7. RUNNING AND CAPABILITY
7.1 About the 3-minute protection
Restart or open the manual switch after the unit has shut down.
Unit will not start immediately until 3 minutes later, because of the
self-protect function of the compressor.
7.2 Characteristics of heat pump heating
operation
During operation, if outdoor temperature is higher than normal,
the air supply motor will runs at low air volume or stop running.
7.3 About defrosting function perform at
heating operation
1)
In case of the unit requiring deicing during heating operation, TO
prevent the heating efficiency from decreasing, defrosting opera-
tion will turn on automatically (approx. 2~10 minutes) .
2)
In the process of defrosting operation, the unit air supply motor
will stop running.
3)
Reminder: During the defrost cycle a steam cloud (water vapour)
