Installation of refrigeration connections
Bend the pipes into position and make holes
for them through the fl oor or walls either with
their protective caps in place or after brazing.
Keep the protective caps in place or ends
brazed until the appliance is commissioned.
The outdoor unit must be connected to the
hydraulic unit ONLY with brand new separately
insulated copper connections (refrigerant quality).
Maintain the same pipe diameters (fi g. 25, page 26).
Observe the maximum and minimum distances between
the hydraulic unit and the outdoor unit (fi g. 25, page 26);
the guarantee of performance and the service lifespan
of the system depend on this.
The minimum length of the refrigeration
connections for correct operation is 3 m.
The appliance's warranty will be void if it is operated
with refrigeration connections less than 3 m long
(tolerance +/- 10%).
Ensure that the refrigeration connections are protected
from physical deterioration.
