Page: 42 / 81

42
Some systems are shipped WITHOUT the RO Membrane Element. This is to accommodate, for example,
boat builders who install the system well in advance of commissioning the boat and the Parker Hannifin
System.
If the RO Membrane Element has been installed, there will be an Element Serial Number tag
attached to the RO Membrane/Vessel Assembly. Find this serial number tag to ensure that the RO
Membrane Element has been installed.
If the RO Membrane Element Serial Number tag is missing or does not contain a serial number and date,
then immediately contact the company that sold the system to you or Parker Hannifin. Provide Parker
Hannifin with the system serial number and model number of Aqua Duo System.
CAUTION
DO NOT attempt to operate the system without a RO Membrane Element installed in the system, as
extensive damage will result.
9. Ensure that the manual bypass lever located on the side of the 3-Way Product Water Solenoid
Diversion Valve is positioned outward (away from the coil body).
10. Check each hose and tube connection to the system to ensure that the installer has properly
connected and routed each hose and tube. Ensure that there are no kinks or blockages in any
of the hoses or tubes leading to and from the Aqua Duo. Improper routing and any blockage in
any line causes damage to the system.
Do not rely on the installer’s word; check it y ourself.
11. Make sure that the electrical power source, the boat’s circuit breaker, to the system is switched
"OFF."
12. Open the front panel of the Main Power Enclosure. Check all electrical and electronic
connections for proper wiring and attachment.
13. Ensure that the installer has used the proper-sized power wire and Booster Pump wire.
14. Close the Main Power Enclosure front panel.
15. Open the Sea Cock Valve.
16. Open any auxiliary valve within the incoming feed line, Outgoing Brine Discharge Line and
Outgoing Product Water Line.
CAUTION
Caution : Any auxiliary valve in these lines damages the Parker Hannifin System if left closed during
starting and/or operation of the system.
17. If the optional Clean Rinse Valves are installed, ensure that they are positioned properly for
normal operation.
18. Switch the electrical power source to the “ON” position, the boat’s circuit breaker.
