If there is danger of freezing, the pump must be drained ahead of time. For this
purpose open the drain plug (903) in order to drain off all liquid. Also drain all
pipes subject to freezing.
When operating with natural sea water (salt water) it is necessary to rinse the
pump with plain tap water before closing it for a longer period (e.g. end of sea-
son), otherwise there might be danger of formation of crystals at the surfaces of
the mechanical seals (433).
7.5
The leakage outlet on the underside between pump housing and motor must
never be clogged or sealed; otherwise the water in it will rise and the motor will
be damaged! Please make sure that leakage cannot cause consequential da-
mages! If necessary provide a suitable drip pan.
8. In Case of Malfunction
The sealing between the motor and the pump housing is done by means of a
mechanical seal (433). It is normal that a few drops of water seep through once
in a while, especially during the break-in period. Depending on the nature of the
water and the duration of operation said mechanical seal may become leaky
after some time. If the water penetrates continuously, replace the complete me-
chanical seal by a new one (433), see 7.3.
In case of malfunction we recommend contacting the pool builder or the
supplier of the unit first.
If ball bearings must be replaced, bearings with C3 air and high-temperature
grease (approx. 180°C) are to be used!
When restarting the pump, refer to item 6.
