System Start-Up and Operation Procedures
Reverse Osmosis Systems have specific issues with air in system, proper pressure in tank,
the proper draining of reject water, and proper connection between various components.
Follow these procedures for new installations and all filter/membrane replacements.
If anything is discovered, this is the time to discover it and correct any problems or
questions that arise. Lack of a proper start-up will void the warranty.
Only For Units with Electrical Connection: Units with UV Option and/or Booster Pump Option
Step 1A:
Connect UV lamp cord and plug in transformer unit to typical 110v electric outlet.
Step 1B:
Connect Booster Pump cords and plug in transformer unit to typical 110v electric outlet.
NOTE:
Electrical outlet must be dedicated and unswitched. Be aware of any GFI outlets and
the need to reset. Surge supression highly recommended.
For All Units:
Step 2:
Close inlet water supply to the system.
Turn off water supply to other devices that may be connected to this unit.
Step 3:
Close storage tank valve. Storage tank valve should be closed. Tank valve handle is
perpendicular or at a 90º angle to the yellow tubing connected into the tank valve.
Step 4:
Pull up and lock dispenser/faucet handle in open position (if using another type of
dispenser - put into open position).
Step 5:
Turn on any main water supply which was shut off earlier (usually for new install).
Open inlet water supply to the system.
NOTE:
Initially you may observe a sputtering. It may take up to 10-15 minutes for water to begin
to drip from dispenser/faucet.
Step 6:
Once a steady drip is available (drips about a gallon of water per 1-11/2 hours),
Close the dispenser/faucet
Step 7:
Open storage tank valve, so that tank valve handle is parallel or inline with the yellow
tubing connected into the tank valve.
Step 8:
Allow system to fill the tank twice and drain both tanks of water produced before
actual use**. This will wash carbon fines, membrane preservatives, and air*** from the
system. This process may take in excess of 10 hours.
NOTE:
This correct procedure of "fill then empty, fill then empty, and final fill" may be a full day
or an overnight procedure. This is the proper way this type of system is started up.
Continue with the proper start-up of the reverse osmosis system
