Pool vacuum systems:
how they work, keeping them maintained and fixing problems
When you
purchase a vacuum unit for your pool, make sure you read and
understand the directions for setting up, utilizing and maintaining
your equipment. Also make sure you understand how it works as this
will help you get the most satisfaction from your vacuum and help to
keep your pool clean and free from debris.
Vacuum units contain a bag to shift the dirt and debris away from
the swimming pool. The pressurized water from the booster pump
forces the end of the vacuum to sweep back and forth and the vacuum
loosens dirt at the bottom of the pool. The pool's circulation
system then filters out the dirt. In order for the vacuum unit to
work properly, pressurized water from the booster pump enters the
unit through the stem while some of the water is forced out at the
end.
Some of the water is responsible for powering a turbine engine that
has a horizontal shaft with gear teeth which moves other gear teeth
on the inside of a left-side wheel and right-side wheel on the
front. After that a little right-side wheel moves power to the
larger right-side wheel, which causes the unit to move forward. This
operation causes some of the water that was to be redirected to the
power jet; The head float helps keep the unit upright, and the power
jet may be adjusted up or down in order to assist in keeping the
unit from moving nose-up.
Installation Vacuum Sweeps can be purchased as over-deck units or as
pre-plumbed models. The over-deck models need a garden hose to
operate it. The garden hose runs from the equipment over the deck to
the edge of the pool. With the pre-plumbed unit the pipe from the
equipment is plumbed into the original pool plumbing to the pool. On
both of those types the booster pump and vacuum units are the same;
it is merely the plumbing that is different. Read the installation
instructions carefully before installing your unit.
In order to keep your automatic pool cleaner operating at peak
condition always operate the booster pump along with the circulation
pump. The booster pump depends on the system circulation pump to
supply water because it is not self-priming. The pump, which is
composed of plastic, will overheat and could burn out if the booster
pump runs dry.
In order to keep the components from wearing out, set the time clock
on the booster to come on at least one hour after the circulation
pump does, and also to go off at least one hour prior to the
circulation pump. It will take approximately three hours for the
vacuum head to cover most of the pool.
The next step is to set up the catch bag. This bag will trap the
fine dirt and sand, but you need to make sure that the openings on
the bottom of the bag and through the center of the bag do not
contain leaves which will clog it. You need to maintain a clear path
so that the debris may get into the bag. Also be sure to empty the
bag as needed.
