R-410A SEALED SYSTEM REPAIRS
Sealed System Method of Charging/ Repairs
BURN HAZARD
Proper safety procedures must be followed,
and proper protective clothing must be worn
when working with a torch.
Failure to follow these procedures could
result in moderate or serious injury.
WARNING
FREEZE HAZARD
Proper safety procedures must be followed,
and proper protective clothing must be worn
when working with liquid refrigerant.
Failure to follow these procedures could
result in minor to moderate injury.
CAUTION
The refrigerant cycle is critically charged. The only acceptable method for charging the sealed system is the
Weighed in Charge Method.
The weighed in method should always be used whenever a charge is removed from a unit such as for a leak
repair, compressor replacement, or when there is no refrigerant charge left in the unit. To charge by this method,
requires the following steps:
1. Install a piercing valve to remove refrigerant from the sealed system. (Piercing valve must be removed from
the system before recharging.)
2. Recover Refrigerant in accordance with EPA regulations.
3. Install a process tube to sealed system.
4. Make necessary repairs to system.
5. Evacuate system to 200 microns or less.
6. Weigh in refrigerant with the property quantity of R-410A refrigerant.
7. Start unit, and verify performance.
8. Crimp the process tube and solder the end shut.
