Snapshot
The OptiPure® OP350/50 Water Treatment System utilizes 
reverse osmosis (RO) to remove >97% of the total dissolved 
solids (TDS) from water. Then a balance of minerals is 
dissolved into the RO water to provide desirable “Optimized” 
water TDS. The system operates at line pressure and can 
produce up to 350 gallons per day of optimal quality water 
for applications where TDS reduction or the removal of the 
majority of hardness minerals is required. The OP350/50 
is a complete system that includes integrated pre-filtration 
with particulate and chlorine reduction, reverse osmosis 
and mineral addition in a space saving, wall-mount or 
undercounter design. Adjustable Reject Flow Control 
allows precise adjustment of Product/Reject Ratio. A builtin full system bypass valve and sample port assures no 
service interruption and simplifies routine maintenance. 
Also included is a 50 gallon atmospheric storage tank with 
a top-mounted variable-flow repressurization system and a 
sub-micron air breather. Hose, tubing and fittings required 
for installation are included.
System Benefits
JOB NAME/NUMBER_____________________
• Virtually eliminates scale & corrosion problems related to 
high TDS & water hardness and reduce the potential for 
corrosion related to water chemistry.
• 
The integrated QTMA mineral addition cartridge adds 
desirable TDS to provide balanced, buffered Optimized 
water.
• 
High capacity parallel pre-filtration protects the RO 
membrane and assures consistent performance for up to 
one year between pre-filter replacements.
• Compact, Modular Design enables installation under 
counters and in very tight spaces.
• Maximize equipment operating and energy efficiency.
• Adjustable Reject Flow Control minimizes water use due 
to seasonal fluctuations in water temperature.
• Dual-read digital TDS meter provides push-button 
monitoring of membrane performance and optimized water 
quality.
• 
Sample Port allows quick and simple system checks and 
adjustments. 
• 
Built-in pressure gauge allows visual monitoring of 
operating pressure.
• Integrated system bypass valve eliminates down-time or 
service interruptions.
•
All consumables are easy-to-change Qwik-Twist 
cartridges.
• Simple, easy-to-service and maintain design.
Application
Any foodservice equipment where it is desirable to 
remove existing TDS (total dissolved solids) and 
provide a consistent balance of buffered TDS to 
minimize problems associated with high TDS, high 
hardness, high chlorides or any other TDS-related 
problems.
Installation Tips
Feed-water connection to system should be COLD only. 
Do not exceed system specifications for temperature 
  and pressure.
Provide a dedicated 1/2” water line to the unit for   
  consistent flow and pressure to the system.
Allow 3” clearance below system for filter cartridge  
  removal and replacement.
Connect filtered water line to steam production   
  connections only. Do not use for condenser water.
Detailed installation, operation & maintenance manual 
  is included with each system.
 Mount the OP350/50 where it can be easily serviced.

It is recommended that Pre-Filters and Mineral Addition 
Cartridge be changed every 6 months, when capacity 
is reached or when feedwater pressure or flow becomes 
inadequate. Membrane life varies depending on feedwater 
conditions and PreFilter maintenance. 12-18 months under 
typical conditions but it can be as long as 3-5 years.
