19. On three phase systems, perform a Feed pump motor rotational check. Ask an assistant to view
the fan chapter of the Feed Water
Pump Motor while “jogging” this electric motor.
On three phase ,systems Press the “START/STOP” button; then immediately after the booster pump
starts, press the “START/STOP” button. Ensure that the Feed Water Pump Electric Motor is turning
in the proper rotation.
23.
To start the system, press, the “START/STOP” button. If the system automatically shuts off
immediately or after 20 seconds of operation, this may be due to a system fault. Look at the
Controller to confirm whether a fault has occurred. If Error ID 2 or 3 (High /Low Pressure Error)
appears on the screen, ensure that the system feed line is primed and that there is no air in the
feed water line. Then, restart the system. Initial new system commissioning may require
priming of the feed water up to the Feed Pump inlet and through the pre-filtration to build
sufficient feed water pressure to maintain operation. Refer to the Troubleshooting Section of
this manual.
24.
Although the system is producing “product water,” the “product water” may not be “potable”
for up to 30 minutes. New RO Membrane Elements require operating time to flush storage
chemical from the product water channel. Daily operation requires operating time to flush
dissolved solids from the product water channel. The operating time required to flush the
product water channel is normal for reverse osmosis systems. The salinity of the product water
diminishes gradually and is measured by the salinity probe. When the salinity of the product
water has diminished to the factory setting, the salinity controller will energize the 3-Way
Product Water Diversion Valve. At that instant, product water will be routed to the charcoal
filter, and optional UV sterilizer onward to the potable water storage tank.
25.
Check for the following:
a) Constant feed water flow.
b) Consistent system pressures.
c) Leaks in the system.
d) Unusual noises or other occurrences.
26.
Complete the “ NEW SYSTEM INITIAL READINGS ” form at the end of this chapter.
27.
Prior to stopping the system, determine if the system will be stored for a period of time or if it
will be turned over to the owner and operated regularly. Failure to properly flush and/or store
the system will lead to premature fouling or drying out of the RO Membrane Element, which
is not covered by the Parker Hannifin Warranty and is the liability of the person
commissioning the system.
a) If the system will be operated within the next two weeks, no action is necessary. However, if
the system will be exposed to freezing temperatures, you must perform winterizing procedures.
Freezing temperatures will cause extensive damage if the system is not properly protected.
b) If the system will not be operated within the next two weeks, perform a freshwater flush. If the
Parker Hannifin Automatic Freshwater Flush is installed, ensure that the potable water storage
tank has potable water for the freshwater flush to utilize in rinsing the system. If the system
does not include an automatic freshwater flush, then perform a manual freshwater flush.
