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 checklist is 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.

Applicable legislation on fluorinated greenhouse gases requires that the refrigerant
charge of the unit is indicated both in weight and CO

equivalent.
Formula to calculate the quantity in CO
2
equivalent tonnes: GWP value of the
refrigerant × total refrigerant charge [in kg] / 1000
DANGER: RISK OF ELECTROCUTION
Disconnect the power supply for more than 10minutes, and measure the voltage at
the terminals of main circuit capacitors or electrical components before servicing.
The voltage MUST be less than 50VDC before you can touch electrical components.
For the location of the terminals, see the wiring diagram.
