After piping work is finished, check if drainage flows smoothly.• Open the water inlet lid, add approximately 2 l of water graduallyand check the drainage flow.Method of adding water. See figure 10.If adding water from the charge inlet at the fan casing, be sure to putthe lid back in its original position.When electric wiring work is finishedCheck drainage flow during COOL running, explained in chapter"Test operation" on page 7.When electric wiring work is not finished■ Remove the switch box lid and connect the power supply andremote controller to the terminals.See figure 11.• Next, press the inspection/test operation button on theremote controller. The unit will engage the test operation mode.Press the operation mode selector button until selecting fanoperation . Then, press the on/off button . The indoor unitfan and drain pump will start up.

For detailson hooking up the remote controller, refer to the "Installationmanual of the remote controller".■ All wiring must be performed by an authorized electrician.■ A circuit breaker capable of shutting down power supply to theentire system must be installed.■ This system consists of multiple indoor units. Mark each indoorunit as unit A, unit B..., and be sure the terminal board wiring tothe outdoor unit and BS unit are properly matched. If wiring andpiping between the outdoor unit and an indoor unit aremismatched, the system may cause a malfunction.Electrical characteristicsMCA: Min. circuit Amps (A)MFA: Max.
