14.0 Maintenance
There are four main areas of routine maintenance that must be attended to:
• Chlorinating system
• Filter cleaning
• Pump Screen Cleaning
• Tank cleaning
Chlorinating System
When left untreated, grey water can quickly turn to black water. The BRAC RGW System features
an automated programmable chlorinating system, which circulates the grey water in the holding
tanks through the chlorinator and back through the filter housings at pre-programmed intervals.
While the timer controlling this system is preset at the factory, proper chlorinating requires the user
to visually inspect the chlorinator for remaining tablets, and replace when necessary. This is most
conveniently done during the filter cleaning procedure. (See next section – “Filter Cleaning”).
The chlorinator is located in the upper portion of the tank and is visible when the lid is removed.
When the chlorine tablet supply is getting low, simply remove the threaded cap of the chlorinator by
turning counter-clockwise.
Warning:
Do not inhale the chlorine gas when removing the chlorinator lid as serious injury may occur!
Following the manufacturers Calcium Hypochlorite handling instructions, refill the chlorinator. The
chlorinator will hold eight (8) 140-gram (5oz.) tablets. Replace the chlorinator lid and tighten se-
curely. We recommend that the NORWECO brand “Bio Sanitizer” Calcium Hypochlorite disinfecting
tablets be used.
Some jurisdictions require that grey water be dyed blue or green before being served to toilet fix-
tures. In this case, contact your BRAC Systems representative for information on our BDD-30 Blue
Dye Dispensing Unit.
Filter Cleaning
As we are unable to determine the exact grey water inflow volumes for each application, we recom-
mend that you inspect and clean the filters every week. If you realize that the build up of residue in
the filters does not warrant cleaning the filters every week, we recommend that you decrease the
frequency of inspecting and cleaning of the filters by three days at a time, every ten days, every
thirteen days, every sixteen days and so on, until you determine the proper time interval for your
particular situation. (See figure 6 page 18)
Also bear in mind that the capture of laundry water will cause the filter to clog more frequently due to
laundry lint.
Procedure:
If the potable water bypass is installed, open the bypass valve to allow the toilets to operate on
1.
potable water during this procedure.
If the grey water bypass is installed, close the bypass valve to divert the grey water to the sewer
2.
during this procedure. If a grey water bypass has not been installed, do not use the bath, shower
or laundry while cleaning the filter.
