Installing
Installation is the reverse of removal, noting the following:
-
Replace O-ring seals - 4 - and - 5 -.
-
Make sure that O-ring seals - 4 - and - 5 - are properly seated on connecting pipes to evaporator.
‹› Expansion valve is available in different versions (same housing but a different control characteristic), therefore ensure the exact allocation.
‹› Coat O-ring seals lightly with refrigerant oil before installing => [ O-Ring Seals for Refrigerant Circuit ] See: Service and Repair/Removal and
Replacement/O-Ring Seals for Refrigerant Circuit.
‹› If heat insulation is applied on the expansion valve (not intended at this time), a reduction in performance may arise when heat insulation is
missing or not installed correctly (modifies the set control characteristic by radiating heat).
‹› Retaining plate - 3 - is installed on connection pipes, check for proper fit when installing expansion valve.
-
Place expansion valve - 2 - on to connections on evaporator.
-
Install bolts - 1 - (tightening torque 10 Nm).
