Maintenance Guide - Reverse Osmosis Systems
INITIAL INSTALLATION
Follow the proper procedures for the set-up, installation and start-up of all systems. Problems (short and long-term) occur
when the systems are installed incorrectly. If any questions arise after installation, consult the trouble shooting guide for
assistance.
NOTE; ONCE INSTALLED CORRECTLY, THE MORE CONSISTENTLY THIS PRODUCT IS USED THE BETTER.
REPLACEMENT OF FILTERS, MEMBRANES, AND UV LAMPS (if applicable)
Follow the proper procedures for the shut-down of system, and the removal and replacement of the filters, membranes and/
or uv lamp (if applicable). Once a replacement procedure has been completed, the proper start-up of all systems is again
as important as it was when the system was first installed. If any questions arise after replacement procdures, consult the
trouble shooting guide for assistance.
Note: If the system was fine and only started having issues after the replacement of filters, membrane, and/or uv lamp,
than some procedure was not properly followed when re-starting the system.
MAINTENANCE
Reverse osmosis systems can be a sensitive product not applicable to other drinking water filtration systems because of
these various issues;
• Interconnection of system to a storage tank to store production water
• Interconnection of system to a drain line for draining rejection water
• Need for proper line pressure over the membrane for proper water quality and overall function
• Limits to the quantity of available water due to production rates over a day (divide by 24 provides
the RO production capacity over an hour) If you empty a tank it can take hours to refill before usage
• Interconnection to other devices, length of tubing for filtered water to travel and the potential for
warranty issues with other items due to the aggressive nature of RO water
MONTHLY
Empty Storage Tank
This is a little trick you won’t get from someone trying to sell you a service/maintenance agreement.
Empty water from and close any other devices connected to RO unit. Open and lock your dispenser in place in order to
empty storage tank completely of water. If you have a dispenser that does not lock open than hold open until tank has
been emptied. Wait until you see the water come to a very slow trickle or drip. Close dispenser and allow RO to manufac-
ture a completely new and fresh tank of water. Do this overnight to allow RO to produce enough water before you rise the
following day. Once tank is refilled than open other devices connected to RO. This procedure keeps the proper pressure on
the tank bladder and on the RSR control valve and allows better water flow, quality and quantity.
Check System
Visually check dispenser connections, system connections and drain. Be aware of any excessive household water
pressure or changes in your incoming water quality as well as changes in the production water.
YEARLY
Replacement of filters, filter cartridges, in-line filter cartridges, and uv lamp (if applicable).
Note: Replace, as needed, due to local water conditions and usage but do not exceed one year.
Membrane can be replaced as a convenience with all other filters on an annual basis (Purchased as a set for your
specific RO system). However, membrane may last between 18 months up to 3 years, based on local water conditions
and usage.
STORAGE OF UNIT OR PROLONGED PERIODS OF INACTIVITY, if applicable
Empty tank completely, shut off water supply to unit, remove filters and membrane and store in a cool dry location or
refrigerator.
Upon return, begin a disinfection procedure prior to any filter/membrane replacement, replace filters and membrane,
and begin start-up procedure as if it were a new unit.
