3.7. Fitting the pump
Pump installation and assembly must be carried
out by an authorised installer.
a) General safety warnings.
The equipment must be fitted following
current safety regulations for installing
swimming pools, and particularly standard
IEC 60364-7-702 and the special regulations
for each application.
The pump must be installed on a flat surface
and attached to the floor.
To ensure the safety of persons, the pump
must be installed at least 3.5 metres from the
swimming pool.
The mains electricity supply must be protected
by an automatic power-supply cut-out device,
a residual current circuit-breaker switch (Δ fn)
not exceeding 30 mA.
b) Fitting the pipes.
(Fig. O)
The connection pipes to the pump for distances
of up to 3.5 metres must have a minimum
diameter of DN63. For distances of up to 5
metres from the swimming pool piping of DN75
must be used, and DN90 piping for distances of
more than 5 metres.
Flow valves must be fitted in the discharge and
suction pipes, so that the pump can be removed for
maintenance without draining the swimming pool.
Particular care must be paid to ensure that
water cannot enter the pump motor or other
electrically powered parts of the installation.
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.
(Fig. P)
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 (Fig. Q)
The pump will come into operation when the
pneumatic pushbutton is pressed, and will stop if it
is pressed again.
4.2. Air regulator (Fig. R)
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. (Fig. S)
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. K)
– 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.
IMPORTANT INFORMATION:
Your Davey pump is
Double Insulated to Water Circuit. If equipotential bonding
structure is required, then a Equipotential Bonding Point
is provided. (Please refer to your local statutes and
regulations for AS/NZ 3000 Wiring standards).
