3 Electronic balance for charging R410A Can not use the measurable charging tank
4 Torque spanner
5 Flare tool
6 Copper pipe gauge for adjusting projecting margin
7 Vacuum pump adapter Must be with reverse stop valve
8 Leakage detector Can not use freon leakage detector, but the He detector
• 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 ammable gas. Or it will cause re.
• 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 ower or the other vegetable, or the blowing gas will make the ower 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 xed
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 ared 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 nishing 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 ared pipe dimension. Prepare the R410A specially tools according to
the below table.
Safety
• When charging refrigerant, the refrigerant must be taken out as liquid state from the tank.
• When installing the power cord and the connecting line must be at least 1m from the TV or radio, so as to avoid image
interference or noise.
• In the room with uorescent lamp (reverse or fast start type), remote control signal transmission distance may not reach
the predetermined value, so the indoor machine installed away from the uorescent lamp as far as possible.
• Please use the fuse to meet the capacity requirements.
• To prevent the destruction of wires, electrical components, etc. by rats or other animals.
• Recommended room ventilation every 3 to 4 hours.
Arrival inspection
• After receiving the machine, should check whether there is transport damage. If any damage is found on the
surface or inside, it shall be reported immediately to the shipping company in writing.
• Check the product model, electrical parameters (power supply, voltage, frequency) and accessories to
determine whether they meet the requirements.
