SOLAR WATER HEATERS
HYDRAULIC CONNECTION
CONNECTING THE SYSTEM WITH THE COLD AND HOT WATER MAINS
The “COLD WATER INLET” and “HOT WATER OUTLET” sockets colored blue and red respectively are located on
the side of the water storage tank.
ATTENTION!
The connections to the hot and cold water pipes should be made with union nuts and not by soldering.
1. Onto the “COLD WATER INLET” safety valve (10 bar) is screwed first, followed by a mini ball valve. The cold
water pipe is then connected to the ball valve with an insulated plastic pipe (Drw 1).
NOTE: The safety valve should have a drain pipe connected to its outlet. This pipe should run to ground level
where hot water discharge is safe and clear of any paved areas. Do not seal or block the ends of this drain pipe
or the valve outlet. Drinking water may be drained from this pipe during high irradiation situations.
2. The “HOT WATER OUTLET” is then connected to the hot water pipe of the consumer network through an
insulated plastic pipe ( Plastic pipes are recommended to minimize electro-corrosion).
3. Filling the water storage tank WITH WATER: With the ball valve and a hot water tap open, the water storage tank
is allowed to be filled with cold water. When water starts to run out of the tap, the water storage tank is full and
the hot water tap can be closed.
4. In order to avoid overheating at the consumption points, a thermostatic mixing valve must be installed at the
outlet of the solar water heater.

CLOSED LOOP FILLING
ATTENTION!
B efore starting to fill the closed loop with anti freeze liquid, the water storage tank has to be
completely filled with water.
1.
Connect the water mains to the specially designed filling fitting on the right of the water storage tank (Drw 2) & fill
approx. half of the closed loop. Add water to the anti freeze liquid, putting double quantity of water in an empty
pot. Disconnect the water mains from the filling fitting & empty the anti freeze liquid solution that we have
prepared with the help of a funnel. Connect again the water mains and fill the closed loop completely.
ATTENTION!
The last filling phase should be realized with controlled flow, given that at the closed loop overflow
(3.5 bar safety valve connection point) the fluid may reach high temperatures, which may mean risk of skin burns.
2.
When the closed loop is completely filled, securely tighten the 3.5 bar safety valve in position (Drw 3) and
disconnect the mains from the special filling fitting.
3. Uncover the collectors and clean the glass removing all the information stickers.
4. Check for leaks and make sure that all pipe joints to the collectors and the water storage tank, as well as the
cold & hot water pipes towards the system are properly insulated, in order to avoid thermal loss and protect them
against frost.
5. After the completion of the installation, no hot water should be consumed for a couple of hours (depending on the
weather conditions and the solar irradiation), in order for the closed loop to be set in operation.
ANTI FREEZE LIQUID is an advanced, propylene glycol based special product, designed and formulated in order
to ensure effective heat transfer properties at high or low temperatures. It is non-toxic and provides protection up
to -37°C (solution 55% v/v with water). It is especially designed to provide excellent anticorrosion properties. In
aquacius solutions anti freeze liquid offers protection according to the extent of dilution as per in the table below:
