seal. During operation, the standard-equipped twister function ensures continuous tur­bulence in the suction area of the pump, preventing settling sediments from sinking and settling. This ensures a clean pump sump and reduces the build-up of odours.
In the HD version, the motor housing and shaft are made from high-quality stainless steel (1.4404).
Drain TC 40
Submersible sewage pump in single-phase current version with oil-filled motor and built-in thermal overload protection with automatic reactivation. The seal is created on the fluid side with a mechanical seal, and on the motor side with a rotary shaft seal.
4.1.3 Level control
4.1.4 Switchgear
4.2 Operating principle
Level control is carried out using a float switch. In the version without a switchgear, the float switch of the submersible sewage pump is used. The “pump On/Off” switching level is pre-set by the cable length of the attached float switch.
In the version with a switchgear, a separate float switch is installed in the tank. The “pump on” switching point is determined by the length of the float switch’s cable. The switching point for “pump off” is defined by the set follow-up time in the switchgear. Additionally, a further float switch can be installed for a high water alarm.
In the “DS” version, a switchgear is supplied. The switchgear is preconfigured and un­dertakes control of both submersible sewage pumps. The switchgear can also be used to implement a collective fault signal (SSM). For further information on the switchgear, consult the attached installation and operating instructions.
Single-pump system: Wilo-DrainLift Box...
The sewage that arrives is channelled into the collection reservoir via the inlet pipe, where it collects. When the water level reaches the switch-on level, the pump is switched on by the attached float switch and the collected sewage is pumped into the connected pressure pipe. When the switch-off level is reached, the pump is immedi­ately deactivated.
Double-pump system: Wilo-DrainLift Box... D (main/standby pump)
The sewage that arrives is channelled into the collection reservoir via the inlet pipe, where it collects. When the water level reaches the switch-on level, the pump is switched on by the attached float switch and the collected sewage is pumped into the connected pressure pipe. When the switch-off level is reached, the pump is immedi­ately deactivated. If the main pump malfunctions, pumping is performed by the standby pump.
4.3 Operating modes
Double-pump system: Wilo-DrainLift Box... DS (alternating operation)
The sewage that arrives is channelled into the collection reservoir via the inlet pipe, where it collects. When the water level reaches the switch-on level, the pump is switched on by a float switch and the collected sewage is pumped into the connected pressure pipe. When the switch-off level is reached, the pump is deactivated after the set follow-up time. Pump cycling is carried out after every pumping procedure. If one pump malfunctions, the other pump is automatically activated.
For enhanced operational reliability, a further float switch can be installed in the tank. A high water level can be defined using this float switch. When the high water level is
reached: ▪The switchgear emits audible and visual alarm signals. ▪Both pumps undergo forced switch-on. ▪The collective fault signal is activated.
As soon as the water drops below the high water level, the standby pump is switched
off once the follow-up time has elapsed, and the warning message is acknowledged
automatically. The main pump continues to run in the regular pumping cycle.
Operating mode S3: Intermittent periodic duty
This operating mode defines a switching cycle in a combination of periods of operation
and standstill. Specified value (e.g. S325%) relates to the operating time. The switch-
ing cycle has a duration of 10min.
If two values (e.g. S325%/120s) are specified, the first value relates to the operating
time. The second value specifies the max. period of the switching cycle.

ation type. ▪The mounted switchgear (“DS version”) is not overflow-proof. Install the switchgear
sufficiently high. Ensure good operation! ▪To transport the lifting unit, take hold of the inlet connecting piece – never pull the
power supply cable! The unit must be transported by two persons.
The pipework is subjected to different pressures during operation. Pressure surges can
also occur (e.g. when closing the non-return valve) which may be several times higher
than the pump pressure, depending on the operating conditions. These different pres-
sures put a strain on the piping and the pipe adaptors. In order to ensure safe and fault-
less operation, the following parameters must be checked and adapted for the piping
and pipe adaptors and designed according to the requirements: ▪Pressure resistance of pipework and pipe adaptors ▪Tensile strength of the pipe adaptors (= longitudinal force fit connection)
The following points must also be observed:

Checking the position of the pumps
The pumps are mounted and positioned in the factory. The pumps may shift during transport, which would impair proper function of the float switches. For this reason, check that the pumps are in the correct position before installation, and if necessary correct according to the illustrations.
Fig.3: Position of the pumps, without switchgear
Fig.4: Position of the pumps, with switchgear
Check the setting of the level control device
CAUTION Incorrect alignment of the float switches may lead to malfunction!
For proper functioning, the float switches must have sufficient space to float and lie flat on the surface of the water. Therefore, ensure correct alignment of the pumps and floaters!
The level control device is factory-mounted and factory-set. The level control device may shift from its mounting during transport and lead to malfunction of the lifting unit. Therefore, check the fixation and the cable length of the float switches prior to install­ation and adjust if necessary.
▪Single- and double-pump system without switchgear
