2.5 Safety instructions for inspection and installation work
The operator must ensure that all inspection and installation
work is carried out by authorised and qualified personnel, who
are sufficiently informed from their own detailed study of the
operating instructions.
Work on the product/unit should only be carried out when it has
been brought to a standstill. It is mandatory that the procedure
described in the installation and operating instructions for
shutting down the product/unit be complied with.
2.6 Unauthorised modification and manufacture of spare parts
Modifications to the pump/system are only permitted after
consultation with the manufacturer. Original spare parts and
accessories authorised by the manufacturer ensure safety. The
use of other parts can nullify the liability from the results of
their usage.
2.7 Improper use
The operating safety of the supplied product is only guaranteed
for conventional use in accordance with Section 4 of the oper-
ating 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 found, the necessary procedure involving
the forwarding agent must be taken within the specified period.
CAUTION! Risk of damage to the pump!
Danger of damage due to incorrect handling during transport
and storage.

English
7WILO SE 05/2011
• The pump should be protected from moisture, frost and
mechanical damage due to impact during transport and
interim storage.
• The device must not be exposed to temperatures outside the
range of -10 °C to +60 °C.
4 Intended use
The circulation pumps in the E.../1-5 series are designed for
warm water heating systems and similar systems with con-
stantly changing volume flows. Approved fluids are heating
water in accordance with VDI 2035, water/glycol mixture at a
mixing ratio of max. 30 % of glycol. If glycol is added, the deliv-
ery data of the pump must be corrected according to the higher
viscosity, depending on the percentage mixing ratio.

7.1 Installation
• Only install the pump after all welding and soldering work has
been completed and, if necessary, the pipe system has been
flushed through.
• Mount the pump in a readily accessible place for easy inspection
and dismantling.
• When installing in the supply leg of open systems, the safety
supply must branch off upstream of the pump (DIN EN 12828).
• Install check valves upstream and downstream of the pump to
facilitate a possible pump replacement.
• Perform installation so that any leaking water cannot drip
onto the control module.
• To do this, align the upper gate valve laterally.
• In thermal insulation work, make sure that the pump motor and
the module are not insulated. The condensate drain openings
must remain uncovered.
• Install without tension and with the pump motor in the hori-
zontal position. See fig. 3 for installation positions of the pump.
• Direction arrows on the pump housing indicate the direction of
flow.
• If the installation position of the module is changed, the motor
housing has to be turned as follows:
• Loosen the internal hexagon screws,
• Turn the motor housing, including control module.
CAUTION! Risk of damage to the pump!
The gasket may be damaged when the motor housing is
turned. Replace defective gaskets immediately.
• Twist the internal hexagon screws back in and tighten them,

7.2 Electrical connection
DANGER! Danger of electric shock!
Electrical connection must be carried out by an electrician
authorised by the local electricity supply company and in
accordance with the applicable local regulations [e.g. VDE
regulations].
7.2.1 Electrical connection with Wilo-OEM-Connector
The pump is delivered with the specific Wilo-OEM-Connector
assembled on the electronic module (fig. 4-b):
1 = L1, 1~230 V / 50 Hz
2 = N, neutral conductor
3 = Earth conductor
The mating plug to the OEM plug can be ordered with one of the
following suppliers. (Wilo does not assume any liability for the
products supplied by these manufacturers):
• LTE (www.lte.it)
• FACON (www.facon.it)
7.2.2 Electrical connection with cable
The pump is delivered with a cable assembled on the pump.
The free ends of the cable must be connected in the system
switchbox.
• black/brown wire: L1 (phase)
• blue wire: N (neutral conductor)
• green/yellow wire: PE (earthing)
8 Commissioning
WARNING! Risk of burns!
Depending on the pump/system operating conditions (fluid
temperature), the entire pump/system can become very hot.
Touching the pump can cause burns.

English

8.1 Filling and air venting
Fill and vent the system correctly. The pump rotor chamber
normally vents automatically after a short time in operation.
However, if direct venting of the rotor chamber is required, the
air venting routine can be started.
To do this, turn the red button (fig. 4-a) to select the symbol for
air venting. The duration of the bleeding routine is 10 minutes.
Noises may be heard during the air venting routine. The process
can be stopped if desired by turning red button. At the end of
the process, the pump switches automatically to a pre-set
speed. After that, the desired control mode can be set at the red
button.
8.2 Setting the control mode (fig. 2a, 2b) and delivery head
Turn the red button (fig. 4-a) to select the control mode symbol
and adjust the desired delivery height between 1 m and 5 m.
Variable differential pressure (Δp-v): fig. 2a
The differential pressure setpoint is increased linearly over the
permitted volume flow range between ½H and H. The differen-
tial pressure generated by the pump is adjusted to the corre-
sponding differential pressure setpoint. This control mode is
especially useful in heating systems with radiators, since the
flow noises at the thermostatic valves are reduced.
Factory setting Δp-v, 5 m
Constant differential pressure (Δp-c): fig. 2b
The differential pressure setpoint is kept constant over the per-
mitted volume flow range at the set differential pressure set-
point up to the maximum pump curve. Wilo recommends this
control mode for underfloor heating circuits or older heating
systems with large-sized pipes.

9 Maintenance
Only allow qualified specialist staff to perform maintenance
and repair work.
DANGER! Danger of electric shock!
Any danger from electrical current should be ruled out.
• The pump should be electrically isolated and secured against
unauthorised switch-on during any maintenance or repair
work.
• Any damage to the connection cable should always be recti-
fied by a qualified electrician only.
