Product Description:

This is a pressurized system, with jacketed tank and flat panel solar collector combined. We call it compact flat panel pressurized solar water heater.

This closed loop system can prevent freezing and scale. Heated glycol-water mixture solution from the collector flows into the tank’s jacketed shell heat-exchanger and then returns to the collector after heating up the domestic water.

How It Works:

The system operates on the thermosiphon principle, meaning that heat transfer occurs entirely by means of natural convection, without pumps and control units. The solar fluid heated in the collector rises and transfers heat through a highly efficient jacketed shell. High-selectivity harp absorbers are used to guarantee the highest possible solar yield in this system.

Closed Loop Flat Panel Solar Water Heater Manual

  • Thank you for selecting our closed loop flat panel solar water heater with so many advantages. Elegant shape, high efficiency, working under pressure, easy to use、safe and reliable. it’s your best solution to supply hot water for family. Please read carefully the manual before use.
  • Please check accessories and user’s manual according to the packing list when opening the package.
  • Local agent or franchised store take charge of the installation& trail run and after service, please write down the telephone number and address of the store where you purchase from in order to get our timely service.
  • Both package and warranty card have serial number. Neither no series number nor damaged series number may be fake. please pay more attention to it.
  • Make sure to mix hot and cold water before shower or washing. Otherwise.it will cause severe burn.
  • Warning: Please fill up with cold water before heated by electrical back up element
  • Use hot water while the electrical back up element is working is strictly forbidden.
  • The connection of wire is “X” way. You must use sheathed copper wire with three cords(size:≥1.5mm2)when you install or replace the wire.
  • Please keep the cold water valve open at all times.

1) Advanced Technology

Closed loop flat panel solar water heater with separate water tank and flat panel can get hot water according to thermosiphon principle. Enamel coated inner tank is made of special metal material. formed up with advanced punching technology and atuo non-electrode replacing welding technology. a special silicate is sintered by high temperature to the wall of inner tank.forming a special protection layer with no leakage, no corrosion, no scale advantages .

2) Flat panel

The most efficient Germany imported blue titanium selective coating.

Minimize the damage to absorption layer and copper pipe with whole plate laser welding.

High strength special low-iron tempered glass with transmittance more than 92%.

High quality assured with advanced producing process technology and equipment.

3) Double Protecting

Imported P/T valve provides the automatic pressure release and protects the water tank against the influence of high temperature and pressure. One-way water-in release valve can drain out water automatically and resist the influence of super-high water pressure outside.

4) Aluminium Alloy Bracket

It’s made of Al-Mg-Si antirust aluminium alloy material and produced by advanced numerical control(NC) equipment with high hardness and strength.

5) Wide Scope Of Application

The jacket type structure with medium which will not freeze under -35℃ has high heat exchange efficiency and high systematic stability. it can be installed and used in the tropic, temperate zone and frigid zone.

7. Installation of intelligent controller:

Caution

● The socket and plug should be connected well.

● If auxiliary electric heating system installed, do connect the live wire, null wire and ground wire correctly with power-leakage protection plug. The socket should be connected to ground reliably.

● Use tri-wire plug of safe protection, and the rated current value of socket ≥16A

● Safe measures should be taken and layout to specification.

● Installation of digital solar controller

Caution:

● The light collecting plates should face south with nothing blocked, and supports be reliable to anti-strong wind.

● Filling water: The heater is filled water by pressure and free of filling device, water will be automatically filled till fullness and then stops.

● Using water: Water can be used under pressure.

If your water heater is in abnormal use, please make inspection and treatment step by step according to “fault and disposal”; if you can’t resolve or have something unclear, you shall contact with the appointed authorized maintenance service by company or the service center in various areas and our company will make full service for you. The irresistible natural disaster is excluded in service scope. Thanks for cooperation.
