#### Refrigerant Lines and Locations

(1) | Discharge Hose
(2) | Compressor Hose Assembly
(3) | Condenser Tube
(4) | Evaporator Tube Extension

• | All metal tubing lines should be free of dents or kinks to prevent loss of system capacity due to line restriction.

• | All flexible hose lines should never be bent to a radius of less than four times the diameter of the hose.

• | Unprotected flexible hose lines should never be allowed to come within a distance of 64 mm (2.5 in) of the exhaust manifold, 30 mm (1.2 in) for protected hoses.

• | Flexible hose lines should be inspected regularly for leaks or brittleness and replaced with new lines if deterioration or leaking is found.

• | When disconnecting any fitting in the refrigeration system, the system must first be discharged of all refrigerant. Refer to Refrigerant Recovery and Recharging .

• | Once a refrigerant line is opened to the atmosphere, it must be capped immediately to prevent moisture intrusion.

• | The use of the proper wrenches when making connection on O-ring fittings is important. The opposing fitting must be counter-held to prevent distortion of the lines and/or fittings.

• | Tighten all tubing connections to the specified torque. Too little or too much torques can result in loose or deformed seals. Either condition can result in a refrigerant leak. Refer to Fastener Tightening Specifications .
