POOL PREPARATION
The pool must be properly erected per Doughboy's Pool
Assembly & Installation Instructions. There should be
approximately 2' of water up the metal wall so that the
liner is under weight and stretched to proper position
prior to installing skim filter. NOTE: The liner cannot be
shifted after the skim filter entry holes have been cut.
SKIM FILTER INSTALLATION
1. Remove all components from carton. Remove lid
from filter assembly by sliding forward and lifting.
Remove basket, hardware package and filter
element from filter.
2. Attach weir assembly (30) to skim filter (10) using
three screws (20). Push the weir inside the filter so
that the foam side is down.
3. If you are installing onto a Doughboy Classic 8 1/2”
pool, you will need to use a Doughboy Skimmer
Extension (model # 0-2351-001) with this skimmer.
The instructions provided with the extension will
replace steps 4 thru 6 of this owner’s guide. Refer
to those instructions at this time to proceed with
installation. When you have finished that portion of
the assembly, return to step 7 in this owner’s guide
to complete skimmer and return fitting installation.
4. Reach over the top rail and carefully press the
liner against the skim filter cutout in the wall.Punch
out the two top corner holes using a nail.
5. Place one skimmer gasket (27) on faceplate
(26). Insert two large self-threading screws (25) into
top corner holes. With these screws protruding
through the top corner holes of them gasket (27),
carefully push the screws through the holes which
have been pierced in the liner. Place the second
gasket (27) on the exposed screw threads outside
the pool wall. From the outside of the pool, align the
skim filter with these screws. Tighten the two
screws just until they start to grab the skim filter
body.
6. Position both inside and outside gaskets so that
flanges of the filter and faceplate are in contact with
the gasket. Using a nail and the faceplate as a

Doughboy's Skim-Line Vacuum Skim Filter makes
pool maintenance easier, faster and very convenient.
The filter skims floating leaves, insects and dust
from the pool surface, and collects the debris in a
skimmer basket. The collected water and debris are
pulled down through a high-action filter element.
The tiny particles of debris are trapped in the ele-
ment and the water is "polished" to sparkling clarity.
Doughboy's powerful Pool Power Pak®then returns
the polished water back into the pool. Just follow
the easy directions in this guide and your pool will
soon be sparkling clean! The numbers in parenthe-
ses (00) refer to key numbers in the illustration on
page 7.

HOSE CONNECTION
1. Place the Power Pak®approximately 5 feet from the
pool wall so that it may not be used as a step by
children. Position Power Pak®on a 14" x 14" patio
block. Do not place the Power Pak ®directly on the
ground as the vents in the pump housing may be
obstructed causing the motor to overheat. NOTE:
Refer to your Power Pak instructions for assem-
bling hose adaptor to pump suction. See Fig. 1.
2. Slide hose clamps (11) over ends of hoses (12).
Slip one end on barbed port at bottom of skim filter
(10) . Slip opposite end on pump suction. Tighten
clamps.
3. Slip one end of the other hose on barbed port of
pump discharge (on top). Slip opposite end on
return fitting body (19). Tighten clamps.
4. You may want to dig two 3" deep trenches to lay
the hoses into. The trenches should start at least
12" from the pool wall. Cover the trenches with a
firm board. NOTE: Do not bury the hoses.
PRIOR TO OPERATION
Pool water must be between markers on skim filter
faceplate. Reinstall the element into the filter by
gripping the handle on top and lowering it into the filter.
The hole in the bottom of the element slips over a tube
extending up from the bottom. It is designed to self-
position itself on the tube. Push down on the element
with a rotating motion until fully seated on the bottom.
Air bubbles will exit from the top of the element for
several seconds. After air is fully expelled, recheck to
be sure element is fully seated. Position basket (2) into
place above the element, resting basket flange on rim
by pressing basket downward to engage element
handle. Install lid (1). Plug the cord of your Pool Power
Pak into grounded electrical supply as described in
Pool Power Pak instructions.
The filter is designed to work with the Pool Power
Pak provided. Use of a pump with a greater flow
may cause damage to the filter tank.
OPERATION
When the skim filter is in operation, water flows into the
skimmer opening. Floating surface debris is pulled in
over the weir and is caught in the basket. Finer sus-
pended particles pass through the basket and are
trapped on the element surfaces. Clean filtered water
inside the element then flows through the pump and
return fitting back into the pool.
Be sure hoses are connected and element is installed
in filter. Start your Pool Power Pak. Water flow from
the return fitting should begin within a few seconds. If
not, stop pump and blow out air from the hoses by
forcing water from a garden hose through the return
fitting eyeball (14) until air bubbles stop appearing
inside the filter tank.
Start pump and repeat garden hose procedure if
necessary until water is flowing steadily from the return
fitting. You may notice fine air bubbles coming out of
guide, pierce the 13 additional holes in the liner.
Insert and lightly tighten the remaining 13 screws
(25) through the faceplate, gasket, liner, pool wall,
gasket and into corresponding holes on the skim
filter. Firmly tighten all screws evenly, alternating left
and right, top and bottom.
7. Using a razor knife, trim the liner. Being careful not
to cut the gaskets, use the faceplate (26) as a guide
to trim the liner in the large skimmer opening, and
vacuum adaptor opening.
8. Attach vacuum port cover (23) and retainer (22) to
faceplate using screw (20).
RETURN FITTING INSTALLATION
1. Locate a board large enough to cover return fitting
cutout. From inside of pool, use the board to hold
liner against cutout in pool wall. Keep hands away
from hole to avoid injury. From outside of pool, use
the cutout as a guide and cut away liner with a razor
knife.
2. Slip a gasket (18) over the threads of the return fitting
adaptor (17) and push threaded end through the wall
from inside pool. Place the second gasket over the
threads now exposed outside the pool.
3. Hold the return fitting body (19) so the hose fitting
end points straight up while turning the adaptor from
inside the pool. When the adaptor just begins to
crush gaskets, hold adaptor from turning while
rotating the body clockwise to its straight down
position.
4. If the assembly does not feel snug, rotate the return
fitting body back to the up position. Rotate the
adaptor inside pool an additional 1/4 turn, then rotate
the body to the down position again. Repeat this
procedure as required.
5. Install eyeball insert (15) into eyeball (14). Hold the
eyeball inside the adaptor (17) with insert toward
inside. Thread on return fitting cover (13) to secure
eyeball position so it directs flow away from skimmer
opening. Do not overtighten.

FACEPLATE

the return fitting for a while until all air has been pulled
from the element in the normal filtering cycle. Continu-
ous air flowing out of the return fitting means that you
have loose hose connection between the pump and
filter, or that the hose adaptor on the pump suction is
loose. Tighten if necessary. Check for any leaks where
skim filter is attached to wall and tighten screws (25) if
necessary.
FIRST-TIME FILTRATION
Your skim filter will work extra hard to clean new,
unfiltered water during the first days of operation. If you
can easily see the bottom of your pool through clear
water, you may not need to clean the filter element for
several days to a week. However, slightly cloudy pool
water may require daily cleaning for the first few days.
Discolored water that appears greenish, grey-blue, or
reddish may contain a heavy load of algae spores,
suspended minerals, or super-fine particles. This is a
severe condition that rapidly "blinds off" the fibers of the
element filtering cloth, cutting off water flow through the
element. When the element blinds off, little or no water
is returned to the pool through the return fitting opening.
This could occur repeatedly, requiring that you clean the
element many times in one day, until all pool water is
thoroughly cleaned by the filter. After the filter has
successfully cleaned the newly filled pool, you can
expect many days to a few weeks of excellent filtering
between each element cleaning. Cleaning cycles will
depend on the size of your pool, amount of water being
filtered, airborne debris, and degree
of pool use.
ROUTINE CARE & MAINTENANCE
KEEP YOUR POOL SPARKLING
You can take steps to reduce the amount of mainte-
nance needed to keep your pool sparkling.
1. Provide a clean walkway leading to your pool
entrance.
2. Rinse off patio and area around pool regularly.
3. Swimmers should rinse off (especially their feet)
before entering pool.
4. Maintain the proper chemical balance in your pool.
Hot days will cause chemicals to dissipate rapidly.
5. Remove floating leaves and debris with a leaf
skimmer.
6. Empty skimmer basket frequently.
7. Vacuum pool bottom to remove settled debris.
8. A pool cover will help keep your pool clean during
high winds or rainfall.
POOL CARE
Refer to your "SAFETY FIRST Pool Use Handbook" for
general pool care and chemical treatment information.
This booklet is included in your pool package. 4
CHLORINE INSTRUCTIONS
ALWAYS READ AND FOLLOW CHEMICAL
MANUFACTURER'S SAFETY PRECAUTIONS
FOR HANDLING CHLORINE
WARNING! DO NOT PLACE CHLORINE TABLETS IN
THE SKIMMER BASKET! Putting chlorine tablets
directly into the skimmer basket will destroy the filter
element. Chlorine in high amounts eats away the
material and will in time destroy the filter element. We
recommend against adding any kind of chemicals
directly into the skimmer!
Please read the following instructions carefully. Chlorine
is a strong chemical. Improper use could result in
serious, permanent damage to the pool liner. This
damage could include "white spots", wrinkles or
breakage (brittle vinyl). Such damage is not covered
under warranty.
IMPORTANT: Pump and filter should always be "ON"
when adding any chemicals to pool water.
WITH DISPENSER
Dry Chlorine (tablets, sticks, granules, or powder). Use
one of the following types of chlorine dispensers:
• Floating Dispenser: Use only when pump and
filter are running. Dispenser must circulate in pool
for proper distribution of chlorine.
• Automatic feeder (in-line or off-line).
• Chlorine generator - Approved for use.
Releases chlorine from salt.
Ask your Doughboy dealer to recommend the best type
of dispenser for your pool and area conditions. Follow
manufacturer's instructions for correct use.
WITHOUT DISPENSER
Dry Chlorine: Use granules or powder only. NEVER
pour dry chlorine directly into the pool water. Mix with
pool water in a clean plastic container following chlorine
manufacturer's safety instructions. When all chlorine
has dissolved, pour solution into pool water at the return
fitting. Water returning to the pool will properly distribute
chlorine.
Liquid Chlorine: Liquid chlorine concentrate may be
poured directly into pool water. Carefully add liquid
chlorine to water at the return fitting. Water returning to
the pool will distribute the chlorine. Follow chemical
manufacturer's instructions for use of liquid chlorine.
EMPTY SKIMMER BASKET
Stop pump. Remove lid (1). CAUTION: Before lifting
out basket and emptying, check inside opening above
basket for "STILL ALIVE" insects such as hornets, bees,
etc., that may sting you. Then slowly lift out basket and
empty. Replace skimmer basket and lid. Start pump.

9. HARD WATER: Hard water will eventually coat the
element with calcium deposits that cut off good
filtering action. To correct, mix a solution of 1 part
muriatic acid to 4 parts water. Soak the element
fully submerged about 15 minutes. Rinse thor-
oughly with clean water. Replace element, basket
and lid. Resume normal filtering operation. CAU-
TION: Chlorine and acids kill lawns and plant life.
Clean element in suitable area.
VACUUMING
Prior to vacuuming, empty the basket and clean the
element. For high wind areas and exceptionally dirty
pools, filter must be checked and flushed through drain
valve (7) frequently. Excessive amounts of dirt, sand or
debris will cause element to become wedged inside
filter.
1. Stop pump. Assemble vacuum head, handle and
hose. (A good smooth bore 1 1/2" hose will give
you the best vacuuming results). Attach free end of
hose to the large end of vacuum adaptor (21).
2. Start pump. Hold the free end of the hose against
the return fitting discharge. This will force air from
the hose. When the bubbles cease to rise from the
vacuum head, all the air is removed. (Figs. 5 and
6). Stop pump.
3. Bend the vacuum port cover (23) to the down
position. Insert the tapered end vacuum adaptor
with hose attached into exposed opening using a
twisting motion (Fig. 7).
5
CLEANING FILTER ELEMENT
As the element becomes saturated with dirt and debris,
the return flow back into the pool will tend to diminish. At
this time the element must be cleaned. Pay CAREFUL
attention to flushing the tank prior to removing the
element to prevent debris from clogging the pump
impeller. (See instructions below.)
1. Stop pump. Remove lid (1) and basket (2) from filter.
2. Lay out a 1 1/2" waste hose from the filter drain valve
(7) to a convenient disposal point. Remove cap (9)
on drain valve and attach hose.
3. Flushing the tank: Turn handle on drain valve to
the open position (rotate 180ountil handle stops).
Dirt and debris in the bottom of the tank are now
being flushed to waste.
4. While the tank is being flushed, lift the element
approximately 1" and rotate back and forth to dis-
lodge heavily collected debris. This allows the debris
to be flushed out of the tank. When the flush water is
clear, slowly lift the element out of tank. Continue
flushing additional debris from the element as you
remove it. When flush water again clears, shut valve
"OFF". CAUTION: Never lay element on its side on
a rough textured surface such as concrete, asphalt,
gravel, etc. Damage to the pleated filtering material
may occur. THIS WILL SERIOUSLY REDUCE
FILTERING PERFORMANCE.
5. Remove waste hose and replace valve drain cap (9)
making sure gasket (8) is in place and properly
seated. (DO NOT OVERTIGHTEN.)
6. Attach the blaster nozzle (4) to a garden hose. Use
the handle on top to hold the element in an upright
position with one hand. Hold the blaster nozzle away
from the element about 18". Starting at the top of the
element, spray between each pleat, working down-
ward.
NOTE: If the element becomes impregnated with
algae, pour a mild chlorine solution (1 part chlorine to
4 parts water) over all pleated surfaces and let soak
for 10 minutes then hose off thoroughly.
7. Mix a solution of warm water and detergent (1 cup
per 5 gallons of water). Add one cup chlorine
(sodium hypochlorite or household bleach). Totally
submerge the element and soak for 15-30 minutes.
Agitate the element vigorously to dislodge trapped
particles.
8. Rinse element thoroughly before reinstalling in the
filter. If the element is not rinsed clean, soapy
bubbles will appear on the pool surface near the
return fitting. When element is clean, replace it, the
basket and lid in the filter. Resume normal filter
operation.

4. The lid (1) performs two functions. In normal posi-
tion, it covers the top of the filter. During vacuum-
ing, this same lid becomes the sealing plate for the
vacuuming. Be sure pump is "OFF". Remove the
lid and lower it inside (handle grip up) to rest on the
rectangular hole above basket. Make sure air is not
trapped under the lid. Trapped air will cause the lid
to rise.
CAUTION: Never attempt to install the lid in the
vacuuming position while your Pool Power Pak is
running. The lid may suddenly be drawn down into
position due to the pump's high suction action. You
may injure your hands or fingers.
5. With the lid in place, start pump and operate
vacuum over pool floor.
6. When finished vacuuming, stop pump . Remove
vacuum hose with vacuum adaptor attached from
the pool. Clean skimmer basket and element.
Move lid to the original position on top of the filter.
Start pump to resume normal filtering operation.

WINTERIZING (FREEZING CLIMATES)
We strongly recommend, for the protection of your filter,
liner and pool wall, that you purchase and install the
DOUGHBOY Winterizing Kit (0-2099-001). The proper
installation of this kit will allow the removal and storage
of your filter and should eliminate any possibility of
damage due to winter peril. CAUTION: Removing the
Skim-Filter without installing a Winterizing Kit is very
dangerous to the pool wall, liner and pool installation,
and voids any warranty. Filter damage caused by
freezing temperatures is not covered by product
warranty.
1. Drain pool to 6 inches below the eyeball return
fitting.
2. Remove, clean and store in warm area: basket,
element, hoses and Pool Power Pak.
3. Remove filter from pool, clean and store. Install the
DOUGHBOY Winterizing Kit per Kit instructions.
4. Remove the return fitting eyeball by unscrewing the
cover. Replace the eyeball with the shut-off disc
(16) and reinstall the cover. NOTE: This shut-off
disc can be useful for plugging off the return fitting
should maintenance be required on the filter or
Power Pak.
5. For spring start-up, follow instructions under
INSTALLATION in this guide.

C. ALWAYS BE SURE THE GROUND UNDER YOUR
FEET, AND YOUR BODY, IS DRY before you
touch filter or pump electrical equipment. Failure to
heed this warning may cause personal injury due to
severe electrical shock.
D. ALWAYS have a qualified electrician service your
system if electrical problems occur.
E. ALWAYS have a qualified electrician install a
Ground Fault Circuit Interrupter (GFCI) breaker
at the electrical service or supply panel. Follow
GFCI manufacturer's operating instructions for
testing. Failure to do so may cause personal injury
due to severe electrical shock.
CAUTION: To reduce the risk of electrical shock,
connect only to grounding type receptacles. A
Ground Fault Circuit Interrupter (GFCI) must be
provided in accordance with Article 680 of the
National Electrical Code (NEC) and local codes or
ordinances.
CAUTION: To reduce the risk of electrical shock,
use only Original Equipment Manufactured (OEM)
replacement parts when servicing.
IMPORTANT FILTER/PUMP SAFETY
1. DO NOT install pump on a deck. It could fall into
the water, causing severe electrical shock.
Do not install on any surface at, above, or slightly
below the top rail of the pool.
2. DO NOT allow children or adults to climb, sit, or
stand on the filter or pump units. They could easily
fall. Position pump approximately 5 feet from pool
wall so it may not be used as a step by children
3. CAUTION pool users to stay away from the skim-
mer opening. Strong suction can pull hair into the
opening, trapping the person and causing injury.
4. FAILURE to keep faceplate mounting screws
and return fitting tight may cause leakage between
skimmer and pool wall. Continued leakage may
cause wall damage which eventually may result in
pool wall failure.
SERVICING SAFETY TIPS
A. ALWAYS TURN "OFF" the main power switch
and the Ground Fault Circuit Interrupter (GFCI)
breaker switch so power is completely off before
servicing your unit.
B. ALWAYS STOP PUMP before you service, tighten,
or adjust the filter assembly.
