Cooler Connection - Olimpia splendid Unico twin Mode D'emploi Et D'entretien

3 - COOLER CONNECTION

open the casing on the side for access to the connectors.
• Do not make the connections using normal hydraulic pipes that could contain
residues of flashing, dirt or water and that could damage the parts inside the
unit and interfere with proper operation.
• Use only special copper pipes for cooling, that are supplied clean and sealed
at the ends.
After cutting the proper lengths, seal the ends immediately on the roll and cut piece.
Only use pipes with the a diameter suitable for the dimensions described in the technical data
sheets.
Pipes for refrigeration with preinsulation can also be used.
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/ (Kxm2)
- minimum thickness: 6 mm (for liquids) and 9 mm (for gases).
- Plan the route of the pipeline so as to reduce the length and number of bends as much as possible for
best performance of the system.
the maximum length of the lines connecting the outside unit to the inside unit is 10 m in both directions.
Maximum height different between two units +/- 5 m.
- fasten a cable raceway to the wall (possibly with internal partitioning) of suitable size for the pipes and
electric wires to pass through.
- Cut the sections of pipe leaving an extra 3-4 cm on the ends.
Use a wheel pipe cutter only to cut the pipes 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
- Bind any joints in the sheath securely with insulating tape.
- Before flaring the pipe ends, insert the fastening nut.
- flare the pipe ends using the special tool. take care not to break, crack or split the pipe.
- lubricate the thread of the coupling onlY with refrigerant oil.
- Use your hands and then a wrench screw the nut of the hose on the coupling thread.
Tighten using a wrench to hold the threaded part of the connector, so as to avoid twisting the pipe, and a
dynamometric wrench on the nut calibrated with the following values depending on the size of
the pipe:
- 14-18 nxm (1.4-1.8 kgxm) for pipe diameter ø 6-6.4 mm
- 33-40 nxm (3.3-4.0 kgxm) for pipe diameter ø 9.5-10 mm
- 50-60 nxm (5.0-6.0 kgxm) for pipe diameter ø 12-12.7 mm.
