Cutting/Flaring the pipes Make sure that you have the required tools available. (pipe cutter, reamer, flaring tool and pipe holder) If you wish to shorten the pipes, cut it with a pipe cutter, taking care to ensure that the cut edge remains at a 90° angle with the side of the pipe. Refer to the illustrations below for examples of edges cut correctly and incorrectly.
Using stop valve To Open the Stop Valve Open the cap and turn the stop valve counterclockwise by using a hexagonal wrench. Service port Turn it until the axis is stopped. Note Do not apply excessive force to the stop valve and always use ...
Adding refrigerant The outdoor unit is loaded with sufficient refrigerant for the standard piping. Thus, refrigerant must be added if the piping is lengthened. This operation can only be performed by a qualified refrigeration specialist. For quantity of adding refrigerant, refer to page 19. Check that the stop valve is closed entirely.

The quantity of additional refrigerant is variable according to the installation situation. Thus, make sure the outdoor unit situation before adding refrigerant. This operation can only be performed by a qualified refrigeration specialist.

If you install a transmitter to an outdoor unit, every indoor unit which is connected to an outdoor unit can be controlled simultaneously. Each outdoor unit connected to the same centralized controller has its own transmitter. UH105/140CAV UH070CAV1 Plate Control Low Transmitter Terminal side Transmitter Bolts spec.
Pump down Procedure Pump down will be carried out when an evaporator is replaced or when the unit is relocated in another area. Remove the cap from the low pressure side. Turn the low pressure side valve clockwise to close and connect a pressure gauge (low pressure side) to the service valve, and open the valve again.
Checking correct grounding If the power distribution circuit does not have a grounding or the grounding does not comply with specifications, an grounding electrode must be installed. The corresponding accessories are not supplied with the air conditioner. Select an grounding electrode that complies with the specifications given in the illustration.
