Water leak Detector
Lay water leak detectors and confirm the alarm information through the controller. The detector should be
located away from any water pool or drainage trench on the floor, 2 to 2.5 meters away from the unit. Do
not place it directly under the machine.
Figure 3-37 shows the recommended location for the water leak detector:

Ensure that the power supply of the control unit has been disconnected before connecting
any mechanical parts or cables.
Do not use the water leak detector in the vicinity of flammable liquids; do not use it to
detect any flammable liquids.
3.2.5 Air Filter Maintenance
The efficiency of the configured filter is 30%, in compliance with industry standards such as the America
ASHRAE52-76 and Eurovent 4/5 standard; the dust resistance value is 90% (EU4 standard).
Set the filter maintenance and alarm logic to ensure efficient operation. The fan operating time is
2160 hours by default (though the time is set and customized based on the local operating
environment); the filter maintenance alarm is triggered based on the configuration and settable
operation time.
Check and replace the filter according to its dust and clogging condition. During normal
operations, the filter needs to be checked once a month and replaced as per the requirement.
Cut off the power before replacing the filter. Clear the fan operating time after replacing the
filter.
