Return Line Adjustments

Important

The cleaner must move randomly throughout the pool. Water circulating at the surface
will infl uence the hose thus limiting Cleaner’s coverage.

Adjust Return Line Flow as described in diagrams below.
To adjust the Eyeball Diverters;
loosen the lock ring and redirect the Eyeball Diverters slightly downwards and also

try different directions to see what works best in your pool. allow time for the body
of water to settle into new pattern.

Hose Assembly & Weights

Important

The exclusive three-year warranty is only
valid if the machine is operating with
genuine Hammer Head hose.

N.B. Hammer Head hose is specially
constructed for optimum performance
and is protected by a three-year warranty
against factory defect.

Twist and push the female ends to the
male after dipping the ends into the pool to
wet them. Push until the hose fi ts snugly.
Do not force the hoses on, as this will
hamper dismantling. Continue until you’ve
connected all the sections you need.

The Hammer Head hose sections which
must be assembled by connecting together
as many hose sections as needed to reach
from the skimmer/weir to the farthest point
of the pool, plus one section or plus two
sections if your skimmer/weir is located at
the center of your pool.

N.B. The leader hose will be considered the
extra length hose needed to reach from the
weir to the farthest corner. As this hose is
connected to the pool cleaner.

Hose must equal longest stretch

plus one

length

8

Installation

Ensure the pump and fi ltration system is switched
off before commencing.

Insert the weir adaptors into vacuum lid.
Connect the already measured out hose sections

to the Hammer Head.

1. Insert Flow Gauge into leader hose.

2. Place hose lengths into pool (fi lled with water) and
connect to regulator valve fi tted to weir.

3. Switch on pump and regulate fl ow of water

IMPORTANT: The Flow Gauge is used for test purposes
only and must be removed during normal operation of the
Hammer Head

Switch the pump on and start adjusting the Knob
of the Regulator Valve “Faster” or “Slower” until the
disc indicator in the Flow Gauge settles between
“maximum” and “minimum” fl ow.

Turn the pump off.
Remove the Flow Gauge and connect the pool

cleaner to leader hose.

NOTE: optimizing the water fl ow does not mean
maximizing the fl ow through the Cleaner. In fact, to
insure a random pattern of travel that will enable the
Cleaner to reach all areas of your pool, it is better to
use less suction, not more.

Switch on your pump.
Your fully assembled Hammer Head will start
pulsating immediately.

Balancing the Hose

You will also have to attach hose weights to the hose to neutralize the hose’s
buoyancy in the water. Hose weight is not required for most of the pools.

To improve cleaner’s pool coverage place 1st hose weight between the 3rd and
4th hose and the 2nd hose weight between 4th and 5th hose from the cleaner.

Hose Weights

Hose Weights

Fine Tuning

The water density in each pool may vary due to mineral and salt content.
To fi ne-tune the balance of your hose, try moving the 1st hose weight closer

towards the 2nd hose weight to improve cleaner’s pool coverage.

10

Maintenance

Your Cleaner requires very little maintenance.
Check the Flapper from time to time.

1. It is quick and easy to open up the Flapper’s
chamber. Simply stop the pump, push the sliding
lock up into open position and remove the lid. With
your fi nger lift and inspect the Flapper and the
chamber to insure that it is not obstructed by debris.
See picture:

2. Place the lid back and slide the lock down to close.

3. Remove damaged or worn Flapper; no tools are
required. Simply grab the Flapper, pull and waggle
outward until it unclips from the steel pin. To install
the new Flapper push it in fi rmly onto the steel pin
until it snaps in place. If the Flapper is clipped in
the wrong way you will not be able to close the lid.

11

Maintenance

• Check the Suction Seal for wear. If it becomes thin and too fl oppy, it will impair the

correct random movement of the pool cleaner and should be replaced.

• Check the footpad. It is a wearing part and should be replaced when worn.

• Inspect the Regulator Valve and fl ush away any debris build up.

• Clean your fi lter system.

• Empty the Skimmer Basket.

• Empty the Strainer Basket.

• Use your Flow Gauge to insure correct water fl ow for your Cleaner.

• For best results and to maintain proper operation, use only original hoses.

NOTE: Remove the Hammer Head pool cleaner from the pool before the chemical

shock treatment! When not in the pool, keep the Hammer Head pool cleaner’s
Suction Seal fl at to avoid warping.

• When people are using the pool, disconnect the Cleaner and pull it to one

side of the pool.

• When storing or winterizing the Hammer Head, do not coil the hose. Lay the hose

fl at in an area protected from direct sunlight. It is also important to remove the
Suction Seal from the Hammer Head and store it fl at.

• Leaf catcher - If your pool is exposed to large quantities of leaves, we suggest

purchasing and installing a leaf catcher. a leaf catcher will provide more debris
loading capacity and also provides a water by-pass when the leaf bag is full.
It is very important that the pump will not starve for water!

Trouble Shooting

Problem: Cleaner is sluggish or has stopped operating.
Solution: • Check Hammer Head for blockage inside the Oscillator chamber.

• Clean your fi lter system, empty pump basket and empty skimmer/weir
basket.

• Clean cartridge inside cartridge fi lter, if one is installed.

• Inspect the Regulator Valve and fl ush away any debris buildup.

• Check the footpad under the Hammer Head for wear.

• Make sure the curved tips of the suction seal is facing upwards.

• Ensure that the skimmer/weir vacuum lid is fi tted correctly and check for
cracks.

• Check the hose for blockage.

• Check the hose for leaks by lifting each section above water while pump
is running.

• Using your Flow Gauge, verify proper water fl ow to your Cleaner.

• Backwash and rinse system.

• Run your sand fi lter on bypass/circulate. If Hammer Head performs
better, consult a pool shop in your area.

Problem: Cleaner gets stuck on steps.

Solution: • Adjust the Eyeball Diverter of the return fl ow towards the problem area

to guide the Cleaner away from the steps.

• Verify proper hose length and correct position of the Hose Weights.

• Remove or add one hose section.

• Using your Flow Gauge, verify proper water fl ow to your Cleaner.

• Using your Flow Gauge, Increase or decrease the fl ow to your cleaner
with-in the maximum/minimum range by adjusting the valve.

• Check the footpad under the Hammer Head pool cleaner for wear.

Problem: Cleaner travels in a repetitve pattern.
Solution: • Adjust Eyeball Diverters downwards.

• Verify proper hose length and correct position of the Hose Weights.

• Remove or add one hose section.

• Using your Flow Gauge, verify proper water fl ow to your Cleaner.

• Inspect the Regulator Valve and fl ush away any debris buildup.

• Check that the hose sections are straight; if not straighten up the coiled
hose and lay it in the warm sun for day or two.

• Ensure the swivel on top of the Hammer Head pool cleaner is rotating
freely and is screwed on securely.

13

Trouble Shooting

Problem: Cleaner does not stick/climb onto the wall.
Solution: • Using your Flow Gauge, verify proper water fl ow to your Cleaner.

• Increase the water fl ow slightly, by adjusting the valve to faster.

• Verify proper hose length and correct position of the Hose Weights.

• Ensure the radius from the fl oor to the wall is not too small. If so, you have
what is termed a “Square bottomed pool” – in which the Hammer Head is
unable to climb the walls.

Problem: Cleaner climbs out of pool and draws in air.
Solution: • Ensure there is a valve installed in the skimmer/weir.

• Using your Flow Gauge, verify proper water fl ow to your Cleaner.
