Ono sto si ti gore napisao, i sto ZAISTA pise u Service Manual se ipak malo razlikuje. Uostalom, evo ti, pa i sam prosudi:
Condition and process of defrost:
When duration of successive heating operation is more than 45 minutes, or accumulated heating time more than 90 minutes, and one of the
following conditions is reached, the unit will enter the defrost mode after 3 minutes.
(1). T outdoor ambient > 5°C(41°F), T outdoor tube≤-2°C(28.4°F);
(2) -2°C≤T outdoor ambient < 5°C(41°F),, T outdoor tube≤-6°C(21.2°F);
(3) -5°C≤T outdoor ambient < -2°C(28.4°F), T outdoor tube≤-8°C(17.6°F);
(4)-10°C≤T outdoor ambient < -5°C(23°F);, T outdoor tube-T compensatory ≤ (T outdoor ambient-3°C(5.4°F))
(5)T outdoor ambient < -10°C(14°F), T outdoor tube-T compensatory ≤ (T outdoor ambient-3°C(5.4°F))
(after energizing, T compensatory=0°C(32°F) during the first defrosting; if it is not the first defrosting, T compensatory is confirmed by T outdoor
tube of quitting last defrosting: a. when T outdoor tube > 2°C(35.6°F), T compensatory=0°C(32°F); b. when T outdoor tube ≤ 2°C(35.6°F),
Tcompensatory=3°C(37.4°F))
At that time, the indoor fan stops and the compressor stops, and after 30 seconds the outer fan will stop, and then after 30 seconds,the fourway
valve will stop. After 30 seconds, the compressor is initiated for raising the frequency to defrost frequency.When the compressor has
operated under defrost mode for 7.5 minutes, or T outdoor ambient ≥ 10°C, the compressor will be converted to 46Hz operation. After 30
seconds, the compressor will stop. And after another 30 seconds, the four-way valve will be opened, and after 60 seconds, the compressor
and the outer fan will be started, the indoor fan will run under preset cold air prevention conditions, and H1 will be displayed at temperature
display area on the display panel. Defrost frequency is 85Hz.
