Circuit description.

F. The absorbing circuit takes the water by means of the sumps and takes it to the jets.
This circuit is controlled by the massage pump.
G. The water-impulsing circuit returns the water at a high speed to the spa, that combined
with the venturi circuit, provides an air-water massage. The return is effectuated
through the jets, distributed throughout the Spa.
H. The returning circuit returns the water to the Spa that goes through the filter and
heater keeping the water ready both in the filtering and heating periods.
I. The Skimmer or overflow absorbing circuit takes the water into the Spa through a
return inlet. This circuit is controlled by a filtering pump, going through the filter, the
heat exchanger and the compensation deposit in public-use spa.
J. The air circuit impulses air from the air pump to the Spa. The water distribution inside
the Spa is effectuated by means of nozzle bodies, placed at the bottom or on the seats
of the Spa.
Note: It is essential to create a trap of 150 mm above the maximum level of water and
place an antireturn valve between the trap and the Spa.
Spas with overflow have a compensation deposit with a double function:
Absorb the water in excess resulting from the entry of bathers into the Spa.
Avoid the filtering pump to remain empty of water.
For a proper location of the deposit it will be installed as near as possible to the Spa, under the
floating level so that the overflow can eliminate all the incoming water.
The absorbing pump input must be placed under or at the same level of the compensation
deposit bottom.
The compensation deposit has a general water entry with an electro valve (not included) that
opens when tension arrives and a drainage of 50 diameter located at the highest point of the
deposit.
