13. REFRIGERATION LINKS

13.1. PIPE LINKS TO BE CREATED ON SITE

This work must be performed by qualified personnel in accordance with the best heating and air conditioning
engineering practices (brazing, vacuum draining, filling, etc.).
² Only use refrigeration quality copper pipe.
²
Use anti-vibration collars for attaching pipe work
to the walls.
² To avoid the introduction of foreign bodies into the
pipes (dust, filings, etc.) always fit the pipes with end
caps before handling or work.
² Carefully unwind pipe coils in the opposite direction to the spirals and take care to avoid creating
folds or twists.
13.1.1. REFRIGERATION PIPE BENDING
The bending radius of the pipes should be equal to or more than 3,5 times de outside diameter
of the pipe.
Do not bend the pipes consecutively more than three times and do not make more than 12
bends over the complete length of the link.
WARNING!
Take care not to damage the refrigerating pipe links by applying too much tightening pressure.
Use a second wrench to compensate for the tightening torque.
You should always use a counter-wrench for tightening valves.

13.2. LENGTH OF COOLING PIPE

Aqu@Scop Advance Split DCI units are pre-charged at the factory for pipe lengths between 3m and 12.5m.
pipe lengths can then extended up to 25m for the outdoor units ODU1, and to 30m of other models, in accordance
with the additional refrigerant charge table (refer to the technical specifications).
maximum pipe lengths
maximum height difference
Aqu@Scop Advance Split DCI units can function correctly up to a maximum height difference of 5m between
the modules. If the difference in height exceeds 5m, a siphon must be incorporated in the gas line every 5m.
