m WARNING: Also read the information per-
taining to recovery tanks, previously listed under
Safety Information and Operating Guidelines.
m CAUTION: NEVER use a standard disposable
30 lb. (the type of container in which virgin refrig-
erant is sold) to recover refrigerant.
Use ONLY authorized refillable refrigerant tanks.
Federal regulations require refrigerant to be trans-
ported only in containers meeting DOT specs.
4BA or 4BW.
mWARNING: DO NOT: Exceed the working pres-
sure of each cylinder. Recovery cylinders are
designed for different pressures. Your ProVax
is not supplied with a recovery tank, it requires
the use of tanks with a minimum of 350 psi
working pressure and Promax strongly recom-
mends the use of 400 psi tanks.
NOTE: The use of a 400 psi tank is mandatory
when recovering R-410A.
See Promax Recovery Tanks under Parts and
Accessories section on Page 17.
Tanks and filters should be designated for one
refrigerant only. Before using a tank previously
used for another refrigerant, completely empty
the tank, evacuate it and purge the tank using dry
nitrogen, and then re-evacuate it.
Always store refrigerant containers in a cool dry
place.
Do not mix refrigerants in a system, a tank or any
where else. Each type of refrigerant must have its
own tank, filter, etc.
Storage cylinders sometimes have valves that are
not properly seated when manufactured. Keeping
caps on these valves will guard against refriger-
ant leakage.
Safety codes recommend that closed tanks not
be filled over 80% of volume with liquid. The
remaining 20% is called head pressure room.

m WARNING! NEVER TRANSPORT AN OVERFILLED CYLINDER
Refrigerant expands when it gets warm and may cause a tank to explode if overfilled.
