Chapter 6 Maintenance
6.1 Routine maintenance
Maintenance of the ultra-pure water system is simple and convenient despite its
integration of sophisticated equipment which combines water process, computer-control and
precision instruments to monitor.
Keep feed water going smoothly.
Please stop main unit when feed water is cut off so that you can avoid large numbers
of impurities in the water flowing into the apparatus, it will decrease the life time of
pre-treatment cartridge.
Constantly pay attention to water quality of the feed water. you had better stop the
main unit immediately When feed water is of poor quality (yellow, high turbidity,
conductivity than 400us/cm, with the smell). If necessary, you can purchase another
enhanced pre-treatment. (Recommend that you can purchase TDS pen to measure
water quality regularly)
This main unit is controlled by computer and monitored by precision instruments, an
equipment of high-precision, so if the local voltage is not very stable, please install
one 500W manostat and with good ground connection.
Keep both indoor environment and the instrument surface clean.
If you need to stop main unit for a period, please keep in mind that firstly you should
press “flush” keypad to flush the Smart-Mini system , then have the inlet valve
closed and power off.
Regularly disinfect and clean the water tank. If there are some special requirements,
please install UV disinfector and air filter.
6.2 Periodic maintenance
Please refer to the following maintenance periodic table. Timely maintain this
SMART-MINI system to enable it to keep in good condition.
Twice each year/ replace it if necessary when the
amount of water is on the decline
The amount of water is reduced or a mention of
Pure-water conductivity dropped/make pure water rate
