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.

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.
