Installation and operating instructions • Wilo-VeroLine-IPL-Z, Wilo-VeroTwin-DPL-Z • Ed.01/2024-07
WARNING
Personal injury and property damage due to improper handling!
Transport lugs mounted on the motor housing can tear out if the load is
too heavy. This can lead to serious injuries and damage to the product!
• Only lift the pump with approved lifting gear (e.g. block and tackle,
crane). See also chapter "Transport and storage".
• Transport lugs mounted on the motor housing are only permitted for
transporting the motor!
Transport lugs are not always found on the motor. See the "Transport and storage" section.
NOTICE
Simplify subsequent work on the unit!
• To ensure the entire unit does not have to be emptied, install shut-off
valves upstream and downstream of the pump.
If need be, the necessary non-return valves are to be provided.
Condensate drainage
•
When using the pump in air conditioning or cooling systems:
The condensate that forms in the lantern can be drained specifically via an existing drilled
hole. A drain pipe can also be connected to this opening and a small amount of escaping
liquid can be drained off.
•
Installation position:
All installation positions except for "motor facing down" are allowed.
•
The air vent valve (Fig. I, Item 9) must always face upwards.
IPL-Z/DPL-Z
Fig. 10: IPL-Z/DPL-Z
Suction and pressure flange are marked with the direction of flow by means of a cast arrow.
The direction of flow must correspond to the directional arrow on the flange.
NOTICE
The motor terminal box must not face downward. If necessary, the motor
impeller unit can be rotated once the interior hexagonal head screws have
been loosened. While rotating the motor or motor impeller unit, ensure
that the housing O-ring seal is not damaged.
NOTICE
When pumping from an open tank (e.g. cooling tower), ensure that there is
always a sufficient liquid level above the pump's suction port. This pre-
vents the pump from running dry. The minimum inlet pressure must be
observed.
NOTICE
In the case of insulated systems, only the pump housing may be insulated.
Never insulate the lantern and motor.
