FEED WATER AND OPERATION SPECIFICATIONS
Nothing has a greater effect on a reverse osmosis system than the feed water quality. If your
system is altered at the site of operation or if the feed water conditions change, please contact
Hydrologic. Before starting the RO system, it is strongly suggested to obtain an up to date
water analysis of the water to be treated.
IT IS VERY IMPORTANT TO MEET THE MINIMUM FEED WATER AND
OPERATING REQUIREMENTS OUTLINED IN THIS MANUAL. FAILURE TO DO
SO WILL CAUSE DAMAGE OR FAILURE OF THE SYSTEM COMPONENTS
AND MEMBRANES. DAMAGE TO THE SYSTEM DUE TO OPERATION
OUTSIDE OF THE SPECIFICATIONS OUTLINED IN THIS MANUAL WILL VOID
THE MANUFACTURER’S WARRANTY. CHECK YOUR FEED WATER
CHEMISTRY AND, IF NECESSARY, CONSULT WITH HYDROLOGIC BEFORE
START UP OF THE SYSTEM.

†
Low temperatures and feedwater quality, such as high TDS levels will significantly affect the systems production capabilities and performance.
*If any of the feed water parameters are not within the given limits, consult HydroLogic for assistance.
HIGHER TDS AND/OR LOWER TEMPERATURES WILL REDUCE THE SYSTEM’S
PRODUCTION.
