LC <strong>Manual</strong> 11/02 Rev. 3 OPERATING INSTRUCTIONS<br />
3.1 CONTROLS AND INDICATORS<br />
3.0 OPERATING INSTRUCTIONS<br />
The controls <strong>and</strong> indicators used in the operation of the system are outlined in the MC10<br />
RO Controller manual located in the Appendix. The operator must be thoroughly familiar<br />
with the controls <strong>and</strong> their respective functions <strong>for</strong> proper operation <strong>and</strong> in order to<br />
maintain the quality of the product <strong>and</strong> eliminate unnecessary shutdowns.<br />
3.2 INITIAL STARTUP OF REVERSE OSMOSIS SYSTEM<br />
CAUTION<br />
CAUTION<br />
CAUTION<br />
CAUTION<br />
Verify that all RO pressure vessel end cap retaining “U” pins are in place<br />
<strong>and</strong> secure.<br />
Do not run the motor <strong>for</strong> more than 30 seconds backwards or irreversible<br />
pump damage may result.<br />
The membrane feed pressure should not be allowed to exceed 225 psig at<br />
any time during operation.<br />
A. The operator should verify that appropriate pretreatment is in place <strong>and</strong> operating<br />
satisfactorily. Inappropriate or inoperative pretreatment can damage the<br />
membranes.<br />
B. Make all water, electrical, <strong>and</strong> drain connections according to installation<br />
instructions.<br />
C. Divert the outlet of the product water to a convenient drain.<br />
D. Turn on the feed water <strong>and</strong> the electrical power. With product water diverted to<br />
drain, fully open the reject throttling valve <strong>and</strong> close the reject recirculation<br />
throttling valve.<br />
E. Place the controller in the DIRECT FEED mode (refer to the Reverse Osmosis<br />
Controller manual in the Appendix <strong>for</strong> detailed instructions). Press the SYSTEM<br />
START button on the controller keypad to start the system, after a fifteen-second<br />
delay the pump should start.<br />
F. Check <strong>for</strong> proper pump rotation. (Please refer to the Pump In<strong>for</strong>mation, included<br />
in the Appendix of this manual <strong>for</strong> in<strong>for</strong>mation concerning motor rotation <strong>and</strong> any<br />
other electrical requirements.)<br />
G. Set the reject recirculation flow to zero, but do not exceed 225 psig pressure to<br />
the membranes. Open the reject valve further if necessary to avoid over<br />
pressuring the system.<br />
Do not use reject recirculation option <strong>for</strong> the first 4 hours of operation to<br />
speed flush up of the system.<br />
