The refrigerant should be charge from the service port on the outdoor unit's low
pressure valve.
Piping connections must be outdoors.
a. Fasten a cable raceway to the wall (possibly with internal partitioning) of suitable size for the pipes and
electric wires to pass through.
b. Cut the sections of pipe leaving an extra 3÷4 cm on the ends.
Use a wheel pipe cutter only to cut the pipes (fig. 18) clamping it in short lengths
so as not to crush the pipe.
NEVER USE A NORMAL HANDSAW,
scraps could fall inside the pipe and enter the circuitry of the system, damaging
the parts severely (fig. 19a).
c. Remove possible burrs with the special tool.
Immediately after cutting and deburring the pipes, seal the ends with insulating
tape.
d. If you do not use preinsulated pipes, they must be insulated as follows:
• material: polyurethane foam with closed cells
• max. coefficient of transmission: 0,45 W/ (K x m
• minimum thickness: 6 mm (for liquid pipes)
• minimum thickness: 9 mm (for gas pipes)
Do not place both pipes in the same sheath, as this would jeopardize the proper
operation of the system (fig. 19b).
e. Bind any joints in the sheath securely with insulating tape.
f. Insert the fixing nut into the pipe before performing flaring (figure 20).
g. Flare the pipe ends using the special tool. Take care not to break, crack or split the pipe (fig. 20).
h. Lubricate the connecting thread with oil for coolant.
DO NOT USE ANY OTHER TYPE OF LUBRICANT
i. Screw the pipe nut manually on
the connecting thread.
l. Tighten the nut definitively using
a wrench to hold the threaded
part of the attachment still (to
prevent deformations), and a
dynamometeric wrench on the
nut (figure 21).
Calibrate the dynamometric
wrench to the value suitable for
the pipe dimensions.
