Basic instructions

Recover refrigerant from system

Carry out vacuum of system

Access vacuum loss to determine severity of leak.

If severe leak connect OFN to manifold set and increase pressure to maximum of 10 bar, leak may be heard or the use of bubble solution may be used to locate leak

If minor leak connect Loktrace to manifold set and increase pressure to maximum 10 bar. Use detector to locate leak. Bubble solution can be used to confirm location of leak

Note:- A system can hold a vacuum but a leak can still be present.
