Press and hold the “SET” button for 2 second and wait for a “beep” two times. If you do not confirm the
settings by holding down the Setup Button for 2 seconds, the settings will not be confirmed and they will
stay the same.
The time alteration procedure is identical for filters 2,3,4,5 as above
(e) Automatic Reminder Instructions:
When the system is alarming for a filter change, the filter replacement light will begin to flash and the alarm
will sound. Each time water production starts, the alarm will sound for 1:30 minutes. This will occur every
time until the filter reminder has been reset.
When the filters have been replaced, hold down the “ZERO” Button for two seconds until you hear 2 beeps.
The filter replacement light will shut off and the timer will reset.
NOTE: When you replace the new RO membranes, the TDS value may be higher than the alarm setting.
This is due to the chemical preservatives inside the membrane. After adequate flushing, this sanitiser will
be removed and the TDS will stabilise to normal levels. Due to this, the Micro-Computer alarm has a 4-day
delay. If the TDS has not stabilised after 4 days, please contact the manufacturer.
II. Commissioning
NOTE: New filtration systems will require a pre-flush before being used. The GT1-98 system will need to
run for at least 15 – 20 minutes before first use to clear and residue or fines from the filters.
•
Use a TDS meter to monitor the water to determine when the system is suitable for the intended
application.
•
When the system is connected correctly, turn on the incoming water supply and allow the first filter
cartridge to fill with water. Once this has stabilised, turn on the power to the system.
•
Turning the power on will actuate the inlet solenoid valve and the water will then begin to pass
through the remaining 2 pre-filters then to the membranes.
o
The pumps will turn on at this point – the working pressure gauge will remain at 0 until the
water reaches the membranes.
•
Once the water reaches the membranes, the drain line should begin to sputter and produce water –
it is normal for this to be cloudy and discoloured on first use.
•
At this point, the water will then need to slowly pass through the membranes and post filter so the
system will need to run for several minutes until water will begin to flow.
Your water is now suitable for use.
III. General Operation
The rating of this Reverse Osmosis system is 800GPD as per the membrane specifications meaning this
system is capable of approx. 2L/Min of water production, this will vary depending on water quality and a
number of factors. The systems are designed to be run in a closed loop configuration where the system
runs off a float switch or timer, this type of configuration allows for system downtime and helps extend the
lifespan of the pump as the system is intermittently producing water
When the system is installed in an open loop configuration and the pumps haven’t been allowed any
downtime you may expect to see a decrease in the pumps lifespan. If you intend to use the system this way
please contact us as we may have a better solution for your specific circumstance
Production scenario for closed loop configuration – The system is run for up to 8hrs a day with a 30 min
cool down period, in this configuration the system will produce approx. 1000L +/- per day. This is the
recommended runtime scenario specified by the manufacturer for extended pump lifespan
Production scenario for open loop configuration – The system is run for continuously without a cool down
period, in this configuration the system will produce approx. 3000L +/- per day. This is the maximum
capacity of what this system can produce however this may also decrease pump lifespan*
*Note: the pumps come with a 90-day replacement guarantee/12-month pro-rata warranty per pump from
date of invoice. If the pump fails within the first 90 days of operation, we will replace it, if it fails from 90-365
