Installation

Unpack and verify all components are present and undamaged. Install in a clean, dry, and accessible location with adequate drainage.

Mount the unit: Secure the main housing to a stable wall or frame using provided brackets.
Connect water supply: Attach the inlet line (3/4" standard) to the main water source using the included fittings. Ensure the supply valve is closed.
Connect product water line: Attach the 1/2" outlet tubing to the purified water distribution point.
Connect drain line: Route the 1/2" drain tubing to a suitable floor drain or waste receptacle.
Electrical connection: Connect the power cable to the terminal block (L, N, PE) as per local electrical codes. Ensure power is OFF.

WARNING! System is heavy; use appropriate lifting equipment or multiple personnel. Ensure all plumbing connections are pressure-tight before operation.

First-Time Setup

After installation, power on the system and follow the initialization sequence on the digital display.

System priming: Open the main supply valve slowly. The display will guide you through the automatic priming and air purge process.
Initial calibration: Use the SETUP menu to calibrate sensors (TDS, pH) using provided calibration solutions.
Program operating parameters: Set desired flow rate, backwash frequency (default: every 72 hours), and alarm thresholds.
Connect to network (optional): Configure the remote monitoring port with IP address or device ID for system integration.
Run diagnostic test: Initiate a full system test from the MAINTENANCE menu to verify all stages and sensors.

CAUTION! Do not bypass the priming sequence. Ensure the drain line is unobstructed during initial startup.

Connecting Peripheral Devices

Remote Monitoring: Use Ethernet cable to connect to LAN, or RS-485 for daisy-chaining multiple units. External Alarm: Dry contact output terminals for connection to building alarm panels.

Turn OFF main power before making any electrical connections.
For network connection, configure a static IP or obtain DHCP address via the NETWORK menu.
For RS-485, ensure proper termination (120-ohm resistor at the last device) and unique device IDs.
Test communication using provided configuration software on a connected PC.

Tip: Label all cables during installation for easier future maintenance.

Operating Procedures

Normal operation is fully automated once configured.

Startup: Press POWER. The system will perform a self-check and begin water production if all conditions are met.
Monitoring: Check STATUS screen for TDS, pH, and flow rate. Ensure values are within acceptable ranges (TDS < 50 ppm recommended).
Manual Flush: Press MANUAL FLUSH button to initiate a 2-minute membrane flush. Useful after periods of inactivity.
Backwash Cycle: Occurs automatically per schedule. The display will indicate "BACKWASH IN PROGRESS". Do not interrupt.
Shutdown: Press POWER to enter standby. For extended shutdown, close the main inlet valve and run a manual flush first.
Data Export: Connect a USB drive to the service port (under cover) and use the LOGS menu to export history files.

WARNING! Do not open filter housings while the system is pressurized. Always shut off water supply and relieve pressure first.

Safety & Protection Features

Leak Detection: Sensors at base trigger automatic shut-off and audible alarm. High/Low Pressure Cut-off: Shuts down pump if inlet pressure is outside safe operating range. UV Fail Protection: System halts if UV lamp intensity falls below effective level. Filter Life Monitoring: Alerts when filter cartridges require replacement based on runtime or water volume.

Maintenance & Cleaning

Disconnect power and water supply before any maintenance.

Daily: Wipe control panel and housing with a dry, soft cloth.
Weekly: Inspect for leaks, check drain line is clear.
Monthly: Clean external sensor probes (TDS, pH) with distilled water and soft brush.
As Needed: Replace filter cartridges as indicated by the system alarms or per schedule (typically 6-12 months). Sanitize system using approved procedure in MAINTENANCE menu after filter changes.

CAUTION! Use only Vekooto-approved replacement filters and parts. Do not use chemical cleaners on the housing or sensors.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No Power / Display Dark	Power cord, circuit breaker, internal fuse	Check power outlet, reset breaker, verify main power switch is ON. Replace fuse F1 (5A) if accessible.
Low Water Flow / Pressure	Clogged pre-filters, closed valve, low inlet pressure	Check and replace sediment/carbon pre-filters. Ensure all valves are fully open. Verify supply pressure >30 PSI.
High TDS Alarm	RO membrane failure, sensor error, improper calibration	Run membrane diagnostic test. Recalibrate TDS sensor. Replace RO membrane if rejection rate <90%.
Continuous Beeping / Alarm	Leak detected, filter life expired, sensor fault	Check for water under unit. Acknowledge alarm via ALARM RESET. Check MAINTENANCE menu for specific error code.
System Won't Start (Pump not running)	Low pressure cut-off, air lock, pump fault	Ensure inlet pressure >30 PSI. Purge air from pump by briefly opening manual bypass (see service manual).
Remote Monitoring Not Connected	Network cable, IP settings, firewall	Check Ethernet cable connection. Verify IP address in NETWORK menu. Ensure port 502 (Modbus TCP) is open on network.

Factory Reset: MAINTENANCE menu > System > Reset to Factory Defaults (requires access code).
