INSTALLATION START-UP AND FIRST USE
- Turn-off water mains
- Avoid all kind of tension by using original wall brackets as a support
- The installation of a bypass is recommended.
- Connect the inlet to the product’s side with the indication IN and the outlet to the side with the indication OUT.
- Connect to pipes using cylindrical (parallel) fittings or US conical (tapered) fittings, possibly with flexible hoses.
- Use only sealing tape as a sealant for the connections.
- If the product is supplied without cartridge/s, unscrew the housing bowl from the head and insert the cartridge/s, lubricate the o-ring., then screw the bowl to the head and tighten with original spanners.
- Turn on the water mains.
- Unscrew the vent valve and wait for the air purge, then screw and tighten the vent valve. After installation, slowly turn on a water supply (tap) downstream of the installed unit and let the water flow for at least 5 minutes to flush the system before use.
WARNING:
Make sure that there are no water leaks from the product, and ensure you
control the tightening between the housing head and the housing bowl. Continue
checking that the tightening is good and there is no water leakage for 48
hours following the Installation and start-up. In case of leakage, open the
housing, remove the o-ring from the bowl, place a new o-ring, and apply
lubricant, then re-tighten the bowl to the head and repeat the leakage check
as above.

goal.
The Rain Harvesting approach to rainwater collection involves using tested and proven products to make quality rainwater available for use in and around your property. You don’t need much to get started and you will be surprised how easy it is to get the most out of your rainwater system.
