days, we will cover it on a pro-rata basis. The pumps as well as the filters are classed as a consumable
item
IV. Automation
The system is fitted with high and low-pressure switches. This will allow the system to know when to shut
off due to the tank being full, or the feed water has been shut off.
When power and water is connected to the system and the outlet is open, the system will automatically
produce water. When the outlet shuts off, the high-pressure switch will trip after a period of time (similar to
a household pump) and then the system will shut down. When the outlet is opened and the pressure falls
below the limit, the system will start up again.
Similarly, when the feed water is cut off to the system, the low-pressure switch will trip and the system will
shut off after a few seconds.
If installing this system to a float switch in a tank, you will need to disconnect the high-pressure switch and
connect the float valve terminals in its place. This will then run the shut off based on the float rather than
the pressure.
TIP: If the system needs to be shut down and serviced, a handy tip is to shut off the inlet water supply and
allow the pressure to bleed out (few seconds) before shutting off the power. This will make it much easier to
disconnect any fittings.
Maintenance
I. Replacement Parts
A list of replacement parts is listed below with their corresponding recommended lifespan for replacement.
II. Replacement Cartridges
On Municipal water supplied, the pre-filters should be changed every 45,000L (720 Hours constant Run
Time) OR 6 Months, whichever occurs first.
Post Carbon Filter:
This filter should be changed every 5,000L or 6 Months, whichever occurs first.
DI Resin:
Due to the nature of resins and the variance of water quality, this media will also need to be monitored with
a TDS pen or meter to determine when the filter media has expired. DI resin will extract residual ions from
the water reducing the RO water back to a 0 TDS reading. The filter media will require changing once the
TDS exceeds your required limit. To change the DI media:
•
Inline DI Filter:
Disconnect the tubing from the inline filter and remove the filter from its mounting
clamps. Unscrew the end cap in an upright position and remove the sediment pad and o- ring to
avoid getting debris on the o-ring seal. Discard the filter media and rinse the cartridge with clean
water, removing and remaining DI resin. Refill the housing with resin, replace the pad and o-ring
and replace the head cap.
•
DI Cannister Filter:
Undo the housing cap and remove the DI cartridge. Unscrew the filter from the
bottom and discard the DI media. Rinse the housing and sediment pad with clean water removing
any of the remaining expired DI. Fill the cannister with 1Kg of DI media (Try not to compress it,
gently tap the cannister to allow the media to settle into position). Replace the sediment pas and
screw the cap back on.
