(2) The indoor unit does not have an air filter installed. The air filter must be installed at a location like an air inlet where it can be easily maintained. (Without an air filter, dust particles may stick to the air heat exchanger which will make the air conditioner prone to failures and water leakage.) (3) Before installing the air duct, ensure that the static pressure of the air duct is within the permitted range of the indoor unit (see section 6.2).
Set proper external static pressure (ESP) according to the actual installation Figure 7.2 shows the power supply terminal of the indoor unit. conditions. Otherwise it may cause some problems. If the connecting duct is long and the ESP setting is small, the airflow will be very small, leading to poor performance.
