Armstrong ARMflo E Series Installation And Operating Instructions

READ CAREFULLY BEFORE INSTALLING & OPERATING THE CIRCULATOR
INSTALLER
You are about to install an ARMflo E Series circulator - a high-efficiency pump from Armstrong. ARMflo E Series
circulators are designed for heating and cooling in hydronic, geothermal or solar systems, circulating water or
ethylene or propylene glycol/water solutions. For pumping domestic (potable) water, Armstrong recommends the use
of circulators with bronze body construction.
The ARMflo E Series circulators are extremely efficient and quiet and 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.

OPERATING LIMITS

 Maximum operating pressure:
 Maximum operating temperature: All Standard Models
 Electrical Rating: For models with 1/6 hp motors: 120 V, 1 Phase, 60 Hz or 208 / 240 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.
Before installing the circulator, proper installation practice recommends a thorough flush of the hydronic system,
ensuring removal of all foreign materials.
