Drive bus voltage of
inverter compressor
V
● The normal bus voltage is 1.414 times
of the Power voltage. For example, if the
three-phase Power voltage is 208V, then
the rectified bus voltage is: 208V×1.414
= 294V. The normal deviation between
the measured value and the calculated
value within 15V.

℉
)
~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.

Opening of indoor
electronic expansion
valve
PLS
● 2000PLS electronic expansion valve:
the opening is adjusted automatically in
the range of 200~2000PLS;
● 480PLS electronic expansion valve:
the opening is adjusted automatically in
the range of 70~480PLS.

17 Drainage
system
—
—
● 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.
