ALL-WEATHER JUNCTION BOX*
*Supplied by electrician
* The HOT (black) wire from the power supply connects to the L1 terminal on the switch.
* The NEUTRAL (white) wire from the power supply connects to the indicator light and also passes
through to be connected at the motor conduit white wire.
* The remaining wire on the indicator light connects to a directional terminal on the switch (A1 or A2).
* Using a test cord, disconnect wires
in the all weather box and connect
the neutral wire to the white motor
wire and connect the hot wire to
the red motor wire. The motor
should run. Then switch the hot
wire over to the blue motor wire.
The motor should run in the other
direction.
If the motor runs in both directions
using this method, the trouble is
in the components or wiring leading
up to that point in the system. If the
motor still does not run properly, you
may need to investigate the
capacitor inside the control box
mounted on top of the motor.
* The Red and Blue wires from the motor connect to the directional terminals on the switch.
(A1 and A2) The red and blue wires may be switched with each other to change the motor direction.
* The motor requires 8.5 amps and all wiring from the power supply to the motor must be si zed accordingly.
* Use a 15amp GFCI breaker at the panel.
* The motor capacitor is located inside the motor control compartment on top of the motor.

Coverstar safety covers: UL and ASTM standard F 1346-91 for safety covers for swimming pools
All Coverstar covers fully certified by UL and meet the ASTM standard for safety covers as specified in
ASTM standard F 1346-91 when they are installed and maintained properly according to the installation
and homeowner instructions which have been provided by Coverstar. On several different occasions, the
Coverstar covers, both automatic and manual have been tested by independent testing laboratories and
have always been found to be in compliance with all the ASTM requirements for safety covers. Our cover
is also listed by UL (File E164833) and classified by UL as a power safety cover in accordance with
ASTM F 1346-91
If you wish to verify either of the UL certifications, take the following steps:
Go to www.ul.com
Once there click on Search UL.com
Click on Online Certifications Directory.
Under General Search click on UL File Number
Type in E164833 and hit enter
You should now see Coverstar’
s listings. If you have problems, you can also search by company
or by Automatic Pool Covers
If more information is required about ASTM and its standards, you can go to their website at
www.astm.org.
Shown below is the UL authorized label that is attached to the automatic cover system that we ship.
If you have any further questions about our covers, the UL certifications or the ASTM standards, please

MOTORIZED COVER WINTER USE POLICY
The question is often asked, “Do you recommend using the motorized cover (ECLIPSE) as a winter cover?” The answer is
that it is a matter of personal choice. We neither recommend nor discourage use of the motorized cover as a winter cover.
We are neutral on this issue. In order to help you make a decision, we have listed below some of the items you should
consider when making your choice.
1.
When proper precautions are taken, motorized covers are successfully used as a winter cover.
2.
During the winter the proper water level must be maintained as the water supports the ice and snowmelt buildup. The best method is to blow out the lines and use filter plugs & cover plates so that the water level does
not have to be lowered. In no case should the water level be lowered more than 6 inches below the track.
3.
The cover pump must be left on the cover and plugged in, so that as water accumulates from the ice and
snow melting, it will be pumped off of the cover. Excessive amounts should not be allowed to build up
on top of the cover. Attempting to break and remove snow, or ice from the cover can cause damage to
both the cover itself and the tracks. The cover should never be operated if it has water, snow or ice on it.
4.
There are some risks associated with using the motorized cover as a winter cover, such as the water level
dropping below the recommended level. If the pool loses water because of a leak or for any other reason,
there may not be enough support for the cover. This could cause the tracks to pull down, possibly damaging
the material to which it is attached as well as the cover itself. However, if there is adequate slack in the cover
and the water level is properly maintained, there is little likelihood of problems occurring.
5.
The cover is not warranted against damage to the cover or pool due to winter use, just as the warranty does not
cover damage due to such things as mudslides, earthquakes, falling trees, etc.
6.
Leaves and debris should be removed from the cover as they accumulate to avoid damage and staining the
cover.
7.
A cover should only be used as a winter cover if it has the proper slack. Proper slack is determined by where
the cover touches the water. When the water level is lowered, the cover should normally touch the water no
more that 12 inches from the edge of the pool. Actual slack requirements may vary depending on local
conditions.
8.
Another consideration has to do with the longevity of the cover. The cover will not last as long when used as
a winter cover because of added exposure to the elements. If it is not used as the winter cover, it should be
cleaned and rolled up during the wintertime.

SLACK IN AUTOMATIC POOL COVERS
From time to time the question arises about the need for slack in automatic
pool covers and how much is enough. Regardless of manufacturer, all
automatic pool cover fabrics are made wider than the width of the track.
There are several reasons for this:
1. A cover that is too tight will pull against the tracks and will not
operate properly. A cover that is made too small reduces the life of
the cover and mechanism, causing premature failure of both the
fabric and the mechanism due to the added stress.
2. All fabric shrinks over a period of time. The amount of the
shrinkage varies widely according to the type of fabric, how the
fabric is manufactured, the temperature of the water, and the
weather conditions. Slack is added to the fabric to compensate for
fabric shrinkage.
3. The cover must lie on the water in order to meet he ASTM safety
standards. Most of the supporting strength of the cover comes
from the support of the water directly under it.
Each cover we manufacture is made with the sack calculated on the basis of
the type of fabric, application and unit. Any other variables that may be
brought to our attention are also included. Initially, a properly sized cover
will drop almost directly down from the track or deck to the water, with some
folds & wrinkles as it crosses the pool. Because each cover is subject to many
variables, it is impossible to calculate the exact amount of shrinkage each
individual cover will have, so an approximation is made based on our past
experience. Our slack formula is designed to give the cover and mechanism
maximum life, as well as making the cover look as attractive as possible.
Before an order for any cover which has less that the factory specified slack is
processed, we must receive a signed statement from the customer which
releases Coverstar from any warranty or safety liability issues which may
arise because of premature failure of the fabric or system due to fabric
shrinkage.
In some cases, a portion of the slack may be taken up by lowering the water
level. However, you should consult with your pool builder or service man
before doing so. They can advise you exactly where the water level should be
to keep the pool equipment operating properly.
The slack in the front of the cover must be spread over the length of the
leading edge, keeping it away from the sides near the tracks. If this is not
done, it is possible that the fabric may fold over and get caught in the track.
The leading edge loop size has been designed to give maximum flexibility in
properly installing and servicing the cover.
