Armstrong Legacy AG Series User manual

Page 1 of 2
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
with water v =1mm2/s at 20ºC.
Suitable for water impurity up to 5mg/dm3.
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 adequatelyqualified.
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

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 untilall air within
the system has been removed. Venting is best
done in manual speed 4.
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

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.

GENERAL
In all AGE circulators, Pressure Loss Compensation (P.L.C.) is included in
the control, which means that the circulator does not follow a constant differ-
ential pressure but takes into account the decreasing pressure needs at
decreasing flow. This setting isin the auto controlling mode. See fig. 4.

Description
ERROR SIGNALS
The red light on the back of the terminal box will, in case of an error, indicate
the type of error detected by the electronic. Approximately every minute the
light will blink a number of times, except 31-07, which is permanently illumi-
nated in the event of a fault.

1 Under voltage from the power supply
2 Over voltage from the power supply
3 Instantaneous over current

ERROR RELAY
With the exception of the 32-07, the AGE
has a fault relay. The relay has both a NC
and a NO connecting. See fig. 3.

SERVICE / MAINTENANCE
Armstrong’s AGE Series range of glandless circulators is virtually
maintenance free and in a well designed system should give many years of
trouble free operation.
If motor shaft is seized as a result of a long period without use or due to
accumulation of impurities, it should be freed. Insert a screwdriver through
the venting plughole and into the slot in the end of the shaft and rotate.
Please note: Any repairs required to the internal electrical parts of the circu-
lator, are to be carried out by an Armstrong approved service organisation.
Transport, Handling and Storage Instructions
a. Transport.
i . AGE circulators are despatched fully assembled. AGE
circulators are packed for transport by mornal road, sea and air
carriers.
b. Handling
i. Crushing Hazard.
Ii. When lifting an AGE circulator above a weight of 25 kg,
use lifting equipment haveing a safe working load rating
suitable for the load specified. Use suitable slings for lifting any
circulator..
c. Storage
i. Short term Storage (six weeks). If the AGE circulator is not to be
installed immediately after unpacking, then it is to be be stored in
a cool dry dust free location.
Ii. Long term storage. If the AGE circulator is not to be installed for
period of longer than six weeks after receipt on site, then it is to
be retained in its packing case. If the casing case is disposed of,
then the inlet and outlet connections are to be blanked off with
suitable clean covers to prevent ingress of damaging solids.
