MOTOR HEAD MODULEX HYBRID
1 - Introduction on functions
The ANTARES MODULEX UPMH circulation pump is an intelligent frequency conversion circulator
with integrated electronic differential pressure control, with the possibility of setting the regulation
module and the head (differential pressure). The differential pressure is controlled by the pump
speed. The motor stator is fully shielded and the rotating parts are immersed in clean water, playing
an important role in cooling and in lubrication during operation. The shielding sleeve of the electric
pump adopts a thin-walled structure to completely shield the internal stator from water in the
engine; the traditional mechanical seal structure is eliminated and the problem of water leakage
of the conventional pump is solved. The rotating parts consist of ceramic bearings and ceramic
rotating shafts, wear resistant and lubricated with clean water, wich cool the engine and reduce its
noise. The pump will not overload during full operation performance. It can be generally maintained
free as long as used correctly.

2 - Replacement instructions
2.1 - Preliminary checks on the general status of the old circulator to be replaced
●Verify with a voltmeter that the voltage is present on the power supply
terminals of the motor, measuring the presence of correct voltage.
●Check the inside of the terminal box the presence of burns and the status
of the capacitor.
●Check the electrical continuity of the windings to determine any
interruptions or burns
●Measure the insulation resitance
●The test is considered passed if the insulation resitance is more than 10 Ω.
1) Make sure that the malfunction is not due to other causes.
2) Make sure that the circulator is not blocked by grime. If the release screw is present, proceed with a
screwdriver as shown:
With a large screwdriver
you unscrew the cap.
Then, with a small one
you move the rotor of the
circulator to the right and
left, which acts on the
cut accessible under the
removed cap.

IF THE OLD CIRCULATOR IS IRREPARABLY COMPROMISED, PROCEED TO REPLACE
THE MOTOR AS PER THE FOLLOWING INSTRUCTIONS:
PRELIMINARY CHECKS FOR INTERCHANGEABILITY
WHEELBASE OF THE FIXING FLANGE
Check carefully that the purchased product meets the 3 conditions defined above of
the old circulator to be replaced.
Usually the detail on the badge shows first the diameter of the fittings and then the delivery head.
It is preferable to use motors with similar or higher metric delivery than the old circulator. The motor –
circulator with AUTO ADAPT function, is self-regulating and therefore reduces its power in relation to the
real and variable needs of the system.
●8 mt model type (art P.121.80) in replacement of 5, 6, 7 and 8 mt circulators.

3 - Instructions for motor replacement
A. Disconnect the nain power switch of the
electric system.
B. Make sure there is a real power failure
using a voltmeter.
C. Disconnect the supply wires of the old
circulator
D. Close the power tap oft he water in the
heating system
E. If the circulator is equipped with
shut-off valves at the inlet and outlet, close
it. If there are none, the system must be
completely emptied.
F. Once empty with appropriate Allen key
diam 4-5 with T handle :
loosen the four bolts (in some cases only
two) fixing the motor to the pump body.
G. Let out the remaining water.
H. Loosen and remove the fixing bolts
completely, witout throwing them away,
and remove the faulty motor.
I. Insert the new motor in flange, inserting
one or two washers provided in the package
between the motor flange and the body.
ATTENTION: in some models of old circulator
bodies it is necessary to apply a second washer
to avoid the impeller rubbing on the pump body.
It is therefore necessary, before fixing the bolts,
to check in advance that the coupling does not
cause the impeller to rub on the body, in which
case you will insert a second spacer washer.
Most frequently encountered when using 1 mm
washers.
●Wilo: no washers
●Grundfos: - Bodies in cast iron: no washers
- Bodies in plastic: 1 or 2 washers
J. Insert the bolts and tighten them
completely
K. Use the appropriate Allen key to tighten the
bolts progressively with the corresponding
counter elements.
L. Open the circulator shut-off valves, if
present.
M. Open the water supply tap of the heating
system until the defined filling is reached.
N. Check that there are no leaks between
pump flange and motor.
O. Connect the wiring in the supply box of the
new motor.
P. At the end oft he motor replacement it is
advisable to set correctly the function of
the circulator with button (fig. 1 ref. 6) as
specified in the following pages.
The function of the motor/circulator is factory
pre-set in CS mode - constant speed.
If after having removed the motor, you notice on the old body of the circulator the
presence of sludge, fine sand due to the crystallization formed by mineral salts
(manganese, iron, calcium or others) or similar dirt, it is advisable to perform or
to have performed the total washing of the system, in order to avoid a possible
and repeated blockage of the motor.

4.4.1 PWM input signal (P1 heating systems for Modulex Hybrid models)
The pump speed is controlled according to the signal PWM input
signal, when connected.
In PWM mode, the rotation speed of the pump is regulated acording
to the input signal (PWM).
If there is no PWM signal or cable is not connected, the pump
operation is controlled by internal logic.
At high PWM signal rates (duty cycles), a hysteresis prevents the circulation pump from
starting and stoping if the input signal fluctuates around the change point. At low PWM
signal rates the speed of the circulation pump is high for safety reasons. In the event of
cable breakage in a system with a gas boiler, the circulation pump will continue to run at
maximum speed to transfer heat from the primary heat exchanger.
