Installation of refrigeration
connections
Bend the pipes into position and make holes
for them through the floor 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 ( fig. 19 ).
Observe the maximum and minimum distances
between the hydraulic unit and the outdoor unit
( fig. 19, page 24 ); 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 5 m.
The appliance's warranty will be void if it is operated
with refrigeration connections less than 5 m long
(tol/- 10%).
If the refrigeration connections are exposed to
weathering or UV radiation and the insulation is not
resistant, protection must be provided.
