MAINTENANCE OF THE HDC DEVICE:

The HDC Device requires no regular or scheduled maintenance at all! It contains no moving parts and is constructed of Poly Vinyl Chloride (PVC Plumbing). The HDC Device has no filter(s), it uses no chemicals, and requires no electrical supply nor grounding due to the lack of metal parts.

The HDC Water Device comes with 2 Schedule 40 unions that we recommend installing on to each side of The HDC Device to enable easy removal, inspection, or cleaning if something gets through the filtration system and o clock the HDC Device. In the unlikely event, The HDC Device is clogged for any reason, you would turn the pump off (and lock it out) then loosen the unions, flip The HDC Device 180 degrees and run the water through it backward for 5 minutes to dislodge debris. Then you may reinstall the unit back as it was.

WARNING:

Turn off and lock out the pool pump! When working with PVC cement, follow manufacturers' use instructions and recommendations. Be sure to avoid heat and flame and ensure proper ventilation when working with PVC primer/cement. The HDC Device must be the last component in the water treatment and circulation loop (i.e. after the pump, filter, heater, , chemical feeder, etc.) and it must be installed closest to the water return of the pool. If the return line is too short to accommodate The HDC Device, use elbows and additional PVC lengths to create the space. The HDCD Device should only be installed by a qualified professional. The HDC Device must be installed on the system return line. The HDC Device works at any angle; horizontal, vertical, or diagonal, as gravity has no effect upon The HDC Device. Remove the HDC Device from its packaging. Check the IN and OUT water flow direction as per the label. Inspect the contents, including the Schedule 40 unions (using PVC Primer and Cement as per the solvent cement manufacturer's instructions) onto The HDC Device with the unions. Be smart and efficient - measure twice, cut once.
