Pressurization:
1. Confirm that pump bypass on the HDI is OPEN.
2. With the HDI bypass open, slowly OPEN the main bypass before the pre-filter so water flows through the tank and
then to the house.
3. Open air relief valve and open a tap in the hose to allow the air to escape. Run at least 10 gallons from the tap.
4. Fill tank slowly.
5. Once pressurized, confirm that there are no leaks at the fittings/connectors/system/tank top and bottom, pre-filter,
or post-filter.
6. If no leaks, connect the electrical cord to the system and turn on the power switch.
7.
IMPORTANT:
If a leak is observed, bypass the system (actuate main bypass), depressurize the system using the
blue button (reset button) on the right. Hold the button until a click is heard which is opening of the reject solenoid.
Re-press the button to stop the depressurizing action.
8. Once observed leaks are fixed, pressurize the system and recheck for leaks on fixed locations.
