Installation and operating instructions Wilo-VeroLine-IP-Z
• Keep the area around the pump unit free of contaminants.
CAUTION! Risk of damaging the pump!
Running dry will destroy the mechanical seal.
• Make sure that the pump does not run dry.
• Open the stop valves on the suction and pressure side of the pump.
• Fill the unit with water.
• If a 3~230/400 V AC mains connection is used, switch it on briefly to
check whether the direction of rotation matches the arrow direction
on the fan cover. If the direction of rotation is incorrect, proceed as
follows:
• Swap 2 phases on the motor terminal board (e.g. L1 for phase L2).
• Check current consumption.
• Adjust the motor protection switch to match the specifications on the
rating plate.
Have maintenance and repair work carried out by qualified skilled
personnel only!
It is recommended to have the pump serviced and checked by Wilo
customer service.
DANGER! Risk of fatal injury!
There is a risk of fatal injury from electric shock when working on
electrical equipment.
• Work on electrical equipment may only be done by electricians
approved by the local electricity supplier.
• Before working on electrical equipment, switch it off and secure it
against being switched on again.
• Any damage to the connection cable of the pump should always be
rectified by a qualified electrician only.
• Never use an object to poke around the motor in the terminal box
and never insert anything into the terminal box!
• Follow the installation and operating instructions for the pump,
level control device and other accessories!
DANGER! Risk of fatal injury!
Contact voltage dangerous to human life!
Work on the terminal box may only be started once 5 minutes have
passed, due to the dangerous residual contact voltage (capacitors).
• Before working on the pump, disconnect the power supply and
wait for 5 minutes.
• Check whether all connections (including potential-free contacts)
are voltage-free.
• Never use an object to poke around the openings on the terminal
box and never insert anything into the terminal box!
DANGER! Risk of fatal injury!
Failure to install safety devices on the motor or terminal box can
cause electrical shock or contact with rotating parts, potentially
resulting in life-threatening injuries.
• Before commissioning and after maintenance work, all safety
devices (such as terminal box covers) that were removed must be
reinstalled.
• The tools used during maintenance work must be removed com-
pletely before the pump is started up.
• Keep a safe distance during commissioning.
• Always wear protective clothing, protective gloves and protective
goggles when working.
