LONG TERM STORAGE / PRESERVATION PROCEDURE
During periods when the RO unit is to be shut down for an extended period of time, it is
necessary to re-flush the unit every three weeks OR to circulate a preservative solution
through the membrane to prevent the growth of biological organisms. Use the following
procedure to preserve the RO elements:
PRESERVATIVE CHEMICAL #3 IS A FOOD GRADE PRESERVATIVE. SEE WARNING
LABEL ON SIDE OF PACKAGE AND ADHERE TO ALL SAFETY PRECAUTIONS ON
LABEL.
NOTE: You should allow your unit’s product water to run to drain for the first 30
minutes after cleaning or upon start up after preservation.
The procedure is the same than cleaning Step 1 to Step 6. Step 7 is to remove the
cleaning filter and leave everything as it is until using the RO system again. Use either
Cartridge or powder for preservation. Use 3 TBS of powder.
OIL CHANGE PROCEDURE
An oil change is recommended after the first 100 hours of RO use. Subsequent oil changes
are to be performed every 500-hour intervals OR changed annually. Change oil any time
moisture is detected or if oil is cloudy. For additional pump information, refer to
MANUFACTURER’S LITERATURE
at the back of this manual. Or CAT Pumps CD.
NOTE: The first oil change requires a complete oil drain, to ensure your pump is free
of any fragments.
DO NOT RUN PUMP WITHOUT OIL IN THE CRANKCASE.
NOTE: Prior to the oil change, it MAY facilitate the oil replacement process by running
the RO unit to heat the oil. Heating the oil reduces the viscosity allowing it to be more
fluid to travel through the pump.
