OPERATING INSTRUCTIONS
3.1
CONTROLS AND INDICATORS
The controls and indicators used in the operation of the system are outlined in the
Appendix (Figure 1.1). The operator must be thoroughly familiar with the controls and
their respective functions for proper operation and in order to maintain the quality of the
permeate and eliminate unnecessary shutdowns.
3.2
INITIAL STARTUP OF REVERSE OSMOSIS SYSTEM
A.
The operator should verify that appropriate pretreatment is in place and
operating satisfactorily. Inappropriate or inoperative pretreatment can damage
the membranes and result in water which does not meet AAMI recommended
standards.
B.
Make all water, electrical, and drain connections according to installation
instructions.
C.
Verify that the Key switch is in the OFF position (see the Reverse Osmosis
Controller, Operating Instructions in the Appendix). Turn on the inlet water and
the electrical power at the remote disconnect. Direct product water to the drain
until proper operation of the system is verified and product quality is known to be
within specifications.
CAUTION
Verify that all RO housing retaining rings are in place and engaged.
D.
Turn on the Key switch and press the power button. Place the controller in the
Direct Feed Mode.
E.
Check for proper pump rotation. Slowly close the pump throttle valve (Figure
1.1) and record the pressure indicated on the PUMP PRESSURE gauge
upstream of the valve. Immediately turn the system off
. DISCONNECT THE
POWER
and switch any two electrical leads in the pump starter. Turn the
system on and again close the pump throttle valve and record the pump
discharge pressure.
Do not run the system for more than a few seconds
with the pump discharge valve closed.
The lead hookup that gave the
highest discharge pressure indicates the correct rotation. (Please refer to the
Pump Installation and Operating Instructions
, included in the Appendix of this
manual for information concerning motor rotation and any other electrical
requirements.)
CAUTION
Do not run the motor for more than 30 seconds backwards or irreversible
pump damage may result. The membrane pressure should not be
allowed to exceed 24.15 bar (350 psig) during the procedure.
F.
Adjust the reject throttle valve (Figure 1.1 in the Appendix) to give the design
product flow indicated on the System Specifications sheet in the Appendix. DO
NOT exceed 24.15 bar (350 psig) membrane pressure.
