5. operation
5.1.
installation refer to fig.1
the dye reservoir assembly (2) is designed to be used with air conditioning coolant recovery/recycling equipment. connectors
provided allow for permanent connection, see fig.1. supplied with the kit are two connectors (3 & 4) enabling connection to types
r134A and r12 recovery/recycling systems.
5.1.1. evacuate the pipes on the recovery/recycling equipment and disconnect the low pressure hose located on the recovery/
recycling equipment.
5.1.2. connect the kit hose (2) to the low pressure connector on the recovery/recycling equipment.
5.1.3. connect a low pressure hose from the injector equipment to the vehicle.
5.1.4. check that the injector valve of the dye reservoir assembly (2) is open and the injector threaded cap is tightly closed.
5.1.5. evacuate the recovery/recycling equipment.
5.2.
dye injection - a/c system under vacuum or low pressure refer to fig.2
5.2.1. recover the remaining coolant and set the system under vacuum.
5.2.2. close the injector valve (2) and unscrew the threaded cap. ensure the cap seal ring is fitted and undamaged.
5.2.3. Pour one bottle of dye (5) into the reservoir and then screw the cap back on, firmly.
5.2.4. open the injector valve that is between the equipment and the car.
5.2.5. start the recovery/recycling equipment loading function. the air conditioning system will be charged with coolant and dye.
5.2.6. When the required system loading level is reached stop the recovery/recycling equipment, leaving the injector valve open.
5.3.
dye injection - a/c system under pressure refer to fig.2
5.3.1. It requires a minimum of approximately 450g of coolant to flow through the injector to ensure that all the dye is transferred to the
A/c system. therefore recover this amount, or more, from the system.
5.3.2. close the injector valve.
5.3.3. Warning! the injector is pressurised. remove the threaded cap
5.3.4. Pour one bottle of dye (5) into the reservoir and then screw the threaded cap back on, firmly.
5.3.5. open the injector valve that is between the equipment and the car.
5.3.6. start the recovery/recycling equipment loading function. the air conditioning system will be charged with coolant and dye.
5.3.7. When the required system loading level is reached stop the recovery/recycling equipment leaving the injector open.
5.4.
dye injection with a manometric unit refer to fig.3
the dye injector can also be used with a manometric charging system, as shown in fig. 3 .
5.4.1. connect a low pressure hose from the recovery/recycling equipment to the low pressure fitting (A).
5.4.2. Follow the instructions as for use with the recovery/recycling equipment.
5.4.3. to start the coolant flow open the low pressure valve (B) of the manometric unit.
5.5.
leak detection
note: leaks will be more apparent if the uV inspection is carried out in low ambient light.
5.5.1. run the air conditioning for at least 10 minutes to distribute the dye throughout the system and then turn off the engine.
5.5.2. connect the uV lamp to the vehicle battery terminals, or other suitable 12 volt supply, noting that correct polarity (red clamp to
positive terminal) is important.
5.5.3. Wearing the uV safety goggles, point the uV lamp at the area to be inspected and then press the switch to turn it on. switch off
the lamp while redirecting it to the next area of interest. Warning! the lamp gets hot during use. do not touch the lens, do
not place the lamp near inflammable material and do not return the lamp to the case until it has cooled. leaks will become
apparent as the dye will fluoresce under the uV light.
