in possession of the respective qualifications
required for this work.
2.3 Danger in the event of nonobservance of the
safety instructions
The failure to observe the safety instructions
could result in dangers to personnel and
pump/installation. Nonobservance of the safety
instructions can result in the loss of any claims to
damages.
In particular, the failure to observe these instruc-
tions could lead to the following hazards:
• Failure of important functions of the pump/instal-
lation.
• Hazards to personnel resulting from electrical,
mechanical or bacteriological actions,
• Property damage.
2.4 Safety instructions for the operator

technik e.V.) and of the local energy supply com-
panies are to be complied with.
2.5 Safety instructions for inspection and installa-
tion work
It is the responsibility of the operator to ensure
that all inspection and installation work is carried
out by authorised and qualified professionals who
have acquired sufficient information from a
detailed study of the Installation and operating
instructions.
As a fundamental principle, work may only be car-
ried out on the pump/installation when it/they are
at a standstill.
2.6 Customer's own conversions and spare parts
manufacture
Modifications to the pump/installation are not
permitted except after consultation with the
manufacturer. The use of original spare parts and
manufacturer-authorised accessories promotes

cancellation of liability for the results of such
substitutions.
2.7 Improper use
The operating safety of the supplied pump/instal-
lation is only guaranteed for conventional use in
accordance with Section 1 of the Installation and
operating instructions. It is not permitted to
exceed or fail to meet the limit values specified
in the catalogue/data sheet under any circum-
stances.
3 Transport, handling and storage
The pump/installation is to be checked at once
upon delivery for any damage that may have
occurred in transit. If any damages are found, then
they are to be reported to the transport company
immediately within the time periods specified.
If the material is to be installed later,
then it must be stored in a dry location.
The material must be protected against
impact shocks and all external influ-
ences (moisture, frost, etc.).

5 Installation
Two types:
•see Fig 1: Suction mode.
•see Fig. 2: Pressure operation from replenish-
ment vessel (Pos. 9) or potable water network
(Pos. 10).
5.1 Installation
Install the pump at a readily accessible location
which is protected against external influences
(excessive rain or sunlight, frost) and which is as
near as possible to the extraction point.
Place the pump on a pedestal (Pos. 13) or directly
on a smooth, level base. Fixation of the pump
with 2 holes for Ø M8 bolts.
Note that the height of the installation
location and the temperature of the
fluid will diminish the suction capacity
of the pump.
Installation should be carried out in
pressure operation when temperatures
exceed 80°C.
5.2 Pipe connections
The installation must be sufficient for
the pressure that the pump generates
at maximum frequency and zero flow
volume.
- Connection with spiral-reinforced flexible hoses
or rigid pipe.
-Seal the pipe connections well with suitable
products. No air is permitted to enter the suc-
tion line; lay the suction line with a continuous
rise (2%) (see Fig. 1).
- In the case of rigid pipes, take care to ensure that
the weight of the lines is not borne by the pump
alone. Utilise supports and/or pipe brackets (see
Figs. 1 + 2, Pos. 7).

Operational voltages and frequencies

- The diameter of the suction line is never permit-
ted to be smaller than the suction/pumping open-
ing of the pump.
- Limit the horizontal length of the suction line and
avoid all possible sources of pressure losses
(elbows, valves, neckings, etc.).
Possible damage to the pump!
In order to protect the pump against
fluid hammers, install the non-return
valve on the pressure side.
In the frequency converter, the testing current
circuits are shielded from the performance cir-
cuits with the aid of a simple insulation
(CEI664-1).
The installer must ensure that the external
testing current circuits (e.g.: pressure sensors,
external control of the setpoint…) are shielded
against any possible contact with people. If the
testing current circuits are to be connected to
the electric circuits corresponding to the safe-
ty specifications of the SELV (TBTS), then an
additional insulation must be installed in order
to comply with the SELV (TBTS) classification.
5.3 Electrical connections
The electrical connections and testing must be
carried out by a licensed electrician and in
accordance with locally applicable standard
specifications.
The electrical properties (frequency, voltage,
nominal current) of the motor frequency convert-
er are indicated on the name plate of the motor/
of the pump. A check is to be made as to whether
the motor frequency converter matches the cur-
rent supply network to which it is intended to be
attached.
The frequency converter is equipped with a motor
protection feature. Constant protection of the
motor and of the pump are ensured by a continu-
ous nominal/actual comparison of the current and
stored data.
In the event of excessively great resistance on the
part of the neutral conductor, a corresponding
protection device must be installed upstream
from the motor frequency converter.
As a basic rule, provide switch amplifiers with
fuses (Type GF) for the protection of the network
(see Figs. 1 + 2, Pos. 11).
If a residual-current-operated protection switch
needs to be installed for personnel protection,
then use a selective universal-current-sensitive
residual-current-operated protection switch
with VDE certificate!
Adjust the safety switch in accordance with the
data specified on the name plate of the fre-
quency converter.
Use connecting cables that meet applicable stan-
dards.
Earth the pump/installation in accordance with
regulations.
English
Installation and operating instructions MHIE 1~16
ATTENTION!

The electrical connection of the frequency con-
verter must correspond to the diagrams contained
in the following table:
The frequency converter could be dam-
aged if connected incorrectly.
The electric cable is never to be allowed to
come into contact with either the pipe or the
pump. Furthermore, it must be completely
shielded against moisture.
Property damage is possible!
Because of operational settings, an incor-
rectly disconnected core in the connec-
tion area could damage the frequency
converter.
• Disconnect the core at both of its end
points from electrical connection
• Pull it off

6 Commissioning
If the pump is supplied separately, i.e. if
it is not integrated in a system that has
been mounted by us, then the configu-
ration type at the time of delivery is
either Mode 1-3 or Mode 2, depending
on the type of pump control desired.
As a reminder: A programming key is
used to switch from Mode 1-3 to Mode 2
(or vice-versa); an after-sales service
employee must be called in.
6.1 Settings
- In manual mode: Mode 1 (see Figs. 1, 2).
The duty point of the pump is reached with the
aid of the potentiometer (see Fig. 9, Pos. 19) by
setting the speed of the motor between 40% and
100% of the maximum speed.
We recommend that the motor speed be set to
70 % for commissioning.
- The pump can be brought to a standstill (frequen-
cy converter under tension) with the remote con-
trol unit (switch).
- In pressure regulation operating mode: Mode 2
(see Figs. 6, 7, 8).
It is possible to regulate the pressure of the
pump through the addition of a pressure sensor
and a diaphragm pressure vessel. The sensor
must exhibit an accuracy of <1% and be used in
a range between 30% and 100% of its measure-
ment range; the reservoir has a useable volume
of at least 8 litres.
No water in the diaphragm pressure vessel.
Pump up the diaphragm pressure vessel to a
pressure that is 0.3 bar less than the control
pressure of the pump (diaphragm pressure ves-
sel and sensor kit included as accessories in the
scope of delivery).
The setpoint for the pressure regulation is speci-
fied in two types:
• The setting of the potentiometer indicates for
the setpoint for a value between 0 and 100% of
the measurement range of the sensor. We rec-
ommend that the potentiometer be set to
100% for commissioning.
• An external signal can be connected (0-10 V or
0-20 mA) for setting the setpoint by remote
control (see Chapter 5.3 - Electrical connec-
tions).
NOTE: The function "Detection of zero volume
flow" makes it possible to stop the pump.
- Via external control per frequency: Mode 3 (see
Fig. 10).
The potentiometer has no function in Mode 3, but
it must nonetheless be set to 100%. The pump is
controlled by an external signal.
Specifications concerning commissioning: see
instruction manual for the pressure boosting sys-
tem.
During normal operation, the status of the LEDs
is as follows: (see Fig. 9, Pos. 17 + 18)
6.2 Preparatory flushing
Because our pumps are hydraulically tested in
the factory, it is possible that there is still water
in their interiors. For reasons of hygiene, it is
therefore recommended that they be flushed
out prior to use in a potable water network.
6.3 Filling - bleeding
Never permit the pump to run dry, not
even for a brief moment.
Pump in intake mode (see Fig. 2)
- Close the stop valve on the pressure side (Pos. 3),
open the inlet/bleeder screw (Pos. 5).
- Gradually open the valve that is located on the
pipework at the entry to the pump (Pos. 2) and
carry out the complete filling of the pump.
Retighten the screw firmly after water begins to
emerge and ventilation is complete.
Danger of injury to personnel!
A jet of water can escape from the ventilation
opening when hot water is being pumped.
Initiate all necessary precautionary measures to
ensure that personnel and the motor/frequency
converter are protected!
Pump in suction mode (see Fig. 1) Two different
cases are possible.
1st case (see Fig. 4.1)
- Close the stop valve on the pressure side
(see Fig. 1, Pos. 3).
- Open the stop valve on suction side (see Fig. 1,
Pos. 2).
- Unscrew the inlet/bleeder screw (see Fig. 1, Pos. 5),
that is located on the pump housing.
- Fill the pump and suction line completely with the
aid of a funnel inserted into the opening.
- The filling procedure is finished when water
escapes and ventilation is complete.
- Screw the inlet/bleeder screw back on.
2nd case (see Fig. 4.2)
The filling can be made easier if a pipe equipped
with a cock (Pos. 12) Ø 1/2" and a funnel
is mounted perpendicularly on the suction line
of the pump.
- Close the stop valve on the pressure side
(see Fig. 1, Pos. 3).
- Open the stop valve on suction side (see Fig. 1,
Pos. 2).
- Open cock (see Fig. 4, Pos. 12) and inlet/bleeder
screw (see Fig. 1, Pos. 5).
- Fill pump and suction line completely, until bub-
ble-free water escapes from the filling opening.
- Close the cock (see Fig. 4, Pos. 12) (it can remain
mounted on the pipe), remove the pipe and screw
the inlet/bleeder screw back in.

6.4 Starting
Depending on the temperature of the fluid and
on the operating cycles of the pump, the sur-
face temperature (pump, motor) may exceed
68°C: mount suitable personnel protection
apparatus as needed.
The pump should not be permitted to be
operated longer than ten minutes with
zero flow when the gate valve is closed
on the pressure side.
We recommend that a minimum flow level of
approximately 10% of the nominal throughput of
the pump be maintained in order to ensure that
no blow hole forms in the upper part of the pump.
- Open the stop valve on the pressure side and start
the pump.
- Check the uniformity of the pressure on the dis-
charge side with the aid of a pressure gauge;
bleed the pump again or refill it in the event of
deviations.
- Check current consumption. The current con-
sumption may not exceed the specification on
the pump shield.
7 Maintenance
The pump(s) must be de-energised and
all non-authorised restarts must be pre-
vented before any maintenance work is
done.
Never undertake maintenance work while the
pump is running. Always keep pump and
motor/frequency converter in clean condition.
When set up in frost-free locations, the pump
should not be emptied, even with prolonged
decommissioning.
To prevent blockage of the shaft and of the
hydraulic apparatus, the pump is to be emptied
during periods of potential frost by unscrewing
the drainage and inlet/bleeding screw (Fig. 1+2,
Pos. 5+6). Screw both screws back in without
tightening them.
Replacement frequencies
NOTE: These can only be regarded as recommen-
dations, because the frequency of replacement is
dependent on operating conditions within the
group involving
• Temperature, pressure and quality of the fluid for
the mechanical seal.
• Pressure and ambient temperature for the motor
and other components.
• Frequency of start-up: continuous or intermittent
operation.

8 Operating faults
De-energise the pump before each
intervention and secure against non-
authorised restarts!
All of the incidents listed below will lead to
a switch-off via the error relay.
De-energise the pump before each intervention.
If the fluid is toxic, corrosive or hazardous for
personnel, then WILO or the authorised repair
company must be informed of the situation.
Clean the pump in such cases in order to ensure
absolute safety for the craftsmen performing
the repairs.
If the pump is at a complete standstill and an intervention is required, disconnect the power supply, wait until the LEDs have gone out completely, eliminate the fault
and reconnect the power supply. If a major fault is present, then an after-sales service employee must be called in.
If the operating fault cannot be rectified, then please
contact your local professional tradesmen or the Wilo
