3.3 Daily Start-Up and Operation Checklist

NOTE:

This section may be copied for placement on the 23G machine.

CAUTION:

HAND mode is for diagnostic test and CIP. It should not be operated while

unsupervised in this mode.

1. Verify that all feedwater valves and outlet valves in the permeate

and concentrate plumbing are open. At least 20 psi (1.4 bar)

dynamic feed line pressure is required to prevent damage to pump.

2. Make sure the ECM-100 is plugged into an appropriate circuit and

the LCD screen is active.

3. If the feedwater pH is being adjusted for membrane compatibility or

scale inhibition, verify that the chemical feed pump power switch is

on.

NOTE:

If necessary, refer to Section 3.1 for further information on feedwater

preparation.

4. Verify that the ECM-100 operating mode is AUTO. The machine

operates independently of external controls, such as tank float

switch and pretreatment lockout signal, in the HAND mode. In the

AUTO mode, the machine operates according to signals from pre-

or post- treatment equipment, tank float switches, etc.

5. Press the ON key on the ECM-100. After a short delay, the high-

pressure pump will start. Alarms may occur during the first minute

of operation as the RO machine operation stabilizes. Alarms may

be bypassed and muted until the alarms clear. If alarms persist,

address the specified alarm condition shown on the LCD screen

according to the Troubleshooting Guide (Section 7.0).

6. Verify that water is flowing from the permeate outlet. For dialysis

applications verify the water quality to ensure it meets the current

applicable quality standards. Per the AAMI standards, “It is the

responsibility of the attending physician to ensure the water quality

is appropriate.”

7. The machine is now operating. If a pH buffer is being used with the

pH control of the ECM, readjust pump if necessary for a slowly

dropping pH reading while the injection pump is on. The control

range for the buffer pump operation is from 1.8 to 0.8 less than the

high pH alarm setting.
