Bitzer Refrigeration Liquid Receiver FS1602

Check for abnormal vibrations in the system, particularly the pipelines and capillary tubes.

Were additional safety measures required due to vibrations?

Ensure pipes are connected to the pressure equipment without load and stress to prevent mechanical stress.

Handling Flammable Refrigerants

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

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 out extremely precise quantities of refrigerant

Ensure 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

4.7 Mounting included accessory

Fit the accessories best before commissioning.

Check connection positions for the included accessory in chapter Connections, page 38.

Check tightening torques of screws in 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.

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

Record 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
