| Failure |
Probable cause |
Troubleshooting method |
| 1. The unit is not starting. The power button backlight and display do not illuminate. |
No power |
Check the utility outlet the unit is connected to and the integrity of the power cord |
| The fuse in the power connector is blown |
Replace the fuse (nominal of 2А) |
| Electrical circuit breakage or drive board defect |
Contact a service center for diagnosis and troubleshooting |
| 2. Short life of pre-treatment cartridges (CFC, MFC, ACC). Needs cartridge replacement more often than one time in three months. |
Improper level of suspended solids and iron in the source tap water (seasonal change in water quality, repair of water supply networks, corrosion of metal pipelines in the building, etc.) resulting in rapid contamination of the cartridges. |
Perform a daily visual inspection of the quality of the source tap water before the unit is put into operation. After water networks are down overnight or on weekends, rusty water may need to be discharged to reduce the load on the pre-treatment cartridges. |
| Estimate the quality of the tap water for meeting the unit data sheet requirements (turbidity, total iron). |
| Install extra stages of purification of raw water from suspended solids such as a mesh filter, a Aquaton MLS MINI deferrization filter with backwash. |
| 3. Short life of membrane element cartridges (ROC). Need for cartridge replacement more often than once a year due to poor performance of the membrane unit. |
Improper level of suspended solids and iron in the source tap water resulting in rapid contamination of the cartridges |
Estimate the quality of tap water for meeting the unit data sheet requirements (salt content, hardness). As may be required, install de-ironing and softening filters. |
| Fast contamination of the ROC cartridges due to untimely replacement of the pre-treatment cartridges (MFC, ACC). |
Replace the pre- treatment cartridges at the frequency shown in the data sheet. |
| Biological fouling of the cartridges and the flow-through part of the unit due to infrequent use of the unit and prolonged downtime. |
The recommended operation mode of the unit is continuous. Long downtime (more than 5 days) should be avoided. If there are signs of microbiological fouling (high TMC in the filtrate, bad odor of the filtrate) you should contact a service center for recommendations on decontamination of the flow part of the unit. Contaminated cartridges should be replaced. |
| 4. Short life of membrane element cartridges (ROC). Need for cartridge replacement more often than once a year due to high electric conductivity of the filtrate after the membrane unit. |
Degradation of the selective layer of reverse osmosis membrane in the ROC cartridges due to untimely replacement of the pretreatment cartridges (MFC, ACC). |
Replace the pre- treatment cartridges at the frequency shown in the data sheet |
| Displacement of the internal seals of the ROC cartridge or its holder. |
As a rule, this problem is characterized by a leap in the capacity of the membrane unit and the electrical conductivity of the permeate. To correct this, following actions are recommended:
- visually inspect all ROC cartridge holders for folded seals;
- detect a faulty cartridge by replacing each ROC cartridge with a new one, followed by checking the membrane unit for normal operation.
|
| 5. Short life of demineralization cartridges (MBC) |
High conductivity of permeate after ROC cartridges caused by failure of these cartridges |
See par. 4. |
| Transporting and storing MBC cartridges in improper conditions |
Transport and store MBC cartridges under the temperature conditions specified in the "Storage and lifespan of the consumable products" section |
| High conductivity of permeate after ROC cartridges, caused by changes in the source water quality |
An increase in the electrical conductivity of the source water leads to a proportional increase in the electrical conductivity of the permeate. Keep in check the electrical conductivity of the source water. |
