19.9.6. Filter-vlagopoglotitelja installation

The filter located in the liquid pipeline, allows to increase time of operation of system KB between washings by coolant R-11. The filter should be established after a repeated contamination of a throttle aperture or at replacement of the compressor because of jamming of mobile details, the filter includes a grid and a thin filtering element. The grid detains large particles, and filtering element – small. Refrigerating oil is cleared of mechanical impurity by a filtering element. The filter establish in the pipeline between the condenser and the evaporator. There are two versions of the filter.

1) the Filter without a throttle, established in a high pressure zone before a throttle branch pipe. It is a preferable variant.

2) the Filter with a throttle. In this case the filter settles down in a zone of low pressure after a throttle aperture. At use of this type of the filter a throttle branch pipe dismantle.

To remove or disconnect
1. To measure length of tubes under a scrap:
The filter without a throttle – 51 mm;
The filter with a throttle – 70 mm.
2. To discharge system from a coolant.
3. To cut off the tube end at right angle by means of a trumpet cutting torch.
4. To remove a file external agnails.
5. To remove a file internal agnails. The metal shaving should not get in a tube.
The prevention

The metal shavings which have got to system KB, will lead to fast deterioration of details and a system exit out of operation.

To establish or attach

1. The switch.
2. Electric contacts of the switch and pipelines on a back cover of the compressor.
3. A negative wire of the storage battery.
4. To pump out air and to charge system.
5. Joining of the filter to aluminium pipelines: the instruction is enclosed in a bag with the tool complete set.
5а. To discharge system from a coolant.
5б. Whenever possible to choose a place установ ки the filter in a zone where it is possible использо вать additional fastenings (for example, on a wing mudguard).
5в. To cut out a site of the pipeline in length of 120 mm. To remove agnails and sawdust from the pipeline ends.
5г. To insert the tube end into an union aperture against the stop.
5д. To tighten a nut by hand. Then with a wrench to tighten a nut on 3/4 turns, keeping from rotation the union case the second wrench.
5е. To connect it was similarly the second union with the pipeline.
5ж. To pump out air and to charge system a coolant in described above sequence. At gymnastics to increase quantity of a coolant by 420 ml in comparison with nominal refuelling capacity for indemnification of additional volume of the case of the filter. If the system has been strongly polluted, replacement of a throttle branch pipe can be demanded.
