Overheat Protection	Prevents excessive temperatures in the system

Installation

Unpack and inspect all components. Installation must be performed by a qualified technician.

Mount the solar collector: Install on a south-facing roof or suitable ground location using provided hardware.
Position the storage tank: Place in a dry, indoor location near existing water heater connections.
Install the pump station: Mount near the tank, ensuring proper orientation.
Connect piping: Use insulated pipes for collector loop and domestic water connections.
Electrical connections: Connect controller and pump to power supply as per wiring diagram.
Fill and pressurize system: Fill heat transfer fluid loop and check for leaks.

WARNING! Roof work involves fall risk; use proper safety equipment. Ensure all connections are pressure-tight.

First-Time Setup

Power on the controller; follow initialization procedure.

System initialization: Controller will perform self-test and detect sensors.
Set language: In SETUP menu, select preferred language (default: ENGLISH).
Configure parameters: Set pump differential temperatures, frost protection, and overheat limits.
Test operation: Verify pump activation when collector is hotter than tank by set differential.
Check hot water output: Allow system to run and verify hot water at taps.

CAUTION! Do not bypass safety devices. Ensure system is properly grounded.

Specifications

Collector Type: Flat plate, selective surface.
Collector Area: 2.8 m² (approx.).
Storage Tank Capacity: 300 liters (approx. 80 gallons).
Maximum System Pressure: 6 bar.
Heat Transfer Fluid: Propylene glycol mixture (frost protected).
Controller: Digital display with temperature readouts and fault indicators.
Power Supply: 230V AC, 50Hz (or as per local standards).
Operating Temperature Range: -20°C to 120°C.
Certifications: CE marked, Solar Keymark certified.

Controls and Settings

Access settings via controller buttons and display.

Controller Display: Shows collector temperature (T1), tank temperature (T2), pump status, and error codes.

Buttons: MENU, UP, DOWN, ENTER, ESC.

Settings Menu: Differential ON (default 6°C), Differential OFF (default 3°C), Frost Protection set point, Overheat limit, Pump run time, Language, Time/Date. Status Indicators: Pump On LED, Error LED, Solar Gain indicator.

Connecting Components

Follow piping and wiring diagrams provided in installation manual.

Collector loop: Connect collector inlet/outlet to pump station with insulated copper pipes.
Storage tank: Connect heat exchanger ports to pump station.
Domestic water: Connect cold water inlet and hot water outlet to tank.
Sensors: Plug collector and tank sensors into controller.
Power: Connect controller to mains power and pump to controller output.

Tip: Use thread sealant on all threaded connections. Pressure test before filling.

Operation

System operates automatically once configured.

Normal operation: Controller compares temperatures. Pump runs when T1 > T2 by differential ON setting.
Pump stops when temperature difference falls below differential OFF setting.
Frost protection: Pump runs if collector temperature approaches freezing point.
Overheat protection: Pump runs or system dumps heat if tank temperature exceeds safe limit.
Monitoring: Check controller display for temperatures and status.

WARNING! Do not touch collector or pipes during operation; they can be extremely hot.

Maintenance

Annual maintenance recommended by a qualified technician.

Check heat transfer fluid level and concentration (every 2-3 years).
Inspect pipes and connections for leaks or corrosion.
Clean collector glass surface to maintain efficiency.
Check pump operation and controller settings.
Verify pressure in expansion vessel.
Test safety valve operation.

Care & Cleaning

Collector surface: Clean with water and soft cloth; avoid abrasive materials. Storage tank: Wipe exterior with damp cloth. Keep area around system clear of debris.

CAUTION! Do not use high-pressure water on collector. Do not walk on collector.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No hot water	Pump not running, low sun	Check pump power and fuse; verify sun on collector; check controller settings.
Pump runs continuously	Stuck relay, sensor fault	Check sensor readings; reset controller; inspect relay.
Low system pressure	Leak, fluid loss	Inspect for leaks; top up heat transfer fluid.
Error code on display	Sensor failure, overtemp	Refer to error code list in manual; check sensor connections.
Collector glass cracked	Hail impact, thermal stress	Replace collector glazing; contact service.

Reset: Press RESET button on controller (if available) or power cycle.
