pump. The pilot light on the terminal box (Item 6)
must be off. If it is on, the pump rotates in the
wrong direction. Then, change any two phases
wires of the power supply.
– If using switchgear with integral electronic over-
load control, it must be adjusted to the full load
current value of the motor.
– Short- term dry- running does not damage the
pump; prolonged dry- running must, however, be
avoided.
– Further steps on plant commissioning in accor-
dance with the Operating Instructions of the
sand filter plant.
7 Maintenance (Fig. 1)
– If not located in a frost- free location (e.g. open-
air pools), ensure that circulating pumps are
drained during winter together with the filter
plant. This is done by undoing the drain plugs at
the pump (Item 7) with the aid of a suitable tool.
The PVC screws are prone to damage. Drain
plugs to be fastened hand-tight only.
– The lint strainer must be checked and cleaned
from time to time. The O-ring gasket and its seat
must be kept clean (Item 5). The filter basket
must be repositioned such that the groove at the
top ring fits the locating knob in the seating of the
strainer housing (obseve Chapter 6, Commis-
sioning).
– In the case of a pump failure, first switch-off the
motor; the stator housing (Item 1) can then be se-
parated from the pump housing by undoing and
removing the eight (8) holding -down screws
(Item 10). When re-assembling, ensure correct
seating of the two (2) O-ring washers (Item 8).
Screws to be tightened cross- wise. Removal
and re- assembly of the stator housing must only
be done by qualified personnel.
ATTENTION!
In order to maintain warranty claims,
repairs must only be effected by
ASTRAL- authorized service.
