Hello again.

You will not get a charging cylinder for R410a as they were intended for single composition gases only.

The procedure to use a charging cylinder is.....
a. Rotating scale adjusts charge weight for ambient temperature - set scale to pressure on gauge.

1. Evacuate the the charging cylinder.
2. Connect refrigerant bottle to the charging cylinder.
3. Let refrigerant into charging cylinder and using the scale on the cylinder measure the required charge weight into it.
4. Evacuate system to be charged.
5. Disconnect bottle and connect charging cylinder to system to be charged.
6. Open valves to start charging, turn on heater element of charger.
7. Monitor charging scale/pressure to measure in the correct charge.
