INSTALLATION INSTRUCTIONS:

1. Begin by assembling the wide mouth extension to the skimmer housing using (8) SS Philips Head screws and the 8946 Gasket. The eight holes are the ones that are

recessed in the extension piece.There are 2 holes on all four sides at the rear of the extension.

2. If pool wall IS factory pre-cut for a skimmer and return tting follow these instructions, otherwise go to step 3 below.

a. Locate the wall opening, and punch out the (22) twenty two 1 /4" holes, and rectangular cut out.

b. Find the pre-cut area for the return tting and knock out the cut out.

c.With a le or piece of sandpaper remove any metal burrs that may cut the liner or yourself during the assembly.

d. Skip step 3 and go directly to step 4.

3. If the pool wall is NOT factory pre-cut for a skimmer and return follow these instructions.

a. Using the Hole Template Guide, locate the area against the metal wall at your desired position. (The water level should be approximately at the mid point

of the face plate.) Be careful that the skimmer body and face plate will not interfere with the top coping or the lip of the pool structure.

b. Using the Hole Template Guide drawing for spacing details, drill (22) 1/4" holes.With a pair of tin snips cut a 5-5/8" x 12" opening in the wall, again using

the drawing as a guide.

c. Next, nd a desired location for the return tting.The cutout should be approximately 8" below the desired water level. Cut a 2-3/8" diameter circle at

the location.

d.With a le or piece of sandpaper remove any metal burrs that may cut the liner or yourself during assembly.

4. Skimmer Housing Installation procedure:

a. Select one of the 8905 hose adapters and screw into the bottom of the skimmer housing using theTeon tape. CAUTION: these are pipe threads and over

tightening can crack the housing. Never use any type of glue or sealant on these threads.

b. Place one of the 8917Wide Mouth skimmer gaskets on the skimmer face, making sure that the holes in the gasket align with the holes in the skimmer face.

c. Align the skimmer face and gasket with the drilled holes in the wall panel and fasten with (4) four pan head screws.These are the 4 short screws in the

hardware set.The holes are located on the top and bottom of the housing. They are the 3rd hole in from each side of the housing.

d. Install the vinyl liner according to the swimming pool manufacturer's instruction. Do not cut any holes in the liner at this time. Fill the pool to

approximately 2" below the return tting before proceeding to the next steps. Adjust the liner as necessary as pool is lling.

e. Align the second 8917 gasket and face plate (8918).

f.You should have a sandwich of materials between the face plate and the skimmer housing as follows: the 8918 Face plate, 8917 gasket, the vinyl liner, the

metal wall panel, 8917 gasket and nally the skimmer housingWide Mouth extension.

g. Fasten tightly to the skimmer face with the 18 remaining stainless steel Philips head screws. Alternate tightening screws from left to right and top to bottom.

h. Connect the lter hose on the suction side of your ltration unit to the 8905 hose adapter on the bottom of the skimmer housing. Secure with a hose clamp.

(If air is getting into your pump system white you are ltering or vacuuming your pool. Check the hose connections between the skimmer housing and

pump inlet tor an airtight t and that you have a good seat with the hose adapters by using the Teon tape on all pipe threads, or check water level to

make sure it's at least midway up on the face plate)

i. Using the skimmer face plate as a guide, use a razor blade or sharp knife to trim only the liner, being careful not to cut the gasket.

5. Return Fitting Installation Procedure:

a. Gently press the vinyl liner at the circular wall-tting opening to locate the exact position. Make a circular cutout in the vinyl approximately 3/4" smaller

than the opening in the wall.

b. Disassemble the 8949 return tting.

c. Screw the remaining 8905 hose adapter into the return tting opposite of the ange end. Use theTeon tape for a sealant. Use caution not to

over tighten as it may crack the tting. Never use any type to glue or sealant on the pipe threads.

d. Place one of the rubber gaskets, from the 3 pc gasket set, on the tting and insert through the vinyl liner and wall panel.The eyeball side should be inside

the pool. Next, place the cork gaskets followed by the rubber gasket over the rear of the tting and screw the locknut hub up tightly.

e. Screw the adjustable directional ball tting into the ange side of the tting. Direct the ow of water away from the skimmer opening.

f. Connect the return hose to the pressure side of your ltration system. Secure with a hose clamp.

OPERATING INSTRUCTIONS:

1. Make sure you keep the water level in the pool midway up the face plate. If the water level falls below the recommended level, water may cavitate in the housing

and cause the pool pump to lose its prime.

2.To adjust the inlet ow direction loosen the knurled outer ring of the "eyeball" portion and move the ball to the desired position.

3.To clean the 8928-skimmer basket, remove the 8927 top cover; and remove the basket. It is recommended that the pool pump be shut o.

4.To vacuum the pool follow these directions:

a. Remove the top cover or fold the 8926-weir ap forward and squeeze pins toward the center and remove. It is not necessary to remove the 8928 basket.

b. Fill your vacuum hose with water by temporarily inserting the hose cu into the return tting while the pool pump is on. Make sure all the air is removed from the hose.

c.Take the 8929Vac adapter, which consists of the plate and elbow, and attach to the hose through the opening of the wall and place down inside the housing.

Try to keep the hose cu submerged during this process so no air gets back into the hose to cause the pump to cavitate and lose its prime.

WINTERIZING PROCEDURE:

Drain pool level approximately 2" to 4" below skimmer opening. Remove the"eyeball" tting in return and securely plug wall tting with 1-1/2" plugs from your dealer.
