7.5 Quick couplings
Connect the evaporator hoses to the condenser unit hoses via quick coupling: rst
connect the pair of capillary hose joints by rotang only the nut present on the female
joint. Connect the second pair of joints remembering to rotate only the nut on the
female joint. Do not dispose of the protecve covers. If you need to re-posion the
system, connecons can be reopened without leakage of refrigerant. In this case,
immediately screw on protecve covers to prevent dust from deposing on joints. Units
can be provided with two types of "X" or "O" quick couplings, shown in the following
gures.
Figure 9: "X" quick coupling type
"X" joint connecon:
1. Remove covers.
2. Check that the gasket seal on the male joint is lubricated with system uid.
3. Move the female joint and ghten the rotang nut on the male joint.
4. Tighten the union of the two parts to the appropriate torque listed using
appropriately sized spanners (in the hexagonal body of the joint and the unit
nut) unl the two sides are connected to the boom or unl you feel denite
resistance.
