3. Installing the product

3.1 Location

The pump is designed for indoor installation.
Always install the pump in an dry environment where it will not be
exposed to drops or splashes, for example water, from
surrounding equipment or structures.
As the pump contains stainless-steel parts, it is important that it is
not installed directly in environments, such as:
Indoor swimming pools where the pump would be exposed to the
ambient environment of the pool.
Locations with direct and continuous exposure to a marine
atmosphere.
In rooms where hydrochloric acid (HCl) can form acidic aerosols
escaping from, for example, open tanks or frequently opened or
vented containers.
The above applications do not disqualify for installation of
MAGNA1. However, it is important that the pump is not installed
directly in these environments.
To ensure adequate cooling of the motor and electronics, observe
the following requirements:
• Position the pump in such a way that sufficient cooling is
ensured.
• The ambient temperature must not exceed 40 °C.

3.3 Insulating shells

Insulating shells limit the heat loss from the pump housing and
pipes. Insulating shells are available for single-head pumps only.
3.3.1 Heating systems
Insulating shells increase the pump dimensions.
Insulating shells for pumps in heating systems are factory-fitted
with the pump. Remove the insulating shells before you install the
pump. See fig. 8.

3.3.2 Cooling systems
Insulating shells for pumps in air-conditioning and cooling
systems, down to -10 °C, are available as accessories and must
be ordered separately. See section
air-conditioning and cooling systems.
3.3.3 Insulating the pump
As an alternative to insulating shells, you can insulate the pump
housing and pipes as illustrated in fig. 9.
Do not insulate the control box or cover the operating
panel.
