1. High Pressure if Compressor Receiver Dryer r Condensor2. 140 psi and start sending again when pressure gets lower during dynamic flushing high pressure can t be lt 50 or gt 140 If high pressure gets gt 200 turn off Valvel and turn on Valve 2 to release pressure It is recommended to fill Nitrogen gas into the system to increase flushing power when the high pressure system 1s blocked v After finishing dynamic flushing the bubbles decrease turn off A C 2 Static Flushing Static flushing means to flush the A C system with the ignition on and A C off it can be flushed in 2 directions O Have the ignition on but A C off Oo Switch the Power Valve to Recycling O Turn on Valve 3 amp 1 to flush the compressor then turn off Valve 3 amp 1 Turn on Valve 2 amp 4 to flush the condenser and receiver drier After bubbles decrease then turn off Valve 2 amp 4 e Turn on Valve 1 amp 4 to fill the A C system with refrigerant Turn off Valve 1 amp 4 and Turn on Valve 2 amp 3 O When finishing static flushing FR888 will automatically stops the flushing when low pressure is lt 50 psi and the red light unloading on will be turned on IV Vacuum Recover the A C System After the A C system 1s cleansed dynamically and statically from the flushing function now we need to vacuum the refrigerant out of the car O Have both ignition and A C off Oo Switch the power valve to Vacuum and turn on Valve 2 amp 3 O Turn off Valve 2 amp 3 when low pressure gauge
3. you can turn on the valve on the top of the oil tube and press Pressure to increase the speed for oil recharge Turn off the black valve below the oil tube when putting proper amount of oil into the system Input New Refrigerant to the Car A C system To put new refrigerant into car A C system turn on the Power Switch of the scale To input the volume of refrigerant please follow this procedure Clear gt Set gt g to enter the volume of refrigerant for example to input 500g need to input 00050 on number plate of the scale gt Set gt Start Zero refers to calibrate the scale to zero reading Turn on Valve 3 After filling enough volume turn off valve 3 Turn on the A C VI Service Done Check the A C System and the Temperature O Please check if the A C system is running smooth and the temperature is cool enough Oo After confirm service done it is necessary to retrieve the remaining refrigerant back to SN SAS the car Switch the power valve to Recycling Turn off the high pressure hose Turn on Valve 2 After finishing turn off Valve 2 Remove the high pressure hose and low pressure hose from the car FR888 Maintenance gt Clean and Flush the interior of FR888 lt Hook up high amp low pressure hose onto FR888 Switch the power valve to Recycling Turn on Valve 1 amp 3 or Valve 2 amp 4 to clean the system When red light Loading is on
4. User Manual for IE FR888 Coolant Flush Refrigerant Flush Recycle Recover System This system is a professional flushing machine for A C system It s unique in the way to diagnose the condition of refrigerant and oil with visual inspection through the glass window worldly patent also it s unique in the way to flush the compressor condenser evaporator and TX valve Copy Right Interequip Pty Ltd Before Start amp Preparation Open the cabin and Check if the valve is open Open the cabin and check if the valve besides the Receiver Drier is turned on The valve should be on all the time except when replacing the receiver drier see Maintenance O Drain the old oil and make sure all old oil and refrigerant is drained Note if old oil not drained it can be recycled to the machine and cause damages O Fill the Back Tank with Refrigerant Y Connect the red hose of the back tank with the red hose liquid of the 60 KG tank to fill in refrigerant Connect the blue hose of the back tank with the blue hose of the FR888 the empty tank weighs 8 kg maximum input of refrigerant 1s 20 kg v Turn on the scale and you will see the refrigerant volume into the tank max 20 kg empty tank weight 1s 8 kg v After reach the volume wanted disconnect the red hoses of the tank Fill the Scale Container with Refrigerant Option 1 Recommended Fill the scale container from the 60 ke tank Oo Connect the red hose of t
5. Valve 2 to recycle the refrigerant inside the machine back to the car A C system v Turn off Valve 2 Note If there is no refrigerant in the car A C system pls turn on Valve 1 to put in some refrigerant in the A C system until the low pressure gauge 1s 30 psi III Flush amp Recycle the A C System only when the A C system needs to be cleaned The FR888 system can perform complete flushing function including dynamic and static flushing and thus deeply clean the pipe dryer filter TX valve compressor evaporator and condenser 1 Dynamic Flushing Dynamic flushing means to flush the A C system with the ignition and A C on it can be flushed in only one direction Piping Cleansing l sscovery Y Recharge O fasanan i pa DH 7 Al vi a F rat i Have the ignition and A C on O Switch the power valve to Recycling when red light is on it means FR888 is adjusting pressure when red light and orange light are both on it means FR888 is ready for flushing O Turn on the valve 3 amp 1 first turn on Valve 3 when see refrigerant flowing through the glass window then turn on Valve 1 The system is doing dynamic flushing now and you can see the refrigerant condition in the glass window Y During dynamic flushing the mechanic needs to pay constant attention to the high amp low pressure gauge and the volume of refrigerant bubbles The system will automatically stop sending refrigerant when high pressure gets gt
