Attaching a Rope to Suspend the Pump
Refer to the illustration on the right in order to suspend
the pump by a rope.
CAUTION
Make sure that the rope does not
become twisted during installation.
Failure to observe this precaution
could cause the rope to break, the
pump to fall and break, which could
lead to injury.
CAUTION
With automatic control, the water in the pipe could flow backwards, causing
the water surface control device to react immediately. As a result, the pump
will operate ON/OFF repeatedly, which could cause the pump to malfunction.
(8) Install a check valve if the pump tank is deep, or the vertical head or the lateral distance
is long.
Electrical Wiring Work
WARNING
• All electrical work must be performed by an authorized electrician, in
compliance with the local electrical equipment standards and internal
wiring codes. Never allow an unauthorized person to perform electrical
work because it is not only against the law, but it can also be extremely
dangerous.
• Improper wiring can lead to current leakage, electrical shock, or fire.
• Absolutely provide a dedicated earth leakage circut breaker and a thermal
overload relay suitable for the pump (available on the market). Failure
to follow this warning can cause electrical shock or explosion when the
product fails or an electrical leakage occurs.
Make sure that the power supply and wiring have adequate capacity.
Grounding
WARNING
Make sure to install the ground wire securely. Failure to observe this
precaution could damage the pump and cause current leakage, which may
lead to electrical shock.
CAUTION
Do not connect the ground wire to a gas pipe, water pipe, lightning rod, or
telephone ground wire. Improper grounding could cause electrical shock.
CAUTION
Do not operate the pump with the cabtyre cable dangling. Failure to observe
this precaution may cause the cabtyre cable to become wrapped around the
impeller, which could cut the cable, break the impeller, or cause flooding,
which may lead to current leakage or electrical shock.
(5) Install the submersible pump upright on top of a surface such as concrete, in an area
that is free of turbulence and does not cause the pump to take air in.
(6) The area near the inlet of a water tank is susceptible to turbulence or allows the pump
to take air in; therefore, place the pump and the float switch away from the inlet or
install a baffle plate.
(7) Carry out piping work properly so as not to create any air pockets in the middle of
piping.
