Bitzer Refrigeration Liquid Receiver FS302

Open all shut-off valves and solenoid valves

Use a vacuum pump to evacuate the entire system, including the compressor, on the suction side and the high pressure side

Measure the standing vacuum achieved

Is the standing vacuum lower than 1.5 mbar?

Repeat the evacuation operation if necessary

Ensure the compressor is not started while in a vacuum

Ensure no voltage is applied to the compressor, not even for testing

4.7 Mounting included accessory

Fit the accessories best before commissioning.

Connection positions for the included accessory, see chapter Connections, page 38, above.

Tightening torques of screws see chapter Mind when mounting or replacing, page 54 and following chapters.

After mounting, check pressure equipment for tightness.

Shut off all inlets and outlets of the pressure equipment into which something is to be installed.

Depressurise the pressure equipment.

Ensure no components or pipes are completely charged with liquid refrigerant

Verify sufficient volume is left above the liquids

Confirm only permitted refrigerants are used

Measure the precise quantity of liquid refrigerant charged

Check that the oil temperature is above 40°C

Charge the condenser or receiver directly with liquid refrigerant

Ensure blends are taken out of the charging cylinder as a bubble-free liquid

Add refrigerant on the suction side while the compressor is running, preferably at the evaporator inlet

Dispose of used oil in an environmentally friendly manner

Fill used oil into pressure resistant vessels

Fill vessels with nitrogen as a protective gas and close them

Mark vessels with the warning sign 'flammable substance' W021 from ISO7010

Verify the following components for tightness

Enter the maximum allowable pressure from the name plate

Calculate the test pressure (1.1 times the maximum allowable pressure)

Is the test pressure within the safe limits?

Test the refrigerant circuit for tightness using dry nitrogen

Record any observations or issues during the test
