1. Sierra unit and tank are located where they will not be subject to physical impacts or rough contact
by heavy objects.
2. Feed water pressure to the unit is no less than 40 psi and no greater than 80 PSI.
3. Ensure the plastic retainer clips are fully engaged. The slide locks must snap into place in the slots.
If the clip does not snap easily into place through the slots it means the cartridge is not fully inserted
into the connectors. Press top or bottom of cartridge to engage connectors until it snaps into place
properly.
4. All tubing connections, especially push-in quick connections, are fully inserted.
5. Tubing connected between the faucet and the drain saddle fitting (the fitting attached to the sink
drain pipe) runs "downhill" to the drain. There should be no loops or places where water would not
flow out to the drain.
6. Feed and tank valves are open.
7. Within one to two hours after initial application of water pressure, check again for leaks especially
at the tank, faucet tubing and connectors. These parts will not see full pressure until approximately
2 hours after the system is activated.
8. Flush three tankfuls of product water to drain. If a chlorine scent persists, repeat flushing
procedure in Section 8.
