LOAD OF COMPLEMENTARY COOLING FLUID
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.

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 between the gas temperature at the condenser inlet and the condensation
temperature must be within the range 40ºC to 45ºC.

SYSTEM START-UP
The Eco commissioning is assured by the correct installation achieved and by the respect of all installation
instructions. Increasing water temperature from 10° C to 55° C (50º F to 131º F) will vary between 4 to 8
hours, depending on weather conditions and type of installation.
It is always possible to do a tune of thermal expansion valve to adapt the system to a suitable outside
weather conditions by the temperatures extrapolation method.
Fill the hot water tank with water and purge the existing air, opening a hot water tap/faucet.
Check if the valves are properly working and if the system is filled with fluid.
Once the tank is full, energize the water heater. Press the POWER button on the user interface to turn the
water heater on. Once powered, the control will display a reminder to ensure the water heater is full.
Press POWER again to acknowledge that the water heater is full.
