Installation manual
If the base is placed on a roof, the detritus layer is not needed,
but the concrete surface must be roughened. The standard
concrete mixture ratio is 1:2:4 (cement:sand:cobblestone), and
Φ
10 reinforced steel bar must be used. The surface must be
flattened with cement mortar, and the base borders must be
chamfered.
Before constructing the base, ensure the base directly supports
the rear and front folding edges of the bottom panel vertically,
because these edges are the supported sides of the unit.
To drain off seepage, set up a discharge ditch around the base.
Please check the load capacity of the roof.
When piping from the bottom of the unit, the base height should
no less than 200 mm.

4.5 Outdoor units’ placement sequence &
master and slave unit settings
Set a system with more than two outdoor units as follows: Place
the outdoor units in sequence from large capacity to small.
Mount the largest-capacity unit on the first branch joint site and
set its address as the master unit. Set the other as the slave
unit. Take 48HP (composed by 10HP, 16HP and 22HP) as an
example:
1) Place the 22HP at the side of the first branch joint site.
2) Place the units from large capacity to small (see the detailed
placement illustration).
3) Set 22HP as the main unit, while the 16HP and the 10HP as
the aux. unit.
