<Important Note>
All these DIP switches on PUHZ-HW·HA(2) are set as shown above.
Spare PCBs, however, will be supplied without any settings, which means that all Dip switches are switched OFF.
When servicing, please make sure to set all switches correctly, referring to the previous PCB which is removed from the unit.
*1
Manual defrost should be done as follows.
1
Change the DIP SW1-1 on the outdoor controller board from OFF to ON.
2
Manual defrost will start by the above operation
1
if these conditions written below are satisfied.
• Heat mode setting
• 10 minutes have passed since compressor starts operating or previous manual defrost is finished.
• Pipe temperature is less than or equal to 8
:
.
Manual defrost will finish if certain conditions have been satisfied.
Manual defrost can be done if above conditions have been satisfied when DIP SW1-1 is changed from OFF to ON.
After DIP SW1-1 is changed from OFF to ON, there is no problem if DIP SW1-1 is left ON or changed to OFF again.
This depends on the service conditions.
