9.5 Parameter Number and Description Table.
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
2
air 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.
NOTE: the machine off code (The No. 13, parameter in the previous table):
2: Water tank temp. sensor breakdown
3: Evaporator coil temp. sensor breakdown
4: Discharge temp. sensor breakdown
5: Discharge temp. is too high, switch off the unit
11: Anti-frozen finished, switch off the unit
12: High-pressure switch cutting
13: Meet set temp
14: Controller power off
No. 32
19: Water flow switch breakdown
