Initial Startup
1. Open the feed water supply valve.
2. Direct the product water tubing to drain.
3. Open the recirculation valve (HCV-1) fully counterclockwise, then close two turns.
4. Connect the system to the power supply. Turn the power switch to the ON position.
NOTE If the inlet pressure falls below 20 psi during operation, a booster pump will be necessary.
CAUTION! If the pump chatters loudly, it is starving for water (cavitating). Turn the unit OFF
immediately to prevent pump damage. Correct the low pressure condition before
proceeding.
5. Check for leaks at all tube fittings and threaded joints.
6. Set the inlet pressure regulator (installed ahead of the Pre-filter) to 10 psig (69 kPa) below the minimum read-
ing shown on the inlet pressure gauge, but no lower than 20 psig. This will allow for pressure variations in the
feed water.
7. Slowly close the recirculation valve until the desired (normalized) product flow rate is attained. Check again for
leaks.
8. Allow the unit to run so that the shipping solution (sodium bisulfite and glycerin) is flushed from the system. Test
the concentrate water for sulfite; continue flushing until no sulfite is detected.
CAUTION! As the concentrate flow is reduced, the system pressure will increase. Open the sys-
tem pressure control valve as required to prevent the system pressure from exceeding
150 psi (1553 kPa). Excessive pressure will damage the system.
NOTICE
Depending on the feed water quality, it may be possible to operate the unit with a lower concen-
trate flow rate, which would decrease operating costs. Refer to the printout from the Culligan®
CAAP® (Computer Aided Application Program) software, which indicates maximum allowable
recovery. If a printout is not available, contact the Culligan dealer.
9. Measure the product flow. Adjust the feed pressure with the system pressure control valve until the product
flow is approximately 10% higher than the flow required for the application.
CAUTION! DO NOT exceed 150 psi (1553 kPA) or the pump may be damaged. The fittings and tub-
ing may also fail and may cause property damage.
NOTICE
By adjusting the feed pressure as low as possible to meet the application requirement, the service
life of the pump and RO elements will be optimized. The system should run continuously, rather
than go through frequent start/stop cycles. Do not exceed specified product flow rate!
