ALL ELECTRICAL CONNECTIONS TO THE SYSTEM SHOULD MEET LOCAL CODE AND
DONE BY A QUALIFIED ELECTRICIAN.
Final set-up of your RO system will be dependent upon the TDS of your feed water.
Make sure that
you specify the TDS of your feed water at the time the unit is ordered.
4.1 Initial start up and flushing of the system
•
Turn on the feed water valve to the system and check the connection for leaks. Do not
proceed further until all leaks are fixed. The available inlet (raw) line pressure should now
register on the pre-filter pressure gauge. 60 psi is optimal.
•
Turn on the 120-vac power. The control HMI and the flow meters will turn on. Press the on/off
button on the controller for 2 seconds to disable the RO control system.
Do not turn on the pump power at this stage.
•
Fully open the recycle and waste control valves. See fig 3a & 3b
•
Open the auto-flush valve by moving the lever to manual (Fig. 6) and turning the handle 90
degrees as indicated by the positioning indicator on top of the valve actuator.
•
Move the lever on the permeate valve from
“auto” to “manual” and turn the valve 90
degrees counter-clockwise so that the
permeate Hi TDS divert port is open.
•
Move the lever of the feed inlet valve to the
manual position. Slowly turn the valve until you
hear water flowing. Do not fully open the valve
at this point.
•
Allow the feed water to fill slowly into the
system. This process will expedite the air
removal from the RO system.
•
Once the water starts to run out of the system
to drain, close the auto-flush valve by turning
the knob in the opposite direction. Once the
indicator is back in the original position,
let the
system run to drain for 2 minutes with the
waste valve fully open.
•
The reject flow meter should be registering the flow to drain.
•
Close the waste control valve. This will allow the feed pressure to rise and force more air
from the system. Water should be exiting the system through the permeate divert port only.
•
The permeate flow meter should be registering a flow at this point.
•
Check the system for leaks. If there are turn off the feed water flow and repair. Repeat above
process until all leaks are repaired.
A note on recovery rates
Your BlackMaxx™ RB8 is designed to operate at a recovery rate (percentage of product water to
total water used) at maximum of 70% for feed water of <1000 TDS, and 40-66% for feed water with
TDS ranging from 1000 to 2000.
DO NOT ATTEMPT TO OPERATE THE SYSTEM AT HIGHER
RECOVERY RATES UNLESS APPROVED BY FACTORY, AS THIS WILL CAUSE PREMATURE
MEMBRANE FAILURE OR INTERNAL SCALING AND EQUIPMENT FAILURE.
You may wish to operate your system at lower recovery rates where your dealer has identified water
conditions that may stress your membrane or where recommended pre-treatment feed water
