GENERAL

In all AGEplus circulators, Pressure Loss Compensation (P.L.C.) is included

in the control, which means that the circulator does not follow a constant

differential pressure but takes into account the decreasing pressure needs

at decreasing flow. This setting is in the auto controlling mode. See Fig. 7.

SIGNALS

AGEplus circulators have two LED's on the terminal box for status indica-

tion. 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. 8.

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.

SERVICE / MAINTENANCE

Armstrong's AGEplus 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 . AGEplus circulators are despatched fully assembled. AGEplus

circulators are packed for transport by mornal road, sea and air

carriers.

b. Handling

i. Crushing Hazard.

Ii. When lifting an AGEplus 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 AGEplus 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 AGEplus 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.
