This installation guide gives basic instructions which are to be observed
during installation, operation and maintenance of the circulator. It is therefore
imperative that this manual is read by the responsible operator prior to the
installation and should always be kept available at the site.
It is not only the general safety instructions under the "Safety" section that
are to be observed but also the specific information provided throughout this
guide.
APPLICATION
The AGE SERIES circulators are used in all types of heating systems. By
use of the advanced internal speed control, the electronic automatic
adjustment the circulator performance according to system needs. This
feature gives both great electrical and thermal savings together with reduced
noise level in the installation.
CIRCULATOR MEDIUM
Clean, non aggressive and non explosive fluids without any solids or fibres.
Kinematic viscosity: Max. 10mm2/s. Higher viscosity will cause circulator to
regulate improperly. Capacities shown on the data sheets are measured

Suitable for water impurity up to 5mg/dm
Please note: If any liquid other than water is being circulated, we
recommend that you contact our representative as the circulator
characteristics may change.

SAFETY
- The surface temperature might be hot.
- When venting the circulator (fig. 6), it could result in a slight
escape of hot water or steam!
- Circulator should be wired according to the existing regulations
- The circulator must always be earthed..
- All the wires must be disconnected before any work is
carried out on the circulator.
Personnel qualification and training
Personnel responsible for operation, maintenance, inspection and
installation of the circulator must be adequately qualified.
The person responsible for the complete installation must ensure that the
contents of this manual are fully understood by any personnel working on
the system.
INSTALLATION
1.
The circulator should always be installed with the circulator shaft
horizontal (See fig. 1). Direction of flow through the circulator casing is
indicated by an arrow located on the casing.
2.
If terminal box is to be repositioned by rotating the motor, care must be

taken to ensure the casing 0-ring is correctly positioned.
3.
Ensure pipework alignment and adequately supported to both the
circulator and pipework. Sharp bends should be avoided nearby the
circulator.
4.
If the circulator is mounted in vertical pipework, flow should be
upwards. If flow is downwards, an air-vent must be fitted at the highest
point before circulator suction.
5.
Circulator should never be allowed to operate against a closed valve
for more then a few minutes at the time.
6.
To avoid accumulation of impurities in the circulator, make sure that it is
not mounted at the lowest point in a system.
7.
It is recommended that isolating valves be fitted either side of the
circulator.
8.
Before installing a new pump the system should be thoroughly flushed

ELECTRICAL CONNECTION
Electrical data is shown on the nameplate. The
circulator needs no external protection but must
be earthed.How to connect the wires can be
VENTING
Before start up of the circulator, fill the system
and vent the circulator thoroughly. Venting can
be achieved by loosening the plug positioned in
centre of nameplate (See fig. 6). This process
should be repeated periodically until all air within
the system has been removed. Venting is best
done in manual speed 4.
DUTY CONTROL
There are two modes for controlling the circulators.
• Controlled to follow a specific defined differential pressure at different
flows (auto).
• Controlled to follow constant speed for systems with constant demand (1-4).
Setting is done via the rotating button on the top of the terminal box.
