3.1 - REFRIGERANT CONNECTIONS
To define the refrigerant connection lines between the internal and external units, refer to the table below.
Sherpa S3 E
4-6 kW 8-10-12-14-16 kW
Maximum length of the connection pipes (m) 30 30
Minimum length of the connection pipes (m) 2 2
Elevation difference limit between the two units if the external
unit is positioned higher (m)
20 20
Elevation difference limit between the two units if the external
unit is positioned lower (m)
15 15
Additional load of refrigerant per metre beyond 15 metres of
pipes (g/m)
20 38
Exclusively use pipes with diameters which respect the required dimensions.
The maximum length of the connection lines to the internal unit MUST be compliant with the table
in paragraph “3.1” topping up the load of R32 as envisaged (see par.3.1.2). Do not install the units
beyond the maximum allowed difference in level between internal and external unit.
Complete the refrigerant circuit by connecting the internal unit with the external unit by means of the insulated
copper pipes.
• Exclusively use insulated copper pipes specific for refrigeration;
they must be clean and sealed at their ends.
• For models SHERPA S3 E (4-6 kW) , use a reducer for the liquid
pipe from 3/8” to 1/4”.
The refrigerant connections of the internal unit are behind the electric
panel, the ones of the external units are on the right side and, in order
to access them, it is necessary to remove the guard. (fig.9-10a-10b)
U1.
Internal unit 5/8” gas line.
U2.
Internal unit 3/8” liquid line.
U3.
External unit 5/8” gas line valve.
U4.
1/4” liquid line valve for U.E. SHERPA S3 E (4-6 kW); 3/8” for U.E. SHERPA S3 E (8-10-12-14-16 kW).
• Identify the path of the pipes in order to reduce length and bends of the pipes as much as possible and
to obtain maximum performance of the system.
• Insert the refrigerant lines in a cable gland duct (possibly with internal separator) of the appropriate
dimensions fixed to the wall through which the pipes and the electric cables will pass.
• Cut the pipe sections abounding of approximately 3-4 cm on length.
Cut exclusively using a wheel pipe cutter while tightening at small intervals in
order not to crush the pipe.
• Remove possible burrs using the specific tool.
• Insert the fixing nut in the pipe before flaring (fig.11).
• Flare the ends of the pipes using the specific tool flawlessly without breakages, cracks or cleavage
(fig.11).
• Manually screw the nut of the pipe on the coupling thread.
