4.4.7. Load of Complementary Cooling Fluid

The warranty does not apply to
distances longer than what has
been established for the pre-load
(12m)
Your unit has been pre-loaded for connections up
to 12 m between the panel and the storage water
heater. Longer distances will decrease the
performance of your equipment.
Before carrying out an additional load of gas into
you equipment, you must prepare all the
equipment and tools necessary for the operation,
such as:

Gas bottles and their hoses

Hexagonal-tip wrench to open the 3-way
valve

Scale with precision of 10 g
To carry out a complementary load of gas, follow
these steps:
a) Place the cooling fluid tank on a scale with
a 10 g precision and take note of the
weight.
b) Connect the hose of the cooling fluid tank
(R134a) to the inlet of the 3-way valve
c) Switch off the compressor on the
electronic panel.
d) Open carefully and only slightly the
handle of the cooling fluid tank, notice the
variation of the figure indicated in the
scale (as you load fluid into the circuit, the
figure for the weight in the scale will
decrease).
e) When your reach the figure intended for
the injection of cooling fluid into the
circuit, close the tank handle and remove
the hose connected to the 3-way valve.
f) Switch on the compressor again and
check how it runs.

4.4.8. Checking good running condition

To check whether your equipment is running
correctly, start it and wait at least 20-30 minutes
and then check these conditions:

Overheating, without solar radiation
directly over the panel, should be within
the range 5ºC to 10ºC.

The gradient
temperature at the condenser inlet and
the condensation temperature must be
within the range 40ºC to 45ºC.

4.5. Hydraulic Couplings

WARNING / DANGER
The water you use may contain impurities and/or
substances damaging to the system and even
harmful to your health. Make sure you use water
with quality fitting for home consumption. The
following table indicates some parameters
according to which water must be subjected to
chemical treatment.
Hardness pH
(ºdH)
3,0 up to 20,0 6,5 up to 8,5
3,0 up to 20,0 <6,5 up to
>8,5
<3,0 or >20,0 --------------
To assemble the couplings of the hydraulic circuit
you must:
a) Connect the water inlet and outlet of the
equipment with a pipe and fittings that can
cope with constant temperature / pressure
of 75 ºC / 7 bar. For this reason we
recommend the use of piping with
resistance to high
pressure. We recommend the use of pipe
type PEX, PPR, MULTICAMADA, amongst
others.
