To remove the shipping blocks, first loosen and remove the 2 bolts located at the ends of the
inner baseplate (see Figure 1-1). Then remove the 2 shipping blocks which are accessed
through the 2 forklift slots in the frame, intake filter side of unit. To simplify removal, a short piece
of wire is attached to each block. Grab the wire and extract the block through the slot in the
frame.
For best vibration control, the 4 spring isolators may require slight adjustment to match each
compressor, or compensate for any off-level floor conditions. A bolt with lock nut is provided at
each corner for this purpose. The inner and outer bases should be approximately flush with each
other, if the springs are properly set.
Do not install isolating valves between compressor outlet and air receiver. This will cause
excessive pressure if valve is closed, and cause injury and equipment damage.
Always use an air pressure regulating device at the point of use. Failure to do so can result in
injury or equipment damage.
 Do not install in an area where ambient temperature is below 30 degrees F or above
100 degrees F.
 Do not install unit in an area where air is dirty and/or chemical laden.
 Unit is not to be installed outdoors.
