Dear Pool Cover Owner:
Congratulations on the purchase of your new Infinity 4000™Automatic Safety
Swimming Pool Cover.
We, at Pool Cover Specialists® are committed to helping you create a safer
swimming environment and bringing the peace of mind that comes from knowing your pool
is secure. The products you have purchased are the compilation of over 33 years of design
and experience dedicated to making our products the longest-lasting and safest automatic
Swimming Pool Covers available.
In spite of growing awareness in pool safety, drowning still ranks among the leading
causes of death for young children. Consequently, we wish to stress the following precautions:
 Layers of protection are strongly recommended; like fences, self-locking gates,
alarms and cameras, etc. Your new safety pool cover is an excellent layer of
protection.
 There is no substitute for constant adult supervision. Most drownings happen
during a five-minute-or-less lapse in supervision.
 Do not consider young children “water safe” just because they have had swimming
lessons.
 Instruct babysitters and others about potential backyard hazards.
 Install a telephone poolside with emergency numbers and location address posted
in case of an accident.
 Always completely open your pool cover before bathers enter the water to prevent
possible entrapment.
These are just a few precautions and suggestions. Please take a few moments to read the
Owner’s Manual as it contains important safety, operational and care information about
your pool cover.
From all of us at Pool Cover Specialists®, thank you and enjoy your pool and pool cover.
Be Safe, Be Wise, Swim Safely!

ASTM F1346-91(2010) Safety Standard
The American Society for Testing Materials established recommendations
for Powered and Manual Safety Pool Covers in 1991.
These recommendations were reviewed and updated in 2010 and is now
referred to as the ASTM F1346-91(10) standard. All Pool Cover Specialists®pool and
spa covers have been tested in accordance with this standard and meet or exceed all
requirements when installed and maintained according to Pool Cover Specialists®
instructions.
Main provisions of the standard are:
•The pool cover system must be labeled with multiple WARNING labels.
(Replacement labels are available for free)
•The pool cover system must support the weight of two adults and a child (485
lbs.) in case of an emergency.
•The pool cover must be operated from a fixed position where the entire surface
of the pool can be viewed during operation.
•The switch must be mounted at least 5 feet above the deck or a locking switch
mounted in an inaccessible location in accordance with local electrical code.
•An object 3.70 (approximately 3-5/8") in diameter shall not be able to slide under
the pool cover.
•An automatic water discharging system (self-starting pool cover pump) must be
used whenever the pool cover is closed. The pump must be placed on the pool
cover at all times so rain or other water sources can be removed within 30
minutes of water source discontinuing.
Please check your installation and confirm that these standards have been met.
If any of these standards have not been met, i.e. the pool cover pump is not present
and on the pool cover, then by definition your pool cover is not a safety pool cover.

POOLSAFETYTIPS
Thank you for purchasing a Pool Cover Specialists ® Automatic Safety Swimming Pool Cover.
We make every effort to provide you with the safest products available,
and also stress the following preventative safety tips:
A swimming pool can provide your family and friends with an oasis of
tranquility, hours of entertainment and healthy recreation. To maintain that
tranquility be aware that as a pool owner you must ensure the safety of your pool
area. There is a risk of a child drowning whenever children are around any body
of water.
There is no substitute for constant adult supervision when children are
around a pool. Most drownings occur with a lapse in supervision of five minutes
or less. By providing layers of protection between children and the pool, you can
avoid a tragic accident when you are not there.
Supervision
 Never swim alone.
 Practice “Active Supervision” when young children are in and around the pool;
keep them within arm’s reach and maintain eye contact. Always supervise
children of all ages.
 Don’t consider a child “water-safe” just because they have had swimming
lessons.
 Never leave a child alone in or around the water.
 Keep toys away from the pool when not in use; they can lure a child into the pool
and pool area.
 Use inflatable toys only under adult supervision; they may deflate or your child
may slip off into the pool.
 Post and enforce pool rules such as No Running, No Pushing, No Dunking and
Never Swim Alone.
 Instruct babysitters, caregivers and neighbors of pool area hazards to young
children in and around swimming pools and the need for constant supervision.
 Alert your pool maintenance personnel, utility personnel, and your neighbors to
keep pool covers, gates and doors to pool closed and locked at all times.
 Never use a pool with its pool cover partially in place; bathers may become
trapped under the pool cover.
 Consider having responsible persons take turns and be the “Lifeguard on Duty”
during gatherings around the pool or pool party. During their turn they place 100
percent attention on watching the pool.
 Beware of free-floating pool covers; a child can slip beneath unnoticed.

Layers of protection
 Don’t rely on a single layer of protection; multiple safety precautions provide the
strongest safeguards.
 Enclose the pool with an isolation barrier such as an ASTM Certified Automatic
Safety Swimming Pool Cover and full perimeter fence with self-closing and
locking gates.
 Place table and chairs well away from the pool fence to prevent children from
climbing into the pool area.
 Keep all doors and windows secure leading from the house to the pool area.
Install self-closing mechanisms on doors.
 Additional layers may also include pool water alarms, and alarms on the door to
the pool.
 Check to ensure that spa and pool covers pass minimum safety requirements set
by the American Society of Testing Materials.
 Be aware that a child can drown in as little as two inches of water.
 Remove ladders and steps from above-ground pools. No objects should be in the
pool area for a child to climb onto and then into the water.
 Inspect safety and pool equipment regularly. Preventive devices are only
effective if they are in working order.
Preparedness
 Learn CPR (Cardiopulmonary Resuscitation) and first aid. Have all caretakers and
responsible individuals learn CPR and first aid.
 Have a first aid kit ready and available in the pool area.
 Post emergency numbers and the pool address in the pool area.
 Install a telephone, or have one available at poolside.
 Make sure you have rescue devices accessible at the poolside; like a shepherds
hook and life ring with the rope attached.
 Know where the electrical shutoff to your pool equipment and pool cover are
and how to turn off the power in case of emergency.

CPR IN THREE SIMPLE STEPS
(Please try to attend a CPR training course)
CONTINUE WITH 30 PUMPS AND 2 BREATHS UNTIL HELP ARRIVES
NOTE: This ratio is the same for one-person and two-person CPR. In two-person CPR the person pumping
the chest stops while the other gives mouth-to-mouth breathing.
Sources: United States Consumer Product Safety Commissions; National Spa and Pool Institute’s
Operation Water Watch; and the American Academy of Pediatrics. depts.washington.edu/learncpr.html
1. CALL
Check the victim for unresponsiveness. If
the person is not responsive and
breathing or not breathing normally. Call
911 and return to the victim. In most
locations the emergency dispatcher can
assist you with CPR instructions.
2. PUMP
If the victim is still not breathing
normally, coughing or moving, begin
chest compressions. Push down in the
center of the chest 2 inches 30 times.
Pump hard and fast at the rate of at least
100/minute, faster than once per second.
3. BLOW
Tilt the head back and lift the chin. Pinch
nose and cover the mouth with yours
and blow until you see the chest rise.
Give 2 breaths. Each breath should take
1 second.

Pool Cover Operation
Before operating the pool cover
 Inspect and make sure no bathers or pets are in or around the pool.
 Inspect and remove any obstructions (pool toys, towels, ladders, patio
furniture etc.).
 Clear and remove any water or debris from on top of the pool cover (leaves,
twigs, etc.). Use a pool brush and pool cover pump per the manufacturer’s
instructions.
 Un-plug and then remove the pool cover pump from the pool cover and the
recreational area before operating the pool cover or swimming in the pool.
Operating the pool cover
Based on your choice of accessories your pool cover will be controlled by either a Key
Switch or a Touch Pad mounted in full view of the pool.
•Key Switch:
oInsert the key, turn and hold the key in the open or close position until the
pool cover has completed the operation, then release the key. The
operation can be stopped at any time by simply releasing the key. Visually
monitor the operation of the pool cover for safety or problems as you hold

Water Removal and Pool Cover Pump Placement
WARNING: Water on top of your pool cover poses a drowning hazard and
could damage your pool cover. Remove all water immediately. Small amounts of
water will gravitate to deeper depressions consolidating in quantities great enough
to pose a drowning potential for children and pets if not removed. If the swimming
pool has a divider wall or in-pool spa, more than one pool cover pump may be
necessary to keep the pool cover free of standing water.
The pool cover is supplied with an automatic submersible pool cover pump
designed to activate when water builds up on the pool cover. The pool cover pump
will turn on and off automatically as water accumulates and discharges from the pool
cover. Always place the pool cover pump on the pool cover when the pool cover is
closed before water accumulates. Water can accumulate on top of the pool cover
from misdirected sprinklers, overspray, holes and leaks in the pool cover, or rain,
snow and ice.
Caution: Never attempt to “dump” or remove water from on top of the pool cover by
opening the pool cover and spilling the water into the swimming pool. Attempting to
do so can damage the mechanism and the fabric.
Prepare the pool cover pump: Read and follow the pool cover pump
manufacturer’s instructions.
WARNING: Never carry or deploy the pool cover pump by the electrical cord.
Place the pool cover pump:
1. Set the pool cover pump upright on the side of the pool cover and push it
into position with a pool brush (do NOT use a metal bristled brush). Use a
pool brush to arrange the discharge hose.
Alternatively, with the pool cover over the swimming pool approximately
1/3 of the way, stand behind the mechanism and place the pool cover pump
on the pool cover. As a second person closes the pool cover, arrange the
discharge hose.
2. Assure the pool cover pump is in an upright position when set.

© Latham Pool Products, Inc. 2019. All rights reserved. 11
Arrange the discharge hose:
1. Place the hose in large “S” curves over
the surface of the cover so that it
passes through reoccurring isolated
puddles. The depression the hose
makes will help water to migrate back
to the pool cover pump for removal.
2. Assure the water that will come from the end of the hose will not flood unwanted
areas, such as window wells or the neighbor’s yard/home.
Plug in the pool cover pump:
Plug the pool cover pump into a grounded, dedicated GFCI receptacle of
appropriate voltage (see pool cover pump manufacturer’s insert).
If you are going to be away for an extended period, arrange for a competent
person to monitor your pool cover frequently and make sure all standing water is
removed. The pool cover pump can be left in service on the pool cover through the
winter months so that water is removed during thaw cycles. Insure that the power is
on the pool cover pump and the discharge hose is free of obstructions and kinks.
WARNING: Follow all pool cover pump manufacturer’s instructions. Our pool
cover pump is an electrical appliance and needs to be handled accordingly.
•Do not permit children to use this product.
•Use only for removing water from the pool cover.
•Do not use extension cords. If needed, have a qualified electrician install an
appropriate receptacle for the application of the pool cover pump.
•Do not bury the cord. Locate the cord to prevent damage from lawn mowers,
grass, hedge trimmers and other equipment.
•Replace damaged cords immediately. Contact the pool cover pump
manufacturer immediately for replacement of the power cord.
•Keep the pool cover pump in its upright position on the cover, failure to do so
can result in failure to remove standing water presenting a drowning hazard and
may also cause pump failure or damage.
•Do not run the pool cover pump without water; failure to do so may cause
damage to the integrity of the enclosure and cause an electrical short.

Maintenance and Care
 Housing Drains: Recessed system housing drains should be checked and
cleaned frequently to ensure free drainage. Debris can collect in the
recessed housing if neglected, preventing adequate drainage. Long-term
submersion of components of the system can result in substantial damage.
Long-term submersion may void warranty.
 Recessed Housing: Regular cleaning (every 3 to 6 months) and removal of
debris when necessary should be done to prevent operational problems,
damage and staining of the pool cover. Close the pool cover over the pool,
prop open the lid or remove it. Remove debris from the housing. Use gloves
and safety precautions; spiders, insects, rodents and reptiles have been
known to reside in debris in pool cover housings.
 Pool Water Level: Keep the pool water level at mid skimmer. Over- filling the
pool can result in water overflowing the lower bond beam in front of the
pool cover mechanism, flooding the recessed housing, and possibly
damaging the pool cover or causing operational problems.
 Cleaning the Top or Under Track: To clean built-up dirt, sand and debris,
open the pool cover to its fully open position. Rinse the tracks with clean
water from a high-pressure nozzle on a garden hose.
 Lubrication: Never use lubricants on the ropes, webbing or tracks.
Your Infinity 4000™ Pool Cover System is equipped with self-lubricating bearings
and does not need regular lubricating. However, dirt and debris can collect on moving
parts and may need cleaning on a regular basis to prevent excessive wear (minimum
once a year). Wash down moving components with clean water from a high-pressure
hose. Do not flood the housing and mechanism. After drying, the moving parts can be
oiled with a light coating of WD40 to drive out any residual moisture.
POOL COVER CARE
Protect Your Investment—the key to longevity of your pool cover is proper water
balance, regular care and cleaning of the fabric.
 AVOID DROWNING RISK—REMOVE ALL STANDING WATER IMMEDIATELY.
 NEVER LEAVE AN UNSECURED POOL UNATTENDED.
 REMOVE SHARP OBJECTS, POOL TOYS AND TOWELS, ETC. BEFORE
OPERATING THE POOL COVER.
 REMOVE LEAVES, INSECTS AND DIRTY WATER, ETC. AS SOON AS POSSIBLE
BEFORE THEY CAN LEAVE A STAIN OR RESIDUE.
 CLEAN THE POOL COVER OFTEN BY RINSING WELL WITH CLEAN FRESH
WATER. Rinsing often helps remove evaporated chemical solids that can
shorten the life of your pool cover (especially indoor pool covers).
 Remove difficult stains by scrubbing with a soft bristled brush, wipe with a
clean cloth, rinse and repeat. For persistent or oily residues, like suntan

© Latham Pool Products, Inc. 2019. All rights reserved. 13
lotion or stains left from debris, use a low phosphate, non-detergent cleaner,
scrub, rinse well and wipe dry. Do not use detergents on your pool cover.
 CLEAN AWAY ALGAE STAINS (PARTICULARLY BLACK ALGAE). Algae can be
found on the underside of the pool cover and can be cleaned by scrubbing
with a stiff synthetic bristle brush. Use a mixture of diluted house-hold
bleach such as Clorox regular bleach, in a ratio of 9 to 1, nine parts water to
one part bleach. Read and understand all safety-use labels.
 INSPECT THE POOL COVER FOR PREMATURE WEAR OR DETERIORATION.
 REPAIR EVEN THE SMALLEST HOLES AS SOON AS POSSIBLE. If water
penetrates the vinyl and is exposed to the scrim (the thread-like
reinforcement), the scrim will soak up water; carrying chemicals and
contaminates to the inside of the fabric. This can lead to discoloring,
stiffening and/or deterioration of the pool cover. Repair both sides of the
hole in the pool cover when possible.
 HAVE ROUTINE ANNUAL MAINTENANCE PERFORMED BY A QUALIFIED
SERVICE PERSON.
 MAINTAIN PROPER WATER LEVEL IN THE POOL FOR SAFETY AND POOL
COVER OPERATION—85% of the pool cover surface must be in contact with
the pool water to help prevent mechanical failure and to ensure safety
barrier integrity.
 MAINTAIN PROPER POOL WATER BALANCE AND PH. Long-term imbalance
or consistently fluctuating pH can ruin the vinyl pool cover in just a season
or two. Making sure the water is balanced is a top priority. Failure to do so
could result in the premature failure or wear of the pool cover and the entire
pool system.
 WITH FREQUENT USE OF THE POOL COVER, CHEMICALS REQUIRED AND
WATER USAGES ARE DRAMATICALLY REDUCED. Chemical treatments should
be adjusted to reflect a covered pool. When covering the pool for extended
periods, like winterizing, adjust automatic chemicals, feeders, salt systems
and ozone generators to appropriate levels for a covered unused pool.
 WHEN TREATING THE SWIMMING POOL FOR SANITATION OR BALANCING
PH, ALLOW THE CHEMICALS TO CIRCULATE COMPLETELY BEFORE CLOSING
THE POOL COVER. A good rule of thumb is, “Safe to Swim is Safe to Cover.”
 WINTERIZE THE POOL COVER. Maintain water level as stated above. If water
is lost through displacement by heavy snow/ice loads, water can be added
through the skimmer or under the leading edge.
 NEVER OPERATE THE POOL COVER WITH SNOW AND ICE ON IT.
 INSURE THAT YOUR POOL SERVICE COMPANY, OR WHOEVER IS IN CHARGE
OF POOL MAINTENANCE IS FULLY AWARE OF THIS INFORMATION.

Your Pool Cover and Water Chemistry
To ensure you get the maximum service and enjoyment from your pool
cover, we would like to share some pool chemistry tips that we have gathered in our
many years of business. We feel confident that if these tips are followed, you will save
a great deal of money by maximizing the life of your pool cover and minimizing your
expense for pool chemicals. Pool cover failures caused by improper water balance
and chemical damage, deterioration, premature aging, discoloration of the pool cover
etc. are not covered by your warranty.
 Obtain a good pool water test kit and use it frequently.
 Maintain good water balance (keeping the pH, alkalinity and calcium hardness
at proper levels). When your water is properly balanced it allows the sanitizing
agents, such as chlorine, to control bacteria and other contaminants at lower
levels. The result is ideal pool water. Your local experienced pool professional,
with his expertise and the instructions of various chemical manufacturers, is a
valuable resource in attaining this goal. The chemical balance of swimming pool
water is a complex subject. Total alkalinity and calcium hardness, for example,
will vary considerably from location to location depending on the area’s water
supply. Therefore, you should check with your pool builder or local professional
in identifying what values are best for your area. We have found that the
following water balance data generally works well around the country.
 Parameter Recommended Range Test frequency
pH 7.2 to 7.6 Daily
Total Alkalinity 80 to 120 ppm Weekly
Calcium Hardness 150 to 250 ppm Monthly
Free Chlorine 0.6 to 1.5 ppm Daily
Salt 3,000 ppm Weekly
*ppm = parts per million
 pH is the most important factor in the control water chemistry. The pH is the
measure of acidity and alkalinity of the water, with 7.0 being neutral. Never allow
the pH to fall below 7.0 into the acidic range. An acidic level below 7.0 creates
complex chemical interactions which are very harmful to your pool cover.
Extreme or prolonged exposure of pH values below 7.0 and/or above 7.8 can
significantly cause premature aging to your pool cover. Some pH adjusters may
create damaging levels of alkalinity (high pH) if they do not mix completely with
the pool water before closing the pool cover. The same is true of chlorine shocks;
some require up to 24 hours before a “swim safe” range can be reached.

© Latham Pool Products, Inc. 2019. All rights reserved. 16
Do not cover a pool when the water balance is not in the safe swim range; thus
the rule of thumb, “if it’s Safe to Swim, it’s Safe to Cover”. Because of the hazards of
an open pool, we recommend using a non-chlorine shock, the mixing and dispersion
of which is usually complete within 30 minutes. This allows for the pool cover to be
closed sooner. Please check with your pool service company for proper use.
•Chlorine abuse is a major cause of pool cover degradation. High concentrations
of chlorine will attack the pool cover, can bleach and discolor it, cause it to
shrink, become brittle and deteriorate rapidly. Never allow chlorine to come in
direct contact with the pool cover until it is fully dissolved and thoroughly
dispersed in the pool water. Never use floating chemical dispensers under the
pool cover.
•More is not always better: When adding chemicals to your pool; too much may
actually be harmful to you, your pool and your pool cover. This includes salt and
salt systems. Too much salt can create a “so water“ condition, particularly in
vinyl and fiberglass pools that can be extremely corrosive to the pool, the pool
equipment and your Automatic Swimming Pool Cover system.
•Extended covering: Before covering your pool for an extended period of time,
like going on vacation or winterizing your pool, ensure the water is balanced.
Recheck the water after adjusting the chemicals to make sure they have
completely mixed and dispersed through the pool. Depending on your
circulation system, this could take between 4 and 24 hours.
Please consult with your pool builder/pool service company. Have them review
the above listed recommendations and then fill in the following for your type of pool,
equipment and area.

Commonly Asked Questions
Question
Answer
Can I walk on the pool cover?
Yes, however it is recommended that you
only do so in case of emergency.
Why are there wrinkles in my pool cover. Is it
too big?
Your pool cover is custom manufactured
and tailored to your pool size. Additional
fabric is added to the pool width
measurement to accommodate the drop to
the water from the track. Also,
approximately 1% shrinkage naturally
occurs over the life of the pool cover. This
extra material also assures proper strength
of the pool cover for winterizing.
What can I do to extend the life of my pool
cover?
Keep your pool water pH in the 7.2 to 7.6
swim-safe range. Have an annual
professional service performed. Keep the
pool cover and the pool cover system
components clean.
What can I use to clean the pool cover?
Fresh water, a pool brush, and terry cloth
rags are always the first line items. Non-
detergent, low phosphate soap can also be
used. (See additional directions under the
Pool Cover Care section of the owner’s
manual.)
Should I leave the pool cover pump on the
pool cover all the time?
The pool cover pump should be placed on
the pool cover and plugged in anytime the
pool cover is closed, even during the winter
months. (See “Pool Cover Pump Placement”
section of the Owner’s Manual.)
Sometimes there is a snapping, popping
noise when I operate the pool cover. Is
something wrong?
Sometimes when the ropes are under
tension, they drop off the high side of the
rope reel and make a popping sound. This
is normal and nothing to worry about.
How soon after a shock treatment of the pool
can I close the cover?
The rule of thumb is; “if it's safe to swim,
it's safe to cover".
Follow the shock manufacturer’s
Instructions.
