Replacement of sand
Open the drain and let the water flow out. Remove the sand. This can be done by means of the vacuum system "Sandvak", which can
be connected to the main water supply just like a garden hose. The filter can also be emptied by hand.
Triton® : To replace the sand, turn the top diffuser system to the side. The thread of the filter should be protected, in the same way
as with filling.
Take care not to damage the bottom laterals.
The sand in the filter must be changed every 5 years.
Winterizing
In areas that have freezing winter temperatures protect pool equipment. The filter, pump and pipelines must be emptied to protect
them from freezing. To do this move the valve handle to the "Backwash" position, open drain tap with hose connection end 180° to
the left (do not unscrew) and open the bleed valve. Open all valves. A small flexible piece of tubing can be attached to the drain tap.
Allow filter, pump and pipelines to drain completely
