Backorder & Dispatch Timeline

This item is stocked to order. Back-orders are consolidated and placed with our overseas suppliers once a month, on the last day of the month, and all such orders are shipped before the 15th of the following month.

Back-orders cannot be cancelled once they have been placed with the supplier. If you cancel before that, payment-gateway charges of 2% plus GST are deducted and the balance refunded. In the rare case a supplier cannot fulfil the item, we will offer you an alternative first, and refund in full with no deduction if you would rather not take it.

Setup & Use

Place the DDR under the tank. It holds fluids for a DOS in two separate 2 L cylinders, 4 L in all. Each cylinder pairs with one DOS pump, joined with push fit tubing. The box has 4 m of tubing and the sensor cable. The optical level sensors report to Apex Fusion, so you need an Apex with a DOS for level alerts.
