• Mount the drain on the lower outlet of the tank as shown in the picture. Ensure that you
remember the gaskets, otherwise water loss may result (fig. 2).
• Mount the tank with the bayonet lock on the base plate. Important: Turn the tank so that the
drain is on the opposite side of the pump to prevent the pump from flooding later on.
• Place the main pipe in the centre of the tank on the ground as shown in the image (fig. 3).
• To fill in the sand, insert the funnel supplied onto the main pipe. Important: No sand must fall
into the main pipe! Enough space must be left in the upper part of the tank to ensure water
circulation. Regardless of weight, which may vary depending on the sand, do not fill any higher
than the top ring of the tank (fig. 4).
• After filling, carefully remove the funnel and clean the top edge of the tank. There must be no
sand on it, otherwise pressure loss in the tank may occur and the cleaning performance will be
impaired (fig. 5).
• Fix the valve head to the tank using the two halves of the clamp, the two long screws and the
matching O-ring and ensure that the connection is watertight. Important: The “PUMP” valve
opening must point towards the pump, since this is where the short capillary tube will be
connected in a later step (fig. 5-6).
• Mount the pressure gauge onto the valve head. To do this, remove any existing sealing cap
(fig. 6).
• Use the capillary tube to connect the upper outlet of the pump to the “PUMP” inlet of the
control valve and seal it securely using hose clamps and sealing rings (fig. 5-6).
• Important: Ensure that the locking flange and the sealing ring are mounted correctly (fig. 6)
The principle of sand filtration / connection to the pool (Graphic page 4)
Water from the pool (1) flows through the pump (2) to the inlet of the control valve (3). While the
water flows through the sand, dirt and deposits are retained in the filter container, and the cleaned
water flows back into the pool through the valve outlet (4). Some models also offer an outlet (5)
to the channel (6), e.g. for use with a vacuum pool cleaner or for emptying the pool.
Two different types are available:
With skimmer: Water from the pool skimmer (1) flows to the front connection of the pump (2). The
upper connection of the pump leads to the inlet (3) of the filter. The cleaned water flows back into
the pool via the filter outlet (4).
Without skimmer: If you do not have a skimmer, the supply line to the pump (2) must be hooked
directly into the pool. Take care not to suspend the hose too deep into the pool, as coarse soil
debris must NOT get into the filter system. A vacuum pool cleaner must be used to clean the floor.
The sand filter system would be damaged. Some models also feature a drain connection (5) for
use with a vacuum pool cleaner or for emptying the pool. The water escapes into the channel (6).
Please observe the local regulations; chlorine water must not simply be released into the
environment.
USING THE APPLIANCE FOR THE FIRST TIME
1. Check all connections to ensure a firm and watertight fit.
2. When the system is switched off, set the controller to BACKWASH. Warning Never turn or
press on the valve using momentum or excessive force.
3. Turn on the power and fill the system with water. All air vents must drain the air from the
system as fully as possible. The less air gets “trapped” in the system, the more thoroughly the
system will clean. Please refer also to the instructions in the pump manual. Neither the pump
nor the filter tank may contain any air. Alongside the loss of power, the air may become a
