1. Installation Methods: Based on the principles of field usability and maintenance convenience, the unit can be installed using either DIN-rail mounting or bracket hanging via the support mounting hardware. Secure the unit with M4 screws, ensuring it remains perfectly horizontal without any tilting.
2. Clearance Requirements: Maintain a clearance of greater than 10 cm between all sides of the device and surrounding objects to ensure unobstructed airflow from the fan vents.
3. Drainage Tube Setup: Connect one end of the water drainage tube to the outlet port of the device and secure it with a hose clamp. Keep the tube straight and untangled along its path to facilitate smooth drainage, and lead the other end outside the cabinet.

Note: Models without “T” in the model number do not have dew-point detection.
1. Automatic defrost:
All series have an automatic defrost function. When frost forms on the condensing plate, the dehumidifier defrosts automatically before resuming dehumidification.
2. Low-temperature heating (optional, selected according to site conditions):
When the dehumidifier detects that the ambient temperature is low, it automatically switches on an external heater for temperature compensation.
