... CAUTION ...
CONSULT THE CHARGING CYLINDER OR WEIGHT SCALE INSTRUCTIONS FOR
SAFE OPERATING PROCEDURES.
CARELESS OPERATION MAY RESULT IN A DANGEROUS CONDITION CAUSED BY
OVERFILLING THE CHARGING CYLINDER OR AUXILIARY TANK.
DO NOT EXCEED THE MAXIMUM RATED PRESSURE OF A CHARGING CYLINDER
OR AUXILIARY TANK.
CAREFULLY MONITOR THE LIQUID LEVEL OF REFRIGERANT IN THE CHARGING
CYLINDER OR WEIGHT OF AUXILIARY TANK DURING A FILL PROCEDURE.
OVERFILLED CHARGING CYLINDERS OR AUXILIARY TANKS MAY DAMAGE THE
RR750X COMPRESSOR DURING THE MOMENTARY PRESSURE DIFFERENTIAL
PROCEDURE AND VOID THE WARRANTY!
The Charging Cylinder or Auxiliary Tank can now be filled and used to charge the A/C System
according to the Manufacturer’s instructions.
A pressure differential is required to encourage flow of refrigerant into the A/C System.
Some Charging Cylinders have a heating element for the purpose of creating this differential in
pressures.
Mild heating of the Auxiliary Tank will develop this pressure differential. Immersion in warm
water is the least risky method.
