PLUMBING CONNECTIONS: ALL UNITS
1. A 3/4” (1/2” for Model 1100) standard copper water
supply line will need to supply a minimum of 12 gallons per
minute at 30 psi (minimum). A 1” Reduced Pressure Zone
(RPZ) valve is included (except model 1100) and must be
installed with the system per local codes. The installation
diagram follows. The RPZ valve will need to be tested and
certified by a licensed plumber. For all plumbing connections,
especially the PVC connections, be sure to connect the fittings
securely.
DO NOT OVERTIGHTEN FITTINGS!
2. Connect the 3/4” (1/2” for Model 1100) copper water
supply line to the inlet of the RPZ valve.
3. Connect a section of 3/4” (1/2” for Model 1100) copper
pipe to the outlet of the RPZ valve. It is recommended that
union fittings be used on either side of the RPZ valve so that
it can be easily removed should maintenance be required.
4. For 1500 & 1300 Models: Install the inlet of the electric
solenoid valve after the RPZ valve.
5. For 1500 & 1300 Models: Connect the outlet of the
electric solenoid valve to the inlet of the Aqua-Box. The
electric solenoid valve should now be mounted between the
RPZ valve and the Aqua-Box. Ensure the electric solenoid
valve flow arrows, markings are pointed towards the Aqua-
Box. Refer to Electrical Connections below for connecting
the wires of the electric valve.
6. For 1200 & 1100 Models: Connect the outlet of the RPZ
valve to the inlet of the Aqua-Box.
7. A 1” gate valve is supplied for backwashing. Union fittings
are recommended for ease of installation and removal should
maintenance be required. The 1”valve on the discharge side
of the unit should be mounted where employees will not be
closing it when not needed.
8. To insure maximum staff safety, the fluid discharge line from
the Aqua-Box should be plumbed directly to an existing sewer
line. Connect the outlet of the Aqua-Box using minimum 2”
sewer line with an outside vent, per the Southern Building
code. The discharge line can run back up above the Aqua-
Box into a sewer line running along the ceiling if necessary
(Please contact Aqua-Box Technical Support for this type of
installation). In this case, a check valve needs to be added to
prevent fluids from running back into the unit after it has been
turned off. As the Aqua-Box is sealed, a trap is not necessary,
but may be installed without issue.
9. The discharge line must be adequately vented. Failure to
do so may result in pressure buildup in discharge line causing
fluid waste to flow back into the Aqua-Box. A minimum 2”
drain and vent is needed.
