To perform a test run
INFORMATION
If the unit runs into an error during commissioning, see the
service manual for the detailed troubleshooting guidelines.
Prerequisite: The power supply MUST be in the specified range.
Prerequisite: Test run may be performed in cooling or heating
mode.
Prerequisite: Refer to the operation manual of the indoor unit for
setting temperature, operation mode....
1 In cooling mode, select the lowest programmable temperature.
In heating mode, select the highest programmable temperature.
The test run can be disabled if necessary.
2 When the test run is finished, set the temperature to a normal
level. In cooling mode: 26~28°C, in heating mode: 20~24°C.
3 Make sure that all functions and parts are working properly.
4 The system stops operating 3 minutes after the unit is turned
OFF.
INFORMATION
▪ Even if the unit is turned OFF, it consumes electricity.
▪ When the power turns back on after a power break, the
previously selected mode will be resumed.

NOTICE
General maintenance/inspection checklist. Next to the
maintenance instructions in this chapter, a general
maintenance/inspection checklist is also available on the
Daikin Business Portal (authentication required).
The
general
maintenance/inspection
complementary to the instructions in this chapter and can
be used as a guideline and reporting template during
maintenance.
NOTICE
Maintenance MUST be done by an authorised installer or
service agent.
We recommend performing maintenance at least once a
year. However, applicable legislation might require shorter
maintenance intervals.
NOTICE
Applicable legislation on fluorinated greenhouse gases
requires that the refrigerant charge of the unit is indicated
both in weight and CO

Formula to calculate the quantity in CO
tonnes: GWP value of the refrigerant × total refrigerant
charge [in kg] / 1000
DANGER: RISK OF ELECTROCUTION
Disconnect the power supply for more than 10 minutes,
and measure the voltage at the terminals of main circuit
capacitors or electrical components before servicing. The
voltage MUST be less than 50 V DC before you can touch
electrical components. For the location of the terminals,
see the wiring diagram.
