Unit Reference value
● During cooling operation, the
electronic expansion valve of heating is
3000PLS;
PLS
● During heating operation, the
adjustable range of the opening of
electric expansion valve opening is
720~3000PLS.
Hz ● Change among 20Hz~140Hz
● IPM module temperature is lower than
80℃(176℉). The highest temperature
℃ （℉）
doesn't exceed 95℃(203℉).
● The normal bus voltage is 1.414 times
of the power supply voltage. For
example, if the three-phase power supply
voltage is 460V, then the rectified bus
V
voltage is: 460V×1.414 = 650V. The
normal deviation between the measured
value and the calculated value within
15V.
● Adjust the operation in the range of
0~75Hz according to the system
Hz
pressure adjustment.
● According to the ambient temperature,
the inlet temperature is 1℃(33.8℉) ~7℃
℃ （℉）
(44.6℉) lower than the outlet
temperature for the same indoor unit
under cooling mode.
●The inlet temperature is 10 ~20℃
℃ （℉）
(50~68℉) lower than the outlet
temperature for the same indoor unit
under the heating mode.
● 2000PLS electronic expansion valve:
the opening is adjusted automatically in
the range of 200~2000PLS;
PLS
● 480PLS electronic expansion valve:
the opening is adjusted automatically in
the range of 70~480PLS.
● The indoor unit drains smoothly and
thoroughly, and the condensate water
pipe has no slope water storage; the
—
outdoor unit can drain water from the
drain pipe without dripping directly from
the unit foundation.
●There is no abnormal noise for the
operation of the compressor, indoor fan
—
and outdoor fan. The unit is running
normally.
