3.3 Check before Commissioning
3.3.1 Selection of Installation Position
3.3.1.1 Installation Position of the Unit
(1) The unit is installed in a spacious room with good ventilation. The air inlet and outlet are not
blocked.
(2) A drainage ditch or outlet is available near the installation position to facilitate water drainage.
(3) The foundation or support is solid and secure to ensure stable operation of the unit.
(4) The unit must be installed in a horizontal manner without any tilt.
(5) The position for installing the water tank must have sufficient load-bearing capacity.
(6) The drain outlet for water tank is near the drainage ditch or drainage hole.
3.3.1.3 Installation Position of the Wired Controller
(1) The wired controller is not installed in a place with high temperature and high humidity, such as the
kitchen and bathroom.

Note:
①
The power cable of the unit must be a copper-core cable. The work temperature must meet the related
requirement.
②
If the power cable is more than 15 m. Its cross-sectional area must be expanded accordingly to avoid
overload.
③
As a category-I appliance, the unit must be reliably grounded.
④
The power cable specification refers to the specification adopted when the BV single-core cables (2-4
pieces) are led through a plastic pipe and the work temperature is 40°C. The circuit breaker is D-type and it
is used under temperature of 40°C.
⑤
If the installation conditions on site change, consider using cables whose reduced capacity can still
meet site requirements, based on the specifications of the power cables and air circuit breakers provided by
the vendor.
