CAUTION! The danger of property damage!
Incorrect transport and incorrect intermediate storage can lead to product damage.

• The pump may only be suspended/carried by the strap provided for transport purposes. The cable should never be used for lifting!
• The pump must be protected against moisture, frost, and mechanical damage when transported and stored.

Intended use

The Drain TM 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,
• and 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.
  TMR pump versions are intended for pumping down to a 2 mm suction level from the floor. This version is recommended for mobile installation and pumping clear water.
  The pumps are usually installed underwater (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 fewer 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 mains 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 may 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! The 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 product also includes following these instructions. Any use over and beyond these is interpreted as incorrect use.

Description and function

6.1 Description of the product (Fig. 1)

The pump can be completely submerged in the fluid.
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 pressure 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 with whirl system (TWISTER-Function)
For wastewater with precipitating and floating particles, the submersible pump has been equipped with a whirl system 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 (automatic 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.

• 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!

7.1 Installation
The pump is designed for stationary or transportable installation.

CAUTION! The danger of property damage!
The 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 a 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.

7.2 Electrical connection
DANGER! Risk of fatal injury!
If the electrical connection is not made properly, there is a risk of fatal injury from electric shock.
Only allow the electrical connection to be made by an electrician approved by the local electricity supplier and in accordance with the local regulations in force.

• The type of mains connection current and voltage must correspond to the details on the name plate,
• 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 x 1,0 mm²

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! The 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 direct the jet of water to be fed into the shaft at the suction strainer of the pump. Entrained air can prevent the operating pump from functioning if the vent slit in the housing is blocked.
• 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. The level “h2 min” must be respected (see Fig. 2).

On version TMR, to reach the maximum low suction level, the float switch must be manually lifted. A small degree of water evacuation (lateral slit between the suction strainer and housing) when level “h2” is reached is normal and necessary to ensure the operational safety of the pump.

• Do not direct the jet of water to be fed into the shaft at the suction strainer of the pump.
  Entrained air can prevent the operating pump from functioning if the vent slit in the housing is blocked.
• The maximum quantity of water feeding into the shaft may not exceed the pump‘s capacity.
  Monitor the sump during commissioning.
• To increase the required capacity (by approx.16% of the delivery head) the whirl system device of the TMW pump can be shut down as follows (fig. 3):
  – Pull the mains plug
  – Remove the pump from the sump,
  – Remove the 4 screws (pos. 2) below the suction basket,
  – Remove the whirling device (pos. 1), rotate by 180° and secure again with the 4 screws,
  – Lower the pump again and start-up.

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 the 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.
The pump should therefore be serviced after approx. 2,000 operating hours by a specialist or Wilo After-sales Service, mainly in order to check the seals.
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
