3.4 COMMISSIONING.
• The test must be performed only after completing instal-
lation.
• Please check the following points before testing.
• The unit must be installed properly.
• Pipes and electrical cables must be connected properly.
• Pipes pressure test.
• Thermal insulation was done properly.
• Earthing was done properly.
• The supply voltage is the same as the design voltage for the
fan coil.
• The unit's air inlet and outlet are not obstructed.
• The fan coil has been pre-heated with voltage.
Operating test
Use the remote control to set the fan coil in cooling mode
and check the following points, as indicated in the part on
use in this manual. If there is any malfunction, resolve it
using the instructions in the "Troubleshooting support"
section in this manual.
• Check that the unit switches on and off properly from the
remote control.
• Check that all keys on the remote control work.
• Check that the deflectors or fins move properly.
• Check that the internal temperature is properly regulated.
• Check that the indicators on the receiver work properly.
• Check that the condensate drains regularly.
• Check whether there are vibrations or strange noises during
operation.
• Check that the heating capacity is adequate.
• Check for water leaks.
OPERATING RANGE
For safe and efficient operation, use the system with the
following temperatures.
Temperature
Room temperature
Mode
Cooling
Central heating
(without
cooling)
Note: use of the fan coil outside the above conditions could
cause anomalies and malfunctions of the device.
Note: if the relative humidity of the environment is very
high, condensation may form on the surface of the fan coil.
Close doors and windows.
Note: for optimal performance, use the device within the
temperature range indicated.
Note: water system operating pressure: Max: 1.6MPa, Min:
0.15MPa.
ENERGY SAVING TIPS
Read below for energy-efficient operation.
• Adust the flow grid appropriately and avoid direct air flow
on users.
• Adjust the room temperature appropriately. Avoid excessive
heating or cooling.
• Block direct sunlight during cooling operations with cur-
tains or blinds.
• Using the unit does not guarantee ventilation of the envi-
ronment.
• Keep doors and windows closed. If doors and windows
stay open, the air will escape from the room and reduce
the heating or cooling effect.
• Do not place objects next to the unit's air inlet and outlet
to prevent the effects from falling or stopping the device.
• Set the timer.
• In case of long downtime, remove the batteries from the
remote control. When the supply voltage is connected, a
small amount of energy is used up even if the fan coil is not
working. Disconnect the supply voltage to save energy.
• Keep the indoor unit and the remotecontrol at least 1 m
away from televisions, radios, stereos, and other similar
devices. Failure to comply with the above may result in
static or distorted images.
• Clean the air filter at least once every fortnight to prevent
the dirt inside from reducing cooling or heating efficiency.
