Commissioning
Installation and operating instructions • Wilo-VeroLine-IPL-Z, Wilo-VeroTwin-DPL-Z • Ed.01/2024-07
We recommend an anti-condensation heater for motors which, due to climatic conditions,
are at risk of condensation. These are, for example, idle motors in humid environments or
motors that are exposed to large temperature fluctuations. Motors equipped with an anti-
condensation heater at the factory can be ordered as special versions. The anti-condensa-
tion heater is used to protect the motor windings against condensation water inside the
motor.
•
The anti-condensation heater is connected to the terminals HE/HE in the terminal box
(connection voltage: 1~230 V/50 Hz).
CAUTION
Risk of damage due to incorrect handling!
The anti-condensation heater may not be switched on during motor op-
eration.
•
Electrical work: a qualified electrician must carry out the electrical work.
•
Installation/dismantling: The technician must be trained in the use of the necessary
tools and fixation materials.
•
The product must be operated by persons who have been instructed on how the com-
plete system functions.
DANGER
Danger of death due to lack of protective devices!
Due to missing protective devices of the terminal box or in the range of
the coupling/motor, electric shock or contact with rotating parts can lead
to life-threatening injuries.
• Before commissioning, safety devices such as terminal box covers or
coupling covers that were removed must be reinstalled!
• An authorised technician must check the functionality of the safety
devices on the pump and motor prior to commissioning!
DANGER
Danger of death due to ejected tools!
The tools used during maintenance work on the motor shaft can be
thrown away if they come into contact with rotating parts. Injuries and
even death are possible!
• The tools used during maintenance work must be removed com-
pletely before the pump is started up!
WARNING
Danger of injury due to fluid shooting out and components
coming loose!
Not installing the pump/system correctly can lead to serious injuries dur-
ing commissioning!
• Carry out all work carefully!
• Keep a safe distance during commissioning!
• Always wear protective clothing, safety gloves and safety glasses
when working.
The area around the pump unit must be kept free of contaminants.
In order to eliminate the chance of a fire or an explosion, avoid contaminants coming into
contact with hot unit surfaces.
