4．Features
4.1 New structure design
The module adopts new structure design, H shape condenser, 360Oair suction, increased the heat
exchanging area, efficiently enhanced the heat exchange efficiency.
4.2 Modular design, flexible combination
The unit adopts modular design, which can make more units to connect together. The maximum
combination of the system consists of 1 main unit and 15 slave units. Cooling (heating) capacity range is
from 35kW to 2080kW，meanwhile every separate module can operate as main unit, also each module can
be a slave unit with modules combination, more convenient for design and installation.
4.3 Backup functions
When unit is failed
If master unit fails, all the units will stop.
If one slave unit fails, this unit will stop but the others will keep running.
When the master unit fails, any of the slave one can be set as the master unit by manual setting.

When unit is under protection
If master unit’s protection happens, this unit will stop but the others will keep running.
If slave unit’s protection happens, this unit will stop but the others will keep running.
( Except PE, P9 protection happens)
PE：Low temperature protection of evaporator
P9：Outlet and inlet water temperature difference protection
4.4 Alternative cycle duty operation
In one combination, all slave units operate as alternative in cycle duty to keep equal running time,
realize higher stability, better reliability and longer lifespan.
(For example, five modules combination, no.1 is master unit, others are slave units.)

4.14 Anti-corrosion protection (optional)
Outdoor units are given anti-corrosion treatment for non-extreme conditions as standard and can also be
customized with heavy anti-corrosion treatment on steel sheets, grills, coil fins, electric control box case and
screws/bolts for surface protection against corrosive air, acid rain and saline air (for installations in coastal
regions) to extend overall useful life.
