Basic System (HVAC): Removal & Installation Mazda MX-5 NB рестайлинг

Cooling Unit Installation Note

1. When installing a new cooling unit, and DENSO OIL9 compressor oil into the refrigeration cycle. Supplemental amount (approximate quantity) 40 ml {40 cc, 1.4 fl oz}

A/C Compressor Installation Note

1. Remove the following amount of compressor oil from the new A/C compressor replacing the A/C compressor. Compressor oil to the removed (approximate quantity) = 150 ml {150 cc, 5.07 fl oz} - [compressor oil from old A/C compressor + 15 ml {15 cc, 1.5 fl oz}]

Condenser Installation Note

1. When installing a new condenser, and DENSO OIL9 compressor oil into the refrigeration cycle. Supplemental amount {approximate quantity) 30 ml {30 cc, 1.0 fl oz}

Scheme 61

Scheme 62

1. Discharge the refrigerant from the system. (See «REFRIGERANT CHARGING»(ref-194459-S17937427082005092800000) .)
2. Disconnect the negative battery cable.
3. Remove the under cover. CAUTION: If moisture of foreign material enters the refrigeration cycle, cooling ability will be lowered and abnormal noise will occur. Always immediately plug all open fittings after removing any refrigeration cycle parts to keep moisture or foreign material out of the cycle. To prevent the pipe from breaking, loosen the joint by using two open-end wrenches.
4. Remove in the order indicated in the figure.
5. Install in the reverse order of removal.
6. Perform the refrigerant system performance test. (See «REFRIGERANT SYSTEM PERFORMANCE TEST»(ref-194459-S36559232582005092800000) .)

Refrigerant Lines Removal Note

Note. There are two types of SSTs: 49 N061 001 (high-pressure) and 49 N061 002 (low-pressure).

Scheme 63

Scheme 64

Scheme 65

1. Set the SST into the clamp with the arrow mark on the clamp facing the SST.
2. Push the SST with your thumb until the clamp clicks. CAUTION: If the SST is pushed with excessive force, the clamp will deform. Be careful when pushing the SST into the clamp.
3. Pull up the stopper, then pull the SST from the pipe.
4. Remove the SST from the clamp. CAUTION: Be careful not to bend the SST needles when performing a clamp removal. If the needles are bent, the clamp can not be unlocked.

Refrigerant Lines Installation Note

1. Apply compressor oil to the O-rings and connect the joints.
2. When installing a new cooler hose or pipe and DENSO OIL9 compressor oil into the refrigeration cycle. Supplemental amount (approximate quantity) 10 ml {10 cc, 0.3 fl 0z}
3. Tighten the joints. Tighten the nut or bolt of the joint by hand. Tighten the joint to the specified torque. If it is a nut joint, tighten the nut using a spanner and torque wrench.
