shall not be placed a manner that would pose a risk of tripping. The power supply socket should be located in a place where it is
always possible to quickly remove the appliance power cord plug. Always pull the power cord by the plug housing when unplug-
ging it, never by the cord.
If the power cord or the plug are damaged, immediately disconnect it from the power supply and contact an authorised service
centre of the manufacturer for replacement. Do not use the appliance with a damaged power cord or plug. The power cord or plug
cannot be repaired and must be replaced with a new one that is free of defects if these components are damaged.
DEVICE OPERATION
Connecting the outlet hose
The water outlet is equipped with a thread to which a hose connector must be connected. You can use the connectors provided
with the pump or available separately. If a hose with the inside diameter smaller than the water outlet diameter is used, the pump
capacity will decrease. The connector included in the pump equipment has the possibility to connect hoses of diff erent diameters.
When connecting a hose with a diameter larger than the smallest diameter of the connector, cut off the smaller diameter part of
the connection so as not to restrict the fl ow of the pump. The connector is made of plastic, so the cut can be made with a sharp
knife. Be careful when cutting to avoid injury.
The hose connector must be screwed on without tools with suffi cient force to ensure a tight connection. Use of excessive force
can damage the gasket.
Starting and stopping the pump
The pump does not have a standard on/off switch. It is activated and stopped, depending on the model, by a fl oat on/off switch
or an adjustable on/off switch.
The fl oat on/off switch is connected to the pump by means of a short electric cord and contains a moving element inside which
closes and opens the electrical circuit. The switch fl oat is raised in the water, which causes the electrical circuit to close and the
pump to start. If the water drops to such a level that the fl oat of the switch is directed upwards by the cable connector, the pump
will be switched off .
The fl oat switch can be attached to the pump housing by means of the clip (II). In this position, the switch will start the pump every
time it is connected to the power supply, regardless of the water level. This method of fi xing should be used with caution as dry
running of the pump will lead to overheating and, as a consequence, damage to the pump. It is recommended to use this method
only during the transport of the pump, so that the switch does not strain the cord with which it is connected to the pump.
Placing the cord connecting the fl oat switch with the pump in the handle on top of the pump housing (III) "shortens" the loose part
of the cord. This can be used to change the height of the water level, which will cause the pump to switch on and off . Leave the
cords between the handle and the switch long enough to allow the switch to change position freely. Too short a distance will not
allow the pump to be switched on or off .
The adjustable switch has a slider which sets the water level at which the pump will start. If the water level is at the height of the
central part of the slider (IV), the pump will start operating. The pump will be switched off when the water level drops below the
lowest possible slider setting, even if the slider is in a higher position. Approximate water level at which the pump will be switched
off by the adjustable switch is specifi ed in the table with technical data - parameter: "Switch-off level".
Pump base replacement (only for YT-85330 and YT-85333) (V)
Warning! Make sure the pump is disconnected from the power supply before replacing the base. The power cord must be un-
plugged from the socket.
The pump base can be replaced, depending on the purity of the pumped water. The base with small openings is used to pump
clean water, while the base with large openings is used to pump contaminated water. As the base for pumping contaminated water
is higher, there will also be a higher water level after the pump has fi nished its operation. To replace the base, unscrew the base
fi xing screw, then carefully swivel the cover latch and remove the cover. Mount the cover by snapping it onto the pump housing
and screwing it in place. Caution! It is forbidden to use the pump without the base fi xed.
MAINTENANCE, TRANSPORT AND STORAGE
When the pump has fi nished working, disconnect it from the power supply and take it out of the water. Disconnect the hose
from the pump outlet and allow the water to fl ow out of the pump under gravity. During this operation, the pump must be tilted in
diff erent directions. After emptying the pump, dry it externally with a soft cloth or leave it to dry. If water with impurities has been
pumped, pump clean water until the dirt water ceases to escape from the pump. The external parts of the pump may be cleaned
by means of a clean water jet with a pressure of not more than 0.3 MPa. When cleaning the pump, be careful not to get the plug
of the power cord wet.
Transport the pump emptied and dried. Move by grasping the handle on top of the housing or by the housing. Never transport the
pump by pulling or hanging it by the power cord or the cord connecting the fl oat switch to the pump. Transport in packaging which
protects the pump from dust and dirt.
Store the pump emptied and dried. The water left in the pump can freeze and cause damage to the pump. Store the pump in
shaded areas which provide good ventilation and are protected against unauthorised use, especially by children.
