Vacuum-type cooling system filler
The KVB 01 and KVB 01.1 permit repaired cooling systems to be checked for leaks and refilled free of any air pockets.
To connect the KVB 01 to the cooling system expansion tank, a radiator adapter with connecting nipple is also required
(corresponding to vehicle model – see QR-Code page 3). The KVB 01.1 is supplied complete with a UA 50 universal
adapter.
Exercise caution when dealing with a hot cooling system -> giving rise to a risk of scald injury!
Preliminary tasks/requirements
•
The expansion tank of the cooling system has to be empty.
•
Check the capacity of the cooling system (refer to vehicle user’s manual).
•
Compressed air supply at 6 - 10 bar (87 - 145 psi).
•
1 - 2 litres more than the volume of the coolant system being filled. Particles of rust and dirt must not get into the
KVB or the coolant system being filled under any circumstances.
•
It is advisable to work with a container marked with a scale showing coolant level.
•
The best results will be achieved if the coolant container is at the level as the expansion tank in the vehicle.
•
Set the heating control switch (in the vehicle) to the ‘high heat‘ position.
Before using the device, we recommend that you perform a test of the radiator vacuum-filling device.
•
Connect the venturi nozzle at the radiator vacuum-filling device, the shut-off valves V1 and V2 are closed. Supply
compressed air to the venturi nozzle.
•
Open shut-off valve V2. The vacuum display on the vacuum gauge must be in the green area.
•
Close shut-off valve V2. Disconnect compressed air supply. The vacuum display must remain constant! (vacuum
integrity). In this way the user can ensure a) that the compressed air supply is OK,
b) that the device is in a proper working condition.
•
After completion of the test, open ball valve V2 again (= atmospheric pressure).
•
The vacuum display must be 0, if the display does not show 0, the vacuum gauge is defective.
1. Directions for use
•
Remove radiator cap. Press-fit model-related adapter K.., KS.. or screw
mount universal adapter UA... to the expansion tank filler neck.
•
(See illustr. 1, page 2) Connect KVB at (E).
•
(See illustr. 2) Take care to ensure that stopcocks V1 and V2 are closed.
•
(See illustr. 3) Connect venturi tube (C) to KVB.
•
(See illustr. 4) Connect nozzle to workshop compressed air supply. Note:
The venturi nozzle makes a hissing noise. This is normal.
•
(See illustr. 5 + 6) Bleed the filling tube (A). Open stopcock V2. Immerse
filling tube (A) in coolant and secure against slipping. Open stopcock V1.
The filling tube (A) will now fill with coolant. Do not close V1 until the
filling tube (A) is free of air pockets. Surplus coolant will be discharged
through tube (D). Have a container ready to catch this coolant.
