    Refer to the following figure for the distance between the

    foundation bolts.

(2)When the refrigerant pipe is connected from the bottom of

     the unit,the unit should be raised at least 500mm(see the

     figure below)

(3)In snowy regions,snow-proof facilities should be used(see

    the figure below).

    (Poor snow-proof facilities may lead to damge.To avoid

    inconveniences,the unit should be raised and snow-proof

    covers should be installed at the air inlet and outlet.)

(4)During installation,anti-vibration rubber pads should be

     used between the machine and the bracket.

3.Connection of refrigerant pipe

During installation,if refrigerant leakage occurs,ventilation measures must be taken.When refrigerant

meets with fire,hazadous gas will be produced.

After installation,make sure that there is no refrigerant leakage.

Refrigerant,if meeting with heaters and stoves,ect in the room,may produce hazardous gas.

Connection of refrigerant pipe

(1) The joints of the refrigerant pipe are inside the unit.Take off the access hole cover in front of the unit.

(2) The pipe can be connected from the front or bottom of the outdoor unit.

(3) Remove the L-shaped pipe from the valve by welding and connect the accessory pipe to the valve.

(4) In the case of front connection,cut the accessory pipe at the height of the fixing panel.Then join the

      pipe with an elbow and let it go through the fixing panel.For the convenience of maintenance,bend

     the pipe down (once) and then connect pipe to the right or left.

(5) In the case of bottom connection,join the pipe with accessory pipe through the holes in the base plate

     of the outdoor unit,and connect pipe the left or right or the back.
