Installation and operating instructions Wilo-Drain TS 40
11
• Mains fuse: 16 A, time-lag,
• Pump / installation must be earthed in compliance
with regulations,
• Use a residual current operating device
≤
30 mA,
• Use a disconnecting device to disconnect from
the mains with a contact gap width of min. 3 mm,
• The pump is ready for connection.
Pump with three-phase current motor
(3
~
400V):
• For the three-phase current connection (DM) the
leads of the free cable end are to be assigned as
follows:
4-leaded connection cable: 4 x 1,0
2
The free cable end is to be wired up in the switch
box (see switch box Installation and Operating
Instructions).
8 Starting-up
DANGER! Risk of electric shock!
The pump may not be used for draining swim-
ming-pools / garden ponds or similar places
when there are people in the water.
CAUTION! Risk of damage to the pump
Prior to starting up the pump, the shaft and the
intake pipes should be freed from solid matter
such as rubbish.
8.1 Direction of rotation
(only for three-phase
current motors)
The correct direction of rotation must be tested
before the pump is submerged. he correct direc-
tion of rotation is indicated by a directional arrow
on the top of the motor housing.
• Hold the pump in your hand,
• Briefly switch on the pump. The pump will move in
the opposite direction to the motor.
• If the direction of rotation is incorrect, 2 phases of
the mains connection must be exchanged.
8.2 Adjusting the control level
CAUTION! Risk of damage to the pump!
The mechanical seal must not run dry!
• Dry running reduces the life of motor and
mechanical seal.
• As protection against dry running for the
mechanical seal, the motor is fitted with an oil-
filled separating chamber.
• The water level may not be reduced below the
minimum immersion depth of the pump. The level
control is originally set at the following level: see
figure 2
• Fig. 2a:
operating mode S3: connection and electrical
data
• Fig. 2b:
operating mode S1: connection and electrical
data
• When filling the shaft or lowering the pump into
the pit make sure that the float switches can move
freely.
• Switch on pump.
9 Maintenance
Maintenance and repair work should only be
carried out by qualified personnel!
WARNING! Risk of infection!
In order to avoid any risk of infection, mainte-
nance work should only be carried out using
appropriate protective clothing (protective
gloves).
WARNING! Risk of electric shock!
Potential dangers caused by electrical energy
must be excluded
• The pump must be switched off for all mainte-
nance and repair work and secured against
unauthorised operation.
• In principle, damage to the connecting cable
should only be repaired by a qualified electri-
cian.
• Change oil in the mechanical seal chamber one
times the year.
• Unscrew Oil drain plug with seal (Fig. 1, pos. 21).
• Cant the pump until the oil gets out (use a suitable
collecting basin and dispose the oil correctly).
• Fill in new oil (see connection and electrical data).
• Screw in Oil drain plug with seal.
