ENGLISH
the tank through the plug-in seal. The distance from the bot-
tom of the tank must be at least 50 mm.
Fix the diaphragm hand pump to the wall in an easily accessi-
ble position. Connect it to the pushed-in pipe and then connect
the pressure pipe to the diaphragm hand pump. Here, too, the
pressure pipe must be looped over the local backup level.
Additional inlet, DN 50, horizontal
Using a hole saw, open the additional inlet by cutting along the
pre-cut groove. Deburr the edges.
Put the plug-in seal, 58/50, into place.
Push the inlet pipe, with an external diameter of 50 mm, into
the tank through the plug-in seal.
NOTICE! The pipes that connect to the low-level inlets on the
side of the unit must be fitted with a bend, as close to the unit
as possible. The pipe invert of this bend must be at a height
of at least 180 mm above the floor on which the unit is fixed.
Air pockets in the connecting pipe can cause run-off problems
and the water could back-up. To prevent back-ups, the inlet
pipe must be vented at its highest point. The ventilation pipe
can be connected into the tank ventilation.
ELECTRICAL CONNECTION
NOTICE! Only qualified electricians may carry out electrical
works to the pump or the controls.
WARNING!
Before carrying out any works: disconnect the pump and the
controls from the mains and take steps to ensure that they
cannot be emergized again.
NOTICE! Never put the mains plug in water! If water gets into
the plug, this can cause malfunctions and damage.
The standards applicable in each case (e.g. EN), the country-
specific regulations (e.g. VDE in Germany), and the regulations
of the local supply network operator must be observed.
Observe the operating voltage (see the type plate)!
The units have a level controller that switches the pump on and
off depending on the level of the water. An integrated alarm
system beeps if there is a malfunction, even if this is only tem-
porary.
If the pump overheats, the motor cuts out due to the winding
thermostat. After the thermostat has switched off the system,
pull out the mains plug before remedying the fault, since the
device can switch itself on again automatically if the power is
still connected. A direct malfunction message is not generated.
Only connect the pump to electrical sockets that have been
installed properly in a dry room, above the backup level, in ac-
cordance with the regulations, and are fitted with at least a 16
A (delay) fuse.

Switching levels
The switch-on and switch-off points have been factory set for
the standard inlet height for the various units.
Alarm system
Malfunction messages are given both optically as well as
acoustically. The standard mains-dependent alarm system
reports motor faults in the pump. At the same time a built-in
acoustic alarm sounds. This acoustic signal can only be turned
off by remedying the fault or by totally deactivating it.
If an acoustic signal would be inappropriate at the installation
site in question, an alarm signal can be relayed via the poten-
tial-free contact (terminals 40 and 41) on the circuit board (in
the plug in the case of compli 310). The potential-free contact
of the centralised alarm can be loaded with a maximum of 5 A /
250 VAC. The contact opens after the fault has been remedied.
External alarm buzzer (accessory)
In the case of compli 310, a mains-independent alarm device
can be fitted as an accessory. There is a mounting base on the
tank for this purpose.
OPERATION
Test run and functional check
1. Open the maintenance cover of the tank.
2. Open the shut-off valves in the inlet and the pressure pipe.
3. Connect the unit to the power supply and observe the indi-
cation for the rotating field direction.
4. Fill the tank up to the switch-on level.
5. The pump will now switch on and empty the tank. Observe
the pumping process through the maintenance opening.
6. Lift the float of the level controller slowly by hand until it is
above the switch-on point and hold it there until the alarm
is triggered.
7. Then close the maintenance opening with the cover and
seal.
8. Check to ensure that the tank, fittings and pipes are water-
tight, by carrying out several switching runs.
Automatic operation
Automatic operation is the normal operating mode of the unit.
The rocker switch must be set to "Automatic". The integrated
level controller switches the pump on and off depending on the
water level in the tank. A green LED lights up when the pump is
operating (in the case of compli 310 when it is ready for opera-
tion).
NOTICE! If unusually large quantities of wastewater flow into
the unit (e.g. when a pool is drained), partially close the shut-
off valve at the inlet until the unit can operate normally again,
switching on and off, (not pumping continuously, since this
could overheat the pump motor).
Manual operation
Set the rocker switch to "Hand". The pump will now operate
permanently and independently of the wastewater level. The
pumping out operation should therefore be observed through
the maintenance opening.
