4.3 GENERAL MAINTENANCE
•
The swimming pool must be maintained and
serviced in accordance with the manufacturer’s
instructions.
•
The skimmer strainer in the surface skimmer
must be cleaned regularly at short intervals.
•
It is important to ensure that the water level in the
pool never falls below the middle of the skimmer
at least (minimum filling level).
5. TAKING OUT OF OPERATION
•
The swimming pool must be winterized in accord-
ance with the relevant instructions of the pool
manufacturer.
•
The filter system must be winterized if there is a
risk of frost. The following should be observed:
Drain the water from the filter tank through the
drain plug at the bottom of the filter tank.
•
The pipes from and to the swimming pool must
be emptied completely.
•
Switch off the power supply (set to 0), unplug the
earthed plug (Schuko).
•
Remove the quartz sand from the filter tank and
store the entire filter system in a frost-protected
area (e.g. in the basement). Do not push or
transport the filled tank, otherwise there is a risk
of breakage.
6. TROUBLESHOOTING
6.1 PUMP DOES NOT DRAW IN WATER
AUTOMATICALLY OR THE PRIMING
TAKES VERY LONG
1. Check the suction line for leaks, as air is drawn in
if the line is leaking.
2. Check the water level in the pool. If the water
level in the skimmer is too low, the pump also
draws in air. Fill water in (increase water level) up
to the middle of the skimmer port.
3. Check whether the skimmer flap can be moved
easily and does no jam. Otherwise, the pump pri
-
ming will be poor or the water column will always
break down. This can damage the pump.
4. Check whether the strainer basket in the skimmer
is clean, if necessary clean the strainer basket.
5. Check whether the gate valves in the suction and
pressures pipes are open.
6.2 INSUFFICIENT PERFORMANCE OF
CIRCULATION PUMP
1. Filter is dirty; it must be backwashed.
2.
Gate valves in the system are not fully open.
3.
Skimmer basket in skimmer dirty? Cleaning required.
4. Suction line leaking, pump draws air in.
