Operation procedures
81050 Mini Hobby RO
Read user manual completely before using your reverse osmosis.
Wash procedure
1) Replace filter cartridge by a unit that will be only dedicated to wash procedure.
2) Insert concentrate and permeate hoses in a 5 US gallons bucket.
3) Fill bucket with permeate ideally heated at 40oC and add the necessary amount of soap. Follow manufacturer
recommendation.
4) Start RO (See step 8 of concentration cycle).
5) Leave RO running for 30 minutes.
6) Stop RO and rinse.
7)
Concentration procedure
1) Close all drain valves from V2 to V4.
2) Install strainer housing at pressure feed pump inlet.
3) Install prefilter housing. It is recommended to use a fresh cartridge for maple sap process. Tighten drain cap under filter
housing.
4) Open wide concentration control valve V1.
5) Connect RO to 110 power outlet.
6) Insert blue suction line into maple sap tank.
7) Insert permeate and concentrate hose in their respective tanks.
8) Start reverse osmosis with the interruptor. Verify if water goes to the pump after few seconds, if not, stop the pump.
9) Gradually close V1 concentration valve until complete closure of the valve. Take a minimum of 10 seconds for closing the
valve to gradually increase pressure in the system. Closing too fast could damage the system.
10) Periodically monitor operating parameters.
11) Once concentration process is final, gradually lower pressure by opening concentration valve and stop reverse osmosis.
*Warning, it is not recommended to run RO until sap runs out. Feed pumps may be damaged when running dry
*concentration of maple sap at higher level than 8 brix is not recommended.
Unsugaring procedure
1) Insert RO feed and permeate hose in the permeate tank, concentrate hose remains in the concentrate tank.
2) Start RO to begin unsugaring of the system (See step 8 of concentration cycle).
3) Take concentrate samples at regular intervals until sugar concentration is at 0.5 brix.
4) Stop RO
Rinsing procedure
1) Insert RO feed hose in permeate tank. Insert permeate and concentrate hose to drain.
2) Start RO (See step 8 of concentration cycle). A minimum of 80 gal US/300L of filtrate must be use.
3) Stop the RO when minimum water quantity has been used.

Operating cycles
Shutdown procedure
1) Loosen drain cap from filter housing. Remove filter cartridge from housing.
2) Open all drain and concentration valves from V1 to V4.
3) Disconnect suction hose and drain water out of it.
4) Unfasten and drain strainer housing at pressure pump inlet. Leave it off.
5) Start RO for 2 seconds. This operation will allow to flush residual water from the pump.
6) Repeat step 5 twice at 10 seconds intervals.
7) Disconnect electrical plug.
