Lower charge
requirements
Because the molecular structure of HC Refrigerants is considerably larger
than that of existing synthetic alternatives, less of the refrigerant
is required to charge a system. This not only reduces system pressures,
but also helps prevent refrigerant leakage over time.
For example:
• HC-12a®
requires 34% of the
CFC R12 charge by weight
• HC-12a® requires 40%
of the
HFC R134a charge by weight
• HC-22a® requires 40%
of the
HCFC R22 charge by weight
• HC-502a® requires 40%
of the
CFC R502 charge by weight |

HC-502a®
Charging Instructions
1. Operate the system for 24-hours and record temperature and pressures
of unit operation. Inspect the system, make any required repairs and
perform routine maintenance before charging with HC Refrigerant.
2. Existing refrigerants may need to be removed and reclaimed by qualified
personnel. The weight of the recovered refrigerant should be recorded.
Local regulations may vary by region and the technician should be
aware of all applicable requirements.
3. Perform a system vacuum and confirm that system does not leak.
4. Connect liquid valve from cylinder to gauge manifold. Make sure
the charging lines are clean and purged.
5. Connect manifold equipment to the low-pressure side of system.
Ensure all components have been properly grounded. When charging a
large system, the charging equipment, hoses, and system must be grounded
to stop a build-up of static electricity.
6. When all connections have been made, insure there are no leaks
before continuing.
7. Partially closing the suction service valve will reduce the flow
from the regular evaporators and speed the transfer of refrigerant
from the charging cylinder to the system.
8. Using the weight of the recovered refrigerant, or the system specifications,
the weight of HC-22a® or HC-502a® required will be approximately
40-42% of the weight of the recovered CFC or HCFC refrigerant.
9. After verifying that pressures and temperatures are correct, remove
the charging equipment and attach the HC System label (provided) to
the system in a prominent area.
Easily replaces harmful refrigerants
HC Refrigerants are designed to replace many environmentally harmful
refrigerants currently in use.
• HC-12a® is designed
as a drop-in replacement for ozone-depleting CFC R12 and global-warming
HFC R134a refrigerant.
• HC-22a® is designed as
a drop-in replacement for ozone-depleting HCFC R22 refrigerant.
• HC-502a® is designed
as a drop-in replacement for ozone-depleting CFC R502 refrigerant. |
