PRO SERIES
Portable Reverse Osmosis
OPERATORS MANUAL
WARNINGS
1. DO NOT stop the flow of waste water. Reverse Osmosis systems create waste
water in the process of making RO water.
2. DO NOT let the pump run dry. Line pressure water must be supplied to the
system before and during operation.
3.
OPERATING INSTRUCTIONS
1. The system may be operated in the horizontal position as shown above, or in the
vertical position. It is recommended to operate in the horizontal position to avoid
a tipping hazard.
2. CONNECT your water supply vis a garden hose. Supply should be minimum of 5
gallons per minute and have positive pressure.
3. CONNECT a short garden hose to the waste port to carry waste water away from
where you are operating the system.
4. CONNECT the hose you will be using for clean RO water.
5. SLOWLY turn on the water source.
6. FLUSH the system for 5 minutes before use. There should be water coming from
both the waste hose and the RO hose.
7. PLUG the power cord into a GFI 115 volt electrical outlet.
8. START the system with the switch on the pump motor.
9. The system is equipped with a flow restrictor on the waste stream. This limits the
waste to approximately 2.5 gallons per minute and applies appropriate back

pressure on the membranes to produce RO water. The system should yield 40-
50% recovery which is appropriate for this system. Actual water production will
depend on the feed water flow and pressure, temperature, and pre-filter
condition.
10. The system should not be operated using a self-closing hose handle or spray
nozzle. If the flow of RO water is stopped, the system is built with a safety blow-off
valve that will divert RO water to the waste stream. It is okay to use a spray nozzle
that does not stop the flow of RO water.
REMINDER –The PRO Series is not a high pressure washer.
When you are finished using the system,
11. TURN off the system with the switch on the pump motor.
12. FLUSH the system for 2 minutes.
13. TURN off the water source.
14. UNPLUG the power cord.
15. DISCONNECT all three hoses.
16. PLACE the system in the vertical position as shown below.
17. ALLOW excess water to drain from the system for a moment.

MAINTENANCE
1. VISUALLY check the sediment cartridge.
a. If it appears dirty, or the production of RO water diminishes, the cartridge
may need to be changed.
b. Order the Pleated Filter Cartridge, 2-3/4” x 9-3/4” 5 micron at
www.skwatermakers.net
2. ESTIMATE gallons used to determine when to change the carbon cartridge.
a. Typical city water supply is approximately 5 gallons per minute or 300
gallons per hour. The carbon cartridge capacity is approximately 5,000
gallons. Change carbon cartridge after every 16 hours of use (5,000
gallons capacity divided by 300 gallons per hour)
b. DO NOT operate the system without a carbon cartridge in place. City
water contains chlorine which can damage the membranes. Carbon
filters remove harmful chlorine.
c. Order the Carbon Block Cartridge at www.skwatermakers.net
3. MEMBRANES
a. Under normal operating conditions, the membranes should last 3-5 years,
depending on frequency of use, storage conditions, water conditions, and
temperature.
b. NEVER let the system freeze. In winter months, store the system in a
heated environment, or remove the membranes and store them sealed in
plastic in a heated environment.
c. SK Watermakers recommends a trained service technician remove or
replace the membranes in the system. If you want to perform this work
yourself, please see the video on the SKWatermakers channel on
YouTube –Changing a Membrane with Darryl.
d. Order membranes by calling SK Watermakers 941-257-2036
