Dot Recovery Cylinder Safety - Bacharach High Performance Oilless Commercial Refrigerant Recovery Unit User Manual

DOT Recovery Cylinder Safety

WARNING!
Ensure that you are using the proper DOT recovery cylinder for the refrigerant that you are
recovering. R-410A is capable of pressures exceeding 600 psi.
Typical DOT recovery cylinders are rated at 350 psi with a pressure relief set at 550 psi.
These cylinders should not be used with R-410A! Only cylinders rated at 400 psi with a
pressure relief set at 600 psi should be used to recover R-410A. Failure to use the proper
cylinder can be extremely dangerous.
If your STINGER is equipped with the optional 80% tank full shutoff cord, connect this cord to
a DOT recovery cylinder's float switch. This cord connection will automatically shut OFF the
STINGER when the recovery cylinder reaches 80% of its liquid-full limit. It is recommended
that you use this cord for added safety.
If your STINGER is not equipped with an 80% tank full shutoff cord, or if you are using a
recovery cylinder that does not have a float switch, then you must use a scale to prevent
overfilling the cylinder.
Note: If the 80% tank full shutoff cord is present, but not being used, then a shorting cap
must be installed on the shutoff cord in order for the STINGER to operate.
Bacharach uses and recommends the Air Conditioning & Refrigeration Institute's (ARI)
Guideline K for the safe filling and handling of used refrigerant. This Publication is available
from ARI at http://www.ari.org.
The following information provides the safe fill weights for used refrigerant based on the size
of the container and is in accordance with Guideline K:
