INTRODUCTION
This machine is ETL Laboratories approved, in compliance with SAE J2843. We are dedicated to solving
the issues surrounding the safe containment and proper management of refrigerants. Your new machine
incorporates the latest technology and state of the art features to aid you in servicing R1234yf air conditioning
and refrigeration systems.
NOTICE:
The SAE J2843 standard has, by design made recycling machines more complex than previous models
that some End Users might be familiar with. Some noticeable changes that the End User should expect from ALL
new recycling machines are the following:
1. RECOVERY TIME:
The average recovery time is approximately 30 minutes. This time is necessary to
meet the SAE J2843 standard which requires that the machine recovers at least 95% of the AC system
refrigerant and cleans the refrigerant to a minimum of 95% purity.
2. HOT WEATHER:
As the ambient temperature approaches 100°F, some End Users have experienced
an increase in recovery time. This is due to the natural response of R1234yf when its temperature is
elevated. R1234yf has difficulty transforming from a gas into a liquid state at elevated temperatures. The
transformation into liquid is necessary for the machine to complete the recovery process. The End User
might notice the same effect when performing a TANK CHARGING operation. The COMMANDER series
includes a color touch screen tablet that may experience a slower processing time in extreme heat and
humidity. Avoid exposing the machine to dramatic changes in temperature or humidity.
3. COLD WEATHER:
As the ambient temperature approaches 50°F, some End Users have experienced
an increase in recovery time. This is due to the natural response of R1234yf when its temperature is
lowered. R1234yf has difficulty transforming from a liquid into a vapor state at reduced temperatures. The
transformation into vapor is necessary for the machine to complete the distilling process. The End User
might notice the same effect when performing a TANK CHARGING operation. The COMMANDER series
includes a color touch screen tablet that may experience a slower processing time in extreme cold and
humidity. Avoid exposing the machine to dramatic changes in temperature or humidity.
4. SUN GLARE:
Because of the way the COMMANDER color touch screen is constructed the user may
experience mirror-like screen reflectivity or screen images that are too dim to read in direct sunlight.
Whenever possible keep the color touch screen out of direct sunlight.
SAFETY SUMMARY

SAFETY INFORMATION
Every craftsman respects the tools with which they work. They know that the tools represent years of constantly
improved designs and developments. The true craftsman also knows that tools are dangerous if misused or
abused. To reduce risk of discomfort, illness, or even death, read, understand, and follow the following safety
instructions. In addition, make certain that anyone else that uses this equipment understands and follows these
safety instructions as well.
READ ALL SAFETY INFORMATION CAREFULLY before attempting to install, operate, or service this equipment.
Failure to comply with these instructions could result in personal injury and/or property damage.
RETAIN THE FOLLOWING SAFETY INFORMATION FOR FUTURE REFERENCE.
Published standards on safety are available and are listed at the end of this section under ADDITIONAL SAFETY
INFORMATION.
The National Electrical Code, Occupational Safety and Health Act regulations, local industrial codes and local
inspection requirements also provide a basis for equipment installation, use, and service.
The following safety alert symbols identify important safety messages in this manual.
When you see one of the symbols shown here, be alert to the possibility of personal injury and carefully read the
message that follows.
Never fill the tank to more than 80% of maximum capacity as this will not leave an expansion chamber for
