Refrigerant connections

Refer to the indoor unit manual for refrigerant con-nections

Prerequisites

  • This section is intended exclusively for the Installer.
  • Refer to the Technical data chapter for details.
  • Follow the safety instructions in the “About R-32 refrige-rant” chapter on page 7.
  • The refrigerant piping and its components must be desi-gned by a qualified technician who must work according to the rules of good practice and national regulations.
  • This unit is a subset and must be combined with another unit in order to function.
  • Comply with the PED Directive and the national regula-tions implementing the PED Directive.
  • Consider the activation of any additional safety devices.
  • Check operation of the safety devices.
  • Indicate on the serial number label the total amount of refrigerant.
  • Issue the declaration of conformity.
  • Inform the user of the need to carry out regular checks.
  • Only use copper piping specific for R32 refrigeration.
  • An incorrect sizing can cause damage to the compressor or variations in the cooling performance.
  • Piping should be cleaned and sealed at the ends.
  • Clean with nitrogen or dry air before connecting the piping to the two units.
  • Do not use piping with a different diameter.
  • Do not use used refrigerant piping, the flare connection seal is not ensured.
  • Do not make connections using hydraulic piping.
  • Do not weld with the presence of refrigerant in the piping.

Ensure that:

  • the piping route is as straight as possible, limiting the presence of bends, in order to achieve maximum system efficiency properly insulate piping
  • when installing shut-off devices (solenoid valves, taps, etc.), attention is paid to the possibility of installing refri-gerant traps, i.e. closed upstream and downstream areas where the refrigerant cannot expand freely
    in this situation, the expansion of the trapped gas could cause an explosion in the refrigerant piping if the temperature rises (exposure to sun, piping close to heat sources, etc.). Consider installing a pressure relief valve, especially in the liquid piping which is potentially exposed to this risk.

Avoid therefore:

  •  bends with too small a radius
  •  crushing piping
  •  passing through particularly silent environments.

Connection

  • The indoor unit and the outdoor unit must be connected by refrigerant piping suitable for the refrigerant used and cove-red with thermal insulation.
  • The way the piping is installed can influence the noise level of the system:
  •  use anchor brackets to support the piping (the weight must not burden the units)
  •  the brackets must allow for thermal expansion of the piping
  •  place vibration-damping material between the brackets and piping to prevent the transmission of vibrations Piping must be clean.

CLIVeT-MiSAN-YEE-External-Unit-FIG-39

  • If installation of the piping is not completed by the next day or for a long period of time, braze the ends of the pipes and fill with anhydrous nitrogen through a Schra-der valve access fitting to prevent moisture and particle contamination.

Maximum distances
Refrigerant piping.

CLIVeT-MiSAN-YEE-External-Unit-FIG-40

  • Equivalent length of the lines (metres) = Actual length (metres) + (Q.ty of bends x K)
  • Consider K=0.3 m for wide radius 90° bends. Consider K=0.5 m for standard 90° elbow bends.

Piping size

  • Before connecting the piping to the two units, clean with nitrogen or dry air.

CLIVeT-MiSAN-YEE-External-Unit-FIG-41
