You are about to install an E.2 Series circulator – a high–

efficiency pump from Armstrong. E.2 Series circulators are

designed for heating and cooling in hydronic, geothermal or

solar systems and circulating water, ethylene or propylene

glycol/water solutions. For pumping domestic (potable) water,

Armstrong recommends the use of circulators with bronze

body construction.

The E.2 Series circulators are extremely efficient and quiet.

They utilize a state of the art permanently lubricated bearing

system designed for many years of trouble-free operation.

They feature a permanent-split capacitor motor with thermal

protection.

1.0 oper ating limits

Maximum operating pressure:

150 psi (1034 kPa)

Maximum operating temperature:

All standard models 230°f (110°c)

Minimum operating temperature:

All standard models 32°f (0°c)

Electrical rating:

For models with T hp motors: 120 v, 1 phase, 60 Hz or

208/240 v, 1 phase, 60 Hz

For models with Q hp motors: 120 v, 1 phase, 60 Hz or

208/240/277 v, 1 phase, 60 Hz

When unpacking the circulator, inspect for any damage that

may have occurred during transit. Check for loose, missing or

damaged parts.

this pump is for indoor use only

Before installing the circulator, proper installation practice

recommends a thorough flush of the hydronic system, ensuring

removal of all foreign materials.

warning

Mount with motor shaft horizontal and terminal box

above centerline (cl) only!

E.2 Series high efficiency

circulator

The circulator is supplied for up-discharge.

For alternate discharge orientation:

1 Loosen the four motor mounting bolts

2 Rotate the volute to match piping orientation

3 Observe flow direction arrow on volute

4 Ensure volute gasket is properly seated

5 Retighten mounting bolts evenly to 5 lb/ft (6.7 N/m)

6 Ensure the impeller spins freely

2.0 electrical wiring

The electrical wiring must be installed in strict accordance with

the Canadian Electrical Code or the U.S. National Electrical

Code, as well as local codes and regulations.

1 Electrical installation should be conducted by a qualified

electrician.

2 The motors of E.2 Series circulators are designed for 60 Hz,

1 phase, 120 v or 240 v service only. (Please refer to the

rating label on the circulator's terminal box to determine the

correct voltage.)

3 Always make sure the electric power is disconnected and

locked out before wiring the circulator.

4 To wire, loosen the screw from the terminal box cover and

remove the screw and cover.

5 Install the appropriate size conduit end to one of the holes on

either side of the terminal box.

6 For 120 v models: Referring to diagram 1 below, connect the

black, hot, (L) and white, neutral, (N) leads of the supply

wire to the black and white motor leads respectively inside

the terminal box. Connect the ground wire to any one of the

motor shaft
