IMPORTANT NOTE TO INSTALLER:
Read carefully before installing and operating the circulator.
Please leave this manual for the owner’s use.
You are about to install a 1070-AP Series circulator – a high-
efficiency pump from Aurora. 1070-AP 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,
Aurora recommends the use of circulators with bronze body
construction.
The 1070-AP Series circulators are extremely efficient and
quiet and use 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.

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.
INSTALLATION:
Before installing the circulator, proper installation practice
recommends a thorough flush of the hydronic system, ensuring
removal of all foreign materials prior to installing the circulator.
Checkthattheflowdirectionofthewaterthroughthehydronic
system matches the arrow on the circulator body. The circulator
is supplied for installation with an up discharge direction.
The 1070-AP Series circulators can be installed to discharge up
or down, horizontally left or right, but the circulator shaft must
remain in the horizontal position. It is recommended that the
circulator be installed such that the terminal box is installed on
the top or side of the motor housing but NOT underneath the
motor housing. The piping can be in a horizontal or vertical run.
Isolation valves should be installed on the discharge and suction
side of the pump to facilitate service.
TERMINAL BOX: If the terminal box is found to
be positioned inconveniently, it can be rotated as required
through 90˚ increments. See examples shown in
“Installation Positions”.
ELECTRICAL WIRING: The electrical wiring must be
installed in strict accordance with the U.S. National Electrical
Code or the Canadian Electrical Code, as well as local codes
and regulations.
a. Electrical installation should be conducted by a qualified
electrician.
b. The motors of 1070-AP Series circulators are designed for
60Hz,1Phase,120Vor240Vserviceonly.(Pleasereferto
the rating label on the circulator’s terminal box to determine
the correct voltage.)
c. Always make sure the electric power is disconnected and
locked out before wiring the circulator.
d. To wire, loosen the screw from the terminal box cover and
remove the screw and cover.
e. Install the appropriate size conduit end to one of the holes
on either side of the terminal box.
f. For 120V models:
• Referring to Diagram 1 on page 2, connect the hot
(black, “L”) and neutral (white, “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 four green ground screws inside the terminal
box(useaminimum18AWGwiresize).

For 208 / 240 / 277V models:
• Referring to Diagram 2 below, connect the black (“L1”)
and blue (“L2”) 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 four green
ground screws inside the terminal box (use a minimum
18AWGwiresize).
g. Replace the terminal box cover.
The motor is thermally protected for your safety so overload
protection is not necessary. All that is required is a fused
plug or circuit breaker in the power line.
Electrical information can be found on the nameplate of
the motor.
START-UP:
a. Before starting up the circulator, proper installation practice
recommends a thorough flush and draining of the hydronic
system, ensuring removal of all foreign materials. Fill the
system with clean water or glycol solution before starting.
b. Air must be completely vented from the system before
starting up the circulator. If the system is not completely
vented of air and the circulator is allowed to run dry, the
mechanical seal will be damaged.
c. When the system has been completely filled and vented,
only then can the pump be started.
1070-AP Series circulators are fitted with permanently
lubricated ball bearings and DO NOT require lubrication.
Disconnect and lock out the power before servicing.
REPLACEMENT OF PUMP FROM EXISTING
INSTALLATION:
1. If valves have been installed on the suction and discharge
sides of the pump, close them before attempting to remove
the circulator from the system. If no valves have been
installed, it may be necessary to drain the system.
 2.For safety, allow water to cool to 100˚F (40˚C) before
draining the system. It is best to leave the drain valve open
while working on the system.
3. Ensure that electric power is disconnected and locked out
before disconnecting the wiring to the circulator. Then,
loosen the screw from the terminal box cover and remove
the screw and cover. Disconnect the supply wires only to
the circulator, leaving the capacitor wires connected.
4. To relieve any residual pressure which may be present in
the pump body, loosen the flange bolts and gently move
the pump body back and forth a bit to allow the pressurized
water to escape.
5. Remove the flange bolts and nuts and then remove the
circulator from the piping.
 6.Install the 1070-AP Series circulator where there
will be sufficient room for inspection and service. It is
recommended that isolation valves be installed on both
the suction and discharge sides of the circulator for future
servicing (this eliminates the need for draining the system
when working on the circulator, for example when replacing
the mechanical seal).
7. Install suction and discharge flanges on the pipe ends. The
use of Teflon tape sealer or a high quality thread sealant is
recommended.
 8.Pipe strain can be minimized by the use of pipe hangers
near the pump, positioned to support the suction and
discharge piping.
To wire the 1070-AP Series circulator, follow steps c
through g in the “Electrical Wiring” section above, noting
that electrical supply and grounding wires must be rated for
atleast194˚F(90˚C).
PREVENTIVE MAINTENANCE – INSPECTION:
Although Aurora long-life circulators are designed to provide
years of worry-free service, it is good maintenance practice to
inspect the entire hydronic system periodically – including the
1070-AP Series circulator – for potential problems. If there is
any evidence of leakage or damage, repair or replace the pump.

1. Turn off the pump leaving it installed in the line.
2. Ensure electrical power is disconnected and locked out.
 3.Close the water supply at the points closest to the pump’s
inlet and outlet.
4. Bleed the water pressure from the pump.
5. Place a pan under the pump to collect the drain water.
 6.Whileholdingthemotorbody,unfastenthefourboltsthat
attach the motor to the pump casing (volute). Start with the
two bottom bolts first and remove them, then slowly loosen
the top two bolts. Allow the water to drain from the bottom
of the pump. When the water has finished draining, remove
the two top bolts. Remove the motor straight out from the
volute, being careful of its attached impeller. The motor is
heavy; do not drop it!
7. Locate the snap bushing in the center of the back of the
motor housing and pry it out with a screwdriver. Insert a
straight-blade screwdriver into the snap bushing hole and
into the slot in the end of the motor shaft to lock the rotor.
 8.While holding the rotor (step 7), unscrew the plastic
impeller off the motor shaft by hand turning it clockwise
(i.e. opposite to most bolts and nuts!). Place the motor on its
back, with its shaft up.
9. Remove the rotary part of the mechanical seal by gently
pulling it off the shaft. If too tight use two small flat bladed
screwdrivers.Gentlypry itofftheshaftby placing theflat
side of the blades onto opposite sides of the mechanical seal.
10. Remove the stationary part of the seal by gently prying it off
the steel faceplate.
11. Remove any corrosion present on the stainless steel motor
shaft with a nonmetallic brush or scrub pad. Do not use a
wire brush or steel wool.
12. Install the new stationary part of the seal into the faceplate:
first, the rubber cup by firmly pressing it down until it
bottoms, then the ceramic disk. The disk face with a circular
groove should be put against the rubber cup (the visible disk
face should be smooth). Press the disk firmly down until it
too bottoms into the rubber cup. The ceramic disk should be
clean. If needed, wipe it with alcohol and a soft cloth.
13. Install the new rotating part of the seal by gently pushing it,
by hand, onto the shaft (graphite ring first) until its steel cap
stops on the shaft.
Checkthat:
a. The height of the steel cap over the ceramic disk is
between0.33"and 0.35"(8.4mmand8.9 mm). Ifitis
more than 0.35" (8.9 mm), then try pushing it farther
down, carefully, but harder.
b. The graphite disk is pressed against the ceramic disk (by
a spring inside it).
If either (a) or (b) is not happening, then contact
Aurora Pump: phone [phone] or e-mail
[email protected].
14. "Lock" again the motor rotor and shaft as per step 7 above,
in order to perform the next step.
15. Fasten the plastic impeller onto the shaft, turning it by hand
counterclockwise until it stops (when it touches the seal's
steel cap). Do not tighten it excessively.
16.Ensure the gasket is properly seated in the pump casing
(volute) gasket groove. Holding the motor body, insert the
impeller straight into the volute. Verify the gasket was not
dislodgedduringinsertionandisstillseatedproperly.Hold
the motor body steady while fastening the four bolts that
attach the motor to the pump casing (volute). Tighten evenly
and diagonally. There should be a small, even gap of about
0.02" (0.5 mm) all around between the motor flange and the
pump casing (volute).
17. Follow the START-UP instructions and check for leaks.
