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
(Image A1)
.
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 con-
sumer 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.
At the solar water heater we place a thermostatic valve, regulated at 38°C to
avoid hot water burns.
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.
ATTENTION!
Before 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
(Image A2)
& 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 over
-
flow (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 safety valve in position
(Image A3)
and discon-
nect 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:
