6.2 Mains refill mode with drinking water:
Check the firm fit of the floating switch and the free mo-
vement of the floating arm in the basic tank. Be very careful
to make sure you do not damage the valve.
Now open the feed to the floating switch. The drinking
water feeding tank fills up with water. The floating switch clo-
ses after a short time. No water may escape via the emer-
gency overflow.
Only if the emergency overflow is connected to the
sewer, overfill the tank by pressing the floating arm down ca-
refully. The water level rises to the edge of the overflow and
flows away through the emergency overflow. Check the
emergency overflow for leaks.
SOnce this setting work has been carried out, the system
is operated for a certain time in feeding mode (see the ope-
rating instructions of the switch unit Aqatronic®) to ventilate
these pipes too. If the system should run dry, proceed as de-
scribed above.
After checking the floating switch again, place the cover
on the basic tank.
Check all the connections for leaks and tighten if neces-
sary.
Close the installation door.
The air vents on the pump housing must not be covered
up. Fresh air circulation must be guaranteed.
Your KESSEL rainwater pumping system
Aqabull
®
is
now ready for operation
6. Initial operation
The chapter "Safety instructions" must be heeded!
The KESSEL rainwater pumping system
Aqabull
®
requires
almost no servicing.
Avoid the pump running dry since the slip ring seal is coo-
led by liquid.
If aggressive media are to be pumped, the pump must
be rinsed after use.
Empty the pump through the emptying plug if there is a
danger of frost.
If the KESSEL rainwater pump system
Aqabull
®
is to be
at a standstill for longer periods, the pump body and auto-
matic pressure switch must be emptied. If the system is not
used at all for a longer period, the pump and the automatic
pressure switch must be cleaned and stored in a cleaned and
well-ventilated place
Floating switch or ultrasonic sensor must be cleaned at
regular intervals.
The inlet and pressure pipes as well as all the connec-
tions must be checked for leaks occasionally and sealed if
necessary.
Fine or coarse filters in the floating suction pipe must be
cleaned at regular intervals.
Check the firm fit of the floating switch and the free mo-
vement of the floating arm in the basic tank. Be very careful
to make sure you do not damage the valve.
Only when the emergency overflow is connected to the
sewer. The odour trap of the emergency overflow dries up
over time. This must be filled at regular intervals to avoid
odour pollution. Overfill the tank by pressing the floating arm
down carefully. The water level rises to the edge of the over-
flow and flows away through the emergency overflow.
To reduce foreign matter entering the feeding tank, the
area around the system must be cleaned at regular intervals.
We recommend that you conclude a servicing contract with
your installation company.
A draft contract is enclosed with this operating manual.
