coupling half to put the valve to the gas pipe. - Make control soldering joints on all sides using

The set of equipment, tools and materials to replace the motor - compressor on the R-12, R-134 - Portable equipment for evacuation and filling - welding station or torch with MAPP gas - leak detector - electronic thermometer - a small pipe cutter - to survive - charging cylinder - set tools and equipment - motor - compressor - filter dryer - 6mm copper pipe - solder - flux - freon
Safety point of entry measures: - repair all equipment must be grounded, refrigeration unit is turned off. In the absence of grounding and residual current device, the work is performed with an insulating pad. - After each refueling and release refrigerant, before performing soldering needed to ventilate the room at least 15 minutes. Smoking point of entry is not allowed, including point of entry heaters - with the tightness test guide "Safety Regulations for freon refrigeration installations" - soldering joints refrigeration units on site must be carried out in compliance with the "Instructions for fire safety in the repairs of household point of entry refrigeration units compression refrigeration point of entry equipment in a residential premises point of entry ".
Replacement procedure: 1. Dismantle the defective compressor. - Determine the cause of compressor failure (defective compressor, freon leak, clogged capillary tube defects defrost system) - a file incision filling pipe and break off her
- An incision in the capillary tube at a distance of 20-30 mm from the filter drier and break off her - a pipe cutter to cut the discharge and suction tube at a distance of 10-20mm from compressor-weld pipe - a pipe cutter to cut the filter drier at a distance of 10 to 15 mm from the weld filter- capacitor and remove - dismantle puskozaschitnoy relay with motor - compressor - Remove compressor mounting to traverse the cooler - remove the compressor with crosshead - clean pipe solder a new compressor
2.Montazh new compressor. - To fix a new compressor on the traverse cabinet refrigerator - remove the plugs from the compressor fittings, producing depressurization compressor no earlier than 5 minutes before soldering. When removing the check stub overpressure air compressor. Checked for the presence of noise of escaping air when removing the plugs. - Dock with the compressor discharge pipes, suction tube, filling tube - length 60 mm, diameter point of entry 6mm - make solder joints in the sequence filling, suction, point of entry blowing tube. Do not point the flame inside the tube compressor. In the compressor on the suspension and muffler inlet, point of entry near the operating nozzle, used plastics, flame hit on the plastic will lead to compressor failure - increased noise during start-up and operation. - Remove the plugs from the filter-drier, install a filter on the capacitor and insert the capillary tube - make solder joints filter
coupling half to put the valve to the gas pipe. - Make control soldering joints on all sides using a mirror, seams should be flat and smooth availability nepropaev unacceptable. When soldering joints copper-copper, copper-phosphorus brazing alloys prepared by the joint is placed between the burner and the screen is heated to 600 C (dark cherry point of entry color copper). Preheated solder dipped point of entry in flux, melted by pressing the rod to the heated joint. When soldering joints copper-steel and steel-steel used silver-solder. Warming up is carried out at a temperature of 900 C (light red copper). When soldering make sure that the solder joint to lay evenly on all sides. Immediately after hardening joints should wipe them with a cloth moistened with water to remove flux residues.
3. Filling the cooling unit. - Never refuel the Freon R-134 in refrigeration unit operating to repair on the R-12 or R-600. When installing the compressor (on the R-134 or R-12) on the cooling unit, designed for R-134, is allowed to refill the cooling unit mixed refrigerant R-406a, S10M1 G. allowed on cooling unit operates on R-12, set the compressor on R -12, R-134 and fill blend refrigerants. - Connected to the clutch vacuum point of entry - gas station to produce, the primary evacuation of the refrigeration unit to a residual pressure of 64 Pa.
Evacuating the system - the process of creating a system of sub-atmospheric pressure. The main purpose - to delete from the system water. This occurs as follows. By lowering the pressure lowers the boiling point of water. The moisture in the system is vaporized at ambient temperatures and is sucked by vacuum pump. In the presence of moisture in the system, at high temperatures chlorofluorocarbon is reacted with water to form acid which corrodes the system nodes. Water freezes in the smallest with
