Initial Water Fill/Adjusting RO Timer
- You package is shipped with all water drained. The water
receiver must be filled with filtered water (reverse osmosis filter) prior to operating the compressor
unit:
•
Ensure that the make-up water feed line is installed and the ball valve is open.
•
Engage the Emergency Stop button to avoid accidental operation of the compressor.
•
Disconnect package from electrical power.
•
Select a suitable water fill cycle – see RO Filter System, Section 8, for details on operating
and adjusting the PLC and its timing operation. Under normal conditions, the 4 hour-fill cycle
would be adequate. Note the current (or desired) running cycle setting on the PLC – it
must be reset after completing the filling operation.
•
Reconnect package to electrical power.
•
Toggle PLC “run/stop” mode switch off and on to reset the timer and start the selected fill
cycle. After the “on” (fill) cycle times out, the “off” (rest) cycle will follow. If necessary, the
mode switch can be cycled at any time to reset the timer and re-start a new fill cycle.
•
After the tank is filled to the proper level (half-way up the reservoir-mounted sight tube),
disconnect electrical power, and reconnect the original (or desired) running timer cycle
settings on the PLC.
•
Re-connect package to electrical power and disengage the Emergency Stop button.
