Haier AV08IMVEVA Installation Manual page 4

Safety
• Execute earthing for the unit. But the earthing wire can not be connected to the gas pipe, water pipe, lightening rod or
the telephone earthing wire. Improper earthing will cause electric shock.
• Don't install the unit at the place where leaks the flammable gas. Or it will cause fire.
• Execute the water drainage pipe according to the manual, improper installation will cause water leakage to wet the
family things.
• The outdoor fan can not face to the flower or the other vegetable, or the blowing gas will make the flower dried up.
• Please ensure the maintenance room, if not, it will cause the maintenance person damaged.
• When installing the unit on the roof or the other high place, to prevent the person falling down, please set the fixed
ladder and the railing at the passage.
• Use the two-end spanner, and fasten the nut at proper torque. Don't fasten the nut excessively against the flared setion
broken. Or it will cause refrigerant leakage and lack of oxygen.
• Take measures for heat insulation to the refrigerant pipe, or there will be water leakage or dew drop to wet the family
things.
• After finishing the refrigerant pipe, make leakage test by charging the nitrogen. In case the refrigerant leaks in a small
room and exceeds the limited concentration, it will cause lack of oxygen.
• Don't use the other refrigerant except for R410A. The R410A pressure is 1.6 times higher than R22 pressure. The
refrigerant R410A tank is marked with pink sign.
• Against charging different refrigerant, we changed the stop valve diameter of the R410A unit. To enhance the
compression consistance, we also changed the flared pipe dimension. Prepare the R410A specially tools according to
the below table.
R-410A specified tools
1 Gauge manifold
2 Charge hose
3 Electronic balance for charging R410A
4 Torque spanner
5 Flare tool
6 Copper pipe gauge for adjusting projecting margin
7 Vacuum pump adapter
8 Leakage detector
• When charging refrigerant, the refrigerant must be taken out as liquid state from the tank.
• When installing indoor unit, outdoor, power cable and connecting wire, leave them at least 1m away from the TV set or
the radio against interference for the image or the noise.
• In the room with fluorescent lamp (reverse phase or rapid start type), the remote signal may be not reach the pre-set
distance. The farther that indoor is away from fluorescent lamp, the better.
• The tightening torque of the stop valve refer to the following table
Operating valve size

Ø6.35
Ø9.52
Ø12.7
Ø15.88
Ø19.05
• When loaded into a refrigerant, be sure to take it out of the tank.
• Installation of indoor, outdoor, power lines and connections must be at least 1m away from the TV or radio to avoid
image interference or noise.
• In a room equipped with fluorescent lamps (RP or fast start), the remote control signal transmission distance may not
reach a predetermined value. The farther away the indoor machine is, the better it is.
