5.5 Semi-Annual requirements
1. Tighten all electrical screws in the control box.
NOTE:
Disconnect from both sources of power prior to opening control box.
2. Tighten high voltage wires to motor starter.
5.6 Annual Requirements
The actions below should be performed in addition to the monthly
requirements.
1. An AAMI Water Quality Analysis of the product water should be
conducted at least yearly.
2. Check the ECM monitoring for accuracy. Recalibrate as necessary.
3. Check the instrumentation for correct functioning.
4. Check the valves for correct operation.
5. Check the tubing and fittings for leaks or wear.
6. Check the switches and lights for correct operation.
5.7 Flushing
NOTE:
If the machine is to be turned off for more than 4 hours, it should be
programmed to flush to drain for 15 minutes every 4 hours. This should
minimize the growth potential of biological components in the machine. An
AUTO-ON period can be set in the timer Preset Menu (03) of the ECM-
100 to prevent water from stagnating. Menu (12) must also be set to
permeate divert.
The machine should be flushed daily to remove sediment from membrane
surfaces. For flushing during on-line operation, all Mar Cor Purification
23G machines are equipped with an Autoflush system, which
automatically increases the concentrate flow rate on an intermittent basis.
1. To manually flush the unit, open the machine concentrate valve so
the concentrate flow rate is 20 to 30% higher than during normal
operation. Operate for 10 to 20 minutes and close concentrate
valve.
