The Premier pumps require 6.4 m#/min (230 scfm) of compressed air while operating at 7 bar (100 psi) air pressure and 60 cycles per minute. Ensure that you have an adequate compressed air supply.
Refer to Fig. 2. Bring a compressed air supply line (A) from the air compressor to the pump location. Be sure all air hoses (A) are properly sized and

Keep the site clear of any obstacles or debris that could interfere with the operator’s movement.
Have a grounded, metal pail available for use when flushing the system or draining the fluid filter.
2.Air and fluid hoses: use only electrically conductive hoses.
