OPERATION
4.1 INITIAL STARTUP
The following procedure should be performed for the initial startup of the RO System or to restart the
system if it has been idle and secured for a long term shutdown.
Required Equipment and Materials
Lock-Out and Tag-Out equipment
Personal safety equipment, such as safety glasses and gloves
Prefilter cartridge elements
portable TDS monitor
Chlorine test kit
Portable pH meter
Pre-Startup Checklist:
1.
Verify that the Hand-Off-Auto (HOA) switch on the RO Control Panel is off.
2.
Confirm the storage tank is ready to receive water and the drains are all clear.
3.
Check to ensure there are no repairs or service in progress to the RO unit or down stream
equipment.
4.
Verify that the valves on the RO unit are set up correctly.
5.
Verify the pre treatment equipment is on-line and ready to supply the RO unit.
6.
Test the water quality (TDS, chlorine, temperature, pH) to verify it is within the limits of
the membrane elements. Refer to membrane literature in appendix if necessary.
7.
If the RO membranes were not installed at the factory, they need to be installed now,
before proceeding with the start up. Refer to Section 5.3 for loading instructions.
PRE-START, LOW PRESSURE SYSTEM FLUSHING
New RO membrane elements are shipped with a chemical preservative applied
to the membranes. It is hazardous to your health and will contaminate
product water supplies. It must be flushed from the membranes prior to using
the RO product water.
1.
Verify that the feed water pressure to the RO unit is within 20 to 95 PSIG. If there is no
feed pressure, make sure the main supply valve is opened. (If the pressure is too low,
you may need to install a feed water booster pump to avoid low pressure fault shutdowns.
If the pressure is too high, you must install an automatic pressure regulating valve to
