6 - OPERATION TEST
The operation test must be carried out only after completing the following procedures:
- Electrical safety checks;
- Check for gas leakage;
- Check that the valves on the gas side and on the liquid side (high or low pressure) are completely open.
Carry out the operation test as described below:
The operation test must be carried out for at least 30 minutes.
a. Connect the unit to the mains supply.
b. Press the ON/OFF key to switch the unit on; press the MODE key to scroll between the functions below,
one at a time:
• COOL – Select the lowest possible temperature
• HEAT – Select the highest possible temperature
Leave each function active for 5 minutes.
During the operation test, carefully check that no one of the points of connection of
the coolant pipes shows any leakage.
c. At the end of the operation test, if all the checks listed in the table below have a positive result, proceed
as follows:
• Use the remote control to take the unit back to its normal operating temperature.
• Use insulating tape to wrap the points of connection of the coolant pipes located inside and that have
been exposed during installation of the internal unit.
If ambient temperature is lower than 17°C, the cooling function (COOL) does not ac-
tivate. In this case, use the manual control as described in its respective paragraph.
Table of the checks to be carried out:
