Robinair 25175B REFRIGERANT RECOVERY SYSTEM - Manual (Page 7)

ƽ
Warning: Also read the information pertain-
ing to recovery tanks, previously listed under
Safety Information and Operating Guidelines.
1.CAUTION: NEVER use a standard disposable
30lb. tank (the type of container in which virgin
refrigerant 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.
4BW or 4BA.

ƽ
Warning: DO NOT: Exceed the working pres-
sure of each cylinder. Recovery cylinders are
designed for different pressures. Your 25175B is
not supplied with a recovery tank, it requires the
use of tanks with a minimum of 350 psi working
pressure and ROBINAIR strongly recommends
the use of 400 psi tanks.
NOTE: The use of a 400 psi tank is mandatory
when recovering R-410A.
See ROBINAIR Recovery Tanks under Parts and
Accessories section on Page 15.
3. 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.
3. Always store refrigerant containers in a cool dry
place.
5. Do not mix refrigerants in a system, a tank or any
where else. Each type of refrigerant must have its
own tank, filter, etc.
6. Storage cylinders sometimes have valves that are
not properly seated when manufactured. Keeping
caps on these valves will guard against refrigerant
leakage.
7. Do not exceed 80% of tank capacity. ROBINAIR
strongly recommends the use of the ADS-100
Refrigerant Scale for monitoring tank capacity.
Safety codes recommend that closed tanks not be
filled over 80% of volume with liquid. The remain-
ing 20% is called head pressure room.
8. If you expect temperatures in excess of 135° F,
contact the refrigerant supplier.
