5. ELECTRIC CONNECTION:
- The electric connection must be carried out by a
qualified electrician.
- Single phase pumps equipped with capacitor must be
connected as shown in fig. 2.
5.1. EARTH CONNECTION
- The pump must be earthed before any
other operation, even if the delivery pipe is
a non metallic one.
- The earth connection is also useful to reduce the risk
of galvanic corrosion due to electrolytic action
especially with non-metallic delivery pipe and safety
rope.
5.2. RESIDUAL CURRENT PROTECTION
DEVICE:
- It's advisable to install a height capacity
switch (0,03 A) with complemental
protection against electric discharges in
case of ineffective earthing.
- Make sure the frequency and mains voltage
correspond with the pump data;
- The electric connection must include a multipolar
switch or other disconnection device from the mains
with a minimum contact separation of at least 3mm
on every polles.
5.3. AquaRain 230V:
- Single-phase pumps are suplied with an incorporated
capacitator and a thermal protector so that the motor
will stop if overheating is detected and with automatic
start up (after cool down 2 to 4 minutes).
5.4. AquaRain 400V:
- Three-phase pumps must be connected to the power
supply line through a control box equipped with:
- water level protector with its respective electrodes
to prevent the pump against dry runnig;
- frequency protetor against phase lack;
- Thermal protector gauged for the motor mains
voltage.
6. STARTING:
- Never run the pump dry, not even for a
short trial run.
- Do not start up the pump with a
completely closed shut-off gate valve.
- Never take the pump out of the water
while it is still operating.
- With a three-phase power supply make sure the
direction of rotation is correct.
- The correct direction of rotation will provide a
considerably greater pressure and delivery capacity.
- If it's not correct switch off the power, invert the
connections of two phases on the control panel,
restart and check the pressure or flow rate capacity
again.
- The pump shall operate within its range of
rated performance and the absorbed
current indicated must not be exceeded.
7. MAINTENANCE:
- Under normal operating condictions the pump will
not require maintenance.
- If the pump is temporarily used with dirty liquids or
water containing chloride, flush the pump briefly with
clean water immediatly after use to remove any
deposite.
- If the pump has not been used for a long time and
does not start or gives no water (but electrical
connections are in order), the pump must be removed
from the water and checked to see if it is choked by
any foreign matter or blocked by sediments, deposits
or any other cause.
