ELIMINATION OF ACME FITTINGS AND FILTER CHANGES

When installing the WR86X96 filter drier, add

an additional 1/2 ounce to the quantity

stated on the name plate to compensate for

the additional volume of the filter.

The charging valve (WJ56X61) should be

used at the compressor process tube for

charging the system.

Effective in 2004, ACME fittings are no longer

required when making a repair on R134a

refrigerant systems.

Improvements in refrigerant oil and system

design over the years has shown the danger

of cross-contamination from using the same

hoses to be minimal. All fittings for refrigera-

tion repair will be converted to 1/4" SAE as

inventory of ACME fittings is depleted.

Although R134a and R12 will share a common

fitting size, care must still be taken to prevent

cross-contamination of recovery cylinders.

Label charging and recovery cylinders appro-

priately and follow all refrigeration and safety

procedures.

A new “drier only” design is available for most

refrigeration sealed system repairs.

When installing the WR86X93 drier, recharge

the system with the exact refrigerant charge

stated on the name plate.

The installation of only a drier (WR86X93) is

approved for all sealed system repairs except

in the following situations:

1. Replacing a rotary compressor

2. Compressor burn-out

3. When known contaminates have entered

the system.

For these repairs, the installation of a filter

drier (WR86X96) with extra filtering capacity

is required.
