Fig. 1. Mounting the AquaPUMP variable speed circulator
Arrows on the pump housing indicate the liquid flow direction
through the pump.
1.
Fit the two gaskets supplied when the pump is
mounted in the pipe.
2.
Install the pump with the motor shaft horizontal (see
Fig. 1).
3.3 CONTROL BOX POSITIONS
The orientation of the display can be adjusted by removing
four screws that attach the motor to the pump housing (see
Fig. 2). Pump must be isolated from the system when making
this adjustments as this will open the system to the
atmosphere.
Fig. 2. Control box position (The inverted pump will work, just
reading the panel upside down is not recommended)
Ensure the gasket is intact and seated before evenly
retightening the mounting screw to 4.5-5.5 lb/ft (6-7.5 Nm).
WARNING
The pumped liquid may be scalding hot and under
high pressure. Drain the system or close the isolating
valves on either side of the pump before the screws
are removed.
CAUTION
After the position of the control box has been rotated,
refill the pump with system liquid before startup.
4. ELECTRICAL CONNECTION
4.1 POWER SUPPLY
The electrical wiring must be installed strictly in accordance
with national electrical codes, local codes and regulations.
1.
Electrical installation should be conducted by a quali-
fied electrician.
2.
Always make sure electric power is disconnected
before wiring the circulator.
The motor is designed for 60 Hz, 1 phase, 115 volt power.
Wire shall be 14 to 16 gauge solid wire or 16 to 18 gauge
stranded wire.
To connect, loosen the screw from the wiring box cover and
remove the screw and cover.
Install a 1/2” NPT strain relief fitting (not included) for the
power wiring in the large access hole provided on the right
side of the box.
Insert the power wires through the fitting and secure the
wires.
Strip 3/16” of insulation from the ends of the three wires to
be connected.
To insert the wires into the terminal strip, press the terminal
lever forward firmly. Insert the stripped wire into the opening
and release the lever (see Fig. 3). Tug on the wire gently to
ensure it is secured.
Fig. 3. Terminal strip
Connect the hot wire to terminal “L1”, the neutral wire to
terminal “L2/N”, and the ground wire to terminal (see Fig. 4).
Replace the wiring box cover and tighten screw, unless you
plan to use analog input (see section 4.2).
The pump is thermally protected 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 side of the wiring box.

The electrical connections and protection must be carried
out in accordance with National Electric codes.
