If 2 indoor units are connected and the total pipe length is 30 m with a 6.5 mm (1/
4'') piping diameter, the calculation should be as follows:
(30 m - 7,5 × 2) x 12 = 180gr (refrigerant to be added)

Notices regarding outdoor units
▶ The outdoor unit must not be exposed to machine oil vapour, hot
spring vapour, sulphur gas, etc.
▶ Do not install the outdoor unit directly next to water or where it is
exposed to sea air.
▶ The outdoor unit must always be kept free of snow.
▶ There must be no disruption caused by extract air or operating noise.
▶ Air should be able to circulate freely around the outdoor unit, but the
appliance must not be exposed to strong wind.
▶ Condensate that forms during operation must be able to drain off
easily. Lay a drain hose if required. In cold regions, installation of the
drain pipe is not advisable as freezing could result.
▶ Place the outdoor unit on a stable base.
General notices regarding indoor units
▶ Do not install the indoor unit in a room in which open ignition sources
(for example: open flames, an operating wall mounted gas boiler or
an operating electric heating system) are in operation.
▶ The installation location must not be higher than 2000 m above sea
level.
▶ Keep the air inlet and air outlet clear of any obstacles to allow the air
to circulate freely. Otherwise poor performance and higher noise
levels may occur.
▶ Keep TV, radio and and similar appliances at least 1 m away from the
unit and the remote control.
▶ Do not install the indoor unit in rooms with a high humidity (e.g.
bathrooms or utility rooms).
▶ Indoor units with a cooling capacity of 2.0 to 5.3 kW are designed for
a single room.
Notices regarding ceiling-mounted indoor units
▶ The ceiling construction and suspension system (on site) must be
able to support the weight of the appliance.
▶ Take minimum room area into account
