OPERATING INSTRUCTIONS
3.1
CONTROLS AND INDICATORS
The controls and indicators used in the operation of the system are outlined in the
Appendix. 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, otherwise the RO membranes will become fouled rapidly.
B.
Make all water, electrical and drain connections according to installation
instructions.
C.
Be sure that the controller is turned off.
D.
Turn on the inlet water and the electrical power at the remote disconnect. Direct
product water to the sewer until proper operation of the system is verified and
product quality is known to be within specifications.
CAUTION
Check to verify all RO housing retaining rings are in place and engaged.
E.
Close the reject recirculation valve.
F.
Open the reject valve completely.
G.
Open the pump throttle valve one (1) turn.
H.
Turn the on/off switch to "ON".
I.
Check to verify the pump motor is rotating in the proper direction. Please refer to
the
Pump Information
in the Appendix for information concerning motor rotation
and any other electrical connections.
CAUTION
Do not run the motor for more than 30 seconds backwards or irreversible
pump damage may result.
J.
If your RO system is equipped with the Reject Recirculation Option, set the reject
recirculation flow to zero, but DO NOT exceed pressure to membrane limits.
Open the reject valve further if necessary to avoid over pressuring the system.
CAUTION
Do not use reject recirculation option for the first 24 hours of operation to
avoid recirculating the preservative chemicals.
K.
Check for plumbing leaks and make appropriate repairs as necessary. All
systems are leak checked at the factory but vibration during transit can cause
new leaks to develop.
