4. Installing the product
WARNING
Crushing
Death or serious personal injury
‐ Use professional installation tools when moving or
lifting the system or the components.
‐ Use safety equipment when mounting the base frame.
‐ Use the supplied wooden beams delivered to support
the system when mounting the vibration dampers.
‐ Installation must be carried out by trained personnel.
CAUTION
Overhead load
Minor or moderate personal injury
‐ Use appropriate lifting equipment when placing the
system.
CAUTION
Crushing of feet
Minor or moderate personal injury
‐ Use safety equipment when installing the pipes.
‐ Use safety equipment when installing the tank.
CAUTION
Sharp element
Minor or moderate personal injury
‐ Wear safety gloves.
4.1 Location
Observe the following to ensure adequate cooling of motor and
electronics:
• Position Hydro Multi-E in such a way that adequate cooling is
ensured. See section Ensuring motor cooling.
• The ambient temperature must not exceed 40 °C.
• Keep motor cooling fins and fan blades clean.
The system must have a 1-metre clearance in front and on the two
sides.
For outdoor installation, always place the system under a
roof to avoid exposing the system to direct sunlight.

Arrows on the pump base show the direction of the flow of water
through the pump.
1. The pipes connected to the system must be of adequate size.
Fit expansion joints in the inlet and outlet pipes to avoid
resonance.
• Connect the pipes to the manifolds of the system.
The manifold comes with a screw cap fitted to one end. If this
end is to be used, remove the screw cap, apply sealing
compound to the other end of the manifold, and fit the screw.
Fit a blanking flange with gasket on flanged manifolds.
• Fasten all screws and bolts before starting the pump.
• If systems are installed in blocks of flats or the first consumer
on the line is close to the system, we recommend that you fit
expansion joints on the inlet and outlet pipes to prevent
vibration being transmitted through the pipes.
2. Position the system on a plane and solid surface, for example a
concrete floor or foundation. If the system is not fitted with
vibration dampers, it must be bolted to the floor or the
foundation.
3. Fasten the pipes to parts of the building to ensure that they
cannot move or be twisted.

4.2.1 Ensuring motor cooling
Leave at least 50 mm between the end of the fan cover and a wall
or other fixed objects.

4.3 Drain holes
When the motor is installed in moist surroundings or areas with high
humidity, the bottom drain hole must be open. If the humidity is
constantly high and above 85 %, open the drain holes in the drive-
end flange. The enclosure class of the motor will then be lower. This
helps prevent condensation in the motor as the motor becomes
self-venting, and it allows water and humid air to escape.
The motor has a plugged drain hole on the drive side. You can turn
the flange 90° to both sides or 180°.
