Installation for external output
Installation of the drain pipe: The pipes must have a downward slope (of at least 1/100).
Duct installation: Make sure the duct is large enough to support the desired volume of air. Be careful not to make any calculations of the external static pressure.
Insulation work: Take special care when closing all gaps at the locations of connections to the indoor unit and at the joints in the bypass kit. Do not forget the drain pipes.
Electrical work (control and power wires): Use two shielded wires with two cores and use separate power supplies for the indoor and outdoor units.
Various switch configurations: Arrange the switches correctly, as indicated in the wiring control system diagram.
Installing the outdoor unit base: Make sure the base is level.
Installation of the outdoor unit: Make sure the air flow is adequate and the space for maintenance around the outdoor unit is sufficient. Clearly indicate the names of the
system.
External circulation, installation of the refrigerant pipe: From the external outlet to the external unit.
