Jxecute earthingfor the unit4 Gut the earthingwire can not be connected to the gas pipe2 water
pipe2 lighteningrod or the telephone earthingwire4 Nmproper earthingwill cause electric shock4
Ion-t install the unit at the place where leaks the flammable gas4 Tr it will cause fire4
Jxecute the water drainage pipe according to the manual2 improper installation will cause water
leakage to wet the family things4
Yhe outdoor fan can not face to the flower or the other vegetable2 or the blowing gas will make
the flower dried up4
Ulease ensure the maintenance room2 if not2 it will cause the maintenance person damaged4
\hen installingthe unit on the roof or the other high place2 to prevent the person fallingdown2
please set the fixed ladder and the railingat the passage4
Zse the two3end spanner2 and fasten the nut at proper torque4 Ion-t fasten the nut excessively
against the flared setion broken4 Tr it will cause refrigerant leakage and lack of oxygen4
Yake measures for heat insulation to the refrigerant pipe2 or there will be water leakage or dew
drop to wet the family things4
Ffter finishing the refrigerant pipe2 make leakage test by charging the nitrogen4 Nn case the
refrigerant leaks in a small room and exceeds the limited concentration2 it will cause lack of
oxygen4
Ion-t use the other refrigerant except for W:76F4 Yhe W:76F pressure is 74< times higher than
W88 pressure4 Yhe refrigerant W:76F tank is marked with pink sign4
Fgainst charging different refrigerant2 we changed the stop valve diameter of the W:76F unit4
Yo enhance the compression consistance2 we also changed the flared pipe dimension4 Urepare
the W:76F specially tools accordingto the below table4
\hen charging refrigerant2 the refrigerant must be taken out as liquid state from the tank4
