Your new Hayward Thru-Wall Skimmer makes pool maintenance easier and more convenient. Leaves, insects and
floating debris are pulled from the pool into the skimmer basket. Clean the basket regularly to keep your pool
sparkling clean and sanitary.
POOL PREPARATION
Fill the pool with approximately two (2) feet of water so the liner is under weight and stretched to the proper position prior to installing the
skimmer. Note: The liner cannot be shifted after the skimmer and return holes have been cut.
SKIMMER ASSEMBY
1. If the SP1091E, Wide mouth extension, is not installed on the body, it must be assembled to the body prior to attempting to install
the skimmer in the pool.
2. To install the wide mouth extension, insert four (4) pan head screws 1” long through the lip of the extension and four (4) through
the throat of the skimmer. Place the gasket between the extension and the skimmer body. Firmly tighten the screws.
SKIMMER INSTALLATION
1. From the outside of the pool install the face-plate double gasket at skimmer cutout in the wall. Reach over the top rail of the pool
and carefully press the face-plate and liner against the gasket and skimmer cutout in the wall. Punch out the two top corner holes
using a blunt object. Insert two self-threading flat head screws (provided) into the top corner holes of the face-plate.
2. Carefully push the screws through the holes that have been pierced in the liner and through the double gasket. From the outside
of the pool, align the skimmer body with these screws. Lightly tighten the two screws.
3. Using a blunt object, pierce the remaining holes in the liner. Insert and lightly tighten the remaining flat head screws through the
face-plate, liner, gasket and into the corresponding holes on the skimmer. Firmly tighten all screws evenly, alternately left and
right, top and bottom.
4. Using the skimmer face plate as a guide, use a razor knife to trim only the liner, being careful not to the gasket, in the large
skimmer opening.
