FILTER MAINTENANCE & CHANGE INSTRUCTIONS:
This recommendation is intended for maximum efficiency of RO water production by your system.
1,
Filter Maintenance
a, It is OK to put pre & post filters on the shelf for several years.
b, Keep the sealed, non-opened filter in an air tight container to prevent it from absorbing contaminants
from the air.
2,
Membrane Maintenance
a, The dry packed membrane usually has a two-year shelf life. To prolong the shelf life, we recommend
you keep the non-opened dry membrane in the refrigerator.
b, Once being used, we recommend you run the RO system every day, at least 10-15 minutes (about 1
gallon or 4 litres drinking water.) This helps to maintain the membrane performance.
c, If the RO system is not used for a few weeks, drain the storage tank. To bring the unit into service fill the
tank and drain it twice, and allow to refill. Your RO system will then be ready to reuse.
Your system is fitted with a membrane flush valve. The purpose of this valve is to flush impurities from
the membrane using a water flow higher that allowed by the flow restrictor. We suggest you open this
valve for 2-3 minutes every 6 –8 weeks. This will help to extend the membrane life.
3,
Filter & Membrane Change Procedures:
a, Shut off the water supply.
b, Turn off the tank ball valve by turning the handle through 90 degrees.
c, Open the tap fully for continuous flow.
d, Slide the housing wrench in (bowl spanner) over the filter bowl. Use one hand to hold the system and
the other hand to turn the wrench clockwise to separate the head from the bowl.
NOTE:
IF IT IS TOO TIGHT TO OPEN THE HOUSING YOU MAY TRY TO UNPLUG THE FITTING
BETWEEN THE RED TUBING AND THE SYSTEM IN ORDER TO REDUCE THE AIR AND WATER
PRESSURE INSIDE THE HOUSING.
e, To change the sediment cartridge and the pre-carbon cartridge you need to open the clear and opaque
housings, remove the used filters and put the new filters into the housings. Make sure the O-rings are in
place and smear a little Silicone grease on the O-rings. Replace the filter bowls and tighten by turning
the bowl anti-clockwise.
f, The
Carbon Post-Filter
and
remineraliser
must be installed the correct way, with the flow arrow
pointing in the direction of flow. Remove the existing cartridges by disconnecting from the threaded or
pushfit connectors.
Pull cartridge gently to remove from the holding brackets, discard used cartridge. Place new cartridge
over the holding brackets & push gently into place. Re-attach the threaded/speedfit connectors.
g, Turn on the water supply and make sure there are no leaks.
h, Let the water drip from the tap for about 10 minutes. If the water flow is less than 1 cup (8 oz or 240 ml)
per minute, it may be a signal to change the membrane.
i,
Membrane Change Procedure
:
Shut off water supply.
Unscrew the cap of the membrane housing using the wrench provided.
Slide out the used membrane & discard. (You may need thin nosed pliers to grip the membrane spigot.)
Insert the new membrane with the 2 O-rings into housing first with the black brine seal at the open end
of the membrane housing.
Be sure it is fully seated into bottom end.
Screw cap back on to the membrane housing, make sure O-ring is still in place.
Turn on water supply & check for leaks.
It may take 10-20 minutes for new membrane to run to normal flow.
Carry out system start up procedure.
