Water Pump working interface display
Compressor protection time not shown:
“Pump working countdown”:
indicates: No matter in which working state and interface,
as long as the pump works, this interface appears and counts down to 28 seconds.
However,the interface only displays the previous working status and interface after 3
seconds.For example, after 3 seconds, there is a drainage icon on the main interface and
it will flash until the drainage is finished.
Interface display in case of failure
Machine running time fault display:
Make fault judgment and take corresponding actions after
starting up. Regardless of the state, the fault is executed
first and the fault code is displayed on the interface. If there
is a fault in the sub-menu operation, immediately return to
this interface display fault (including defrosting state). (the
fault is judged when the pump works, and the fault is
displayed as usual, but the pump needs to complete the
water pumping this time). Multiple faults can be displayed
at the same time.
DESCRIPTION OF FAULT DISPLAY:
Humidity sensor fault: when the humidity sensor unit fault or signal can not be
transmitted, the fault is judged to be E1. The machine is out of operation (power on again
after troubleshooting). Pump button can operate.
Ambient temperature T≤2
℃
: When the sensor continuously detects the ambient
temperature of inlet air T=2 degrees for 600 seconds, the fault is judged to be LO and the
whole machine is stopped. Other values,corresponding to the temperature region
operation. (recoverable). At this time, the interface cannot be operated. The pump button
an be operated.
Ambient temperature T≥45
℃
: When the sensor continuously detects the inlet air
environment temperature T=45 degrees for 15 seconds, the fault is judged to be HI and
the whole machine is stopped.Other values, corresponding to the temperature region
operation. (recoverable). At this time, the interface cannot be operated. The pump button
can be operated.
MAINTENANCE INSTRUCTIONS
Check the power cord for signs of damage such as fraying: Replace the cord before useif
there is any damage.
Check the filter for signs of dirt or obstructions. Clean or replace the filter as necessary.
