Figure 4.5 STP Pump Installation Positions
When installing the STP pump in a horizontal or slanted position, it is recommended to
install the pump so that the direction of the outlet port is on a vertical or horizontal plane
in the direction of the gravity to reduce the load on the magnetic bearing and the heat
generated by the STP pump. In addition, in order to enhance the effect of radiating fin,
install the pump in accordance with the order of precedence shown below:
1. The direction of the outlet port is on a vertical plane in the direction of the gravity
(see Figure 4.6 (a-i)).
2. The direction of the outlet port is on a horizontal plane in the direction of the gravity
and the control unit is in the upper position (see Figure 4.6 (b-ii)).
3. The direction of the outlet port is on a horizontal plane in the direction of the gravity
and the control unit is in the lower position (see Figure 4.6 (b-iii)).

Installation of the STP-iXL455 series
It is recommended to mount the STP-iXL455 series in the vertical position.
The STP pump may be inclined by its own weight in other positions in the case of
atmospheric release. To protect a structure for reduce vibration level, install
prevention measures for the inclination of the pump.
