To install the seal locate the word “UP”. Face
it up towards the body of the cleaner. Gently
stretch the seal over the foot pad of the cleaner
until it sets itself into the groove as illustrated in
gure 2. Once in place the seal should rotate
and move freely.
ATTACH THE SEAL
NOTE
The seal is not reversible. It must be installed
with the at side facing down towards the pool
liner and the pleated side facing upwards
towards the cleaner.

The dive oat restrictor is attached by sliding it
over the cleaner’s body as shown in gure 3. It is
fastened by sliding it over the “U” shaped locking
clip on the body of the cleaner. Make sure the
locking tabs on both sides snap securely into
place.

Your cleaner hose comes in 3’ sections which
must be connected together. The hoses are
connected by inserting the male cu of one
section of hose into the female cu of another.
Twist the sections of hose together until you
establish a snug t (See gure 5). You will need
to assemble enough sections of hose to reach
from where the cleaner connects to your
skimmer to the opposite end of the pool, plus one
section. For example, if you have a 21’ round
pool, you will need to connect 8 sections of hose
for a total of 24’ of hose.
ASSEMBLE THE HOSE
NOTE
One of the hose sections has 2 female ends.
This section should be tted last and will attach
to the pool’s vacuum connection. Save extra
sections of hose for replacements.

This is done by simply attaching the valve to
the last section of hose. The advantage of using
the valve is that it balances the ow of water
between the skimmer and the cleaner. The
valve is strongly recommended for maximum
performance, however is only necessary in
instances where there is excessive pump ow.
Excessive suction will make the cleaner move
too fast and could damage the vacuum’s
components and/or decrease the cleaner’s ability
to navigate the pool. In these instances the
automatic regulator valve must be used. This
will help restrict ow of water and make the
cleaner operate more eciently.
INSTALL AUTOMATIC
REGULATOR VALVE
NOTE
Automatic Regulator Valve must be installed
so the bypass port is always facing down and is
below the water level.

To install the eyeball diverter remove the
original eyeball from the r eturn by unscrewing the
lock ring. Replace the original eyeball with the
cleaner eyeball diverter. Replace the lock ring
and tighten. The best way to position the eyeball
diverter is so the ow is directed downward.
This will help eliminate the return ow from
interfering with the cleaner.

Your automatic pool cleaner is designed to work in a wide variety of swimming pools.
There are items that may or may not be needed to be installed for your cleaner to function
properly. All installations are covered in this manual. Find which type of installation
matches your pool conguration and follow the instructions carefully.
For the cleaner to work properly, regardless of the installation type, the hose needs to be
completely primed. The easiest method of priming the hose is to simply put the end of the
hose up to your pools return tting (eyeball) with the pump running. The pump will force
water through the hose and purge all of the air out. Keep the pump running until there are
no air bubbles coming out the opposite side.
Once fully assembled,
your Automatic Pool Cleaner
should look like this.......

This is the most common type of installation.
This type of skimmer is provided with a vacuum
plate that ts over the skimmer basket. The plate
has an elbow. Place the end of the Automatic
regulator valve over the elbow. Make sure that the
bypass post on the valve is facing down.

The skimmer provides a vacuum port in the
skimmer face plate below the skimmer opening.
With this type of skimmer simply insert the end
of the automatic regulator valve into the vacuum
port.

For skimmers that do not use a vacuum plate.
Attach the end of the automatic regulator valve
into the 2” hose cone. The 2” hose cone is then
inserted into the bottom of the skimmer
NOTE
Make sure the cone ts snugly inside the
bottom of the skimmer.

You may also need to attach hose weights to neutralize the hose’s buoyancy in the water.
For aboveground pools with the at bottoms, typically one weight is needed. It should be
placed on the rst section of hose, between 4 to 12 inches away from the body’s swivel
head. Complete the hose assembly by attaching the rst section of hose to the cleaner
body.
With the cleaner o, the hose balance is correct when the cleaner’s seal rests at on the
pool oor and the main body makes a 45 degree angle with the pool oor. The cleaner will
achieve the best performance when the hose neither weighs down or pulls up the unit.
Adjust the weights one inch at a time as needed, until the proper hose balance is achieved.
• HOSE IS TOO LIGHT — If the hose rises towards the surface at an angle greater than
45 degr ees, move the weight closer to the cleaner .
• HOSE IS TOO HEAVY — If the hose sags downward at an angle less than
45 degr ees, move the weight away from the cleaner.

• For pools with 2 suction lines (i.e. main drain and skimmer or 2 skimmers) it is
necessary to close o the suction line not being used for the cleaner. This can be done
by turning o the valve for the main drain, or using a skimmer bypass plate to restrict
the ow of water.
• As your vacuum cleaner removes debris from the pool and it is collected in your lter,
you may notice the vacuum operating slower than normal and a reduction in ow from
the return. Make sure that you periodically check your lter pressur e and backwash
your lter or clean your lter element as needed.
•Remove as many obstructions as possible including ladders, oats, or any other items
that may be in the pool and could limit the cleaner’s ability to navigate the pool.
• Do not coil hose when taking the cleaner out of the pool. The hose may retain the
shape, forming a bend or kink which will hinder the cleaner’s performance.

Remove your vacuum from the pool and dry completely. Disassemble the hose sections
and store in the original box, or lay the hoses out on a at surface. NEVER store the hose
in a coiled position as it may retain the curved shape, not allowing the vacuum to operate
efciently. Store the vacuum so the pleated seal lays at, or remove the seal and store it in
a at position. Store all parts indoors.

Sometimes debris may clog the bottom of the cleaner and prevent the apper from
moving. This will restrict the ow of the cleaner. The apper is located inside the main
body and must move freely at all times. You can see the apper through the opening in the
bafe plate when the cleaner is turned upside down. Try to free the apper by moving it
back and forth, or ush the cavity of the cleaner free with a garden hose. This will r emove
any debris that may be lodged inside the cleaner.

7
If debris is still lodged inside the cleaner, you must remove the apper. To do this you
must take out the four red plugs in the foot pad. These are found on the bottom of the
cleaner. They can be removed using a at head screwdriver. Underneath there will be four
screws. Unscrew them and remove the foot pad from the main body. Once removed
there is a plate. Remove the single screw from this plate and slide it out of the main body.
This will expose the apper and it can be pulled out.
Remove any debris that may be inhibiting the apper. Once dislodged insert the apper
back into the body. Slide the plate back into position and re-screw it into place. Then
re-install the foot pad. Make sure that all are securely in place.
