Setting up the DR3 / DR5 Auto Drafter
Your Auto Drafter requires a 240v power supply, or 12v battery and compressed air supply.
Please read and understand the instructions before operating your Auto Drafter.
The compressor
We recommend a 7 or 8 cfm belt driven compressor capable of a minimum of 90 psi. If the
compressor is too small the Racewell will run slowly and may not operate properly.
The compressor does not need to be close to the Racewell, in fact having it at some distance
reduces noise levels in the working area. It is important to run compressors in a well ventilated
area as close as possible to a main supply near a switchboard – this avoids the use of leads which
can affect the power input. From time to time the oil level on the dipstick should be checked.
Water should be drained from the air reservoir, after every use.
Please note : when turning the compressor on or off use the switch on the compressor
and not the switch at the power source.
This applies to all compressors, because air is not discharged, the compressor is being asked to
start under load and this can burn out its capacitor.
Attaching the air fittings and connecting the compressor
Pipe the air from the compressor to the Racewell via standard a 15mm (1/2 inch) alkathene water
line. We have some Racewells working with the compressor up to 2kms away from the work site.
If your compressor is situated some distance from your Racewell we recommend the airline
configuration shown here.
This provides a purge tap or ball valve, which allows condensation to be periodically removed
from the air system. Assemble the airline and connect to the compressor. Plug the compressor
into a power source and turn on. Finally, turn the compressor on. Always turn the compressor on
or off at the unit and not the power source.
