2.6 Unauthorised modification and manufacture of spare parts
Modifications to the product/unit are only permissible after consultation with
the manufacturer. Original spare parts and accessories authorised by the man-
ufacturer ensure safety. The use of other parts can nullify the liability from the
results of their usage.
2.7 Improper use
The operating reliability of the supplied product/unit is only guaranteed if the
product/unit is used as intended in accordance with Section 4 of the operating
instructions. The limit values must on no account fall under or exceed those
specified in the catalogue/data sheet.
3 Transport and interim storage
Immediately check the product for any transit damage on arrival. If damage is
detected, the necessary steps involving the forwarding agent must be taken
within the specified period.
CAUTION! Risk of damage!
Inappropriate transport and interim storage can cause damage to the prod-
uct.
The unit must be protected from moisture, frost and mechanical damage
during transport and interim storage.
4Intendeduse
The condensate lifting unit serves as a component in installations for pumping
accumulated condensate. The condensate lifting unit works automatically and
is ready for connection. It is not intended for installation in gas condensing boil-
ers with a condensate pH value of 2.4 or higher.
CAUTION! Risk of damage!
If the condensate lifting unit is being used in gas-fired boilers with an output
of > 200 kW, or in oil-fired boilers in general, a neutralisation unit must be
installed upstream of it.
The condensate lifting unit can also be used in:
• Air-conditioning units, refrigerators and freezers, refrigerated display cases and
evaporators.
The condensate lifting unit is not designed to be used by persons (including
children) with impaired physical, sensory or mental capabilities or who have
insufficient experience or knowledge to operate the unit.
Any such use is considered outside the intended use.

6Descriptionandfunction
6.1 Description
The condensate lifting unit serves as a component in installations for pumping
accumulated condensate. The condensate lifting unit is used when the conden-
sate cannot be disposed of via a natural fall or when the installation site of the
system lies below the backflow level.
The unit is ready for connection and is fitted with a mains plug (1 ~ 230 V) for a
shock-proof socket. The condensate inlet connection and the condensate dis-
charge connection are in thecover of the condensate collection reservoir (Fig. 1,
item 6). A non-return valve is built into the condensate discharge connection
(Fig. 1, item 4).

6.2 Function
The condensate lifting unit is controlled via three switching points.
• If the condensate level in the condensate collection reservoir reaches 43 mm
(Fig. 2, item B), the cut-in level is reached and the pumping sequence begins.
• If the condensate level in the condensate collection reservoir drops to 27 mm
(Fig. 2, item A), the cut-off level is reached and the pumping sequence stops.
• If the condensate level in the condensate collection reservoir reaches 67 mm
(Fig. 2, item C), the alarm level is reached and the alarm switch triggers the
alarm.
The alarm switch is built into the unit, and serves as an overflow protection
measure. It is connected to the unit in which the condensate collects or to the
Wilo-DrainAlarm 2 by the 1 m long alarm cable.
The unit is fitted with a monoblock centrifugal pump. The unit motor has a ther-
mal winding contact (WSK) which switches off at a temperature of 130 °C and
automatically switches on again once the temperature has cooled.
7 Installation and electrical connection
DANGER! Risk of fatal injury!
Incorrect installation and improper electrical connections can be life-threat-
ening.
• The installation and electrical connection must be carried out only by quali-
fied personnel in accordance with applicable regulations.
• Observe the regulations for accident prevention.
• Before installation and electrical connection, disconnect the system from
the power supply and make sure it cannot be switched on by unauthorised
persons.
• Disconnect the mains plug!
7.1 Preparations for installation
• Select an installation location suitable for the size of the unit and accessibility
of the connections.
• Dimensions of the unit (H x W x D): 210 mm x 120 mm x 167 mm
• The condensate lifting unit must be installed in a dry, well-ventilated, frost-free
room.
NOTE! The motor unit of the condensate lifting unit can be placed either clock-
wise or anti-clockwise on the condensate lifting unit, depending on the instal-
lation site.
• Press in the housing clips (Fig. 1, item 3).
• Remove the motor unit.
• If necessary, turn the motor unit, set it in place and press down until the housing
clips click audibly.
