6.1 Location

Observe the following to ensure adequate cooling of the motor
and electronics:
• Position Hydro Multi-E in a way to ensure adequate cooling.
See section 6.2.1 Motor cooling.
• The ambient temperature must not exceed 122 °F (50 °C).
• Keep motor cooling fins and fan blades clean.
The pump system must have a 3-foot (1-meter) 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. See section
6

6.2 Mechanical installation

Arrows on the pump base show the direction of the flow of water
through the pump.
1. The pipes connected to the pump system must be of
adequate size. Fit expansion joints in the inlet and outlet pipes
to avoid resonance. See fig. 4.
• Connect the pipes to the manifolds of the pump 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 the pump system is installed in an apartment complex or the
first consumer on the line is close to the pump system, we
recommend that you fit expansion joints on the inlet and outlet
pipes to prevent vibration being transmitted through the pipes.
See fig. 4.
2. Position the pump system on a level and solid surface, for
example a concrete floor or foundation. If the pump 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.
