Hello!
ROTEK KSRO Series RO systems are specifically designed for commercial and industrial-sized RO
systems.
It is designed with a fixed recovery rate of 60-65% by using ROTEK extra-large flow RO membranes
that can produce 4000~6000GPD (650~1000LPH) of permeate water flow, which means it can
produce more pure water at less cost.

READ THIS FIRST
Please pay attention to the following installation and safety recommendations:
Read the installation manual before installing this system.
NOTE! Please make sure your installation location has enough room and access to a 220v power supply.
Incoming Water
Incoming water pressure must be between 10 PSI and 100 PSI. Test your water occasionally to make
sure the system is performing. If your water is microbiologically unsafe or of unknown quality do not
use this system without adequate disinfection before or after the system. Extremely hot or cold
incoming water will damage the system and cannot be used. Your Untreated Water Inflow quality will
determine your needs for pretreatment and filtration.
Leaks
Inspect all connections after the installation to make sure no leaks occur, wait until after the system is
pressurized to inspect again. Check the system occasionally after installation or maintenance to make
sure no leaks have developed. Install the system in a location with adequate drainage.
General
This KSRO System is for climate-controlled indoor use only. Exposure to overly high or low-temperature
ranges will damage the unit. Follow all of your state and local laws and codes regarding plumbing even
if they differ from what is stated in this manual. If your state law requires it or you prefer to we
recommend using a professionally licensed installer or plumber who meets the requirements of this
system. All O-Rings, fittings, filter canisters, and Teflon tape wear out after a certain period. The lifetime
of your components is subject to change with the quality of the water supplied. Do not handle an
unwrapped filter directly with your bare hands as this can cause early filter failure. Use appropriate eye
protection when performing any drilling.
Maintenance
The owner/user is obligated to properly inspect and maintain the KSRO System when necessary, at least
every 1 year. This includes the following:
The O-Ring on the filter housing, membrane vessel, booster pump, solenoid valve diaphragm, and
fittings.
Replace any connectors and filter housings with proper replacement parts.
Sanitize your system as often as needed (this changes with the profile of your area’s incoming water).
Always use proper replacement filter cartridges with the correct size and length replacements.
Replace the Teflon Tape on all threaded connections and fittings.

▋Introduction
You have purchased the finest KSRO System available for your water purification. When properly
maintained this system will provide you with years of great tasting pure drinking water and trouble-
free service.
Please read the manual section regarding the proper care and maintenance of your KSRO System
before proceeding with your installation. Also, please make sure to inspect the package for any
missing components or shipping damages.
Simply read through the manual and complete the steps in order and you’ll have your system up
and running in no time. If you find any issues or have questions please contact your local distributor
or visit www.rotekwater.com for filter replacements.
System Specifications
* KSRO system recovery rate is calculated based on the volume of flush water discharged.
Recovery Rate = (Permeate Flow / Permeate Flow + Discharged Flush Flow)
* Permeate Flow Rate is calculated based on Rotek XL-4040 membranes. It is also possible to use
other brands of membranes with KSRO units, but the flow rate may vary.

Raw Water (Feed Water) Requirements
Raw water quality, pressures, and flow rates have a significant impact on the performance of any
reverse osmosis system. To ensure reliable and consistent long-term performance, it is important to
supply feed water having the minimum specifications detailed below. If your raw water supply is
marginal, you should consider using a raw water break tank and booster pump to supply the system.
KSRO Raw Water Specifications (minimum)
Hardness
< 5 ppm
Hydrogen Sulphide
0 ppm
Free Chlorine

▋Pretreatment Suggestion
Please make sure that the quality of your raw water meets the aforementioned KSRO raw water
requirements, otherwise, it is recommended to install pre-treatment equipment. You can install it by
yourself, or suggest using ROTEK’s existing standard pretreatment module, of course, it can also be
customized according to your raw water conditions.
KSRO Pretreatment Unit *Optional
1
20" filter housing x 1pcs, 5μm GAC filter cartridge
2
20" filter housing x 1pcs, 5μm CTO filter cartridge
3

▋Installation Notes
▲WARNING▲
All electrical work should be performed by a licensed electrician in compliance with all relevant
electrical safety regulations.
All piping works shall be performed by licensed plumbers and comply with relevant water
supply and drainage piping regulations.
Installation Notes
Before installation, ensure that the power supply matches the power requirements of the system.
Most units are supplied as standard for 220-240VAC 50Hz single phase operation.
1. Ensure that all plumbing connections for the feed water inlet, permeate and membrane flush
outlets are secure and conform to relevant plumbing regulations.
2. Ensure that power lead is rated to carry the current draw of the system. A minimum electrical
wire diameter of 3.5mm is recommended.
3. The external storage tank level contact switch should be connected to the blue wires labelled
for tank connection and located inside the electrical cabinet. Do not apply power to these
wires as the connection is designed for a simple non-powered contact type closure switch only.
4. Use an external pressure booster pump if the feedwater pressure is below 35psi.
5. If your feedwater supply is marginal, use a feedwater storage tank and booster pump to supply
the RO system.
Tools Required
Before you begin please make sure you have all of the following tools ready to use:
Box Cutter / Tube Cutter
Phillips-Head Screwdriver
Power Drill : 3/8” Drill Bit (for Drain Saddle)
