Warranty Summary
APEC WATER ROES-50 has a limited product warranty of one (1) year from the date of purchase covering defects in materials and workmanship.
The APEC Water ROES-50 is a reverse osmosis system designed for home use. Operation involves the following key stages:
- Feed Water Connection: Connect the system to your cold water supply.
- Filtration Process: Water passes through multiple stages of filtration including sediment, carbon block pre-filters, and a reverse osmosis membrane to remove impurities.
- Storage Tank: Purified water is stored in a tank until needed.
- Dispensing: Dispense purified water through a dedicated faucet.
- Maintenance: Regular filter changes are required to maintain system performance.
Troubleshooting and error codes
| Problem | Possible Causes and Solutions |
|---|---|
| Air Bubbles: Lots of Air bubbles in cup or bottle when filling | Normal after initial installation or filter replacement. System will self-purge air. Drain 1-2 tanks of water. |
| No Water at Dispensing Faucet | Water supply off, tank valve closed, output line crimped, incorrect installation, low tank pre-charge pressure, ASO connection error. |
| Sluggish Flow At Dispensing Faucet | Insufficient water pressure, input water to RO blocked, tank not filled yet, low tank pre-charge pressure. |
| Tank Takes Long Time To Fill (does not meet claimed GPD) | Insufficient water pressure, low water temperature. |
| Filter Housing Is Leaking | O-ring needs replacement or is not seated correctly. |
| TDS (Total Dissolved Solids) Level Reads Higher Than Normal | Forgot to insert membrane, membrane inserted incorrectly, water pressure too low, input source water very high TDS, drain water flow restricted, fluctuating input water TDS. |
| There is a leak at the Tank ball valve connection | Insufficient Teflon tape applied during installation. |
| System Slow Shut-Off: Drain water runs for hours (6-7 hrs) - but Eventually Stops | Insufficient input water pressure, feed water valve partially blocked, pre-filters partially clogged, RO busy feeding multiple output points. |
| System Does Not Shut-Off: Drain water runs all day - and Never Stops | Input pressure way too low. |
| RO Makes Humming Noise | Air bubbles trapped in the Check Valve. |
