Filtration Unit - Martinic QS 500, on a pallet with INVERPro IP25 WiFi Pump 26 m3 / h, with Praher 6-Way Valve

The high-quality Martinic QS sand filtration system is the ideal solution for effective mechanical cleaning and keeping your pool water crystal clear. The entire filtration system is built on a stable base plate, to which the robust Martinic polypropylene tank is firmly bolted. In its design, the manufacturer placed great emphasis on user comfort and easy maintenance. The tank opens exactly in the middle, which significantly simplifies, speeds up, and makes periodic replacement of the filter sand or modern glass media easier. Maximum tightness, strength, and safety of this split body are ensured by a robust steel clamp ring, which firmly connects the upper and lower parts of the tank and easily withstands water pressure.
This filtration set is completed by a top-quality, bolted 6-way valve from the renowned Praher brand, which serves as the control center of the entire filtration system. Using the ergonomic control lever, you can easily switch between six different modes according to your pool’s current needs. In addition to the standard filtration mode, where water passes through the sand bed and is cleaned of impurities, the valve allows you to start backwashing to clean the filter media itself and then perform a rinse cycle to settle the filter media back in place. You can also use the circulation mode for quickly mixing pool chemicals without the water passing through the filter, the full drain mode for discharging water to waste (suitable, for example, when vacuuming coarse dirt from the bottom or when winterizing the pool), and last but not least, the “closed” position, which completely shuts off water flow and is especially useful when servicing and cleaning the pump. Martinic QS combines long service life, high efficiency, and exceptionally easy operation in one package.

Valve Positions and Their Functions

The valve positions are as follows:

Pool filtration: Water is drawn from the skimmer or bottom drain, passes through the filtration system where it is cleaned, and then returns to the pool through the return jets.
Backwash cycle: The filter media (sand) is cleaned, while the dirty water is discharged to waste.
Rinse after backwash: Used to remove fine dirt left after backwashing.
Draining water from the pool: If the pool is equipped with a bottom drain, it can be completely drained.
Circulation bypassing the filter tank: Water bypasses the filtration system, suitable for example when priming the pump.
Closing the entire circulation system: Used to shut off the system during maintenance or when cleaning the pump prefilter.
