Tank Pressure Gauge - Speedaire SDR7PC05 Instructions D'utilisation Et Manuel De Pièces

OPERATING INSTRUCTIONS
IMPORTANT: Unit should be located as far from spraying area as hose will allow to prevent over-spray from
clogging intake port.
ASME Safety Valve
Check the safety valve by performing the following steps:
1. Plug the compressor in and run until shut off pressure is reached (see Operating Procedure).
2. Wearing safety glasses, pull the ring on the safety valve (see
Figure 3) to release pressure from compressor tank. Use your
other hand to deflect fast-moving air from being directed toward
your face.
3. The safety valve should automatically close at approximately
40 - 50 psi. If the safety valve does not allow air to be released
when you pull on the ring, or if it does not close automatically, it
MUST be replaced.
Regulator Knob
1. This knob controls air pressure to an air operated tool, or paint spray gun.
2. Turning knob clockwise increases air pressure at outlet.
3. Turning counterclockwise will lower air pressure at outlet.
4. Fully counterclockwise will shut off flow of air completely.
Outlet Pressure Gauge
1. This gauge shows at-a-glance, air pressure at outlet. Air pressure is measured in pounds per square inch
(psi).
2. Be sure this gauge reads ZERO before changing air tools or disconnecting hose from outlet.

Tank Pressure Gauge

Gauge shows pressure in tank indicating compressor is building pressure properly.
MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form into droplets as it comes from an air compressor pump. When humidity is
high or when a compressor is in continuous use for an extended period of time, this moisture will collect in the
tank. When using a paint sprayer, this water will be carried from the tank through the hose, and out of the gun
as droplets mixed with the spray material.
IMPORTANT: This condensation will cause water spots in a paint job, especially when spraying other than
water based paints. A filter in the air line, located as near to the gun as possible, will help eliminate this
moisture.
Do not attach air chuck or other tool to open end of hose until start-up has been
completed and unit checks okay.
Do not remove or attempt to adjust the safety valve!
