Speck pumpen BADU Picco Instructions De Montage Et D'utilisation page 13

The motor shaft also serves as the pump shaft on which the impeller is moun-
ted. The seal for the shaft is a bellows-type mechanical seal arranged on a pla-
stic impeller hub. This guarantees positive electrical separation between the
pool water and the electric motor. Because of the pump's close coupled design,
a minimum of space is required. The pumps are driven by A.C. motors. Integra-
ted in the pump housing is a strainer basket (143) which keeps coarse impuri-
ties from the pump's interior.
5. Placement / Installation
5.1
CAUTION
The pump is equipped with a motor protection type IP X4. In case the pump is
installed outside, we recommend nevertheless to see for a simple rain
protection. This will increase the durability of your pump. When installed in a
closed room, like for example a cellar a drainage connected to the sewers must
be foreseen. If the pump is installed in a humid space, effective ventilation and
aeration must be provided for, in order to prevent condensation. In case of very
small installation spaces, the natural cooling of the air may be so insignificant
that, also there, ventilation and aeration is necessary in order not to exceed the
environmental temperature of 40°C.
Make sure, by applying appropriate measures, that the environment will not be
impaired by any sound produced by the pump.
During installation, make sure that there is enough space available to permit
subsequent disassembly of the motor unit in the direction of the motor fan (mi-
nimum 90 mm) and of the strainer basket (143) towards above (minimum 140
mm), see directions in the dimensional drawing. Fastening the pump to the
foundation should be effected exclusively by means of bolts, threads or
dowels in order to avoid blocking the removal of the motor unit! Inlet- and
outlet-pipes must be mounted to the pump housing free of tension.
5.2
CAUTION
Mechanical / Hydraulic
The pump must be installed in a horizontal position in dry condition. It may be
installed either max. 3 m below (gravity feed) or 1,5 m above (suction mode) of
the water level. Thereby the geodetic head between liquid level and pump inlet
must not exceed 1,5 m. The suction lift may be significantly reduced by flow re-
sistance in the suction line, if the pipes are very long and/or insufficiently di-
mensioned. Make sure that the suction line is not leaky, otherwise the
pump will prime insufficiently or not at all. The transparent lid as well as the
ring nut must be screwed on tightly and the suction/intake line should be as
short as possible. This will reduce priming time which is dependent on the air
volume in the intake line. If the intake line is very long this may take up to 12
minutes. If possible the intake line to the pump should be installed below the
water level. Whenever the pump is installed above the water level it is recom-
mended to install a foot valve in the intake line. Thus the intake line cannot
drain itself while the machine is shut down. This keeps priming times short e.g.
after cleaning of the strainer basket (143).

5.3
Electrical: All electrical connections should be performed by a qualified
expert only!
Please make sure that the electrical installation has a disconnecting device
which allows disconnecting from the power supply with a minimum of 3 mm
contact gap at each pole. This pump is built according to Protection Class 1.
The ambient temperature must not exceed max. 40°C. Pumps with A.C. motors
are equipped with a winding breaker contact as standard.
The motors are built according to isolation class F, the ribs may achieve tempe-
ratures up to 70°C.
Caution: The use of pumps for swimming pools and the restricted area
around them is only permitted if pumps are installed in accordance with
DIN/VDE 0100 part 702. Please consult your licensed electrician!
The supply circuit has to be protected with a fault current contactor with a
nominal fault current of I ≤ 30 mA.
∆N
The electrical wiring used (HO5RN – F for inside, HO7RN – for outside) must
have a minimum cross section of 1 mm
5.4 Opening of the terminal box cover:
1. It is important to first lever the 4 locking pins (a) loose by using a screwdri-
ver, push them up by hand (approx. 10 mm) until limit stop (see drawing 1).
Caution: Don't use any force, don't tear the safety pins out!
2. Lever the 4 cams upwards by putting a screwdriver into the slot (c) (see dra-
wing 2).
3 Lift terminal box cover vertically (see drawing 3).
Closing of the terminal box cover:
1. In order to avoid any damage to the filigree sealing lip (b) put the cover ca-
refully and right-angled onto the housing and push it down.
2. Only when the cover is fitted perfectly to the housing, push the locking pins
(a) until they catch.
