Installation and electrical connection

Installation and electrical connection may only
be performed by qualified personnel in accord-
ance with local regulations.
WARNING! Danger of injury!
Observe the applicable accident prevention
regulations.
WARNING! Danger due to electrical voltage!
Danger from electrical current must be
eliminated.
7.1 Receipt
Unpack the pump and dispose of the packaging
while observing environmental regulations.
7.2 Installation
Install the pump in a dry, well ventilated and
frost-free location on a flat cement surface
and secure it with the screws intended for the
purpose.
CAUTION! Risk of wear and damage to the
pump!
Foreign objects or contaminants in the pump
housing can impair the function of the product.
• It is recommended that all welding or soldering
work is completed before installing the pump.
• Flush the entire circuit before installing and com-
missioning the pump.
- To make inspection or replacement easier, the
pump must be installed in a location which is
easy to access.
- To simplify the dismantling of heavy pumps,
attach a lifting hook vertically above the pump
(Fig. 1, pos. 10).
WARNING! Risk of burns from hot surfaces!
The pump must be set up so that people can-
not come into contact with hot surfaces during
operation.
WARNING! Risk of tipping over!
The pump must be anchored securely to the
ground.
CAUTION! Danger of contaminating the pump!
It is important to ensure that the pump housing
covers are removed before installation.
NOTICE: As all pumps have their hydraulic output
tested at the factory, there may be some residual
water in the pump. For reasons of hygiene, it is
recommended that the pump is flushed each
time before being used for drinking water.
WARNING! Risk of tipping over!
When purchasing the pump, particular attention
should be paid to the fact that, for the larger
versions, a higher centre of gravity poses several
risks during pump operation.
Installation and operating instructions –
Wilo-Multivert MVISE 3G
- The installation surface must be horizontal and
flat. Any slanting of the pump results in prema-
ture wear.
- Place insulating material (cork or reinforced
rubber) under the pump to prevent noise pollu-
tion and the transfer of vibration to the system.
- Only the provided screws may be used for the
installation of the oval flange. Longer screws
can damage the pump housing.
