15 NOTE: Check the pressure on the pressure gauge while the sand filter is operating. Generally, when the pressure of the recommended sand filter pump is less than 0.2 bar
(3 psi) (green area), it runs normally. Note: Maintenance can only be performed after the sand filtration pump has been disconnected. Otherwise, serious personal injury or
even death may result. Note: While the sand filtration pump is running, record the reading on the pressure gauge. When the pressure gauge shows 0.2 bar (3 psi) or higher, clean the sand bed or replace the sand. Use the “backwash” and “rinse” functions. Note: depending on the specific application, we recommend periodic flushing.

Long-term storage and winter storage

Use of the product in a frozen pool may cause damage and void the warranty quality. If the product is to be used with antifreeze, propylene glycol may also be used. Propylene glycol is a non-toxic chemical that will not damage any plastic parts. Other types of antifreeze are highly toxic and can be harmful to the plastic components of the product.

Before draining water or changing the location of the pool, make sure the direction of discharge is toward the drainage ditch and away from the house. Familiarize yourself with local regulations and special water treatment requirements.
Switch off the product and disconnect the power plug.
After emptying, remove all connected sand filtration pumps, notched pipes and filter covers on the pool wall.
Unscrew the drain valve (8) counterclockwise to completely drain the water from the filter. The drain plug is at the bottom of the filter body.
Dry the sand filtration pump components and the knurled pipes.
Before long-term storage, lubricate the sealing rings and washers in the order listed below.
The best practice for product storage is to dry the parts and engine and put them in their original packaging. To avoid shrinkage or corrosion, do not cover or wrap the motor in a plastic bag.
Store the motor and components in a dry place at a temperature between 0 °C and 40 °C.
