Intended use

The Drain-TS series drainage and submersible wastewater pumps are used:

•  for the automatic drainage of pits and shafts,
•  for keeping dry yard areas and basement rooms exposed to flooding,
•  for lowering surface water, if the waste water is not able to flow off into the sewer system through natural fall. The pumps are suitable for pumping slightly contaminated water, rainwater, drainage water and washing water. The pumps are usually installed under water (submerged) and can only be permanently or transportable installed vertically. Because of the sheath current cooling, the pumps can also be operated unsubmerged. Submersible pumps with a mains connection cable of less than 10 meters are (according to EN 60335) only permitted for use inside buildings, i. e. not for operating outside. Pumps that are intended for use in or at garden ponds or similar places must have a main connecting cable that is not lighter than rubber sheathed cables reference H07 RN-F (245 IEC 66) according to EN 60335.

DANGER! Mortal danger due to electric shock! The pump many not be used to drain swimming pools/garden ponds or similar places if anyone is in the water.

WARNING! Hazardous to health!
Owing to the materials used, the pumps are not suitable for potable water! Unpurified foul and wastewater represent a health hazard.

CAUTION! Danger of property damage! Pumping unpermitted substances can lead to product damage.
The pumps are not suitable for water with coarse contamination such as sand, fibers or combustible, caustic fluids or for use in potentially explosive areas.
Correct use of the pump/unit also includes following these instructions. Any use over and beyond these is interpreted as incorrect use.

Description and function

Description of the product (Fig. 1)

The pump can be completely submerged in the fluid. The submersible pump housing consists of stainless steel. The electric motor is protected against the pump chamber by a rotary shaft seal to seal the motor against the oil chamber and a mechanical seal to seal the oil chamber against the fluid. The mechanical seal chamber is filled with medical white oil so that the mechanical seal is lubricated and cooled during a dry run. A further rotary shaft seal protects the mechanical seal facing the fluid. The motor is cooled by the surrounding fluid. The pump is installed on the floor of a shaft. For a stationary installation, it is bolted to a fixed pres-sure pipe or for a transportable installation, it is connected to a hose connection. The pumps are commissioned by plugging in the protective contact plug.   They operate automatically when the float switch switches the pump on from a certain water level “h” (Fig. 2) and switches it off at a minimum water level “h1”. The motors are equipped with thermal motor protection, which switches off the motor automatically if it overheats and switches it on again when it has cooled down. The condenser is integrated in the single-phase motor.

Version TSW with turbulator
For wastewater with precipitating and floating particles, the submersible pump has been equipped with a turbulator at the suction strainer. Precipitating particles are continuously whirled up in the suction area of the pump and pumped off with the water. Therefore, mud accumulation in the pump shaft, with problematic consequences such as clogging of the pump and odor formation, is largely prevented. If the removal of the waste water does not allow any interruption, a second pump (automat-ic standby pump), together with the necessary switchgear (accessory), increases the operating reliability if the 1st pump develops a fault.

Installation and electrical connection

DANGER! Risk of fatal injury!
Incorrect installation and improper electrical connections can result in a risk of fatal injury.

• The installation and electrical connections should only be done by properly skilled staff and in compliance with the applicable regulations!
• Follow all accident prevention regulations!

Installation

The pump is designed for stationary or transportable installation.
CAUTION! Danger of property damage!Danger of damage due to incorrect handling. Only suspend the pump by the strap with the aid or a chain or rope, never by the electrical or float switch cable or the pipe/hose connection.

•  The installation site or shaft for the pump must be free of frost.
•  The shaft must be cleared of coarse material such as rubble before setting up and starting the pump.
•  The quality of the shaft must guarantee the unhindered mobility of the float switch.
•  Installation dimension / shaft dimensions (cf. Fig 2).

The diameter of the pressure pipe (pipe/hose connection) should not be smaller than the pressure connection of the pipe because of the increased risk of clogging and greater pressure losses. To avoid pressure losses, it is recommended that the pipe connection one number higher is selected.

Stationary wet-sump installation

In the case of a stationary wet-sump installation of the pump with a permanent pressure pipe, the pump must be positioned and secured so that:

•  The pressure pipe connection does not support the weight of the pump.
•  The load of the pressure pipe does not act on the connecting socket.
•  The pump is installed stress-free.
• To protect against any backflow from the public drainage pipe, the pressure pipe must be taken in an arc over the locally established backflow level (usually street level). A non-return valve does not represent a guaranteed backflow seal.
•  The attached non-return valve should be installed if the pump is installed permanently.
•  Seal the pipe connections to the pressure port with Teflon tape.
  NOTE:
  Permanent leakage in this area can lead to the destruction of the non-return valve and of the screwed connection.

Transportable wet-sump installation

In the case of a transportable wet-sump installation with hose connection, the pump must be secured in the shaft to prevent it from falling over and wandering (e.g. secure chain/rope with slight pre-tension).
NOTE:
When used in a sump without a firm base, the pump must be put on a sufficiently large plate or hung from a rope or a chain in a suitable position.

Electrical connection

•  The type of mains connection current and voltage must correspond to the details on the nameplate
•  Fuse in the power supply: 10 A, slow,
•  Earth the installation according to the regulations.
•  The installation of a leakage current protection switch to be provided on-site for a trip current of 30 mA is recommended (caution when installing outside).
•  The pump is ready to connect.

To connect the pump to the switchgear, the shock-proof plug is disconnected and the connecting cable is then connected as follows (see Installation and operating instructions for the switchgear):
3- wire connection cable: 3×1,0 mm².
Brown: L1
Blue: N
green/yellow: PE
Socket and switchgear must be installed in a dry room and protected against flooding.

Commissioning

DANGER! Danger through electric shock! The pump may not be used to drain swimming pools/garden ponds or similar places if anyone is in the water.

CAUTION! Danger of property damage! Do not allow the mechanical seal to run dry!Dry running shortens the service life of the motor and the mechanical seal. If the mechanical seal is damaged, small amounts of oil may escape into the pumped fluid.

•  When filling the shaft or lowering the pump into the pit, make sure that the float switches can move freely. The switch must switch off the pump before the intake openings of the pump can draw in air.
•  After filling the shaft and opening the check valve on the pressure side (if provided), the pump starts up automatically when the switch-on level ‚h‘ is reached and switches off as soon as the switch-off level ‚h1‘ responds.
•  Do not point the water jet entering the shaft at the pump strainer. Entrained air can prevent the pumping of the pump when it is starting up.
•  The maximum volume of water entering the shaft must not exceed the performance of the pump. Keep an eye on the shaft when commissioning the pump.

NOTE: The venting of the pump when commissioned for the first time will be improved by submersion in the fluid at an angle or by positioning it at a slight angle.

Adjusting the switching level of the float switch
The perfect functioning of the level control system is guaranteed if the details according to the table in 7.1 and Fig. 2 are observed. The switching level (switch-on/off point) can be changed via the free float switch cable by moving the cable within the clip on the pump handle.

NOTE: In order not to damage the float switch cable when adjusting the level, the clip has to be released. If necessary, by pegging the float switch in a higher position, a drainage level of up to approximately 8 mm (TSW: 18 mm) can be achieved.

To do this, release the float switch clip on the pump handle. Raise the float switch in relation to the handle and, working in the opposite direction, fix the cable, as close to the switch as possible, on the handle again with the aid of the clip. The automatic system is then switched off and the pump runs continuously. An automatic operation can also be achieved with the aid of switchgear from the accessories range.

Maintenance

Maintenance and repairs may only be carried out by qualified experts!
DANGER! Risk of fatal injury!
There is a mortal danger through shock when working on electrical equipment.

•  Before any maintenance and repair work, the pump must be switched off and prevented from being switched on again in an unauthorized manner.
•  Damage to the connecting cable may only be repaired by a qualified electrical contractor in principle.
•  When checking the function following long downtimes, avoid contact with the fluid.

In order to prevent blockage of the pump resulting from long downtimes, its ability to function should be checked at regular intervals (every 2 months) by manual raising of the float switch or direct switching-on and brief start-up of the pump. Minor wear of the rotary shaft seal and mechanical seal can lead to fouling of the liquid following an oil leak from the oil chamber, which is filled with medical white oil. Only specialist companies or Wilo After-sales Service may open the encapsulated motor.

Cleaning the pump

Depending on the use of the pump, fouling can occur within the suction strainer and the impeller. Rinse off the pump under running water after use.

1.  Switch off the power supply. Disconnect the mains plug.
2.  Drain the pump
3.  The suction strainer is bolted to the pump housing. Undo the 2 screws on the suction strainer with a suitable screwdriver and remove the suction strainer.
4.  Clean the suction strainer under running water.
5.  Undo the 4 screws on the bottom part of the pump housing and remove the housing. Handle the O-ring between the pump housing and motor housing carefully.
6.  Clean the impeller and pump housing under running water. The impeller must turn freely.
7.  Replace damaged or worn parts with original spares.
8.  Re-assembly the pump in the reverse order.
