General Description
Illustration Tools and Equipment
Wrench
Va r i o u s WRENCHES will be required to service any A/C system. A 7 to
40 N·m (0.7 to 4.1 kgf-m, 5 to 30 ft-lb) torque wrench and various crow-
foot wrenches will be needed. Open end or flare nut wrenches will be
needed for back-up on the tube and hose fittings.
Applicator bottle
A small APPLICATOR BOTTLE is recommended to apply refrigerant
oil to the various parts. They can be available at a hardware or drug
store.
Manifold gauge set
A MANIFOLD GAUGE SET (with hoses) can be available at from
either a refrigerant supplier or an automotive equipment supplier.
Refrigerant recovery system
A REFRIGERANT RECOVERY SYSTEM is used for the recovery and
reuse of A/C system refrigerant after contaminants and moisture have
been removed from the refrigerant.
