Basic maintenance of the cooling system

The service valve of the refrigerant tank

PERFORMANCE ORDER

1. Before connecting the valve to the tank with coolant completely turn the knob counterclockwise.
	2. Turn the drain valve clockwise to the full.
3. Remove the drain valve by hand clockwise to the full. Connect the center hose to the nozzle valve.
4. In order to perforate the sealed container, turn the knob clockwise.
	5. To fill the central hose turn the knob clockwise to the full. To fill the central hose turn the knob clockwise to the full.
6. Loosen the nut of the hose attached to the central fitting manifold gauges. Vent. Then re-tighten the nut.

Installing the collector with pressure gauges

A warning

Fittings for the installation of a set of manifold gauges are mounted on the tubes of high and low pressure.

PERFORMANCE ORDER

1. Close both manifold valves set with pressure gauges.

2. Connect the low pressure hose to the high pressure nipple.

3. Tighten hose nuts, but only by hand.

Tightness test

After removing the air from the system, check for leaks.

PERFORMANCE ORDER

1. Connect the full capacity of the refrigerant to the service valve.
	2. Open the valve of the high pressure refrigerant gas fueling system.
3. On reaching the pressure gauge of low pressure 98 kPa (1 kg / ^cm 2) close the valve of high pressure.
	4. To check the tightness of the system use gas leak detector. If you find leaks and repair the faulty node or connection; then remove air from the system.

Draining the system

PERFORMANCE ORDER

1. Connect a set of manifold gauges to the cooling system.
2. The free end of the central hose lay on the operating towel.
	3. To drain the coolant slowly open the high-pressure valve.
A warning Open the valve only slightly. Assuming sink with too high speed, the system runs out of the compressor oil.
4. Check the operating towel to ensure that the oil does not flow. If you have a little bit of oil, cover the valve.
5. After reducing the pressure gauge is included with manifold gauges to 343 kPa (3.5 kg / ^cm 2) slowly open the valve on the low pressure.
	6. As the pressure drop in the system gradually open the valves of high and low pressure until the readings of both gauges the level of 0 kPa.

Venting

Whenever the cooling system is connected to the atmosphere, it must be purged to remove moisture and air.

PERFORMANCE ORDER

1. Connect a set of manifold gauges.
2. Connect the central hose set of gauges to the input of the vacuum pump.
	3. Run the vacuum pump and open both valves.

4. When the low pressure gauge shows approximately 750 mmHg, close both valves and stop the vacuum pump.
5. Check the constant pressure for at least 5 minutes. In case of change of pressure, check the tightness of the system and, if necessary, repair it.
	6. In the absence of leaks, disconnect the hose from the vacuum pump.

Charging

PERFORMANCE ORDER

1. Remove the air from the cooling system.
2. Connect the refrigerant container with a hose set to a central manifold gauges.
	3. Open the valve on the high pressure side of the system for charging refrigerant gas. The amount of refrigerant is charged through the high side: 400 g
4. Close the valve of the high pressure manifold gauges set.
5. Start the engine and turn the work of the compressor.
A warning Try to keep the capacity of opening up to avoid charging system with liquid refrigerant through the suction side, which can damage the compressor. Never open the valve high pressure side when charging system when the air conditioner is on. It is not a departure from the norm, if you hear the murmur of the charging process.

6. Open the valve of the low pressure manifold gauges set.
7. Charge system set amount of refrigerant. The total amount of refrigerant: 700 g
8. Close the valve of the low pressure side and the service valve of the refrigerant tank.
9. Stop the engine.
	10. Remove the manifold gauges set.

The functional test

After repairs are completed, perform the test of the air conditioning system to function in the following order.

PERFORMANCE ORDER

1. Connect a set of manifold gauges.
2. Start the engine and keep the engine speed of the engine 1500 min-1.
3. Turn on the air conditioner to maximum cooling.
4. Open all windows and doors.
5. In the center of the outlet of the fan, place a dry thermometer.
	6. Place the thermometer with dry and wet bulb near the inlet of the main fan.
7. Wait until the temperature stabilizes at the outlet of the air conditioner. Steady state The inlet temperature of the main fan: 25-35 ?� C High-pressure side: 1177-1619 kPa
A warning If too high, the pressure on the high pressure side obleyte cold water condenser. Excessive lowering it close the front part of the condenser.

8. After stabilization of the temperature at the outlet of the air conditioner remove the thermometer with dry and wet bulb placed in the air intake duct.
	9. Calculate the relative humidity with the help of the graph using the thermometer with dry and wet bulb.
10. Read the dry bulb temperature set in the air intake channel, and calculate the difference between the readings dry thermometers installed at the inlet and outlet channels.
	11. Check if the point of intersection of relative humidity and temperature differences in the shaded area.
