4.1
Safety
To avoid the risk of burns,
do not touch pipework or stand next to
venting valves.
If there is a risk for any reason we recommend the use
of heat resistant gloves/clothing.
For safe use, the maximum speed should not exceed 3000 rpm and the
maximum pressure should not exceed 2.0 bar gauge.Where the operator
will be subject to prolonged exposure to noise, it is recommended ear-
plugs should be provided. Drum International’s own tests show noise
levels for the D9000 to be between 88 to 90 dB(A) at above operating
figures
4.2
Starting the compressor
Check that the Power Take Off is
disengaged
then start the engine.
NOTE :
The D9000 should not be started against full discharge pressure. Depressurise
by operating the pressure relief valve before starting the D9000 unit.
Set the engine speed to tick over.
Depress the clutch and allow a minimum of 5 seconds for the gears to stop rotating.
Engage the PTO.
SLOWLY release the clutch.
Check that the D9000 is producing air.
Set the engine speed to give a compressor operating speed between 1800 rpm and
3000 rpm as required.
NOTE :
Avoid starting and stopping the compressor against pressure.
Return engine speed to tick over before disengaging the PTO.

OPERATING INSTRUCTIONS
3.6.4 Silencers.
An outlet silencer is integral with the unit and is situated underneath the compressor.
An inlet silencer is built into the lid assembly.
3.6.5 Discharge filter (not supplied).
Drum can supply an inline micronic discharge filter (Rated at 5 microns) to remove
contaminants in the discharged air. Filters of this type are essential for use with foodstuffs.
When fitted, discharge filters should be fitted after any valves in the system.
3.6.6 Discharge pipework.
The discharge pipework can reach temperatures of 200 degrees Celsius.
It is recommended that all discharge pipework be guarded and a warning label attached to
warn the operator of the danger of burns.
Combustible material must not come into contact with the discharge pipework.
Where possible the discharge pipework should be isolated from direct transmission of vibra-
tion to the vehicle chassis.
