TECH TIP #27
A quick guide to -
Refrigerant Cylinder Storage in Service
Vehicles
Æ Store and transport refrigerant cylinders in an upright position
out of direct sunlight
Æ Place sealing cap on outlet valve to prevent thread damage, seal
out contaminants and prevent refrigerant leakage
Æ Never allow cylinder temperature to exceed 130º F (54.4º C).
Temperatures above 130º F could result in excessive cylinder
pressure and damage to the container’s physical integrity resulting
in a serious accident.
Æ Keep refrigerant cylinders in original packaged carton thus
keeping them from dents, punctures and scratches.
Æ Visually inspect cylinders to ensure they are in safe condition.
Æ Cylinders should be properly secured at all times to prevent
tipping, falling or rolling around. They may be attached to a truck
wall, cylinder truck, cylinder rack, or post.
Æ R-410A cylinders have already been redesigned for higher pressure
during normal transportation, use and handling.
