasional adjustments to reach a stable level. When
set properly this system removes all of the noise of water flowing down
to the sump.
ATO
On initial set-up, wait until the saltwater system is stable before using
the ATO. Ensure that the top-up flow valve is fully closed.
Fill the top-up reservoir with RO water. Disconnect the top-up flow valve
from the float valve and slowly open the flow valve until the top-up
water drips at a rate of approximately 1 drop per second. Reconnect the
flow valve to the float valve.
Adjust the angle of the float so that the valve is closed when the water
level is above the inlet of the pump but below the top of the bubble trap.
Power-out test
After completing the initial set up and after adding any new equipment
to the sump, make any adjustments necessary to the main valve to
stabilise the system and perform a “power-out” test to check that water
does not rise above the rim of the sump.
6 Maintenance
For continuous smooth operation of the water management system make
regular checks of the following:
• Water level in the overflow box - adjust the flow valve as required
• Water level in the reservoir – top up with RO water as required
• Water level in the sump, check that the top-up float valve is
operating correctly
• Micron Filter Bags – check that water is flowing through the bags
and clean/replace as required
• Surface skimmer combs – remove any deposits that reduce water flow
• Pump outlet nozzle – check for blockages and build-up of algae
Micron Filter bags
It is recommended to have at least 3 sets of filter bags.
There are a few options for cleaning the filter bags:
Quick and effective – Spray the outside of the bags with a powerful
water jet such as a garden hose to back-flush the detritus from the
Polyester bag.
More thorough – soak the bags in bleach or diluted vinegar for 24 hours
prior to spraying as above. Rinse well to remove all chemicals before
returning to sump.
The filter bags can also be put in a cold wash in a washing machine with regular
detergent or with vinegar (may require approval from a higher authority).
NOTE: It is recommended to close the valve on the outlet of the
reservoir whenever doing maintenance in the sump
