Page 4: Introduction
INTRODUCTION Thank you for choosing our Nano RO 2- or 3-membrane system. Please read this manual carefully before installation and start-up. The CDL 2- or 3-membrane Nano RO is a simple and effective tool for maple and birch sap concentration. Its three-stage prefiltration removes impurities like suspended solids and larger organic matter to better protect membranes and improve overall system performance. Remarks and instructions 1. Read the instructions before installing and operating the RO system. -

tube on the recirculation circuit and 1/4” red on the concentrate outlet). • Stage 5: A regulating valve on the 1/4” concentrate outlet (red tube) increases and reduces the pressure and controls the level of concentration. Maximum operating pressure: 100 psi (70 psi on 2-membrane system). Recirculation pump: The 3-membrane Nano RO is equipped with a unique recirculation pump for better performance. By creating more cross flow on the membrane surface, the permeate flow remains steady and the system achieves higher concentration. CDL Sugaring Equipment... -

Page 17: How To Replace Filtration Cartridges
HOW TO REPLACE FILTRATION CARTRIDGES 1. Unscrew the cartridge housing. 2. Remove the old cartridge. 3. Insert the new cartridge into the housing. 4. Lubricate the transparent gasket lightly with silicone grease. Make sure the gasket is still in place. 5. Make sure that the cartridge is centred in the housing. Screw the housing into place. HOW TO INSTALL MEMBRANES 1. Unscrew the cover from the housing. 2. Remove the old membrane. 3. Lightly lubricate all O-rings and casing seals with silicone-based food-grade grease. Insert the new membrane fully into the housing. 4. Make sure the membrane seal is on the cover side. 5. Screw the cover onto the housing. CDL Sugaring Equipment... -

into the wash solution bucket. • Open the concentrate control valve. • Run the equipment in a closed loop into the wash solution bucket for 30 minutes. • Once the wash is finished, flush the solution to drain. • Repeat the wash if the wash solution is coloured or cloudy. • Rinse the equipment with no less than 10 to 15 gallons of clean permeate PROTECT FROM FREEZING • Protect the equipment from freezing during temporary storage. • If the equipment must remain in a cold place, remove the filters and drain the equipment properly. Reinstall filter housing and run the pump dry for a few minutes. This will partially remove water from the system and prevent frost damage to the pumps and other parts. • Make sure there is no water remaining in the equipment and lines. • The equipment may need to be thawed with warm water when it’s ready to be used again. • Make sure that all pumps are ice-free before using the equipment. Small pieces of ice may damage the pumps. Thaw the pumps with a hair dryer or by pouring warm water over them. IMPORTANT NOTES • It is always best to keep the equipment in an area that is above freezing temperature. • If the equipment is moved through freezing weather, make sure it is drained properly before exposing it to cold temperature.

Page 19: Long-Term Storage Procedure
R un the equipment in a closed loop for 1 hour or more, allow soaking overnight. If the water is cloudy, wash the system with CDL Super Flow Green, then rinse. 4. Storage solution Y ou may leave membranes in the unit for storage as long the unit is protected from frost. Citric acid is a good preservative that prevents bacteria from developing in the system. Add 1/4 cup of CDL citric acid to a 5-gallon bucket of permeate, then run the RO in a closed loop for ½ hour to allow proper mixing. To prevent leaks, disconnect the suction (yellow concentrate (red ), and permeate (blue ) tubes and insert the provided plugs in the ... -
