The premises in which the pump is installed
must comply with the complementary technical
safety instructions applicable to damp or wet
premises.
The premises must be provided with a drain
that allows water to be evacuated in the event
of flooding of the premises that might be
detrimental to electrical safety and cause injury
to persons.
For optimum pump operation and reliability the
premises must be provided with a ventilation
inlet.
The installation pipes and accessories must be
made of PVC. Under no circumstances must
iron pipes or accessories be used, as they
could damage the plastic components of the
installation.
c) Electrical wiring.
The wiring must be in accordance with EEC
standard or of type H07 RN‑F according to
VDE 0250.
The electrical trunking must be watertight,
and connections and their fittings must have a
sufficient degree of protection against vertical
fall of water drops. Connections, trunks and
branch connections must always be housed in
leaktight boxes.
Installation and assembly must be entrusted to
an authorised installer.
3.8. Start-up.
Once the connections have been made and before
running the pump the leaktightness of joints must
be checked. Switch on the water supply to the pump
and eliminate any air left inside the pump by using
the bleed devices on the pump.
Start up the pump. Press "Start" on the electrical
panel (8) and press the pneumatic pump‑start
button.
The pipe valves must be fully open during
pump operation and must never be closed
while it is running. Shutting off or quickly
reducing the passage of water can give rise to
pressure surges that could lead to equipment
breakage.
Leave the pump running for a few minutes and
check that the equipment has been correctly
installed.

4. INSTRUCTIONS FOR USE.
4.1. Starting / Stopping the pump.
The pump will come into operation when the
pneumatic pushbutton is pressed, and will stop if it
is pressed again.
4.2. Air regulator.
With the hydromassage hose connected, turn the
regulating button to regulate the air bubbles.
Keep air passage closed if the massage
hose is not in use.
Note: The hydromassage hose is
an accessory not supplied with the
equipment.
4.3. Flow regulator.
The water flow can be adjusted by turning the
discharge pipe to the right or to the left.
The direction of the water jet can also be adjusted
using the discharge pipe knuckle‑joint system.
5. REPAIR AND MAINTENANCE.
5.1. General considerations.
Check the air-passage filter (9) and if necessary
clean out any dirt or insects.
5.2. Overwintering.
The installation must be protected in winter
against the potential risk of freezing. The following
operations will have to be carried out:
– Disconnect the pump from the electricity supply.
– Remove the front plate (6) and the capillary
pipe (7) of the pressure switch and stow them
away.
– Drain the water from inside the pump, using the
drain plug. (Fig. N)
– Fit the protective cover (4).
After the overwintering period refit the components
removed and, before running the pump:
– Check manually to ensure that the pump motor
shaft rotates, by rotating the fan.
– Check the connections for leaktightness.
Correct operation of the installation must be
checked during the first few minutes of running.
