instructions carefully.
Please read the instructions (14) carefully
before installing or using this equipment.
DANGER risk of electrocution.
Take all precautions when working on the
equipment, for it is connected to the mains
and contains water (a very good conductor of
electricity).
When approaching any work on the pump, it is
essential to switch off the electricity supply.
DANGER power-supply cable
Place the power-supply cable in such a way
that it cannot be walked upon, perforated or
damaged by any object in its vicinity.
Carry out the installation in accordance with
the safety recommendations for swimming
pools and the specific instructions for the
pump to be installed (not provided with the
equipment).
Current safety regulations must be complied
with when installing the equipment.
FORBIDDEN to work upon or repair.
Work or repairs must be carried out only by
official technical service centres.
Users can only carry out the work described in
this manual.
The manufacturer declines responsibility for
any work that may be carried out by the user.
IMPORTANT NOTE: cleaning.
Always clean with a cloth moistened with a
neutral soap solution. Do not use products
containing solvents or acids.
Do not run the pump dry; the swimming pool
water must cover the plate entirely.
GENERAL CONSIDERATIONS. 2.
Introduction. 2.1.
The swim-against-the-current unit is a piece of
equipment for swimming pools that propels a large
jet of water by means of an electric pump.
It is used for practising swimming against the
current.
As an option, and by using a massage hosepipe
(not supplied), it can have the function of propelling,
together with the water, microbubbles which in
contact with the user’s body provide a pleasant
sensation with hydrotherapeutic effects.
It is available with a round or square plate and
the possibility of fitting three different versions of
wallmounted pump-control panel, depending on the
power supply or the power of the electric pump to
be installed.
Main functions. 2.2.
Propulsion of water: with built-in manual a)
adjustment of water-jet flow and direction.
Propulsion of air bubbles: built-in control of b)
bubbles by choking off the passage of air, which
by venturi effect is propelled simultaneously with
the water jet.
Pump Stop/Start switch: fitted with a pneumatic c)
push-button, which for reasons of electrical safety
remotely actuates the pneumatic switch on the
control panel, thus stopping or starting the electric
pump.
