Refrigerant Temporary Recovery Procedure
¾ If direct venng is not possible due to the appliance
locaon or other reason, the refrigerant must be
captured. The captured refrigerant should be vented
outdoors before leaving the premises. Do not travel with
any reclaimed R600A Sealed System Refrigerant. Venng
is the Preferred Method.
¾ Connect one end of the Recovery Hose to the quick
disconnect fitting on the approvd Recovery Vessel.
¾ Connect the other end of the Recovery Hose to the quick
disconnect fitting on the piercing pliers or shrader valve.
¾ If the compressor is functional, run the compressor to
speed the venting process.
¾ Allow the refrigerant to vent into the approved Recovery
Vessel for 40 minutes.
¾ Monitor the hose to ensure it remains kink free
¾ After the sealed system is fully vented, disconnect the
Recovery Hose from the quick disconnect fitting.
¾ Purge the Recovery Hose with the leak detection trace gas
mixture to remove residual R600a.
¾ Immediately remove the approved Recovery Vessel
to a suitable outdoor location and vent the bag to
atmosphere, removing all R600a refrigerant.

Calibrated in Accordance With Manufacturer Specifications.
Sealed System Evacuating Procedure
R600a is an extremely ecient refrigerant. This high eciency
means refrigerators using R600a refrigerant use a much
smaller charge size than a comparable refrigerator with CFC
refrigerant.
¾ This small charge size increases the signicance of any error
in quanty charged. To obtain the precise charge required
use Lokring’s LOKBOX Charging Facility. This facility has a
digital scale with a high degree of accuracy, in addion to
the other required hoses and connecons.
¾ Condensaon forming on the refrigerant bole will add
weight to the bole, resulng in charging errors.
¾ Open the case and remove the LP (vac) combinaon gauge
manifold and set aside.
¾ Thread the closed extracon valve into the holder with the
the bole R600a cartridge.
