Dismounting of the lock-ring:
It is not necessary to unscrew the gland housing (161) from the motor (800).
Lever the lock ring by using a large screw driver (e.g. size 10) pressing it
against the outside wall of the lock ring.
Assembly:
Mounting of the new lock ring:
Slightly moisten the sleeve of the complete lock ring with soap water and press
it in evenly with both thumbs.
Also slightly moisten the impeller hub with soap water and press the mechani-
cal seal (433) on to the impeller hub regularly with both thumbs.
In case the gland housing has been disassembled from the motor, take care
not to fasten the plastic screws (910) too tight (tightening moment 1 Nm, "hand-
tight").
Re-assembly of the impeller:
Before re-assembly of the impeller, clean the surface of the lock ring and of the
mechanical seal with alcohol or with a clean paper tissue.
Assembly is effected in reverse order, see Dismantling.
Re-assembly of the motor unit into the pump casing:
First turn the 8 tapping screws (900) to the left until reaching the cut thread by
latching, tighten only afterwards. Please make sure that the screws are not tigh-
tened too strong (tightening moment 5 Nm).
Do not use force!

CAUTION
If there is danger of freezing, the pump must be drained ahead of time. For this
purpose open the closing cap (582) in order to drain off all liquid. Also drain all
pipes subject to freezing.

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 (433) by a new one (see 7.5).
In case of malfunction we recommend contacting the pool builder 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.
