greatly reduced the refrigeration capacity of
the entire system.
2. The flexible hose lines should never be

3. Use only sealed lines from parts stock.
4. When disconnecting any fitting in the

be discharged of all refrigerant. However,
proceed very cautiously, regardless of
gauge readings. If liquid refrigerant happens
to be in the line, disconnect fittings very
slowly, keeping face and hands away so
that no injury can occur. If pressure is
noticed when fitting is loosened, allow it to
bleed off very slowly.
