WARNING
ICON 26 44
Wear protective goggles and nonleather gloves when servicing air conditioner or
injury may result.
CAUTION
Dry nitrogen gas is recommended for purging. A pressure regulator is required to
regulate gas pressure between 0 and 200 psi (0 and 1,379 kPa). Commercial
cylinders of nitrogen contain pressures in excess of 2000 psi (13,790 kPa). This
pressure must be reduced to 200 psi (1,379 kPa) for purging or damage to
equipment may result.
