1.0 installation
For convenience, Armstrong circulators generally are installed
in vertical pipelines, but may be changed easily on the job for
horizontal pipelines or for opposite flow directions. To make the
change, remove the body capscrews, taking care body gasket is
kept in position, and rotate body to desired direction at 90° or
180° from the original position..
With the arrow on the body pointing in direction of the flow,
insert body capscrews and tighten evenly. On models s25 to
s57, h32 to h5 4 and series 1050 (1b to 2b), a gap between the
bearing bracket and pump body (volute) is normal. Do no over
tighten body capscrews! Turn pump shaft manually at coupler
to make sure shaft turns freely and impeller does not rub in
body. Always install with motor shaft in a horizontal position
with pump oil cups or oil well cover on top.
Models s25 to s46 and h32 to h41 are shipped for downward
discharge. All other models are shipped for upward discharge
as pumps of this size usually are installed in an upward
direction on hydronic systems, so the point of zero pressure
change - namely, the compression tank connection - can be
made easily to the system on the suction side of the circulator.
The pump should be installed in a position to permit proper
lubrication and servicing. Motor and bearing brackets are to be
kept free of insulation. Pump and motor unit are designed to be
supported by the in-line piping only. Do not support in any oth-
er manner. A height of approximately four feet above the floor
is recommended. When placing the pump between flanges,
tighten flange bolts evenly and do not tighten excessively.

Gate valves should be installed on the discharge and suction
side of the pump to facilitate service. On larger pump sizes, a
check valve should be located on the discharge side of pump
between the pump body and the gate valve to prevent damage
due to water hammer.
2.0 system cleanliness
Before starting the pump, the system must be thoroughly
cleaned, flushed and drained, then replenished with clean
liquid. Welding slag and other foreign materials, 'stopleak'
and cleaning compounds, excessive or improper water treat-
ment - all are detrimental to the pump. Warranty will be void if
any of these conditions are allowed to exist. (Refer to File no.
6090.645 design and care of closed hydronic systems.)
3 .0 starting up
The pump must be fully primed on start-up. Fill system piping
and pump body with liquid and vent complete system, turning
pump by hand to dislodge air from body. Make sure fittings and
drain valves are airtight, then add any additional fill required.
Check motor against available electric supply, then start pump
making sure rotation is correct. When viewed from motor end,
rotation is counter-clockwise on models s25 to s46 and h32 to
h41. On all other models, rotation is clockwise. If pressure does
not develop, stop pump, re-check, vent and fill. Never attempt
to fill the system when the pump is running
4 .0 lubrication
caution:
Do not put oil in the maintenance free circulators. These
models contain MF in their item numbers and are labelled:
'this bearing assembly contains permanently lubricated
bearings and does not need any oiling or greasing'.
