Shut-off valves

Bond the intake-side pipe (105) and the delivery-side pipe (106) to the
shut-off valve (34) and the main housing (1) (Fig. 7).
5.2.8

Pump shaft

The pump unit should be located in the shaft adjacent to the pool.
Ensure sufficient aeration and ventilation in the installation room and
provide a sufficient ground drain. Please observe the pipe dimensions.
A connection for equipotential bonding has to exist in the pump shaft.
5.2.9

Electrical control unit

The control for the counter swim unit is to be located in a dry room.
Connection of the supply lines and pump is to be carried out in
accordance with the enclosed wiring diagram. The applicable
regulations (VDE) are to be observed. Maximum distance between pool
and control box 10 m!
12/2014 VG 766.2320.050
Higher resistance which results in less flow and a higher risk of
cavitation
Longer priming time (up to 12 min).
ATTENTION! The main housing and the screw connections are
made of ABS. A curing time of at least 12 hrs for the bonding
must be observed!
Keep the suction and pressure lines as short and straight as
possible.
Lay the suction and pressure lines below the water level.
Install valves in both the suction and pressure lines.
Avoid valves which close suddenly.
If the pump is positioned further away, the pipe dimensioning has to
be adapted so that an almost loss-free flow is ensured.
Use elbows instead of angles.
At a distance of between 5 m and 10 m:
