ELECTRONIC CONTROL BOX
WARNING: DO NOT USE AN EXTENSION CORD TO
RUN ELECTRICAL POWER TO THE SYSTEM.
WARNING: ELECTRICAL CONNECTIONS MUST
COMPLY WITH ALL LOCAL CODES.
An Electronic Control Box (Item 24) connected to the
solenoid valve regulates system operation. The control
box contains a circuit board, terminal connections, and a
fuse.
The control box operates at 24VAC 50/60Hz. A 24V
transformer is provided with the system (Item 25). The
transformer is plugged into a grounded outlet.
1. Mount the control box in a visible location close to
an electrical outlet and where the ON/OFF switch is
easily accessible for operation.
2. Unscrew the Box Cover Screws and pull the cover
clear to expose the circuit board and terminal strip.
NOTE:
All terminal callouts in the following steps refer
to the circuit board shown in Figure 5.

CAUTION:
Wiring connections must be secure to
ensure the system operates properly.
To connect a wire to the terminal:
a. Thread the wire through the wire nut and
into the control box.
b. Loosen the screw above the terminal connector.
c. Insert the wire into the connector as far as it will
go. If the wire does not go in easily, loosen the
connector screw until the wire will go in.
d. Tighten the connector screw sufficiently to keep
the wire from pulling out of the connector.
4. Connect the power cord wires from the transformer
to terminals 1 and 2 (24VAC INPUT) on the terminal
block.
5. Connect the wires from the solenoid to terminals 3
and 4 (INLET VALVE) on the terminal block.
6.
CAUTION:
If the AquaSafe RO system is located
downstream from any device that could cut off the
water supply to the system, i.e., water softener or
filter, an automatic power disconnect, or
Pretreatment (P/T) Lockout Device must be used.
Connect a Pretreatment Lockout Device (P/T),
Automatic Shut-off, and/or Auxiliary Relay as
described on Page 6.
7. Tighten the nut on the strain relief to hold the wires
in
place.
8.
CAUTION:
Verify that all connections are secure
before
proceeding.
Install the box cover and tighten the screws.
9.
CAUTION:
Verify that the Power Switch is in the
“OFF” position before continuing with the installation.
Connect the transformer to the electrical outlet.
10. Turn on the Aquasafe RO System by moving the
Power Switch to the “ON” position.
11. Open source water shut-off valve. Let the system
run for five minutes and check for leaks. Correct
leaks as necessary.
12. Confirm that the system is producing water. System
will be sending water to the drain.
