Refrigerant Temporary Recovery Procedure
¾
If direct venting is not possible due to the appliance
location 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. Venting
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 approv
e
d 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 approv
e
d Recovery Vessel
to a suitable outdoor location and vent the bag to
atmosphere, removing all R600a refrigerant.

ATTENTION:
Ensure Refrigerant Measuring Equipment is Maintained and
Calibrated in Accordance With Manufacturer Specifications.
Sealed System Evacuating Procedure
R600a is an extremely efficient refrigerant. This high efficiency
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 significance of any error
in quantity 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 addition to
the other required hoses and connections.
¾
Condensation forming on the refrigerant bottle will add
weight to the bottle, resulting in charging errors.
¾
Open the case and remove the LP (vac) combination gauge
manifold and set aside.
¾
Thread the closed extraction valve into the holder with the
the bottle R600a cartridge.
