gauge reads about 60 psi (4.1 bar). Now, by opening the tank inlet valve the tank pressure should
begin to drop and the system should turn on when the pressure drops below about 40 psi (2.8
bar). If the system fails to shut off at 60 psi (4.1 bar), watch the gauge and be sure that it does
not rise above 80 psi (5.5 bar). If it reaches 80 psi (5.5 bar), unplug the system. Refer to §7.1.2
for TANK PRESSURE SWITCH ADJUSTMENT.
§6.0 OPERATION AND MAINTENANCE
Nimbus MN-800-TF systems are designed for simple operation with little user intervention.
Nimbus recommends keeping accurate performance records and following a regular preventative
maintenance schedule to maximize the life of your system. A performance record sheet is
provided at the back of this manual for you to copy and keep near your system. This record sheet
will be important for warranty verification, trouble shooting as well as possibly suggesting more or
different pre-treatment.
§6.1 DAILY SYSTEM CHECKS
Your water supply pressure can vary from time to time. This can also affect your system
operating pressure. Therefore, it is recommended to check and adjust your system pressure daily
to ensure maximum water production rates and quality. Check both the water supply pressure
gauge and the filter pressure gauge. Under normal conditions, there should be a 3-5 psi
difference between the two gauges. When the difference reaches 10 psi, a pre-filter change is
recommended. See §7.4 PRE FILTER CARBON CARTRIDGE REPLACEMENT for further
discussion.
§6.2 MONTHLY SYSTEM CHECKS
In addition to the daily checks the procedures in §5.2 PERFORMANCE VERIFICATION may be
performed, record all data on your performance record sheet.
§6.3 QUARTERLY SERVICE
It is recommended to change both sediment and carbon filter cartridges at least every 3 months.
Carbon cartridges should be changed more often if bad taste and/or odor become evident. The
pre-filter carbon cartridge should be changed more often if water supply pressure and filter
pressure gauges differ by 10 psi or more, or if the Chlorine content of the city water is higher than
0.2 ppm.
§6.4 PERIPHERAL EQUIPMENT
Peripheral equipment such as pre-filters, post-filters and tanks also have periodic maintenance
requirements. It is essential to maintain these as they can have a dramatic effect on the
performance of your system. Refer to their specific manuals for proper maintenance procedures.

§7.1 LOW PRESSURE SWITCH ADJUSTMENT
•
The low pressure switch is factory set to turn the system off if feed pressure drops below
12 psi (0.8 bar). This switch can be adjusted to as low as 3 psi (0.2 bar) and as high as 20
