Mastercool 69788-A R134a RECOVERY_RECYCLE_RECHARGE - Manual (Page 4)

INTRODUCTION
This machine is ETL Laboratories approved, in compliance with SAE J2788. 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 R134a air conditioning and refrigeration systems.
NOTICE:
The SAE J2788 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 J2788 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 R134a when its temperature is elevated. R134a 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.
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 R134a when its temperature is lowered. R134a 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.
SAFETY SUMMARY
The following safety information is provided as guidelines to help you operate your new system under the safest possible conditions. Any equipment
that uses chemicals can be potentially dangerous to use when safety or safe handling instructions are not known or not followed. The following
safety instructions are to provide the user with the information necessary for safe use and operation. Please read and retain these instructions for
the continued safe use of your service system.
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 absorbing any pressure increases.
ELECTRICAL SHOCK HAZARDS
• To reduce the risk of electric shock, unplug the power supply cord from the outlet before attempting any maintenance or cleaning. Turning off
controls will not reduce this risk.
• Do not operate the machine with a damaged cord or plug — replace the cord or plug immediately. To reduce the risk of damage to electric plug
and cord, disconnect the power cord by pulling on the plug rather than the cord.
An extension cord should not be used unless absolutely necessary. Use of an improper extension cord could result in a risk of fire, electric shock
and component damage. If extension cord must be used, make sure:
a. That pins on plug of extension cord are the same number, size, and shape as those on plug on recycler.
b. That extension cord is properly wired and in good electrical condition; and
c. That the wire size is large enough for the length of cord as specified below:
Length of cord in feet: 25 50 100 150
AWG size of cord: 16 12 10 8
