Install the sluice gate before and after the pump.
This prevents the fluid from being drained and refilled
when the pump is exchanged.
4.5 Minimum pressure
The minimum pressure in the pump connection at 75 °C
to ensure lubrication of the friction bearings:
The values apply up to 500 m above sea level.
Additions for higher altitudes:
0.01 bar per 100 m of altitude

5. Electrical connection
The electrical connection must be provided
by a technician in coordination
with the local utility company.
Observe the NIN (CENELEC) regulations.
At higher water temperatures (above 80 °C), use appropriate
heatproof connecting lines.
The connecting line must not touch the tubing, the pump housing,
or the motor housing.
Mind the protection from dripping water and strain relief
when laying cables in the junction box (gland seal).
Back-up fuse:
Wire cross-section:
The electrical connection must be made in accordance
with the data plate.
The electrical connection must be looped to facilitate exchanges
later. Make sure that the electric data on the pump's type plate
correspond with the indicated power supply.
Note: Pay special attention to the protective conductor.
The protective conductor must be longer than the pole conductor
(danger of rupture).
