REFRIGERANT HANDLING AND SAFETY

Do not proceed with any aspect of a procedure if you do not fully understand the
procedure and know what result to expect. Understand that pressure exists in
refrigeration systems. Be careful.


REFRIGERANT

SEAFROST is charged with REFRIGERANT-404a. REFRIGERANT-404a is a blend of
HFC refrigerants. It is odorless. Its boiling point is -57. Degrees F. at sea level. It is
heavier than air. It's label and container color is orange.


GENERAL SAFETY THIS IS IMPORTANT. READ THIS!

R-404a is safe if handled properly. Avoid breathing vapors and prolonged skin
exposure. Avoid using in areas of open flames. The vapor is heavier than air and may
reduce oxygen available for breathing. Use with sufficient ventilation to keep exposure
below recommended limits. Do not mix with air for leak testing or use with air for
any purpose above atmospheric pressure.
Liquid R-404a will freeze skin. It's
especially dangerous to the irreparable tissues of the eyes.

--WEAR EYE PROTECTION--



Do not pressurize an empty system with R-404a without first evacuating the
system with a vacuum pump.


WARNING: DANGER NEVER OPERATE A SYSTEM WITH THE HIGH SIDE
(DISCHARGE) OPEN TO THE REFRIGERANT SUPPLY. PRESSURIZATION OF THE
REFRIGERANT SUPPLY COULD CAUSE IT TO BURST.
