6.5. Electrical connection
OFF
Electrical connection must be carried out only
by a qualified electrician in accordance with
local regulations.
Follow
safety standards
EN 60335-2-41, EN 60335-
2-60 or UL 1795 and UL 1081and adopt all safety
measures indicated in installation standards.
The unit must be properly earthed (grounded).
Connect the earthing (grounding) conductor to the
terminal with the marking.
Compare the frequency and mains voltage with the
name-plate data and connect the supply conductors
to the terminals in accordance with the appropriate
diagram inside the terminal box cover.
ATTENTION: never allow washers or other
metal parts to fall into the internal cable
opening between the terminal box and
stator.
If this occurs, dismantle the motor to
recover the object which has fallen inside.
The flexible power supply cord must be at least of the H05
RN-F or H05 VV-F type. For outdoor whirlpool or spas the
mains cable must be at least of the H07 RN-F type with
section of cable not less than (par. 12.5 TAB 1).
All the electrical components must be located outside
the reach of individuals who use the pool and must be
positioned or attached without any risk of their falling
into the bathtub.
Make electric bonding connections.
Connect only to a circuit protected by a ground-fault
circuit-interrupter with a rated residual operating
current I∆N not exceeding 30 mA.
Install a
device for disconnection from the mains
(switch) with a contact separation of at least 3 mm in
all poles.
With a three-phase motor install an overload protection
device with curve D appropriate for the rated current
of the pump.
Single-phase
SPAM
, are supplied with a capacitor
connected to the terminals and (for 220-240 V - 50 Hz)
with an incorporated thermal protector.
7. STARTUP AND OPERATION
7.1. Preliminary checks before start-up of the
pump
Do not start-up the device in case of damaged parts.
7.2. First starting
OFF
ATTENTION: never run the pump dry, not even for
a short trial run.
Start the pump when the bathtub has been filled.
Stop the pump before the bathtub is drained.
To avoid damage to the pump due to prolonged
operation in a no-water situation make sure the
installed unit has level detectors or sensors to impede
starting and to provide automatic stopping if there is no
water in the bathtub or install a timer to protect against
the risk of prolonged accidental operation.
At first start-up or following a long idle period
,
check that the shaft turns by hand.
For this purpose use the screwdriver notch on the shaft
end ventilation side. Turn the shaft by hand only in the
direction indicated by the arrows on the pump casing.
Note that a slight degree of resistence to rotation is
normal; this is due to friction caused by the mechanical
seal.
The pump might be jammed by an obstruction, foreign
matter, sticking of mechanical seal surfaces or other
causes.
If the shaft cannot be freed by hand, the pump will
have to be dismantled and cleaned.
With three-phase motors check the direction of
rotation.
Do not start the motor if the shaft is jammed.
If
jammed, the impeller may unscrew should the
motor start rotating backwards
. Reverse rotation
can also damage the mechanical seal.
Momentarily start the motor
to make sure pump
shaft rotation corresponds to the direction indicated by
the arrows on the pump casing: rotation is clockwise
when viewing the shaft from the fan end.
Otherwise, disconnect electrical power and reverse
the connections of two phases.
Never drop or insert any object into any opening.
Do not operate this unit without the guard over the
suction fitting.
7.3. Switch off of the pump
ON
The appliance must be switch off every time
there are faults. (see troubleshooting).
The product is designed for a continuous duty, the
switch off is performed by disconnecting the power
supply by means the expected disconnecting devices.
(see paragraph “6.5 Electrical connection”).
8. MAINTENANCE
Before any operations it's necessary to disconnect the
power supply.
If required ask to an electrician or to an expert
technician.
Every maintenance operations, cleaning or
reparation executed with the electrical system
under voltage, it could cause serious injuries
to people.
If the supply cord is damaged, it must be
replaced by the manufacturer, its service agent
or similarly qualified persons in order to avoid
a hazard.
In case of extraordinary maintenance, or maintenance
operations that require part-removing, the operator
must be a qualified technician able to read schemes
and drawings.
It is suggest to register all maintenance operation
executed.
i
During maintenance keep particular attention in
order to avoid the introduction of small external
parts, that could compromise the device safety.
It is forbidden to execute any operations with
the direct use of hands. Use water-resistant,
anti-cut gloves to disassemble and clean the
filter or in other particular cases.
i
During maintenance operations external
personnel is not allowed.
Maintenance operations that are not described in
this manual must be made only by special personnel
authorized by Calpeda S.p.A.
For further technical information regarding the use or
the maintenance of the device, contact Calpeda S.p.A.
8.1. Routine maintenance
OFF
Before every maintenance operations
disconnect the power supply and make sure
that the device could not accidentally operate.
