8 Easy Installation Steps

1. Since the three chamber Hydra systems are gravity fed, a 4" bottom drain is included and should be in place before chambers are installed.
2. A hard, level surface must be prepared for the chambers. Your piping from the bottom drain should be already set up and ready to connect. Use 4" coupling and PVC piping to do this. PVC joints will be required to carry water from the drain level to the entrance into the vortex chamber.
3. Remember-the tops of your filters need to be at pond level, so you will probably need to set up a sump area for waste drainage from the vortex and brush chambers. If your filter will be underground, dig deeper than you think you will need. It's easier to fill in a hole than to make it deeper.
4. Use a marker to trace the black PVC connector, including the screw holes. Using a 5" hole saw for the Hydra 4000 and a 4-1/2" hole saw for the Hydra 2500 carefully cut holes in chamber. A 2.5" hole saw should be used for drain holes in the brush and vortex chambers. Use a 9 / 64" drill bit to drill holes for the screws.
5. Attach the PVC connectors, using a silicon sealant to prevent leaks. "Male" end goes on the outside of the chamber. Metric to U.S. adapter goes on the male connector. All of the attachments should be connected using a sealant. Test fit before gluing.
6. A stop valve or gate valve should be placed where the drain and vortex chamber meet. This allows water flow to be stopped during cleaning. Do not connect the valve directly to the chamber in case it needs to be raised or lowered later.
7. Between the brush chamber and the biological chamber two 90 degree elbows connected by PVC pipe, are required to carry the water from the bottom of the brush chamber to the top of the biological chamber.
8. For the Hydra 4000 a Sequence 1000-1 / 4 Hp pump is recommended unless the water needs to go through an accessory such as a fountain or waterfall, in which case a higher Hp pump may be needed. For the Hydra 2500 a Sequence 1000 1/6 Hp is recommended.

Caution: When using any sealant, make sure that your fittings and connectors fit together before applying glue. Failure to do so may result in improper fittings and wasted materials.
