5.6. Connect the drain pipe
■ Install the drainpipe of the indoor unit
Please use sealing materials and pipe sheath (fitting) when connecting PVC pipes.
♦The drain pipe of indoor unit must be heat insulated, or it will condense dew, as well as the connections
of the indoor unit.
♦ Hard PVC binder must be used for pipe connection, and make sure there is no leakage.
♦ With the connection part to the indoor unit, please be noted not to impose pressure on the side of indoor
!
unit pipes.
CAUTION
♦ When the declivity of the drain pipe downwards is over 1/100, there should not be any winding.
♦ The total length of the drain pipe when pulled out transversely shall not exceed 20m, when the pipe is
over long, a prop stand must be installed to prevent winding.
♦ Refer to the figures on the right for the installation of the pipes.
■ Drainage test
● The figure below indicates how to test the condensate drain connection. During these operations the tightness of the pipe
must be checked (to prevent leaks inside the unit) and correct drainage towards the external run-off, to prevent returns
inside the unit.
● Pour 600 cc of water in the drain pan from the air outlet for confirming correct drainage.
5.7. Outdoor unit installation
5.7.1. Installation place
■ The outdoor unit should be installed in the location that meets the following requirements:
There is enough space for installation and maintenance.
The air outlet and the air inlet are not impeded, and can not be reached by strong wind.
It must be a dry and well ventilating place.
The support is flat and horizontal and can stand the weight of the outdoor unit. And will no additional noise or vibration.
Your neighbourhood will not feel uncomfortable with the noise or expelled air.
It is easy to install the connecting pipes or cables.
Determine the air outlet direction where the discharged air is not blocked.
There is no danger of fire due to leakage of inflammable gas.
The piping length between the outdoor unit and the indoor unit may not exceed the allowable piping length.
In the case that the installation place is exposed to strong wind such as a seaside, make sure the fan operating properly
by putting the unit lengthwise along the wall or using a dust or shield. (Refer to figure below)
