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 is in the auto controlling mode. See fig. 4.

SIGNALS

AGE circulators have two LED's on the terminal box for status indication.

Power to the circulator is indicated with the green LED. The red LED will

be on if the circulator detect a fault. Reset is carried out by switching the

mains supply off for 5 sec. and then on again. See fig. 5.

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.

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.
