Outdoor Unit Ducting - Sinclair SDV6 User And Installation Manual

9.3 Outdoor Unit Ducting

The following principles shall be followed when installing the air
guide device:
Before installing outdoor unit ducting, be sure to remove
the unit's steel mesh cover; otherwise, airflow will be
adversely affected.
Each duct should contain no more than one bend.
Vibration isolation should be added to the connection
between the unit and the ducting to avoid vibration/noise.
The addition of louvers will affect the air output of the unit,
so the use of louvers is not recommended. If you want to
use a louver, please keep the shutter angle below 15 ° and
ensure that the effective opening rate of the shutter is more
than 90%.
If more than one outdoor unit needs ducting, each outdoor
unit should have independent ducting. A single ducting
cannot be shared by multiple outdoor units.
According to the actual static pressure of the outdoor unit
ducting, select an appropriate static pressure mode. Refer
to section 6.2.
