500L RO/DI system with a manual reel: setup guide

This configuration combines a 500-litre tank, reverse-osmosis and DI treatment, and a manual reel for one operator. RO reduces dissolved solids in the feed water; DI resin then polishes the output.

That treatment is intended for the cleaning application. It should not be described as disinfection or a guarantee that water is safe to drink. The result on glass also depends on technique, rinsing and surface condition.

Confirm the chosen hose, battery, charging and accessories in the current configuration summary.

A 500-litre tank does not mean the filtration system produces 500 litres immediately. Production depends on the equipment and feed conditions. Compare the required fill volume with the time available between rounds.

• Confirm the required feed pressure and flow.
• Allow for the RO reject-water stream and its appropriate disposal.
• Check pre-filter, membrane and resin servicing requirements.
• Measure the relevant outputs rather than assuming performance remains unchanged.

See RO versus DI for the running-cost questions to ask.

Five hundred litres of water weighs approximately 500kg before equipment and other loads. Confirm the exact vehicle’s available payload, axle limits and installation requirements.

Record real water use on a normal and busy day. If the tank is not sufficient, compare refill arrangements and a suitable alternative capacity; do not choose a larger tank without checking the complete vehicle load.

Check how the hose leaves the van and where you will stand to rewind it. Winding direction, clear handle access and compatible fittings are important details in daily use.

Read the current selected specification for pump, controller, electrical supply, hose, accessories and delivery or installation. A product photograph is useful context, but it is not a list of everything included.

Keep records of incoming water, RO output and final polished output where the setup allows those checks. A change in readings can help distinguish a treatment issue from contamination elsewhere in the system.

Follow the specified filter changes, membrane care and frost-protection instructions. Inspect the hose, reel and brush as part of the same routine. There is no fixed servicing interval that suits every water supply and workload.
