• Warm water heating systems
• Cooling and cold water circuits
• Closed industrial circulation systems
Do not use the pumps Quantum series

• Flow media:
• Heating water
• Water/glycol mixture with up to 50%
glycol. If glycol is added, the flow data is
to be corrected in accordance with the
higher viscosity. Only brand products with
anti-corrosion inhibitors should be used. The
manufacturer's instructions must always be
strictly adhered to.
2. Safety
These instructions contain important information
which must be followed when installing and
operating the pump. These operating instructions
must therefore be read before assembly and
commissioning by the installer and the respon-
sible operator.
Both the general safety instructions in the "Safety
precautions" section and those in subsequent
sections indicated by danger symbols should be
carefully observed.
2.1.
Danger symbols used in these
operating instructions
Safety precautions in these operating instructions
which, if not followed, could cause personal injury
are indicated by the symbol:

The following symbol is used to indicate that by
ignoring the relevant safety instructions, damage
could be caused to the pump/machinery and its
functions:
2.2 Risks incurred by failure to comply
with the safety precautions
Failure to comply with the safety precautions
could result in personal injury or damage to the
pump or installation.
Failure to comply with the safety precautions
could also invalidate any claim for damages.
In particular, lack of care may lead to problems
such as:
• Failure of impor tant pump or machinery
functions
• Injury resulting from electrical or mechanical
factors.
2.3 Safety precautions for the operator
Existing regulations for the prevention of acci-
dents must be followed.

2.4 Safety information for inspection and
assembly
The operator is responsible for ensuring that
inspection and assembly are carried out by autho-
rized and qualified personnel who have studied
the operating instructions closely.
Work on the pump/machinery should only be
carried out when the machine has been brought
to a standstill.
2.5 Unauthorized modification and ma-
nufacture of spare parts
Alterations to the pump or installation may only
be carried out with the manufacturer's consent.
The use of original spare parts and accessories
authorized by the manufacturer will ensure safety.
The use of any other parts may invalidate claims
invoking the liability of the manufacturer for any
consequences.
2.6 Unauthorized operating methods
The operating safety of the pump or installation
supplied can only be guaranteed if it is used in
accordance with paragraph 1 of the operating
instructions. The limiting values given in the ca-
talogue or data sheet must neither be exceeded
nor allowed to fall below those specified.
¡ATTENTION!
3 Transport and interim storage
The pump must be protected
¡ATTENTION!
against moisture and physical
damage. In the case of
transport and interim storage
the pump may not be exposed
to temperatures outside the
range -10°C to +50°C.
4. Product and accessory
description
4.1 Pump description (figs 1a, 1b)
The Quantum high efficiency pump is a series
of glandless pumps with Electronic Commutated
Motor (ECM) technology and built-in differential
pressure control.
On the motor housing there is an axial control
module (fig. 1a, pos. 1) which sets the pump's
differential pressure to a set value that can be
varied within the control range. Depending on the
control system involved, the differential pressure
is subject to different criteria.
However, regardless of the control system the
pump constantly adapts to changing system
power requirements, as it is especially the case
when using thermostatic valves or mixers.
The main benefits of electronic control are:
• It saves energy whilst at the same time reducing
operating costs.
• It reduces noise caused by the flow.
• It does not require overflow valves.
4.1.1 Differential-pressure control
systems
The control systems which can be selected are:
∆
p-v: The electronics increase the pump's
differential pressure set value in a straight line
between 1/2 Hs and Hs.The differential pressure
set value H increases or decreases in accordance
with the transporting capacity (fig. 7). Basic
factory setting.
∆
p-c: The electronics keep the differential
pressure generated by the pump above the
permissible delivery flow range constantly at the
set differential pressure set value Hs up to the
maximum characteristic (fig. 8).
4.1.2 Other energy-saving operating
modes
• Regulator mode operation: The speed of the
pump is kept at a constant speed between nmin
and nmax (fig. 9). The regulator mode deactivates
the differential pressure control.
• In the «auto» operating mode (factory setting)
the pump is able to recognize a minimum system
heat output requirement due to a sustained drop
in the flow medium temperature and then switch
to «Autopilot» night setback mode. If the heat
output requirement rises, the pump automatically
switches to standard mode. This setting ensures
that the pump's energy consumption is reduced
to a minimum and in most cases is the optimum
setting.
The «Autopilot» automatic
¡ATTENTION!
night setback mode may
only be enabled if the unit
has been hydraulically com-
pensated. If this is not done,
undersupplied unit parts
could freeze in the event
of frost.
