Installation of fall-prevention fitting metal

Installation procedures

Installation of fall-prevention fitting metal:

Fix the fitting metal to the wall by screws so that there is no clearance between them. With the unit set up vertically, fix the fitting metal to the unit with screws while making an adjustment at the long portion of the hole so that there is no clearance between the upper surface and the fitting metal.

Installation of L-shaped metal

Fix to the unit by screws so that there is no clearance between the fitting metal and the unit.

After confirming that the unit has been set up vertically to the floor, fix it to the floor by bolt.

Piping connection

1.Connecting method

Apply refrigerant oil at half union and flare nut.

To bend a pipe, give the roundness as large as possible not to crash the pipe.

When connecting pipe, hold the pipe centre to centre then screw nut on by hand,refer to Fig.

Be careful not to let sundries, such as sands enter the pipe.

Forced fastening without centering may damage the threads and cause a gas leakage.
