1.5 Master and slave unit setting
When the quantity of outdoor unit is more than two in one system, the outdoor unit should be set in order from
largest capacity unit to smallest capacity unit. The largest capacity unit must be placed on the first branch site,
and be set as master unit, while the others are set as slave units.
Take 44HP (composed by 10HP, 16HP and 18HP) as an example:
1) Place the 18HP on the first branch site.
2) Order the units from the largest capacity to smallest (See the detail placement illustration)
3) Set 18HP as the master unit, the 16HP and the 10HP as slave units.
1.6 Installation space
Ensure enough space for maintenance. Modules combined in the same system must be on the same
height.
