IMPORTANT:
The safety valves supplied with this equipment are designed and constructed for use exclusively with compressed air, free from
impurity. The materials used in construction are suitable for operating the valve at the rated pressure and temperatures. The viton or NBR gasket
conserves the resistance characteristics, even in prolonged use. The valve caulking is designed to impede calibration, modification or tampering.
Any modification or recalibaration of the safety valve will nullify warranty and potentially make the equipment unsafe.
Valve installation must be performed exclusively by Jefferson approved engineers. Checking the integrity of the valve before installation is
obligatory. Also, check that the valve pressure is no greater than the operating pressure of the tank or of the system that it is installed with.
•
Check that the discharge flow rate of the valve is greater than the quantity of the air to discharge.
•
The safety valve must be positioned directly on the tank in a vertical position, in a dry, accessible place protected against the weather and far
away from liquids or condensation.
•
It must be positioned to allow sufficient space all around for correct air discharge, without causing damage to persons or the surrounding
area.
•
The valve rod must be free in its movement when discharging.
•
The connection between the valve and the part to be protected must be free from all kinds of choking and be as short as possible so as not
to reduce the discharge flow rate of the valve itself.
•
The connection passage area must be greater than the valve orifice area.
•
During installation screw on the valve with a torque spanner using the hexagonal part of the body.
•
Apply a maximum torque of
30Nm
, paying attention not to cause any deformation; using pincers, pliers, hammers or tools other than a
hexagonal spanner is forbidden and will void warranty.
•
Check that the inlet hole and the shutter are not blocked by glue, Teflon or similar materials that could bind the shutter or other functional
components.
•
If the valve is replaced the compressed air contained in the system must be discharged first.
WARNING:
Jefferson Tools cannot take any responsibility for damage caused to persons and/or things due to failure to observe these instructions.
ON/OFF SWITCH
Prior to connecting the compressor to the power supply, ensure the pressure switch is on
the
OFF
position. On initial start-up open the reservoir condensate drain bung (
A
) (
Fig.10
, adjust the pressure regulator (
B
) (
Fig.11)
to the maximum pressure. Unscrew the bung
anti-clockwise to open valve.
Pull the pressure switch (
C
) up to start the compressor.
NOTE:
The switch may be a "Lever" or "Button" type as shown in (
Fig.11
), depending on
your compressor model.
Allow the machine to run for 10 minutes with the air escaping from the reservoir tank
before closing the drain bung (
A
).
Ensure the tank pressure reaches 10 bar as indicated on the gauge (
D
) before the
pressure switch shuts off the motor.
NOTE:
When the drain bung is closed the tone from the motor will change. The
compressor motor will automatically restart when the tank pressure drops to approximately
3-4 bar less than the maximum pressure.
WARNING:
Never stop the compressor using the mains connection. Always switch off
the compressor by pressing the pressure switch button down. The compressed air will be
vented from the head and allowing an easy re-start.
NOTE:
During correct operation a whistle of compressed air escaping/releasing will be
heard when the motor strops and a protracted whistle (approx. 20-30 seconds) whenever
the compressor is started with no pressure in the tank.
