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, or

stainless steel 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.

208/240/277 v, 1 phase, 60 Hz, or 220-240v, 50Hz

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.

This pump should be installed in a well lit location with good

access.

Installation personnel must be qualified for the task.

All personnel performing installation must wear appropriate

personal protective equipment

(internal)

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 ac-

cordance with the Canadian Electrical Code (Canada)

or the U.S. National Electrical Code (USA),or bs767 1

(Europe) as well as local codes and regulations.

1 Electrical installation should be conducted by a qualified

electrician. Installers should be equipped with proper

personal protective equipment.

2 The motors of e. 2 series circulators are designed for 1 phase,

60 Hz, 120 v 60 Hz, 240 v 60 Hz, 220-240 50 Hz 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.
