The manometer is a kind of high pressure equipment, when the heat pump is on, the manometer pointer
2
would point to the pressure value of refrigerant, the max. value of protection is 42kg/Cm . When the heat pump
°
is off, the pointer would point to the same value as actual ambient temperature (e.g. 28 C) and related air
2
pressure (e.g.18kg/ Cm ).
Please check the manometer when you restart the heat pump after not using for a long time, if it shows
°
°
ambient temperature valve is smaller than 2 C
（
When
the
ambient temp. is higher than 2 C
）
, it means that
refrigerant has leaked a lot, and you need to confirm with professional engineer as soon as possible.
