Warranty Evaluation Test Conditions: : Permeate flow rates and salt rejection based on the following test conditions: 550 ppm, filtered and dechlorinated municipal tap water, 77°F/25°C, 15% recovery, 7.0 pH and the specified operating pressure for membrane element type. Data taken after 60 minutes of operation.

A. Low temperatures and feedwater quality, such as high TDS levels will significantly affect the systems production capabilities and performance. Computer projections must be run for individual applications which do not meet or exceed minimum and maximum operating limits for such conditions.
B. Product flow and maximum recovery rates are based on feedwater conditions as stated above. Do not exceed recommended permeate flow.
C. Does not include operating space requirements.

OPERATING LIMITS D

Maximum Feed Temperature (°F / °C) 85 / 29 Maximum Free Chlorine (ppm) 0
Maximum Feed Temperature (°F / °C) 40 / 4 Maximum TDS (ppm) 2000
Maximum Ambient Temperature (°F / °C) 120 / 49 Maximum Hardness (gpg) 0
Minimum Ambient Temperature (°F / °C) 40 / 4 Maximum pH (continuous) 11
Maximum Feed Pressure (psi / bar) 85 / 6 Minimum pH (continuous) 2
Minimum Feed Pressure (psi / bar) 45 / 3 Maximum pH (cleaning 30 minutes) 2
Maximum Operating Pressure (psi / bar) 200 / 14 Maximum pH (cleaning 30 minutes) 1
Maximum Feed Silt Density Index (SDI) < 3 Maximum Turbidity (NTU) 1

D. System pressure is variable due to water conditions. Permeate flow will increase at a higher temperature and will decrease at a lower temperature.
