Installation instructions:
1. Before casting, mask off the skimmer´s opening to avoid any concrete
splashes. A casting attachment (item no. 112900) is available as an
accessory. This stabilizes the position of the skimmer in the concrete.
2. Fit the skimmer to the moulding using the attachment clamps on the flange.
The skimmer´s sealing flange shall be at the centre of the moulding and
the water surface shall be at the centre of the opening. The pool wall is then
chamfered at 45° to the skimmer. (See sketch)
3. Connect the pipe connection using a suitable thread seal.
4. The collar is adapted to the floor covering around the pool and is secured
with the brackets supplied.
5. 5. Fit the inlet gate in the skimmer after casting.
