ABOVE GROUND POOL SAFETY
warning
FAILURE TO HEED THESE WARNINGS CAN RESULTIN PERMANENT INJURY,
PARALYSIS FROM A BROKEN NECK, ELECTROCUTION OR DROWNING.
THIS POOL IS NOT DESIGNED FOR DIVING OR JUMPING!
DANGEROUS INJURY CAN RESULT. SHALLOW WATER!
Your pool contains a large quantity of water, and is deep enough to present inherent dangers to life and health unless the
following safety rules are strictly observed. First-time users run the highest risk of injury. Make sure everyone understands and
encourage all users especially children to learn how to swim. Learn Basic Life Support (Cardiopulmonary Resuscitation-CPR)
and refresh this knowledge regularly. Instruct all pool users, including children, what to do in case of an emergency. Keep a
working phone and a list of emergency phone numbers near the pool. This can make a life-saving di󰀨erence in the event of an
emergency. To ensure your pool is used safely you MUST observe the following safety precautions:
1. NO JUMPING OR DIVING
The top rail of your pool is not a walkway and must not be used for jumping or diving. Do not
permit jumping or diving into the pool from a deck or the top rail of the pool. Diving or jumping
into the pool can result in serious injury.
2. NEVER USE THE POOL ALONE
Never permit the pool to be used unless it is attended by at least one person other than the
bather. Someone should always be available to lend assistance in an emergency. Designate a
competent adult to supervise the pool each time it is being used. Vigilant supervision of weak
swimmers and non-swimmers by a competent adult is required at all times, remembering that
children under ve are at the highest risk of drowning.
3. NEVER LEAVE CHILDREN UNATTENDED
Never leave a child alone and unsupervised in or near the pool—not even for a second. There
is no substitute for constant adult supervision.
4. NO ROUGH PLAY
Do not permit “roughhousing” in and around your pool. Surfaces can become slippery and
hazardous when wet.
5. LIGHT THE POOL AT NIGHT
If the pool is used after dusk, adequate lighting must be provided. Illumination in the pool area
must be sufcient to clearly judge pool depth and all features in and around the pool. For light-
ing recommendations, consult your local licensed electrical contractor
6. RESTRICT ACCESS TO THE POOL
Do not leave chairs or other furniture beside the pool that could be used by a child to climb
up into the pool. Ladders must be removed whenever the pool is unattended. A fence with a
lockable gate around the pool or yard is strongly recommended and may be required by law
in some jurisdictions. Secure doors and windows, where applicable to prevent unauthorized
access to the swimming pool. Remove all toys from the swimming pool and surrounding area
when not in use to avoid attracting children to the pool. Barriers, pool covers, pool alarms
or similar safety devices are helpful aids, but they are not substitutes for continuous adult
supervision.
7. NO ALCOHOL OR DRUGS
Never drink alcoholic beverages, use any intoxicants or medication which could hinder your
judgment and reexes.
8. KEEP YOUR POOL CLEAN AND SANITARY
Your lter system will remove suspended particles from the water and the surface skimmer
will remove insects, leaves and other debris from the water surface. Use the correct pool
chemicals as directed to destroy harmful bacteria and prevent formation of algae. Remember,
unsanitary water is a serious health hazard.
The safety stickers must be installed as per following instructions. Failure to properly install warning labels will void warranty. Failure
to mount these safety labels may subject you to substantial liability in case of injury. These warnings are not to be removed under
any circumstances! If they become discolored or fall o󰀨 please request replacements which will be sent at no charge.
FOLLOW ALL SAFETY INSTRUCTIONS
Read and follow all safety instructions packaged with pool, ladder,
deck or any other accessory. Additional pool safety publications can be
obtained by contacting: The Association of Pool & Spa Professionals
(www.apsp.org)
important notice read before installation!
9. KEEP OFF TOP LEDGES
Do not walk on top ledges. They can be slippery and they are not a walkway.
10. POOL COVER SAFETY
The cover must have a tamperproof locking retainer cable that positions the cover around the
pool wall and keeps it securely in place. Never allow anyone, especially small children on the
cover. Asphyxiation or drowning could result. Be sure to remove pool cover completely from
the water surface before entering the pool. When purchasing any pool cover, please consult a
swimming pool professional.
11. ELECTRICAL HAZARD
Never touch or attempt to service electrical equipment, including the lter when your body and/
or the ground is wet. Electrocution or permanent injury due to high voltage (120V AC) could
result. The pool should be bonded in accordance with Section 680-26 of the National Electical
Code. For further assistance contact your dealer or a local licensed electrician. Do not use pool
during electrical or rain storms.
12. SAFETY EQUIPMENT
Keep a safety rope 1/4" by 50" with a otation buoy with an outside diamter of 15". Have
accessible in a prominent area by your pool. Keep a pole not less that 16 feet (4,88m) long
with a blunt or hook end available at poolside in case of emergencies. Weak swimmers and
non-swimmers should wear personal protection equipment when using the pool.
13. POOL CHEMICALS
Store pool chemicals out of the reach of children. Do not place chlorine, chlorine tablets or
sticks directly into skimmer, or winterize your pool with liquid chlorine. Damage to the skimmer,
pool liner and lter will result. Failure to obey this instruction will void all component warranties.
Always follow chemical manufacturer’s instructions when storing, handling and dispensing pool
chemicals.
14. CHECK FOR DAMAGE
Periodically check your pool and ladder components for damage and wear. Be sure all screws
are in place. Replace all damaged or worn components and tighten all screws before you use
the pool, deck or ladders. At rst sign, remove rust and touch up immediately.
15. POOL PARTS
Never modify the pool or accessories, or remove or drill holes in the pool, deck or ladder com-
ponents unless instructed. Your pool wall is made of thin metal, there is an inherent cut hazard
with metal so use gloves during installation. Always use Original Equipment Manufactured parts
for your replacement parts.

A. DETERMINE THE LOCATION OF YOUR POOL
1. The Terrain
Pay special attention to choosing the right location for
your pool:
• Choose a large area, as flat and level as possible and
well drained. (Image 1)
• Choose a spot on dry, firm earth (stabilizer or
other)—do not install the pool on asphalt, tar or oil
based surfaces, gravel, peat moss, wood or chemically
treated soil.
• Check with your pool dealer to see if Nut Grass grows
in your area. This type of grass may grow up through
your pool liner. Your dealer will be able to advise how
best to treat the site.
• Sloped areas will need to be made level by digging
away high spots, not by filling low spots—be prepared
to hire earth-moving equipment if necessary.
(Images 2a & 2b)
• Ensure the earth is well compacted and a wall is
placed to prevent the earth from seeping out.
(Image 2a)
• If you need to install partly in the ground, you
must contact your dealer to see if this is an option
for you and that you meet law requirements in your
jurisdiction. (Image 2c)

Important Note:
Ground preparation is one of the most important steps in
the installation process. A proper foundation will ensure
the rest of the pool assembly goes smoothly and that no
problems will occur when the pool is filled with water.

A. CONT. DETERMINE THE LOCATION OF YOUR POOL
2. Things to Avoid
Do not locate your pool near or on any of the following
(Images 3a to 3c):
• Overhanging tree branches.
• Overhead wires and clotheslines.
• Buried pipes and wires. Contact your gas, electric
and telephone utilities to find buried pipes and wires
before you dig.
• Areas with poor drainage.
• Grass, stones and roots. Grass will rot underneath the
pool liner, and stones and roots will damage the pool
liner.
• Areas recently treated with oil-based weed killers,
chemicals or fertilizers.
3. Plan Ahead
• Will you be adding an adjacent deck later?
Be sure to leave room.
• Will you be using pool accessories or other
appliances that need electricity or gas? Locate your
pool near these services or plan to have them installed
later by a licensed contractor.
Important Note:
When locating the centre of the pool, be sure to take
into consideration any structures (deck, patio, house)
or relevant items (change rooms, gazebo, etc.) that the
pool may need to line up with and ensure that the pool
is in the most visual pleasing location for your property.

e. Be prepared to hire earth moving equipment if you
need to level a large area. Remember, your pool
must be level across the diameter of the pool.
(Image 7)
f. Small dips and hollows may be filled in, but the soil
must be hard-packed and well compacted with a
tamping tool.
g. Take material such as rock dust or fine mortar
that can conform a solid, permanent base and
deposit this material around the rim of the basin.
The material used should be spread around the
perimeter of the pool to a width of 24” (60cm) and
a thickness of 2” (5cm). (Image 8)
Note: Bottom rails will be placed in the center of the
perimeter of the pool see the dashed line. (Image 8)
h. Recheck the outer perimeter of the circle, where
the pool wall will be. Compact the ground and
make sure there are no high or low spots. The
bottom edge of the pool wall must rest flat on the
ground and have no gaps under it. (Image 9)

i. Go over the entire perimeter of the pool to ensure
that at every 3“ the surface is completely level.
j. Lay out the bottom rails and bottom plates around
the circle.
k. Check the roundness of your circle, by measuring
the diameter across in several locations. Since the
bottom rails do not automatically form a true circle,
DO NOT SKIP THIS STEP! Otherwise you might end
up with a slightly oval shape, which can cause
problems later on. (Image 10)
l. Verify the height of each bottom plate with an
optical level. They have to be at the same height.
Adjust height if necessary.

4. Patio Stones (Recommended)
a. Concrete patio stones may be placed at the base
of each upright of your pool.
b. Each bottom plate will show the location for a patio
stone. Make a mark in the ground at each base
plate. (Image 12)
c. Remove the bottom rails and bottom plates and lay
out the patio stones around the circle where the
bottom plates were. (Image 13)
d. The patio stones must be sunk into the ground so
the tops are flush with the soil around them. Use
the carpenter’s level to make sure the patio stones
are perfectly level and flush with the ground. Use
either the carpenter’s level and a 2-by-4 (5cm x
10cm) wood plank, or the optical level between
patio stones to make sure the stones are level with
each other. (Image 14)
e. Do not install blocks or rails on loose sifted soil or
sand. There must be no space between the ground
and the bottom of the rails. All patio blocks must
be flush with the ground, solid and level with each
other in all directions.
NOTE: Installing patio blocks is recommended.
Patio blocks may shift due to temperature changes.

1. Lay out bottom plates
a. Place the bottom plates equally spaced around the
perimeter of your foundation. If you are using the
optional patio stones, depending on your model
place one bottom plate on each stone. (Image 1)
2. Assemble bottom plates and bottom rails
a. Insert the end of each bottom rail into a bottom
plate. Leave a gap between the ends of the bottom
rails. (Images 2-3 )
b. Measure the diameter of your pool all around the
circle and make sure it is correct.
Note: this measurement should be taken from cen-
tre to centre of the bottom plate. When the circum-
ference is perfectly round, hammer nails into the
ground to keep the bottom rails into place.
These nails are to be removed only at the last step-
when filling up the pool.

1. Preparing for the wall installation
a. Bring the following items into the middle of the pool
foundation before you start uncoiling the pool wall:
plywood, some extra sand or fine dirt to make the
cove and a ladder to climb out after the wall is as-
sembled.
b. Make sure the skimmer and water return holes are
located where you need them to be. The skimmer
and water return holes are positioned towards the
end of the wall, (the section before where the wall
started).
2. Set the pool wall in place
a. Unpackage the coiled pool wall and stand it on the
plywood at the place close to where you need to
install the skimmer. (Image 1)
(Remember the skimmer and water return holes
will be placed at the section just before where you
started the wall installation).
b. Start uncoiling the wall, guiding the bottom edge
into the curved bottom rail. The starting end of the
wall must be positioned in the centre of a bottom
plate, and the skimmer and return holes should be
positioned where the pump and filter will be.
(Image 2)
c. Set lengths of stabilizer onto the top edge of the
wall as you uncoil it. (Image 2)
