4. Connect the DrainKat to the parent cylinder using the FA-03 adaptor.
(See illustrations #1 & 2)
WARNING: Colder cylinders accept more CO
2
while filling.
Cylinders that are cold or that have been pre-chilled before being filled
must be weighed to confirm they are not overfilled.
5. With cylinders hand tightened together, open the DrainKat, then slowly open the
parent cylinder allowing pressure to equalize.
6. When flow stops, close both cylinder valves, and disconnect the cylinders by
unscrewing the adaptor.
7. There will be a slight release of gas between the two cylinders upon disconnecting.
8. Re-weigh the DrainKat, and subtract the tare weight. This is the contents weight.
9. Check the contents against the rated capacity of the Drain Kat usually stamped
into the neck of the cylinder. If the cylinder is overfilled, release the excess
contents immediately.
WARNING: OVERFILLED CYLINDERS ARE DANGEROUS!
Always check contents weight on an accurate scale.
NITROGEN FILLING:
1. Disconnect hose and unscrew regulator from the DrainKat.
2. Connect FA-03 and FA-01 adaptors onto the DrainKat cylinder valve.
(See illustration #3)
3. Connect the DrainKat onto the larger nitrogen cylinder (mother cylinder).
4. Open the DrainKat, then slowly open the parent cylinder allowing pressure to
equalize.
5. Completely close both cylinder valves, and disconnect the cylinders by
unscrewing the adaptors.
6. There will be a slight release of gas between the two cylinders upon disconnecting.
7. Check for continuous leaks.
CAUTION: This equalizing transfill does not overfill the DrainKat when using a
standard 2015 psi 40 Cu.Ft. or 80 Cu.Ft. parent cylinder. Larger capacity or higher
pressure parent cylinders require the use of a system to prevent pressures over
1800 psi from entering the DrainKat.
